Assume a risk-free rate of 3.5 percent and an expected market return of 13 percent with a standard deviation of 20 percent. You approach your broker to borrow money against securities held in your portfolio. Even though the loan will be secured by the securities in your portfolio, the brokers rate for lending to customers is 6.5 percent. Estimate your expected return and risk if you decide to borrow 35 percent of your initial wealth and invest all your money in the market. (pls with detail explanation NOT on excel)
