Which of the following would provide evidence against the semistrong form of the efficient market theory?

A)
Low P/E stocks tend to have positive abnormal returns over the long run.

B)
Trend analysis is worthless in determining stock prices.

C)
All investors have learned to exploit signals related to future performance.

P/E information is publicly available information and therefore this test relates to the semistrong-form EMH. Trend analysis is based on historical information and therefore relates to the weak-form EMH. In an efficient market one would expect 50% of pension fund managers to do better than average and 50% of pension fund managers to do worse than average. If all investors exploit the same information no excess returns are possible.
