The correct answer is D

The weak-form EMH assumes the price of a security reflects all currently available historical information. Thus, the past price and volume of trading has no relationship with the future, hence technical analysis is not useful in achieving superior returns.

The other statements are true. The strong-form EMH states that stock prices reflect all types of information: market, non-public market, and private. No group has monopolistic access to relevant information; thus no group can achieve excess returns. For these assumptions to hold, the strong-form assumes perfect markets – information is free and available to all.

The correct answer is B

The weak-form EMH suggests that technical analysis will not provide excess returns while the semi-strong form suggests that fundamental analysis cannot achieve excess returns. The weak-form EMH assumes the price of a security reflects all currently available historical information. Thus, the past price and volume of trading has no relationship with the future, hence technical analysis is not useful in achieving superior returns.

The other choices are correct. The strong-form EMH states that stock prices reflect all types of information: market, non-public market, and private. No group has monopolistic access to relevant information; thus no group can achieve excess returns. For these assumptions to hold, the strong-form assumes perfect markets – information is free and available to all.
