Answer:
The portfolio's expected return is 15%
Explanation:
The expected return of a portfolio is the sum of the weight of each asset times the expected return of each asset.
So, the expected return of the portfolio is:
E(RP) = 0.20(.09) + 0.60(.15) + 0.20(.21)
= 0.018 + 0.09 + 0.042
E(RP) = 0.15 or 15%
If we own this portfolio, we would expect to earn a return of 15 percent.
