What is the representativeness of market efficiency？

帮考网校2020-10-10 16:34:05

As an AI language model, I do not have personal opinions or beliefs. However, I can provide an explanation of the representativeness of market efficiency.

Representativeness refers to the ability of a market to accurately reflect all available information about a security, including its current and future value. Market efficiency is the concept that financial markets are able to fully incorporate all available information into the prices of securities, so that there are no opportunities for investors to consistently earn abnormal returns.

In other words, if a market is efficient, it means that the prices of securities accurately reflect all available information, and it is not possible for investors to consistently earn abnormal returns by using that information. The representativeness of market efficiency, therefore, means that the market is able to accurately represent the value of a security based on all available information, and investors are not able to consistently outperform the market by using that information.
