Market Efficiency

What is the Efficient Market Hypothesis (EMH) and what are its three forms?

• The Efficient Market Hypothesis (EMH) is a theory that states that asset prices are determined solely by government regulations.

• The Efficient Market Hypothesis (EMH) is a theory that states that asset prices fully reflect all available information. It comes in three forms: weak form, semi-strong form, and strong form.

• The Efficient Market Hypothesis (EMH) is a theory that states that asset prices reflect only historical data.

Explain the concept of Informational Efficiency using the example of a stock market where all publicly available information is quickly reflected in stock prices, making it challenging for investors to consistently outperform the market.

• Informational Efficiency suggests that investors should rely on insider information for success

• Informational Efficiency is the concept that market prices reflect all available information, making it difficult for investors to consistently achieve above-average returns.

• Informational Efficiency means investors can easily predict market movements

• Informational Efficiency implies that stock prices are always undervalued

What are some common tests used to assess market efficiency in the finance industry? Provide a brief explanation of each.

• Inefficient Market Hypothesis

• Random Jump Hypothesis

• Random Walk Hypothesis, Efficient Market Hypothesis, Event Study Method

• Pre-Event Study Method

Explain how the concept of behavioral finance challenges the assumptions of market efficiency using a real-world example.

• Behavioral finance challenges the assumptions of market efficiency by demonstrating that investors do not always act rationally, leading to market anomalies and inefficiencies.
