Market Index
Explanation: A market index is a hypothetical portfolio of investment holdings that represents a segment of the financial market. The calculation of the index value comes from the prices of the underlying holdings. Common examples include the S&P 500, Dow Jones Industrial Average (DJIA), and NASDAQ Composite. Market indices are used to track the performance of the stock market and serve as benchmarks for mutual funds, ETFs, and other investment products.
Example: The S&P 500 index includes 500 of the largest publicly traded companies in the U.S. It serves as a benchmark for many mutual funds and ETFs, helping investors gauge the overall performance of the U.S. stock market.
