If the market is weak form efficient:

Question

Quizplus · Accepted Answer

If the market is weak form efficient, it means that all historical price and volume information is already reflected in the current market price. This doesn't necessarily mean that all other information, such as publicly available information or insider information, is equally reflected in the current market price. Therefore, semistrong form efficiency may still hold if the market is weak form efficient, but strong form efficiency does not necessarily have to hold.
