Using the CAPM model, assuming a risk-free rate of 1% and a expected market return of 10%, choose 4 stocks of your choice and calculate the expected return of each stock. Additionally, assuming that the 4 stocks make up your portfolio and have a weighting of 10% for the 1st stock, 20% for the 2nd stock, 30% for the 3rd stock, and 40% for the 4th stock, what is the Beta and the expected return of the portfolio?
