Answer:
10.24%
Step-by-step explanation:
the expected return on a portfolio can be determined using CAPM
According to the capital asset price model: Expected rate of return = risk free + beta x (market rate of return - risk free rate of return)
Beta of the portfolio = (percentage of UPS in portfolio x beta of UPS) + (percentage of Wal-mart in portfolio x beta of Wal - Mart )
(1.4 x 0.4) + (0.8 x 0.6)
= 0.56 + 0.48
= 1.040
Expected return = 4% + (1.040 x 6%) = 10.24%
