NYSE Composite Index Law and Legal Definition
NYSE Composite Index is the composite index covering price movements of all common stocks listed on the New York Stock Exchange. It is based on the close of the market December 31, 1965, as 50 and is weighted according to the number of shares listed for each issue. The index is computed continuously and printed on the ticker tape. Point changes in the index are converted to dollars and cents so as to provide a meaningful measure of changes in the average price of listed stocks. The composite index is supplemented by separate indexes for four industry groups: industrial, transportation, utility and finance.
