Suppose that, after conducting an analysis of past stock prices, you come up with the following observations. Which would appear to contradict the weak form of the efficient market hypothesis? Explain.
a. The average rate of return is significantly greater than zero.
b. The correlation between the return during a given week and the return during the following week is zero.
c. One could have made superior returns by buying stock after a 10% rise in price and selling after a 10% fall.
d. One could have made higher-than-average capital gains by holding stocks with low dividend yields.
The correct answer is ‘c’.
A direct implication of the Efficient Market Hypothesis is that consistently beating the market on a risk adjusted basis would be less likely as market prices should react only to the new information.
Since, according to the weak form of Efficient Market Hypothesis, beating of the market by investor is not possible. Hence the correct answer is c
Dollar-cost averaging means that you buy equal dollar amounts of a stock every period, for example, $500 per month. The strategy is based on the idea that when the stock price is low, your fixed monthly purchase will buy more shares, and when the price is high, fewer shares. Averaging over time, you will end up buying more shares when the stock is cheaper and fewer when it is relatively expensive. Therefore, by design, you will exhibit good market timing. Evaluate this strategy.
