Efficient Market Hypothesis (EMH) Quiz Questions and Answers

1. What is the Efficient Market Hypothesis (EMH)?

  • A. The theory that financial markets always reflect all available information.
  • B. The belief that markets are inefficient and prone to speculative bubbles.
  • C. The idea that market participants are always rational in their decision-making.
  • D. The notion that government intervention is necessary for market stability.

Correct Answer: A. The theory that financial markets always reflect all available information.

Explanation: According to the Efficient Market Hypothesis, option A is correct because it asserts that financial markets incorporate and reflect all relevant information.

This means that it is difficult to achieve consistent profits by using historical information or analysis as prices already incorporate all available knowledge. Options B, C, and D are incorrect because they do not align with the core concept of EMH.

2. What is the implication of the Weak Form of the Efficient Market Hypothesis?

  • A. Technical analysis can be consistently used to outperform the market.
  • B. All historical price and volume information is already reflected in current stock prices.
  • C. Market participants are always rational in their decision-making.
  • D. Government regulations are needed to control market fluctuations.

Correct Answer: B. All historical price and volume information is already reflected in current stock prices.

Explanation: The Weak Form of EMH suggests that past trading information, such as historical prices and volumes, is already incorporated into current stock prices. Therefore, option B is correct. Options A, C, and D are incorrect as they do not align with the implications of the Weak Form of EMH.
