In the pаper “The Behаviоr оf Stоck-Mаrket Prices,” Fama (1965) claims that stock prices follow a random walk. In contrast, Lo and MacKinlay (1988) demonstrate that “Stock Market Prices Do Not Follow Random Walks….” Fama argues that even if there are dependencies in the process generating stock prices there are “offsetting mechanisms” in the market which tend to produce price changes that follow a random walk. Discuss two possible dependencies and two offsetting mechanisms. [8] Briefly outline the main idea behind the test Lo and MacKinlay used to reject the random walk. [4] Why did Lo and MacKinlay compute both homoscedastic and heteroscedastic standardized test statistics? [3] Lo and MacKinlay faced a trade-off between the use of daily and weekly data, but decided on the latter. What were the issues they faced? [3] Discuss the results from Lo and MacKinlay and the different implications of their findings. [7]
