26/11/17: FAANGS+ Brewing up another markets storm


One of the key signals of a systemic mispricing of financial assets is concentration risk. I wrote about this in a number of posts on the blog, so no need repeating the obvious. Here is the latest fragment of evidence suggesting that we - the global financial markets and their investors - are at or near the top of froth when it comes to 'irrational exuberance':  http://www.zerohedge.com/news/2017-11-26/david-stockman-derides-delirious-dozen-2017.

So what should investors do? Some lessons from the GFC that can help are summarized here: http://trueeconomics.blogspot.com/2017/11/241117-learning-from-gfc-lessons-for.html. And some additional warning signs of the bubble are summarized here: http://trueeconomics.blogspot.com/2017/11/191117-next-global-financial-crisis.html.

Quote: "...our new Delirious Dozen consists of the FAANGs (Facebook, Apple, Amazon, Netflix and Google) plus seven additional high flyers (Tesla, NVIDIA, Salesforce, Alibaba, UnitedHealth, Home Depot and Broadcom)."

What the above valuations imply?

  •  "Amazon is now valued at $550 billion and thereby trades at 293X its $1.9 billion of LTM net income" - EV/EBITDA ratio of x46.5
  • "Broadcom trades at 246X net income"
  • "Netflix is valued at 194X" or x107.8 EV/EBITDA ratio
  • "Salesforce (CRM) ... is currently valued at $77 billion, and Tesla, which sports a market cap of $54 billion. Yet both had large net losses during the latest 12 months. In fact, during the last five years, CRM has posted cumulative net losses of $650 million and Tesla has lost $3.3 billion." Enterprise Value/EBITDA for CRM is now x154; for Tesla: x80.7 after  the recent price drops.
  • NVIDIA sports EV/EBITDA ratio of x44.9 and Alibaba of x43.5
  • UnitedHealth is absolutely cheap at x13.3 EV/EBITDA as is Home Depot at x13.9 although the latter does sport a P/BV ratio of x57.3 and that is before it takes a full writedown on the 'value' of its stores, in lines with forward expectations of the changes in the retail environment in the near future
  • Facebook EV/EBITDA is x26.6 with expectations forward on earnings bringing trailing P/E ratio from x41 to x27.6 which is really equivalent to saying that there is no business cycle that can impact adversely Facebook's business any time soon.
  • Apple's EV/EBITDA is x13.3 - cheap by all 'FAANGS' measures, but forward relative to trailing P/Es imply earnings growth of at least 35-40 percent in 24 months horizon. Which is, again, suggesting no one should ever expect any clouds on Apple's horizon.
  • Google's EV/EBITDA is x19, while forward vs trailing P/E ratios imply earnings growth of at least 33-40 percent, similar to Apple's.
There is, quite clearly and transparently, an eyes wide shut moment for the markets. Greenspan might have called this the 'irrational exuberance', while your friendly sell-side broker will undoubtedly call it 'time to buy into the market' moment. But you have to have guts of steel and brain the size of a pea to not spot the trouble ahead with the current markets valuations.

21/11/17: ECB loads up on pre-Christmas sales of junk


Holger Zschaepitz @Schuldensuehner posted earlier today the latest data on ECB’s balance sheet. Despite focusing its attention on unwinding the QE in the medium term future, Frankfurt continues to ramp up its purchases of euro area debt. Amidst booming euro area economic growth, total assets held by the ECB rose by another €24.1 billion in October, hitting a fresh life-time high of €4.4119 trillion.


Thus, currently, ECB balance sheet amounts to 40.9% of Eurozone GDP. The ‘market economy’ of neoliberal euro area is now increasingly looking more and more like some sort of a corporatist paradise. On top of ECB holdings, euro area government expenditures this year are running at around 47.47% of GDP, accord to the IMF, while Government debt levels are at 87.37% of GDP. General government net borrowing stands at 1.276% of GDP, while, thanks to the ECB buying up government debt, primary net balance is in surplus of 0.589% of GDP.

Meanwhile, based on UBS analysis, the ECB is increasingly resorting to buying up ‘bad’ corporate debt. So far, the ECB has swallowed some 255 issues of BB-rated and non-rated corporate bonds, with Frankfurt’s largest corporate debt exposures rated at BBB+. AA to A-rated bonds count 339 issues, with mode at A- (148 issues).


It would be interesting to see the breakdown by volume and issuer names, as ECB’s corporate debt purchasing programme is hardly a very transparent undertaking.

All in, there is absolutely no doubt that Frankfurt is heavily subsidising both sovereign and corporate debt markets in Europe, largely irrespective of risks and adverse incentives such subsidies may carry.

20/11/17: Tallying the Costs: U.S. Wars in Iraq, Afghanistan & Pakistan


The folks at Brown University have carried out the most detailed assessment of the disastrous costs of the U.S. wars fought since 9/11. The details can be found here: http://watson.brown.edu/costsofwar/. These are a must read!  While Russia stands accused by the U.S. of triggering the humanitarian crisis through its intervention in Syria (the civil war that started with the U.S. support and blessing), here is Brown University's conclusion about the real refugees crisis:

Not to say that one wrong (U.S.) makes another wrong right (Russia), but 10.1 million estimated refugees caused by the U.S. wars? This got to stand out, folks.

The U.S. has spent estimated USD5.6 trillion from 9/11 through fiscal year 2018 according to the study.


Enough to buy healthcare for every American, or to pay all outstanding student debt. Hell, in fact, it would have allowed for both.


And the above costs and impacts do not account for Libya, Egypt, Yemen and other direct and indirect 'minor' conflicts the U.S. has been involved in. The statistics do not include Syria.

In a recent post, I mused about the asymmetric warfare and the fact that, seemingly, outspending the entire world in terms of defense expenditures, the U.S. appears incapable of achieving its core objectives (see the post here: http://trueeconomics.blogspot.com/2017/09/12917-asymmetric-conflicts-and-us.html).

There appears to be no learning curve from the past 16 years - neither in the public minds (who support increasing expenditure on military industrial complex) and in the mind of the Washington politicians (see http://www.tomdispatch.com/post/176335/tomgram%3A_andrew_bacevich%2C_how_we_learned_not_to_care_about_america%27s_wars/#more).

And there is neither an increase in transparency in the American policies post-9/11, nor an increase in scrutiny of choices made (see http://watson.brown.edu/costsofwar/files/cow/imce/papers/2017/Linda%20J%20Bilmes%20_Credit%20Card%20Wars%20FINAL.pdf):


As folks from Brown University project conclude: "The wars have been accompanied by violations of human rights and civil liberties, in the US and abroad. The wars did not result in inclusive, transparent, and democratic governments in Iraq or Afghanistan... The human and economic costs of these wars will continue for decades with some costs, such as the financial costs of US veterans’ care, not peaking until mid-century. US government funding of reconstruction efforts in Iraq and Afghanistan has totaled over $170 billion. Most of those funds have gone towards arming security forces in both countries. Much of the money allocated to humanitarian relief and rebuilding civil society has been lost to fraud, waste, and abuse."

