efficient market hypothesis In finance, the efficient-market hypothesis (EMH) asserts that financial markets are “informationally efficient”, or that prices on traded assets (e.g., stocks, bonds, or property) already reflect all known information, and instantly change to reflect new information. Therefore, according to theory, it is impossible to consistently outperform the market by using any information that the market already knows, except through luck. Information or news in the EMH is defined as anything that may affect prices that is unknowable in the present and thus appears randomly in the future. The hypothesis has been attacked lately by critics who blame belief in rational markets for much of the current financial crisis, with noted financial journalist Roger Lowenstein recently declaring “The upside of the current Great Recession is that it could drive a stake through the heart of the academic nostrum known as the efficient-market hypothesis.” (Wikipedia Jan 2010)

Unfortunately, instead of a ‘game-changing’ confidence-inspiring reform, the Obama administration presented the United States with the Dodd-Frank Act — a legislative miscarriage that has the potential to hold back recovery and impair the position of New York as a world financial center for decades — unless repealed or drastically amended.

Markets can be inefficient for different reasons and persist for long periods. The transition between one type of inefficient market to the next is usually a period of strife and uncertainty which may last five to fifteen years. Looking back at how the economy emerged from previous transitions, I note that in each new period, equity prices started at reasonable levels. This was true at the beginning of the Roaring Twenties, the Post WW II Period, and the Reagan Era. It is as if markets, recognizing prior inefficiencies ‘reset’ and start over. However, for the current market to ‘reset’, it will be necessary for equity prices to fall considerably, which will have dire consequences.

Eventually, at some point, without an efficient market, common stocks become mere baseball cards.
Sooner or later, some Baby Boomer, pressed to pay his bills in retirement, will find that one can’t live off the dividends of common stock and that when everyone is trying to cash out their holdings at the same time, market prices plunge to levels that seemed inconceivable for generations. But it will simply be the cost of allowing an inefficient market to flourish for so long.
This article discusses the concept of inefficient markets and the practical consequences.
