Which statement is most consistent with the efficient markets hypothesis?

A) Information in the market is always assessed correctly.
B) Information is reflected in security prices almost immediately.
C) Chartists have an advantage because the market is predictable.
D) Investors cannot consistently earn a positive return on investment over time.

The efficient markets hypothesis suggests that all available information is reflected in security prices almost immediately, so investors cannot consistently earn a positive return on investment over time. This means that choice A is incorrect. Choice C is also incorrect because efficient markets hypothesis suggests that market movements are random and cannot be predicted. Therefore, chartists do not have an advantage.