This is genuinely frightening!

20/11/17: Your Family Doc, Called AI...


In a recent post, I wrote about the AI breaching the key dimension of 'intelligence' - the ability to self-acquire information and self-replicate knowledge (see http://trueeconomics.blogspot.com/2017/10/221017-robot-builders-future-its-all.html).  And now, Chinese AI developers have created a robot that is capable of excelling at (not just passing) a medical certification exams: https://futurism.com/first-time-robot-passed-medical-licensing-exam/.

Years ago, working for IBM's think tank, IBV, I recall discussions about the future potential applications for Watson. Aside from the obvious analytics involved in finance (my area), we considered the most feasible application for AI and language-based software in... err... that's right: medicine. More precisely, as family doctors replacement. For now, Watson is toiling primarily in the family doctors' support function, but truth is, there is absolutely no reason why AI cannot currently replace 90% of the family doctors' practices.

And, while we are on the subject of AI, here is an interesting article on how China is beating the U.S. (and by extension the rest of the world) in the AI R&D game: https://futurism.com/china-could-soon-overtake-the-us-in-ai-development-former-google-ceo-says/ and https://futurism.com/china-has-overtaken-the-u-s-in-ai-research/.

Still scratching your heads, Stanford folks?.. 

20/11/17: Bitcoin: an Unknowable Bubble?


There is a much-discussed in the crypto-sphere chart making rounds these days, plotting Bitcoin price dynamics against the historical bubbles of the past:


The chart is striking. Albeit simplistic. See Note 1 below for a technical argument on the chart timing.

On price dynamics alone, Bitcoin looks like a sure bubble - a disaster waiting to happen. But Bitcoin dynamics are basically not suited for any empirical analysis of any significant accuracy.

As noted by some commentators, Bitcoin had numerous 80-90% and larger drawdowns in the past (given its immense volatility). It keeps coming back from these. Some claim this to be the evidence that Bitcoin it not a bubble. Which is neither here nor there: bubbles are generated by exuberant expectations of investors, not by actual parameters of price processes. Causality does not flow from dynamics to bubbles, but the other way around. So to identify a bubble, one needs to identify exuberance. See Note 2 below for more on 80% drawdowns.

In the case of Bitcoin fans, there is clearly such.

No investor or serious analyst has been able to provide a fundamentals-based valuation model for Bitcoin.

A disclosure in order here: myself and a graduate student of mine have looked at the fundamental modelling for Bitcoin over the summer. We found no tangible relationship between any economic or financial parameters tested and Bitcoin price dynamics. In another piece of research, myself and two co-authors are currently looking at empirical dynamic and fractal properties of Bitcoin. Again, we finding nothing consistent with a behaviour of an asset with fundamentals-derived valuations.

Absence of evidence is not the same as evidence of absence. But, taken together with the general lack of credible fundamentals-linked modelling of the crypto-currency, this means that, at this point in time, Bitcoin price can be potentially driven solely by… err… expectations held by its enthusiasts, plus the incentives by the predominantly China-based investors to avoid extreme risks of capital controls and expropriations. If so, both drivers would make it a speculative bubble.

The only quasi-fundamentals-linked argument for Bitcoin has been the blockchain one - the promise of Bitcoin serving as a key tool for data aggregation, recording and transmission. This argument, however, no longer holds. Blockchain technology has migrated from public blockchains, like Bitcoin, to either open blockchains, like Ethereum or, increasingly more frequently, private blockchains. It is the latter that currently hold the promise to serve as viable platforms for data economy.

As a libertarian, I should like a private currency system that supports anonymity of transactions. As an economist, I should like the innovative nature of Bitcoin. And, put simply, I do. Both.

But as an investor, I do not have the stomach for Bitcoin’s valuations and volatility, as well as for its higher moments behaviour (in particular worrying are kurtosis, co-skews and co-kurtosis, which severely complicate empirical dynamics analysis, see Note 3 below). And I have even less enthusiasm for the crypto market that is sustained increasingly by undertakings, like BitMEX - a purely speculative platform trading some $35 billion in Bitcoin derivatives with leverage up to x100 to the amateur speculators who, put frankly, have zero idea what they are buying and at what price. The vast majority of Bitcoin investors have no clue what a butterfly option looks like and how it can be valued. And the vast majority of financial markets analysts and professionals won’t be able to price a butterfly strategy for Bitcoin, given its painfully twisted moments. Yet, within a month of starting trading, BitMEX reached 1/3 of the market capitalisation of Bitcoin. This is not just a shoe-shine-boy moment, folks. It is white-powder-under-the-nose-and--empty-bottles-of-vodka-on-the-floor hour for high school dropouts with cash to burn.

Another worrying issue with Bitcoin is the argumentation of its main supporters.

This ranges from the cognitively biased “you don’t know anything about the Bitcoin” to “Bitcoin is scarce & limited in supply” to “Bitcoin is a promise of liberating the masses from the oppression of the Central Bankers”.

The first sort of argument exhibits not just Jurassic ignorance of logic, but also a gargantuan dose of arrogance. Repeated sufficiently enough, it signifies the absurd degree of exuberance of investors’ expectations.

The second argument is patently false. Bitcoin has undergone splits, and engendered dozens of other cryptos, with unlimited supply of such into the future. Bitcoin itself is divisible ad infinitum and, with forks, its supply is potentially unlimited. Worse, Bitcoin rests on man-made mathematical foundations. Which means it has no physical bound or constraint. Anything man-made (and even more so, anything mathematically derived) is, by definition, fungible and axiomatic. Just because to-date no one cracked the code to alter Bitcoin mid-stream or drain blockchain-held information does not mean that in the future such a code cannot be written. So hold your horses: gold is physically limited in quantity (even though in the Universe, it is not as scarce as it is on Earth, which makes long term supply constraint on gold potentially non-binding). Bitcoin is limited by our capacity to alter the underlying code defining it. Anyone thinking of an algorithm as a 'law' needs to go back to Godel's mathematics.

