Final answer:
Using the dividend discount model (DDM), Stock B, with its initial $10 dividend and 5% growth, discounted at 7%, is the most valuable at $500.
Step-by-step explanation:
To determine which stock is the most valuable given a market capitalization rate of 7%, we use the dividend discount model (DDM) for each stock. Stock A offers a perpetual dividend of $20, which can be calculated using the formula Value = Dividend / Market Capitalization Rate. Therefore, the value of Stock A is $20 / 0.07, which equals approximately $285.71.
For Stock B, with a starting dividend of $10 and a growth rate of 5% per year, we use the Gordon Growth Model Value = D1 / (r - g), where D1 is the dividend next year. Plugging in the values we get $10 / (0.07 - 0.05), which is $500. Lastly, for Stock C, we must calculate the present value of the dividends for the next four years using the formula Present Value = Dividend / (1 + r)^t and add the present value of the perpetual dividends from year 5 onwards, applying a similar calculation as Stock A but factoring the growth over four years.
Without going into the complex calculation for Stock C, we can already see that at a 7% discount rate, Stock B has the highest present value at $500. Therefore, Stock B is the most valuable among the three.
