Suppose you are wondering whether to Invest in the shares of Amazon (Security 1) or Southwest (Security 2). You decide that Security 1 offers an expected return of 10.0% and Security 2 offers an expected return of 15.0%. After looking back at the past variability of the two stocks, you also decide that the standard devation of returns is 26.6% for Security 1 and 27.9% for Security 2 Calculate the expected portfollo return and standard deviation for different values of xg and x2 assuming the correlation coefficlent P12 = 0. Repeat the problem for P12 = -0.25. (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.) op when p12 =0 x1 x2 Exp (rp) op when p12 = 0.25 1.0 0.0 0.9 0.1 0.8 0.2 0.7 0.3 0.6 0.4 0.5 0.5 0.4 0.6 0.3 0.7 0.2 0.8 0.1 0.9 0.0 1.0
