I don’t think that EM stocks have ever been good forecasters of anything

The return of decoupling

Posted by: Felix Salmon
Tags: stocks,

John Authers thinks that since emerging-market bourses have outperformed developed-market indices over the course of this stock-market rally, investors are betting on decoupling:

The underlying trend is clear; rightly or wrongly the market believes that China and the other emerging markets will pull the world through.

I don’t think that’s clear at all. Given the degree to which emerging-market stocks underperformed on the way down, it’s only natural for them to outperform on the way up.

Emerging-market stocks are high-beta assets, and in times of general volatility, as we’ve seen over the past couple of years, they exhibit really high volatility. You need a strong stomach to invest in them, and you’re likely to get whipsawed quite a lot. But as a result, trying to extrapolate a big-picture global macroeconomic forecast from a relatively short-term movement in emerging-market stock indices is a fool’s game. I don’t think that EM stocks have ever been good forecasters of anything; there’s certainly no reason to believe they’re demonstrating something in particular right now."

Me:

“We have heard the emerging markets decoupling story before. But this time there is a difference - the markets really seem to believe it.”

What was it before? An urban legend? Gossip about a couple breaking up? Who’s ‘we’? Shouldn’t he tell us where he heard this story before? And now? Was it one of the attorneys for one of the members of the couple?

“So the market really has faith in decoupling this time. Does it have too much faith?”

Now it sounds more like a creed or a hope.

“Disquieting signs, such as the failure of US financial stocks to make any gain since the stress test results came out a month ago, suggest all is not well.”

Now it’s a failed promise or a bad meal.

“But the underlying trend is clear; rightly or wrongly the market believes that China and the other emerging markets will pull the world through.”

Why isn’t the trend clear? How did we go from “seem” to “believe” in this short post?

I like Authers. I think that he was actually having a bit of fun about decoupling in this post.

“But suddenly, in late October, they hit a bottom and started to rise.”

His point is about how silly this decoupling talk sounds. Namely,it has a portentous quality unjustified by the facts. Of course, I thought that “The Homecoming” was a comedy.

economists have no robust system of determining which statements about economics are true, and which are not

The Sorry State Of The Dismal Science

John Authers' recent interview with University of Chicago professor Richard Thaler is a fine example of what I hope are broader trends in economic thought. To some, it might seem like just another interview. But Authers undoubtedly recognizes its significance. Thaler is a professor at the University of Chicago, which is the birth place of the Efficient Market Hypothesis, and Authers is a well-respected columnist for the Financial Times, which is arguably the voice of the free market in the press. And yet, there they are, casting doubt upon the very theories underpinning a generation of thought that have made the University of Chicago the epicenter of free market ideology. In the language of soda-pop-economics, this interview is a "black swan."

It seems Authers is leaning ever closer towards a world view informed by behavioral economics. While I haven't done any empirical research into Authers' work, I do read his column, The Short View, religiously (personally, I recommend you do the same). And as the recent downturn developed, I noticed several articles that suggest he's come to question at least some of the assumptions underlying the old free market dogmas, particularly the Efficient Market Hypothesis. In my opinion, this is a welcomed development. And I sincerely hope it is part of a broader trend away from grandiose theories about how humans make decisions and towards precise theories which are supported by real-world observations.

Those that have toiled through my writing in the past know that I am a big fan of free markets. Yet, I am not a big fan of the EMH. And in general, I find a lot of economic theory, particularly macroeconomic theory, to be little more than hand-waving. There's an almost priestly air about it that makes me deeply suspicious of its validity. In gentler terms, Economics lacks a rigorous epistemological theory. That is, economists have no robust system of determining which statements about economics are true, and which are not. This is in stark contrast to say, mathematics. A statement about an alleged mathematical truth is verifiable (putting Gödel and Turing aside for the moment). If you tell me that you have discovered a new mathematical truth, you can sit down and in a finite number of words, provide a logical path from assumptions we both agree are true to your new found conclusions that I must accept as true, else I reject either the assumptions or logic itself. Now, I understand that economics can never be a purely deductive sport, since it is complicated by the nuance and uncertainty of, well, reality. But that doesn't mean we can't do better than simply assuming away all of human ridiculousness.

The economics that assumes rational behavior on the part of humanity is, in my opinion, dead. It is simply at odds with everyday experience. It's arguable that the desire for wealth is itself an inherently irrational impulse for most of the developed world, given that our needs would likely be satisfied on public assistance. That said, those who are able to control their behavior and act rationally do a much better job at generating and accumulating wealth. But once they get the money, they go and do something absurd with it, like buy a fleet of planes. So while reason and deferred consumption might be the means by which we accumulate wealth, the end goal of accumulating wealth seems to be driven by a need to express dominance, or at least an antisocial impulse to be free of society's constraints. This view finds support in popular culture, which often equates wealth with conspicuous consumption, sexuality, and control. All of this suggests that somewhere buried under all of those pinstripes is a real brute.

If I am correct, and there is a sea change taking place in how economists view human behavior and the markets humans create, then there may be a lot of quackery in the short term. That is, during the intellectual power vacuum that will follow the demise of the old Chicago School, a few crackpots might temporarily seize power as we trace our way from the four humors to phlogiston. But when we finally get our Lavoisier, this time let's remember to keep his head on, despite our penchant for the irrational."

Does the Fed know something about banks that we don’t?

Short View: Fed’s shock and awe

By John Authers, Investment editor

The Federal Reserve is on a war footing and it is using the Powell doctrine – only go to war as a last resort, and do so with overwhelming force.

The stunning news that it would buy $300bn (€222bn) in Treasury bonds (and spend a lot more on many other fixed-interest securities) also used another classic military strategy. It had the element of surprise.

Even after the central banks of Japan, Switzerland and the UK bought bonds and successfully pushed down interest rates (“quantitative easing“), and even though the Fed said three months ago that it might buy bonds, nobody expected such a drastic move. Fed officials had downplayed it in recent days.

It provoked a drastic market response. Ten-year Treasury yields dropped half a percentage point in minutes. The dollar dropped more than 3 per cent against the euro, its biggest daily fall in many years, and the S&P 500 briefly surged above 800, having hit 666 less than two weeks ago.

The Fed had cover from this week’s inflation data if it did not want to go through with the purchases. Both producer and consumer prices are rising a bit faster than had been thought, providing an argument that drastic rate cuts to fight deflation were not necessary.

Sentiment appeared better. The stock rally came amid stories that banks were making money, and that the term asset-backed securities loan facility (Talf) might revive credit, while 10-year yields, at around 3 per cent, were still historically low.

So why did the Fed do it? The theories are out there. With the AIG bonuses moving public opinion against bail-outs, this may be the only way to pump more public money into credit. Congress will not approve such a thing. Or the Fed may know something about the banking system that others do not.

But for now, the tactic of shock and awe rules.
