On the other hand, Safe, Inc. is not as risky. It has an expected return of 6% and the standard deviation of its return is 2%. The correlation coefficient of the two stock's return is -1.0. If the investor invests 50% in the Safe, Inc. stock and the rest in Risky, what are the expected return and standard deviation of the return of the portfolio? Is the portfolio more risky than Safe, Inc? Explain