Finally, there is an argument of ‘liberation’. Bitcoin value is only sustained as long as it remains convertible into goods, services and other currencies. This means that Bitcoin cannot remain a government- regulation-free asset, as long as its popularity as a medium of exchange and a vehicle for store of value grows. Which means that in the medium terms (3 years or so?), Bitcoin will either cease to be, or cease to be anonymous. All protection from the dictate of the Central Bankers will be gone.  Benign tolerance of Bitcoin by some regulators can quickly turn into outright prohibition on trading - as current and past examples of China, Vietnam, Nigeria, Colombia, Taiwan, Ecuador, Bangladesh, Kyrgyzstan and Bolivia, Russia, and Thailand suggest. Evolution of cybersecurity measures and regulatory and supervisory tools, including their spread into cryptocurrencies domain will only increase effectiveness of such measures into the future. So, unless you are planning to live in a libertarian paradise, where legal norms of other states do not apply, good luck committing much of your wealth to Bitcoin as a safe haven for oppressive or coercive actions of the nation states.

Worse, anyone claiming that Bitcoin is a hedge against inflation fails to understand how modern markets work. Again, to increase in value, Bitcoin requires higher rates of adoption. Higher rates of adoption bring about higher rates of asset instrumentation (see above for BitMIX). Higher rates of instrumentation and adoption, taken together, imply higher holdings of Bitcoin by institutional and diversified portfolio investors. So far so good? Right, now the kicker: these holdings imply greater, not lower, positive correlations between Bitcoin and other asset classes in shock-experiencing markets. That's right, dodos: Goldman holdings of Bitcoin are correlated to liquidity supply in general markets, because if such liquidity starts evaporating, Goldman will sell Bitcoin to plug holes in other instruments. Sell-off in the markets can trigger sell-off in Bitcoin. Now, another kicker: Bitcoin is currently less liquid than any major asset class (see extreme volatility of pricing across various Bitcoin exchanges). Which means that smart folks at Goldman will be dumping Bitcoin before they dump gold and other assets. Hipsters hugging their laptops will be the last to wake up to this momentum (behavioural evidence suggests, they might actually buy into falling Bitcoin in hope of speculatively gaining on a bounce, which, incidentally, can explain why large drawdowns in Bitcoin can turn so fast into upward trends).

The tricky bit about Bitcoin is that its enthusiasts need to learn to live in the real world first. Until they do, Bitcoin will continue its upward path, and this process can go one for quite a while, depending on the supply of cash in the markets for Bitcoin. Once they are taught a sufficient lesson, however, the rest of us will be learning the long term fundamentals valuations of Bitcoin. I, for now, have no idea what these valuations might be.

So Bitcoin, then. A bubble or not? If you ignore the arguments that attempt to justify its valuations, it looks like one, albeit with dynamics that are very hard to interpret. If you listen to them, it looks that way even more, with more confidence in the arguments bogus nature. Draw your own final conclusions.



Note 1: In defence of the chart above, without validating its implied conclusions: the chart plots Bitcoin evolution from 3 years ago through today. This starting point makes sense. Until mid-2014, Bitcoin was extremely obscure, hype-only investor vehicle, with volatility so off the charts, any analysis of its dynamics was futile (I know, I did such analysis and presented the results in my talk at Bloomberg two years ago). Those us who do research in finance generally and routinely disregard the first 3-4 years of existence of Bitcoin for exactly that reason.

Note 2:  A note due here: Bitcoin's returns from 80-90% drawdowns is not a solid evidence of the crypto-currency not being a bubble, because they are in line with Bitcoins' overall massive volatility. In other words, a valid comparative for these drawdowns relative to other asset classes is not "an 80% drawdown in  Bitcoin ~ an 80% drawdown in stocks", but "an 80% drawdown in Bitcoin ~ an 8% drawdown in stocks". Apples to apples. Dust to dust.

Note 3:  Interesting Elliott Wave analysis of Bitcoin dynamics here: https://atozforex.com/news/29-september-bitcoin-elliott-wave-analysis/ and here https://www.cnbc.com/2017/07/20/bitcoin-bubble-dwarfs-tulip-mania-from-400-years-ago-elliott-wave.html, although I am not convinced Bitcoin price trends are established enough for this technique to work.

20/11/17: Russian economic growth slides. Structural issues loom large


An interesting view of the Russian economy (as usual) from Leonid Bershidsky: https://www.bloomberg.com/view/articles/2017-11-14/russia-s-economy-is-growing-with-borrowed-money

Credit, is not a sustainable source for growth in Russia, especially as the Russian households’ leverage capacity (underpinned by expected future wages) is not exactly in rude health. A recent study from the Russian government's own Analytical Center found that roughly 17% of the working population, or about 12.1 million Russians, can be classified as the working poor - those earning less than enough to cover the minimum purchases required to sustain a family. The study also found that majority of the working poor in Russia rely on microcredit, short term payday loans and/or traditional bank or credit card borrowing to meet daily necessary expenditure.

Low wages, rising credit

Rosstat data confirms the findings. Roughly 7% of all wage-earners are paid wages below the monthly subsistence minimum. Over 17% of people working in the education sector or various municipal services earn below-subsistence wages.

Moscow has set a target of 2019 for raising wages to the legally required subsistence minimum level, with minimum wages hiked in 2016 and mid-2017. Current minimum wage is set at Rub 7,000 per month (roughly EUR115) which is only about 60% of the average subsistence minimum levels and close to 20% of the average monthly wage, according to BOFIT report. This is about half the level (of 40%) ratio of the minimum wage to the average wage across the OECD countries.

Accumulation of household debt, therefore, is hardly the good news for the economy in the long run, as debt affordability is only sustained today by the falling interest rates (cost of carry), and is not consistent with the wages dynamics, and wages levels, especially at the lower end of earnings.

Meanwhile, the latest data on economic growth came in at a disappointing print. Russian GDP growth fell from 2.5% y/y in 2Q 2017 to 1.8% in 3Q 2016, driven down by slower expansion in both exports and domestic investment. Over the period from January through September, Russian economy grew by roughly 1.6% y/y - well below the official forecasts and analysts consensus expectations. Oil output fell, despite the rise in global oil prices, as Russia continued to implement OPEC-agreed production cuts.

On external trade, exports of oil and related products were up in 3Q 2017 in line with oil prices, rising 26% y/y. Exports of metals and other primary materials were down sharply. In January-September, exports of goods were also up 26% y/y with the share of oil and gas in total goods exports up sharply to 60%.

Notably, the value of exports of goods and services (at USD250 billion) over the first nine months of 2017 has robustly exceeded the value of imports (at USD 170 billion).

Structural Problems

Russian growth slowdown is structural, as I wrote on numerous occasions before. The structural nature of the slowdown is reflected in subdued private investment growth and lack of dynamism in all private enterprise-led sectors, with exception, perhaps of the cyclical agriculture. Even food production sector - which should have benefited from record crops (over 2014-2017) and trade sanctions (import substitution) is lagging. Capital deepening and technological innovation are far behind where these should have been after roughly 19 years of post-default recovery in the economy.

The structural decline in the private sectors activities is contrasted by expansion of the state sector.

