Answer:
D0 = $0.8
Explanation:
Using the constant growth model of dividend discount model, we can calculate the price of the stock today. The DDM values a stock based on the present value of the expected future dividends from the stock. The formula for price today under this model is,
P0 = D0 * (1+g) / (r - g)
Where,
Plugging in the values in the formula for P0, r and g, we can calculate the last dividend paid (D0) to be,
21 = D0 * (1+0.05) / (0.09 - 0.05)
21 = D0 * (1+0.05) / 0.04
21 * 0.04 = D0 * (1+0.05)
0.84 / (1+0.05) = D0
D0 = $0.8
