Kaylee Sumners, Level 1 CFA candidate, has just finished reviewing flash cards for the reading on the efficient market hypothesis (EMH). Confused by the different tests for the different forms of the EMH, she outlines the information (of which four summary points appear below) from memory. It appears that Sumners should review the material because three of the points are incorrect. Which of her summary points is CORRECT?

These two tests support the weak-form EMH contention that security prices reflect all historical market information and that mechanical trading rules do not result in superior returns.
The other statements are false.Latertests of the semi-strong form EMH used the equation: ReturnAbnormal= ReturnActual"" (RMarket* BetaStock). Early tests omitted beta, using the formula: ReturnAbnormal= ReturnActual"" RMarket. The superior historical performance of exchange specialists and corporate insiders rejects thestrongform of the EMH. Cross-sectional tests such as the price-earnings ratio, neglected firms tests, and book value to market value testsrejectthe semi-strong form of the EMH. These tests show that certain stocks have high realized returns (for example, low P/E stocks and high book value to market value stocks).
