Which of the following contradicts the proposition that the stock market is weakly efficient?
a. over 25% of mutual funds outperform the market on average.
b. insiders earn abnormal trading profits.
c. every january, the stock market earns above-normal returns.
d. applications of technical trading rules fail to earn abnormal returns.
