Definition: Share price indices are calculated from the prices of common shares of companies traded on national or foreign stock exchanges. They are usually determined by the stock exchange, using the closing daily values for the monthly data, and normally expressed as simple arithmetic averages of the daily data.
A price index measures changes in the market capitalization of the basket of shares in the index.
Share price indices reflect the corporate sector's underlying profit and growth record and also act like a barometer of investor confidence in the state of industry and the economy.
