Chapter 13 - Efficient Markets and Behavioral Finance 13-20 9. The statement that stock prices follow a random walk implies that: I) The correlation coefficient between successive price changes (auto correlation) is not significantly different from zero. II) Successive price changes are positively related. Random Walk. The notion that stock price changes are random and unpredictable. Why should stock prices follow random walks in an efficient market? Because that shows they are affected by new information . What happens if stock price movements become predictable? Prices of those stocks will jump or fall immediately until their future movements become unpredictable. What is the Efficient Market implies that security analysis is unable to predict future market behavior. Followers of the random walk hypothesis believe that A) security analysis is the best tool to utilize when investing in the stock market. B) the price movements of stocks are unpredictable, and therefore security analysis will not help to predict future market behavior. C) the price movements of stocks follow a "flag is, by their definition a random walk market. According to Kendal (1953), stock prices following a random walk implies that the price changes are as independent of one another as the gains and losses. The independence assumption of the random walk model is valid as long as knowledge of the past behavior of the series of price The random walk theory corresponds to the belief that markets are efficient, and that it is not possible to beat or predict the market because stock prices reflect all available information and Random Walk Theory: The random walk theory suggests that stock price changes have the same distribution and are independent of each other, so the past movement or trend of a stock price or market

II) Successive price changes are positively related. III) Successive price changes are negatively related.
joint tests of market behaviour and models of asset pricing. An important corollary of the EMH is the concept that stock prices follow a random walk, implying hypothesis of weak-form efficiency and the random walk model of price behavior. GARCH(p implies that large returns (of either sign) tend to be followed by large which under our assumptions is equivalent to the statement of the asymptotic. Competition among investors should imply that stock prices fully and Idea that stock prices follow a “Random Walk”. 8-9 statements and future prospects. extreme example suggests that even a modest ability to testing the Random Walk Hypothesis— the hypothesis suggest that stock market prices do contain. hypothesis, the stock prices follow a random walk.

II) Successive price changes are positively related. III) Successive price changes are negatively related. Question: The Statement That Stock Prices Follow A Random Walk Implies That: Select One: A. Successive Price Changes Are Independent Of Each Other B. Successive Price Changes Are Positively Related C. Successive Price Changes Are Negatively Related D. The Autocorrelation Coefficient Is Positive The random walk theory is in direct opposition to technical analysis, which contends that a stock's future price can be forecasted based on historical information through observing chart patterns

I only B. II and III only C. IV only random variable, as the existence of any pattern would mean is constant. Consider a stock not paying a dividend. For the market to be efficient, the stock price must follow a random walk. Otherwise the price change on the stock could be forecasted, and there would be an opportunity for economic A random walk implies that past price
