Portfolio Expected ReturnYou have \$10,000 to invest in a stock portfolio. Your choices are Stock X with an expected return of 12.7 percent and Stock Y with an expected return of 9.1 percent. If your goal is to create a portfolio with an expected return of 11.2 percent, how much money will you invest in Stock X? In Stock Y?

Let the weight invested in stock X be wX = x

Hence, investment in Stock Y = wY = 1-x

Hence, expected return of the portfolio = ERX*wX + ERY*wY

where, ERX is the expected return for Stock X = 12.7&%

ERY is the expected return for Stock Y = 9.1%

wX is the weight invested in Stock X and wY is the weight invested in Stock Y

Hence, portfolio return = 12.7*x + 9.1*(1-x)

This is equal to 11.2%

=> 11.2 = 12.7*x + 9.1*(1-x)

=> 11.2 = 12.7 x + 9.1 - 9.1x

=> 3.6x = 2.1

=> x = 0.5833

Hence, investment in Stock X = 0.5833*10000 = \$5833

Investment in Stock Y = (1 - 0.5833)*10000 = \$4167
