Answer

Brief Explanations:

A market index is a statistical measure that reflects the performance of a group of stocks or other securities, representing a segment of the market. It gives an overall picture of how well the market or a particular sector is performing. Economic trends are broader and not the main focus of a market - index. Growth is a part of performance but not as comprehensive. A market index does not measure a single - stock performance.

Answer:

An index measures market performance.
