A stock price index is a numerical value calculated by a certain method to show the price movements of individual stocks to indicate the overall market movements. The Nikkei Stock Average and the Tokyo Stock Exchange Stock Price Index (TOPIX) in Japan and the New York Dow in the U.S. are well-known indices. In such cases, stock price indices are used as a representative, average, or standard for each market. Stock indices are often used in conjunction with economic trends, as stock prices reflect prospects.
