Now suppose you decided to sell one of your stocks that has a beta of 1.000 and to use the proceeds to buy a replacement stock with a beta of 1.750. What would the portfolios new beta be?

2) The Isberg Company just paid a dividend of $0.75 per share, and that dividend is expected to grow at a constant rate of 5.50% per year in the future. The company's beta is 1.15, the market risk premium is 5.00%, and the risk-free rate is 4.00%. What is the company's current stock price, P0?
