Question 4
Suppose a risk-free asset has a 3 percent return and a second risky asset has a 15 percent expected return with a standard deviation of 25 percent. Calculate the expected return and standard deviation of a portfolio consisting of 15 percent of the risk-free asset and 85 percent of the second asset.
Expected return of a portfolio is weighted average of the return of the components.
E(R) = w1 * R1 + w2 * R2
E(R) = 15% * 3% + 85% * 15%
E(R) = 0.45% + 12.75%
E(R) = 13.20%
Standard deviation of portfolio is mathematically represented as:
Now, standard deviation of risk free asset = 0, and its correlation of returns with risky asset is also 0.
Standard deviation of portfolio = 21.25%