According to the Rosstat figures, over recent years some 11-12% of total earnings in the Russian economy was generated by the larger state-owned or part-state-owned enterprises. This figure excludes direct Government spending. In other words, state spending and state-owned companies revenues now account for close to 40% of the Russian GDP. As reported by BOFIT, state-owned enterprises “revenues are highly concentrated. Surveys by the Russian Presidential Academy of National Economy and Public Administration (RANEPA) show that just 54 large state-owned enterprises (SOEs) account for 8% of revenues [half of that accrues to only two companies: Gazprom and Rosneft]. When 20 indirectly state-owned firms are added the share rises to 12%.” This is in line with the figure of 11% reported by Expert.ru based on their list of 400 biggest companies in Russia.

Outright direct Government (local, regional and federal) expenditure amounts to slightly above 13% of GDP, based on Rosstat figures. This means that, raising the larger enterprises share to account for smaller and medium sized state-owned companies, the total state-owned enterprises and Government share of the economy can be around 38% mark, slightly above the 2010 estimate of 35%, provided by the ENRD. Interestingly, the above imbalances in the structure of the Russian economy do not seem to reflect too poorly on the country rankings in the World Bank Doing Business report. Out last week, the rankings put Russia in 35th place globally, our of 190 countries, placing it just below Japan and well ahead of China (78th).

In summary, Russian economy will not be able to get onto a higher growth path (from the current 1-1.5 percent range) until there is a significant shift in growth drivers toward capital deepening (necessary both to offset adverse demographics and the chronic under-investment in new capital over the recent years), and technological deepening (required to modernise industrial and services sectors). To effectively trigger these processes, Russia needs to hit, simultaneously. three policy targets:

  1. Improve overall relationship with Europe, while continuing to build on positive trade and investment momentum with Asia-Pacific region;
  2. Increase the share of private enterprise activity in the economy, by reducing the state share of the economy to below 35% of GDP; and
  3. Focus on reforming institutional frameworks that currently hold Russian investors from investing in the domestic production, including closing gaps on product/services certification between Russia and Europe, and effectively (not pro-forma) reforming legal frameworks.

20/11/17: Wait till rates normalization hits the property markets


In the context of the ongoing Chinese debt bubble crisis (yet to explode into a full crisis, but the timer is ticking ominously), the ZeroHedge presented the following chart:


The dire state of the global economy post-QE waves of 2008-2017 is reflected in the vast asset bubbles building up across the main markets, with Canada, China, Australia leading the surge, while the U.S. residential property prices are now also at historical peak (previous peak reading was at 184.62 against current at 195.05):

New Zealand is not far off from its neighbour, Australia:

Source: https://fred.stlouisfed.org/series/QNZN628BIS.

In short, things are getting beyond the pre-2007 bubble levels and the risks of a blowout in global property markets are rising. All we need is a catalyst for breach, which is likely to be either a ramp up in credit costs in the advanced economies or a tightening of credit in China, or both.

19/11/17: Mainstream Media & Fake News: Twin Forces Behind Voter Behavior Biases


Behavioral biases come in all shapes and forms. Many of these, however, relate to the issue of imperfect information (e.g. asymmetric information, instances of costly information gathering and processing that can distort decision-making, incomplete information, etc).

A recent Quartz article on the balance of threats/risks arising from the 'fake news' phenomenon (the distortion of facts presented, sometimes, by alternative and mainstream media alike) and another informational asymmetry, namely selectivity biases (which apply to our propensity to select information either due to its proximity to us - e.g. referencing bias, or due to its ideological value to us - e.g. confirmation bias, etc). Note: Quartz article is available here: https://qz.com/1130094/todays-biggest-threat-to-democracy-isnt-fake-news-its-selective-facts/.

According to the article: "News sources aim to cover—in the words of the editor in chief of Reuters—the “facts [we] need to make good decisions.”" But, "As readers, we also suffer from what’s called confirmation bias: We tend to seek out news organizations and social media posts that confirm our views. Selective facts occur precisely for this reason." In other words, confirmation bias is a part of our use and understanding of information. The author concludes that "Selective facts are worse than outright fake news because they’re pervasive and harder to question than clearly false statements."

So far so good. except for one thing. The article does not go in detail into why selective facts are, all of a sudden, prevalent in today's world. Why does confirmation bias (and, unmentioned by the author, proximity heuristic) matter today more than they mattered yesterday?

The answer to this, at least in part, has to be the continued polarization of the mainstream media (and, following it, non-traditional media).

Here is a PewResearch study from 2014 on ideological polarization in the mainstream media and social media: http://www.journalism.org/2014/10/21/political-polarization-media-habits/.  Two charts from this:


Not enough to drive home the point? Ok, here is from Forbes article covering the topic (source: https://www.forbes.com/sites/brettedkins/2017/06/27/u-s-media-among-most-polarized-in-the-world-study-finds/#1ee9a3242546):
"The Reuters Institute recently released its 2017 Digital News Report, analyzing surveys from 70,000 people across 36 countries and providing a comprehensive comparative analysis of modern news consumption. The report reveals several important media trends, including rising polarization in the United States. While 51% of left-leaning Americans trust the news, only 20% of conservatives say the same. Right-leaning Americans are far more likely to say they avoid the news because “I can’t rely on news to be true.""

The trend is not new. In the 1990s, plenty of research have shown that print and cable media have started drifting (polarizing) away from the 'centre-focused' news reporting as local monopolies of newspapers and TV stations started to experience challenges from competitors. You can read about this here:

  • Tuning Out or Tuning Elsewhere? Partisanship, Polarization, and Media Migration from 1998 to 2006 by Barry A. Hollander (2008), Journalism & Mass Communication Quarterly, Volume 85, Issue 1, which posits a view that polarization of the mass media has been driving moderate voters away from news and toward entertainment. Which, of course, effectively hollows out the 'centre' of media ideological spectrum. 
  • "This article examines if the emergence of more partisan media has contributed to political polarization and led Americans to support more partisan policies and candidates," according to "Media and Political Polarization" published in Annual Review of Political Science Vol. 16:101-127 (May 2013) by Markus Prior.
  • And economics of media polarization in "Political polarization and the electoral effects of media bias" by Dan Bernhardt, Stefan Krasa, and Mattias Polborn, published in Journal of Public Economics, Volume 92, Issues 5–6, June 2008, Pages 1092-1104
These are just three examples, but there are plenty more (hundreds, in fact) of research papers looking into twin, causally interlinked, effects of media polarization and the rise of the polarized voter preferences.

Which brings us to the Quartz's observation: "While social media and partisan news has allowed more voices to be heard, it also means we are now surrounded by more people manipulating what facts make it to our newsfeeds. We’d draw a different conclusion—or even just a more nuanced picture—if we were given all the information on an issue, not just the parts that best benefit a particular viewpoint."

