Answer

Brief Explanations:

A market index is a statistical measure that tracks the value of a specific group of stocks or other assets. It serves as a benchmark to evaluate the overall performance of a particular market or a specific sector within the economy. By aggregating the price movements of multiple securities, it provides a snapshot of how the market is trending as a whole, rather than focusing on the performance of an individual stock or broad economic indicators like GDP.

Answer:

An index measures market performance.
