Historical Stock PricesFor Development Research purposes, we either value stock information at the current value or the historical value, depending on the date of the information we have about stock ownership. A total return index for stocks can be computed by assuming that all dividends are reinvested by buying additional shares of the stock. Two major factors affect stock prices: earnings, which determine the dividends on the stocks; and interest rates , which discount” future cash payments to the present. Therefore, stock prices may not fall and may actually rise when interest rates rise. Notwithstanding, low-interest-rate environments are usually deemed good for the stock market, and stocks usually respond favorably when the Federal Reserve lowers rates and unfavorably when it raises rates.
