A stock - or equities - market lists companies whose stock is publicly traded. A stock market index - or simply a market index - is used to evaluate the performance of a stock market or individual sector within the market. Because stock price is intrinsically linked to the value of a company or the sector in which the company operates, investors review the leading stock market indicators to evaluate current economic conditions or to try to determine future conditions. Market indices are often quoted by news services when describing current market conditions.
