Fundamental Analysis And The Efficient Market
Fundamental analysis for stocks reflects the idea that undervalued stocks can be found and invested in to create superior performance. In order for fundamental analysis to work, the market would have to be inefficient. The efficient market hypothesis maintains that all publicly known information is quickly reflected into the price of stocks and therefore markets are efficient. This theory is also referred to as the random walk theory and suggests that a random stock selection is as good as any other method.
The semi-strong form of the efficient market theory uses the concept that enough investors attempt to use the publicly available information to their advantage that it creates a situation where no advantage ends up being available to anyone.
While the existence of asset bubbles, such as the dot com and housing, do not reflect an extremely efficient market, and it is true that some users of fundamental analysis such as Warren Buffet regularly outperform the market, it is also true that the majority of actively managed mutual funds underperform the market(1)(2)(3). The odds do not favor a successful fundamental analysis approach to investing over an efficient market approach.
