摘要

Are you a bull or a bear? a tortoise or a hare? Your answer is not as important as how you arrived at it. The investment world's biggest divide these days is between two competing interpretations of reality: the efficient market theory and behavioral finance. The University of Chicago, where I am a trustee, is home to two of the most distinguished champions of these beliefs: Eugene Fama for the efficient market approach and Richard Thaler for the behavioral one. My corporate finance professor, Burton Malkiel, taught me efficient market theory. Efficiency theorists argue that markets are completely rational and stocks priced to reflect all information known to investors. If there's a piece of news about a stock, investors will act promptly and adjust the share price. If the market is efficient, you can't beat it. At least not consistently and over a long span of time. The only exception is small- and mid-cap stocks that are generally less followed.
