What is indices meaning?

In finance, indices refer to statistical measures that give an indication of the performance of a particular market, sector or industry. An index essentially tracks a group of assets, such as stocks, bonds or commodities, and measures the changes in the values of those assets over time. Indices are used by investors to understand and assess the performance of particular markets or sectors, as well as to make investment decisions. There are many different types of indices, including stock market indices, bond market indices, commodity indices, and currency indices. Examples of well-known indices include the S&P 500, NASDAQ, Dow Jones Industrial Average, FTSE 100 and Nikkei 225.
