indicators used to measure and report value changes in representative stock groupings. Strictly speaking, an average is simply the arithmetic mean of a group of prices, whereas an index is an average expressed in relation to an earlier established base market value. (In practice, the distinction between indices and averages is not always clear; the AMEX Major Market Index is an average, for example.) Indices and averages may be broad based-comprised of many stocks representative of the overall market -or narrowly based, meaning they are composed of a smaller number of stocks reflecting a particular industry or market sector. Selected indices and averages are also used as the underlying value of stock index futures, index options, or options on index futures; these derivative instruments enable investors to hedge a position against general market movement at relatively low cost. An extensive number and variety of indices and averages exist. Among the best known and most widely used are
AMEX Composite Index (XAX): introduced in January 1997, it is a market capitalization-weighted, price appreciation index with a base level of 550 as of December 29, 1995. XAX reflects the aggregate market value of all of its components relative to their aggregate value on December 29, 1995. The index includes common stocks, or American Depositary Receipt of all AMEX-listed companies, REITs, master limited partnerships, and closed-end investment funds. Each component's market value is determined by multiplying its price by the number of shares outstanding. The day-to-day price change in each issue is weighted by its market value at the start of the day as a percent of the total market value for all components. The level of the index is not altered by stock splits, stock dividends, trading halts, new listings, additional issuances, delistings, or suspensions. www.amex.com.
AMEX Major Market Index (XMI): American Stock Exchange's price-weighted average of 20 blue chip industrial stocks representative of major U.S. corporations; several of the stocks are components of the dow jones industrial average (DJIA).

The Dow's components, which were once entirely industrial companies, have shifted with market dynamics and now represent a range of industries, including telecommunications, technology, consumer services, and financials. The components generally represent 20%-25% of the market value of U.S. stocks. The Dow is calculated by adding the trading prices of the component stocks and using a divisor adjusted for stock dividends and splits. cash equivalent distributions equivalent to 10% or more of the closing prices of an issue, and substitutions and mergers. The average is quoted in points, not dollars. The Dow underlies a variety of investment products, inlcuding one of the largest U.S. exchange-traded funds, diamonds, which are are traded on the American Stock Exchange. Other averages similarly maintained by Dow Jones Indexes are the Dow Jones Transportation Average-20 stocks representative of the airline, trucking, railroad, and shipping businesses (see also dow theory); and the Dow Jones Utility Average-15 geographically representative gas and electric utilities.
