Furthermore, when the test is performed using the base observation period of four weeks, the random walk hypothesis cannot be rejected for all ten countries. Thus the findings of this study are inconsistent with those of Lo and MacKinlay (1988) who find the weekly U.S. stock returns do not follow the random walk. Unlike what some academics say, individual and professional investors can in fact time the stock market. Use charts properly, then spot a follow-through. The Random Walk Theory or Random Walk Hypothesis is a financial theory that states the prices of securities in a stock market are random and not influenced by past events. It suggests the price movement of the stocks cannot be predicted on the basis of its past movements or trend.
