Talking Business - Poking Holes in a Theory on Markets - NYTimes.com

You know what the efficient market hypothesis is, don’t you? It’s a theory that grew out of the University of Chicago’s finance department, and long held sway in academic circles, that the stock market can’t be beaten on any consistent basis because all available information is already built into stock prices. The stock market, in other words, is rational.

Good article.
