Answer:
10.9%
Explanation:
to calculate the expected return of the portfolio, we first need to calculate the portfolio's beta:
the portfolio beta = (beta UPS stock x weight UPS stock) + (beta Walmart stock x weight Walmart) = (1.4 x 50%) + (0.9 x 50%) = 0.7 + 0.45 = 1.15
portfolio's expected return = risk free rate + (portfolio beta x market risk premium) = 4% + (1.15 x 6%) = 4% + 6.9% = 10.9%