It may be true, indeed, that current markets for supply of alt-news are enabling greater confirmation bias prevalence in voter attitudes. But it is at best just a fraction of the complete diagnosis. In fact, the polarized, or put differently - biased, nature of the mainstream news is at least as responsible for the evolution of these biases, as it is responsible for the growth in alt-news. That is correct: fake information is finding are more accepting audiences today, in part, because the CNN and FoxNews have decided to cultivate ideologically polarized market differentiation for their platforms in the past.

Sweden, the tough-fighting 'socialist' haven of capitalism is cutting its corporate tax rates. Again.

Yes, that is right. Sweden used to have a decisively 'socialist' rate of corporate income tax (irony implied) of 28% until 2008. In 2009 this rate dropped to a relatively convincing 'socialist' rate of 26.3%, before falling to a sort-of-'socialist' softy 22%. It now plans a cut to 20%.
 h/t for the chart to @mattyglesias 

The announcement is made here: http://www.ey.com/gl/en/services/tax/international-tax/alert--sweden-proposes-major-corporate-income-tax-changes h/t to @tylercowen for the link. 

Note, extensive compliance changes proposed for Swedish tax code to bring it in line with the OECD's BEPS scheme. The scheme was designed, as defined by its objectives, to make it harder for the corporations to avoid taxes in the future. Which means, of course, that to maintain effective tax rates closer to where they were before the BEPS, Sweden, as other states, will need to offset BEPS-induced accounting changes with lower headline rates. 

Tax optimization, folks, just went mainstream in Europe and the U.S. Which is a good thing for transparency (reducing the disparity between the effective rates and the headline rates). But a bad news for personal income taxes. To offset the declines in corporate tax revenues that BEPS changes will inevitably engender, Governments from Sweden to Italy, from Canada to the U.S. will have to either cut spending or increase personal income tax rates. No medals for guessing what they will opt for.

18/11/17: North Korean Uncertainty and Market Impacts


S&P new post about the risks poised by North Korea is a neat summary of key actions and players involved (see the full note: https://marketintelligence.spglobal.com/blog/global-credit-risk-spikes-as-key-apac-countries-respond-to-the-north-korean-threat).

And it is very interesting to those of us, who study the links between geopolitical risks and financial markets.

Two pieces of evidence are presented in the S&P note worth pondering: first, the rising frequency of the North Korea threat signals:


The above shows that starting with 2016, acceleration in the North Korea threat signals has been posing a departure from the previous trend. Structurally, this suggests that we are entering a new regime in terms of potential market spillovers from North Korean risks to global financial markets.

Next, some evidence on changes in specific shares valuations timed close to the North Korean threat signals:

The evidence above suggests that, in line with our research findings in other instances, the uncertainty about North Korean threat evolution is feeding into the valuations of defence stocks. And that this effect is still ambiguous. Which is in line with our findings on the links between actual conflicts and defence stocks valuations revealed in my paper with Mulhair, Andrew, "Performance Analysis of U.S. Defense Stocks in Relation to Federal Budgets and Military Conflicts in the Post-Cold War Era" (April 2017). Available at SSRN: https://ssrn.com/abstract=2975368. Furthermore, the nature of North Korean policy-induced uncertainty is consistent with our findings relating to terrorism spillovers to financial markets as revealed in my paper with Corbet, Shaen and Meegan, Andrew, "Long-Term Stock Market Volatility and the Influence of Terrorist Attacks in Europe" (August 2017). Available at SSRN: https://ssrn.com/abstract=3033951. Note, the latter paper is now forthcoming in the Quarterly Review of Economics and Finance.

While explicit testing of spillovers from North Korean uncertainty to global financial markets is yet to be firmly established in empirical literature, it is worth noting that the indirect evidence (based on data similar to S&P blog post) suggests that North Korean threat is likely to have a significant VUCA-consistent effect on the markets.

18/11/17: ECB Induces Double Error in the EU Policy Markets


In economics, two key market asymmetries/biases lead to the severe reduction in markets efficiency often marking the departure from theoretical levels of efficiency (speed, with which markets incorporate new relevant information into pricing decisions of markets agents) and the practical outcomes. These asymmetries or biases are: information asymmetry and agency problem.

For those, uninitiated into econospeak, information asymmetry (sometimes referred to as information failure), is a situation, in which one party to an economic transaction possesses greater knowledge of facts, material or relevant to the decision, than the other party. For example, a seller may know hidden information about a car on offer that is not revealed to the buyer. In more extreme example, a seller might actively conceal such information from a buyer. This can happen when a seller 'prepares' the car for sale by cleaning the engine, thus removing leaks and accumulations of oil and / or coolant that can indicate the areas where the problems might be.

The agency problem, also referred to as principal-agent problem, arises when an agent, acting on behalf of the principal, has distinct set of incentives from the principal. The resulting risk is that the agent will act in self-interest to undermine the goals and objectives of the principal. An example here would be a real estate agent contracted by the seller, while taking a commission kickback from the buyer. Or vice versa.

Occasionally, both problems combine to produce an even more powerful distortionary result, pushing the markets further away from finding a 'true' (or fundamentals-justified) price point.

Today, we have an example of such interaction. As reported in Euractiv, the ECB has denied the EU Court of Auditors access to data on Greek bailout. (Full story here: http://www.euractiv.com/section/all/news/ecb-denies-eu-auditors-access-to-information-on-greek-bailouts/) The claimed justification: banking secrecy. The result:

  1. There is now clearly an asymmetry in information between the EU, the Court of Auditors, and the ECB when it comes to assessing the ECB actions in the Greek bailout(s). The 'car salesman' (the ECB) has scrubbed out information about the 'vehicle' (the bailout(s)) when presenting it to the 'buyer' and is refusing to show any evidence on pre-scrubbed 'car'.
  2. And there is an agency problem. The ECB is an agent for the EU (and thus an agent relative to the principal - the EU Court of Auditors, which represents the interest of the EU). As an agent, the ECB has a contractual obligation to act in the interest of the EU. But as a part of the Troika in the case of the Greek bailout(s), the ECB is also contracted into a set of incentives to act in concert with other players: the sub-set of the EU, namely the EU Commission and the EFSF/ESM funds, and the IMF. At least one of these agents, the IMF, has a strong incentives to avoid transparent discovery of information about the Greek bailout(s) because these bailout(s) have, potentially, violated the IMF by-laws in lending to distressed countries. Another agent, the EU Commission, has an incentive to conceal the truth about the same bailout(s) in order to sustain a claim that the Greek bailout(s) are(were) a success. The third set of the agents (various EU funds that backed the bailout(s)) has incentives to sustain the pretence that the Greek bailout(s) were within the funds' bylaws and did not constitute state aid to the insolvent government.
In simple terms, the ECB refusal to release information on Greek bailout(s) to the EU Court of Auditors is a fundamental violation of the entire concept of the common market principle that overrides any other consideration, including the consideration of monetary policy independence. This so because the action of the ECB induces two most basic, most fundamental failures into the market: the agency problem and the asymmetric information problem, which are (even when taken independently from each other) the core drivers for market failures.

