Q1) UPS, a delivery services company, has a beta of 1.1, and Wal-Mart has a beta of 0.7. The risk-free rate of interest is 4% and the market risk premium is 7%. What is the expected return on a portfolio with 30% of its money in UPS and the rest in Wal-Mart? Q2) IBM’s σ = 0.22; Dell’s σ = 0.13. The correlation between Dell and IBM is 0.32, and the weights are 50% each. Find the portfolio volatility (standard deviation). If the weights are now 30 % and 70 % for Dell and IBM respectively, how would the volatility of portfolio change? Briefly justify your answer.
Risk and return
Before understanding the concept of Risk and Return in Financial Management, understanding the two-concept Risk and return individually is necessary.
Capital Asset Pricing Model
Capital asset pricing model, also known as CAPM, shows the relationship between the expected return of the investment and the market at risk. This concept is basically used particularly in the case of stocks or shares. It is also used across finance for pricing assets that have higher risk identity and for evaluating the expected returns for the assets given the risk of those assets and also the cost of capital.
