Indexes of the American Stock Exchange (AMEX)

American Stock Exchange publishes two major indexes, which are calculated on an entirely different basis.The main market index of the American Stock Exchange (AMEX Major Market Index) is a simple average of the price movements of 20 leading industrial corporations. It was conceived by the American Stock Exchange as a kind of substitute for the Dow Jones industrial average. Although it is calculated and published by the American Stock Exchange, it consists of shares of corporations listed on the New York Stock Exchange. It is noteworthy that 15 of them are also components of the Dow Jones industrial average. Transactions in futures on this index are carried out on the Chicago Mercantile Exchange.

The index of the market value of the American Stock Exchange (AMEX Market Value Index) is calculated on the basis of a fundamentally different: it is an index weighted by the market value of all issued shares of those corporations that are included in it as a component. It was first published in September 1973. It includes as a component of more than 800 issues of shares representing securities of corporations of all major industry groups registered on the American Stock Exchange, including, in addition to common stock, American depositary receipts and subscription certificates. From a technical point of view it is unique due to the fact that in its calculation assumes the form of cash dividends paid by its member shares are reinvested and, on this basis, they are reflected in the index. Options on the index are traded on the American Stock Exchange.