7/11/17: 800 years of bond markets cycles


An interesting new working Paper from the BofE, titled “Eight centuries of the risk-free rate: bond market reversals from the Venetians to the ‘VaR shock’” (Bank of England, Staff Working Paper No. 686, October 2017) by Paul Schmelzing looks at new data for “the annual risk-free rate in both nominal  nd real terms going back to the 13th century.”

Such a long horizon allows the author to establish and define the existence of the long term “bond bull market”

Specifically, the author shows “that the global risk-free rate in July 2016 reached its lowest nominal level ever recorded. The current bond bull market in US Treasuries which originated in 1981 is currently the third longest on record, and the second most intense.”


And plotting real debt bull markets (shaded):



Finally, the extent of the current bond bull market (since 1981) relative to previous historical bull markets is reflected also in the extent of yield compression (annualized) that has been achieved during each bull market cycle:


While the rest of the paper goes through three specific case studies of bull markets corrections, it is the first section - the one based on historical long-term data series - that poses the starkest evidence of just how exceptional (and thus risk-loaded) the current markets environment is. Looking at historic averages, and potential for historical mean reversion for yields, the current yield on U.S. 10 year paper will have to double, effectively increasing long-term risk exposure to widening fiscal deficits by the tune of 2.5-2.75 percent of GDP. The cost of carrying this level of indebtedness, when yields run 1.5-1.7 times the upper envelope of the potential rate of economic growth is a function of simple arithmetic. Currently, this arithmetic suggests that the U.S. will either have to figure out how to live with above 5% annual deficits and ballooning debt, or how to live within its own means.

7/11/17: To Fine Gael or not: Employment Stats and Labour Force


Recently, Fine Gael party PR machine promoted as a core economic policy achievement since 2011 election the dramatic reduction in Ireland’s unemployment rate. And in fact, they are correct to both, highlight the strong performance of the Irish economy in this area and take (some) credit for it. The FG-led governments of the recent years have been quite positive in terms of their policies supporting (or at least not hampering) jobs creation by the MNCs. Of course, they deserve no accolades for jobs creation by the SMEs (which were effectively turned into cash cows for local and central governments in the absence of any government power over taxing MNCs), nor do they deserve any credit for the significant help in creating MNCs’ jobs that Ireland got from abroad.

Now, to briefly explain what I mean by it: several key external factors helped stimulate MNCs-led new jobs creation in Ireland. Let me name a few.


  1. ECB. By unleashing a massive QE campaign, Mario Draghi effectively underwritten solvency of the Irish State overnight. Which means that Dublin could continue avoiding collecting taxes due from the MNCs. And better, Mr Draghi’s policies also created a massive carry trade pipeline for MNCs converting earnings into corporate debt in Euro area markets. The combined effect of the QE has been a boom in ‘investment’ into Ireland, and with it, a boom of jobs.
  2. OECD. That’s right, by initiating the BEPS corporation tax reform process, the arch-nemesis of Irish tax optimisers turned out to be their arch blesser. OECD devised a system of taxation that at least partially, and at least in theory, assesses tax burdens due on individual corporations in relation physical tangible activities these corporations carry out in each OECD country. Tangible physical activity can involve physical capital investment (hence U.S. MNCs rapidly swallowing up new and old buildings in Ireland, that’s right - a new tax offset), an intangible Intellectual Property ‘capital’ (yep, all hail the Glorious Knowledge Development Box), and… err… employment (that is why Facebook et al are rushing to shift more young Spaniards and Portuguese, French and Dutch, Ukrainians and Italians, Poles and Swedes… into Dublin, despite the fact they have no where to live in the city).
  3. EU. Not to be outdone by the aforementioned ‘academics’ from Parisian La Defence, the EU Commission helped. It waved in the utterly ridiculous, non-transparent, skin deep in fundamentals, Irish tax optimisation scheme that replaced the notorious Double-Irish Sandwich  - the scheme is the already mentioned above Knowledge Development Box. The EU Commission also aggressively pursued a handful of top MNCs trading from Ireland - Apple, Google, etc. This put more pressure on both the Irish Government and the MNCs to cough up some at least half-credible scheme that would show some sort of tangible business expansion and growth in Ireland.

So the result of all of the above has been a jobs boom in the MNCs-dominated sectors, a boom that soaked up quite a bit of the younger graduates from Irish Universities as well, but also helped to grow indigenous ICT sector in Ireland. The latter soaked up some more graduates. Unemployment fell. employment rose.

If this sounds like Nirvana, it ain’t. Because above the silver lining of the good and strong employment/unemployment numbers there is also a cloud of rather darker hues. That club is the Labour Force Participation Rate.


As Chart above shows, seasonally-adjusted LFP for Ireland stood at 59.8% in 2Q 2017 - matching the lowest recorded levels for the entire 16 years since the end of !Q 2001. And the lowest level in 13 consecutive quarters. Worse, as the chart above clearly shows, the dismal performance of the economy in terms of LFP has been in place since the Great Recession. In other words, all the recovery to-date has not been able to shift Irish participation rate.

Which brings us to the real point of the crisis: the current levels of LFP are much much worse than the comparable headline rates attained in 1999-2000. How? Simple.

  • Unlike in 2000-2001, we have years of net outward emigration (and continued net outward emigration for Irish nationals). This should increase LFP, and yet it clearly does not.
  • Unlike in 2000-2001, we have widening retirement age, not shrinking as was the case in 2000-2001. This too should have supported LFP to the upside. And again, it clearly is not happening.
  • In contrast with the 2000-2001, we also have more students in the third level and above education today. Which, again, should have supported current LFP to the upside relative to the early 2000s. 

And so on… in simple terms, our starting conditions (post-crisis environment) and our demographics all suggest that current LFP is reflective of deeper structural problem than the same LFP reading back in 2000-2001 was.

So, yes, Fine Gael can claim some strong record of improvements in the economy that took place on its watch. But, no, this is not the time to enjoy the laurels. Until such time when more Irish people go back to search for jobs, train for jobs and the LFP rises to 63.2% range (2005-2008 average), it is way too early for us to declare a victory over the Great Recession.

Now, what does 3.4% increase in LFP mean? To keep current rate of unemployment fixed at 6%, that means adding 70,450 new jobs and adding roughly 4,500 new unemployed to the Live Register. What that would take in terms of time? Given the current rate of 17,150 new employment added per quarter over the last 4 quarters, this implies about roughly 13 months of jobs creation.

