Index
An index is a statistical measure that tracks the performance of a group of assets, such as stocks, bonds, or commodities. Indices are often used as benchmarks to evaluate the performance of investment portfolios or specific markets. Common examples include the S&P 500, which tracks the performance of 500 large U.S. companies, and the Dow Jones Industrial Average (DJIA). Indices help investors gauge market trends and compare the returns of their investments against the broader market.
