You are a Portfolio Manager who has a Stock Fund, a Bond Fund and a Treasury Bill Fund. The Stock Fund has an expected return of 13.2% and an expected volatility of 17.4%. The Bond Fund has an expected return of 4.1% and an expected volatility of 4.9%. The T-Bill fund will yield a return of 2.4%. The correlation coefficient between the two risky assets is 0.21. If your client directs you to manage her $80,000 in an efficient way that targets a return of 7% and if she directs you to create a Total Portfolio of the three funds, what will be the volatility of her Total Portfolio?
