This Is Not Rothschild's Market

It might seem crazy what I’m ’bout to say

Sunshine she’s here, you can take a break

I’m a hot air balloon that could go to space

With the air, like I don’t care baby by the way

Cliff Asness and John Liew have an article that is in the latest issue of Institutional Investor , discussing the development, strengths, and shortfalls of the Efficient Market Hypothesis, which underlies the Nobel award for both Fama (as a proponent) and Shiller (as a skeptic) this year. One of the interesting points that Asness and Liew make is that examinations of market efficiency depend on the “joint hypothesis” that (a) prices move efficiently to represent correct values, and (b) the model of values that they move to is correct. They point out that if prices seem to deviate from fair value (as expressed by a model), that could mean that either markets are inefficient/irrational, or that the model is wrong (or both). And they suggest strengthening the EMH to include a limitation on such models that they make some kind of sense – since a model that incorporates irrational behavior might well-describe all sorts of crazy market action but not be “efficient” in any sense that makes sense to us.

This may not be an irrelevant reflection, given the price events yesterday. Stocks more than rebounded from yesterday’s Ukraine-induced selloff, implying that not only are stocks just as valuable yesterday as they were Monday, but that they are even more valuable than they were before we found out about escalating tensions in the Crimean. This seems to border on the “unusual model” side of things – especially since nothing particularly soothing happened yesterday.

Earlier yesterday, Reuters reported that one of the Russian threats made in response to the vague declarations of the U.S. that “all options are on the table, from diplomatic to economic” (pointedly leaving out “military,” as Obama did Monday, because gosh knows we don’t want the Russians to think that’s even a possibility) was that Russians might not repay loans due to U.S. banks (or, presumably, European banks if they joined any sanctions). This is a clever threat, in the old vein of “if you owe $100, it’s your problem; if you owe $1 billion, it’s the bank’s problem.” Everyone who thinks that economic sanctions are a no-brainer are correct, in the sense that it would imply no brain.

Russia also tested an intercontinental ballistic missile . This was “viewed as non-threatening and is not connected to what is going on in Crimea,” which is of course absurd: regardless of how long the test has been scheduled, someone who was trying to “de-escalate” tensions would surely defer the test for a week. The fact that the test happened is one of many signs that Putin’s soothing words yesterday were hollow. All of the actions yesterday, from additional warships steaming towards the Crimean peninsula to ICBM launches and confrontations between Ukrainian and Russian troops, were consistent with an escalating crisis even as Putin said there was no “immediate” need to invade eastern Ukraine.

Stocks loved the idea that the conflict may be over, with the west simply conceding the Crimea and Russia deciding that she is sated for the time being, as ridiculously unlikely as that outcome actually is. And, as I fully expected, we heard over and over yesterday the Rothschildian admonition to “buy on the sound of cannons.” And indeed, they bought. Oh, how they bought. The S&P rose 1.53% and most European bourses were up 2%-3%. The expected comparisons were made, to the performance of equities during and following the Cuban Missile Crisis, the first Gulf War, and the invasion of the Sudetenland.

These comparisons are all nonsense. Here’s why:
