答案和详解如下！ Question 86 Which of the following statements about tests of the efficient market hypothesis (EMH) is most accurate? A) The results of statistical and trading rule tests support the weak form of the EMH. B) All three forms of the EMH are supported by the fact that no documented market anomalies have persisted over time. C) The superior historical performance of exchange specialists and corporate insiders is consistent with the strong form of the EMH. D) Cross-sectional tests of market efficiency based on price-earnings ratios, analyst coverage, and book-to-market values generally support the semi-strong form of the EMH.
The correct answer was A) The results of statistical and trading rule tests support the weak form of the EMH. Statistical and trading rule 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. The superior historical performance of exchange specialists and corporate insiders argues against the strong form of the EMH. Cross-sectional tests based on price-earnings ratios, analyst coverage, and book-to-market values offer evidence against the 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). A number of market anomalies have been documented, such as the small-firm and negleced-firm effects and several calendar effects. This question tested from Session 13, Reading 54, LOS b, (Part 2)
