Stock Market Indexes, Pricing, and Risk
Stock market indexes are used to compute an “average” price for groups of stocks. A stock market index attempts to mirror the performance of the group of stocks it represents through the use of one number, the index. Indexes may represent the performance of all stocks in an exchange or a smaller group of stocks, such as an industrial or technological sector of the market. In addition, there are foreign and international indexes.
