Realized rate of return is the minimum expected return an investor would require from any investment. It refers to the kinds of return an individual could get from a stock. It includes Capital Gains and Dividend payments. An individual can get capital gain by selling the stock, if the price of the stock appreciates. He may also end up having a loss.