Of course, attracting the disillusioned folks back into labour force is not as easy. So the more important bit is not whether we can achieve it, but rather, what would it mean in terms of economic policies necessary to achieve it? I expect answers from the various FG departments and may be even some Ministers…

28/10/17: Trade vs Growth or Trade & Growth?


Much has been written down recently about the dramatic slowdown in growth in global trade flows. For example, after rebounding post-Global Financial Crisis (global trade volumes fell 10.46% in 2009) in 2010-2011 (rising 12.52% and 7.1% respectively), trade volumes growth slowed to below 4% per annum in 2012-2016, with 2017 now projected to be the first year of above 4% growth in trade (4.16%).

This has prompted many analysts and academics to define the current recovery as being, effectively, trade-less growth (see, for example https://www.bis.org/review/r161125c.pdf).

This is plainly false. In fact, growth in global trade volumes has outpaced growth in real GDP (based on market exchange rates) in every year since 2010, except for 2016. As the chart below clearly shows, the difference between the rate of trade volumes growth and the rate of real GDP growth remained positive in average terms:


Instead, what really happened to the two series that both real GDP growth and trade volumes growth have fallen significantly since 2011. Average growth in trade over 1980-2017 period stood 2.31 percentage points above growth in real GDP. The 2010-2017 period average gap between the two is 1.78 percentage points, the second lowest decade average after 1.48 percentage points gap recorded in the 1980s. However, these comparatives are somewhat distorted by influential outliers - years when post-recessions recoveries triggered significantly higher spikes in growth in both series, and years when trade recessions were substantially sharper than GDP growth slowdowns. Omitting these periods from decades averages, as the chart above illustrates, makes the current recovery (2010-2017 period) look much much worse than any previous decade on the record (green dashed lines).

Still, the above presents no evidence that trade weaknesses contrasted GDP growth trends. And there is no such evidence when we look at decades-based correlations between trade growth rates and GDP growth rates:

In fact, correlation between trade growth and GDP growth is currently (2010-2017 period) running at an extremely high levels of 96%, compared to historical correlation (1980-2017) of 87% and compared to pre-2010 average (1980-2009) of 88%.

So what has been happening, thus?

As the chart above clearly shows, there are significant differences in trends between the two series. Using indexing approach, setting 1979 = 100, we can compute index of real GDP activity and trade volumes activity based on annual rates of growth. The two series exhibit a diverging pattern, with divergence starting around the end of the 1980s, accelerating rapidly during 1993-2008 period and then de-accelerating since the onset of the post-GFC recovery. Notably, however, this de-acceleration simply slowed the expansion of the gap between the two series, and it did not reverse it or close it.

Currently, global GDP growth is just above the long-term trend. But global trade growth has been running below its historical trade since 2014. Back in 2004-2008 period, rate of growth in global trade vastly exceeded its trend. Why? Because 2004-2008 period was the period of rapidly inflating real assets bubbles around the globe - the period of ample credit and ample demand for investment goods and raw materials. Similar logic applies to 1994-2000 period of  In other words, the glorious days of global trade expansion, the period of accelerated growth in trade.

In other words, past periods of exploding trade volumes growth are unlikely to reflect sustainable trends in the real economy. These were the periods of substantial misalignment between trade and growth much more than the current period of slower trade growth suggests. In other words, something is happening to both trade and growth, and that, most likely, is what we call a structural slowdown or a secular stagnation.

28/10/17: Supplies of Monetary Methadone: ECB's Recalibration


My take on ECB's latest policy announcements for the Sunday Business Posthttps://www.businesspost.ie/opinion/supplies-monetary-methadone-will-continue-401179.

28/10/17: Income Inequality: Millennials vs Baby Boomers


OECD's recent report, "Preventing Ageing Unequally", has a wealth of data and analysis relating to old-age poverty and demographic dynamics in terms of poverty evolution. One striking chart from the report shows changes in income inequality across two key demographic cohorts: the Baby Boomers (born at the start of the second half of the 20th Century) and the Millennials (born in the last two decades of the 20th Century):


Source: http://www.oecd.org/employment/preventing-ageing-unequally-9789264279087-en.htm.

The differences between two generations, controlling for age, are striking. In my opinion, the dramatic increase in income inequality across two generations in the majority of OECD economies (caveats to Ireland and Greece dynamics, and a major outliers of Switzerland, France and the Netherlands aside) is one of the core drivers for changing perceptions of the legitimacy of the democratic ethics and values when it comes to public perceptions of democracy. 

You can read more on the latter set of issues in our recent paper, here: http://trueeconomics.blogspot.com/2017/09/7917-millennials-support-for-liberal.html.

The dynamics of income inequality for the Millennials do not appear to relate to unemployment, but rather to the job markets outcomes (which seemingly are becoming more polarized between high quality jobs/careers and low quality ones):
In other words, where as in the 1950s it was sufficient to have a job to gain a place on a social progression ladder, today younger workers need to have the job (at Google, or Goldman Sachs, or other 'star' employers) to achieve the same.

Thus, as low unemployment swept across the advanced economies in the post-Global Financial Crisis recovery, there has not been a symmetric amelioration of the youth poverty rates in a number of countries:

In 25 OECD countries out of 35, poverty rates for those aged 18-25 are today higher than for those of age 65-75. Across the OECD, statistically, poverty rates for the 18-25 year olds cohort are on par with those for of 76+ year olds cohort, and both are above 12 percent. 

There is a lot that is still missing in the above comparatives. For example, the above numbers do not adjust for differences between different age groups in terms of quality of health and education. Younger workers are also healthier, as a cohort, than older population groups. This means that their incomes should be expected to be higher than older workers, simply by virtue of better health.  Younger workers are also better educated than their older counterparts, especially if we consider the same age cohorts for current Millennials and the Baby Boomers. Which also implies that their incomes should be higher and their income inequality should be lower than that for the Baby Boomers.

In other words, simple comparatives under-estimate the extent of income inequality and poverty incidence and depth for the Millennials by excluding adjustments for health and education differences.

22/10/17: Italian North: another chip off Europe's Nirvana


Having just written about the Czech electoral pivot toward populism last night, today brings yet another  news headline from the politically-hit Europe.

In a non-binding referendums in two wealthiest Italian regions, Veneto and Lombardia, the voters have given local governments strong mandates to push for greater autonomy from Rome and the Federal Government. Both regions are dominated by the politics of Lega Nord, a conservative, autonomy-minded party with legacy of euro scepticism, strong anti-immigration sentiment and the past promotion of outright independence for the Northern Italy.

In both referendums, turnout was relatively strong by Italian standards (58% projected for Veneto and over 40% for Lombardia). And in both, exit polls suggest that some 95% of voters have opted for stronger regional autonomy.

