If a stock has a required rate of return r = 12% and its dividend is expected to grow at a constant rate of 5%, then the stock's dividend yield is also 5%. The stock valuation model, Po=D/(rs - g), can be used to value firms whose dividends are expected to decline at a constant rate, i.e., to grow at a negative rate.
