Suppose Mr. Thomas, president of your company, has hired you to determine the firm's cost of debt and the cost of equity capital. The stock is selling fir $50 per share now, and the dividend per share will probably be about $5. Mr. Thomas argues, "It will cost us $5 per share to use the shareholders' money this year, so the cost of equity is equal to 10 percent ($5/50)." What is wrong with this conclusion?