The referendums were not about outright independence, but about wrestling more controls over fiscal and financial resources from Rome. Both regions are net contributors to the Italian State and are full of long run resentment over the alleged waste of these resources. Both regions want more money to stay local.

In reality, however, the vote is about a combination of factors, namely the EU policies toward Italy, the monetary conditions in the euro area, the long-term stagnation of the Italian economy and the centuries-old failure of Italian Federal State to reform the economy and the society of the Southern Italian regions. Italy today is saddled with stagnation, huge youth unemployment, lack of business dynamism, weak entrepreneurship, dysfunctional financial institutions, high taxes, failing and extremely heterogenous public services, collapsed demographics and centuries-old divisions. Some of these problems are european in nature. But majority are Italian.

Greater autonomy for wealthier regions, in my view, is a part of the solution to the long running problems, because it will create a set of new, stronger incentives for the Southern regions to reform. But in the end, it is hard to imagine the state like Italy sustaining its membership in the euro area without an outright federalization of the EU.

In the nutshell, within a span of few weeks, the dormant political volcano of the Europe has gone from stone cold to erupting. Spain, Austria, Czech, & Italy are in flames. Late-stage lava flows have been pouring across Poland, Hungary and the UK, Slovakia and parts of the Baltics for months and years. Tremors in Belgium, the Netherlands, Germany, (especially Eastern Germany) and Finland, as well as occasional flares of populist/extremist activity in other parts of the Paradise are ongoing. And, it is only a matter of time before populism resurges in France.

All of this with a background of stronger economic growth and booming markets. So wait till the next crisis/recession/market correction hits...

22/10/17: Robot builders future: It's all a game of Go...


This, perhaps, is the most important development in the AI (Artificial Intelligence) to-date: "DeepMind’s new self-taught Go-playing program is making moves that other players describe as “alien” and “from an alternate dimension”", as described in The Atlantic article, published this week (The AI That Has Nothing to Learn From Humans - The Atlantic
https://www.theatlantic.com/technology/archive/2017/10/alphago-zero-the-ai-that-taught-itself-go/543450/?utm_source=atltw).

The importance of the Google DeepMind's AlphaGo Zero AI program is not that it plays Go with frightening level of sophistication. Instead, it true importance is in self-sustaining nature of the program that can learn independently of external information inputs, by simply playing against itself. In other words, Google has finally cracked the self-replicating algorithm.

Yes, there is a 'new thinking' dimension to this as well. Again, quoting from The Atlantic: "A Go enthusiast named Jonathan Hop ...calls the AlphaGo-versus-AlphaGo face-offs “Go from an alternate dimension.” From all accounts, one gets the sense that an alien civilization has dropped a cryptic guidebook in our midst: a manual that’s brilliant—or at least, the parts of it we can understand."

But the real power of AlphaGo Zero version is its autonomous nature.

From the socio-economic perspective, this implies machines that can directly learn complex (extremely complex), non-linear and creative (with shifts of nodes) tasks. This, in turn, opens the AI to the prospect of writing own code, as well as executing tasks that to-date have been thought of as impossible for machines (e.g. combining referential thinking with creative thinking). The idea that coding skills of humans can ever keep up with this progression has now been debunked. Your coding and software engineering degree is not yet obsolete, but your kid's one will be obsolete, and very soon.

Welcome to the AphaHuman Zero, folks.  See yourself here?..

22/10/17: Framing Effects and S&P500 Performance


A great post highlighting the impact of framing on our perception of reality: https://fat-pitch.blogspot.com/2017/10/using-time-scaling-and-inflation-to.html.

Take two charts of the stock market performance over 85 odd years:


The chart on the left shows nominal index reading for S&P500. The one on the right shows the same, adjusted for inflation and using log scale to control for long term duration of the time series. In other words, both charts, effectively, contain the same information, but presented in a different format (frame).

Spot the vast difference in the way we react to these two charts...

22/10/17: Leverage risk and CAPE: Why Rob Shiller Might Be Wrong


Rob Shiller recently waxed lyrical about the fact that - by his own metrics - the markets are overpriced, yet no crash is coming because there is not enough 'leverage in the system' to propagate any shocks to systemic levels.

The indicator Shiller used to define overpricing is his own CAPE - Cyclically Adjusted PE Ratio - and the indicator does indeed flash red:


CAPE is defined by dividing the S&P 500 index by the 10-year moving average of index components' earnings. The long-run average of CAPE is 16, and the index currently sits above 31, making the current markets valuations trailing those of the dot.com bubble peak (using recent/modern comparatives).

So the markets are very expensive. But what Shiller says beyond this mechanical observation is very important. His view is that these levels of valuations are 'sustainable' in the medium term because there is very little leverage used by investors in funding these levels of stock prices. In the nutshell, this says that if there is any major correction in the markets, investors are unlikely to be hit by massive margin calls, triggering panic sell-offs. So any correction will be short-lived and will not trigger a systemic crisis.

All fine with the latter part of the argument, if we only look at the stock market brokerage accounts leverage, ignoring other forms of leverage.  And we can only do this at a peril.

Investor is a household. Even an institutional one, albeit with a stretch. When asset prices correct downward, income received by investors falls (dividends and capital gains are cut) and investor borrowing capacity falls as well (less wealth means lower borrowing capacity). But debt levels remain the same.  Worse, cost of funding debt rises: as banks and other financial intermediaries see their own assets base eroding, they raise the cost of borrowing to replace lost income and capital base with higher earnings from lending. Normally, the Central Banks can lower cost of borrowing in such instances to compensate for increased call on funds. But we are not in a normal world anymore.

Meanwhile, unlike in the dot.com bubble era, investors/households are leveraged not in the investment markets, but in consumption markets. Debt levels carried by investors today are higher than debt levels carried by investors in the dot.com and pre-2007 era. And these debts underwrite basics of consumption and investment: housing, cars, student loans etc (see https://www.bloomberg.com/view/articles/2017-10-18/don-t-rely-on-u-s-consumers-to-power-global-growth). Which means that in an event of any significant shock to the markets, investors' debt carry costs are likely to rise, just as their wealth is likely to fall. This might not trigger a market collapse, but it will push market recovery out.



An added leverage dimension ignored by Shiller is that of the corporates. During the crises, cash-rich and/or liquid corporates can compensate for falling asset prices by repurchasing stocks. But corporates are just now completing an almost decade-long binge in accumulating debt. If the cost of debt carry rises for them too, they will be the unlikely candidates to support re-leveraging necessary to correct for an adverse asset prices shock.

I would agree with Shiller that, given current conditions, timing the markets correction is going to be very hard, even as CAPE indicator continues to flash red. But I disagree with his view that only margin account leverage matters in propagating shocks to a systemic level.
