Answer:
1.71
Explanation:
Systemic risk is measured by beta. The higher beta is, the higher the systemic risk and the higher the compensation demanded for by investors
The market has a beta of one. If a portfolio has the same level of systematic risk that is the same as that of the market, its beta would be equal to 1.
The beta of a risk free asset is zero
The portfolio's beta can be determined by adding together the weighted beta of each stock in the portfolio
weighed beta of a stock = percentage of the stock in the portfolio x beta of the stock
1 = (0.3 x 1.62) + (0.3 x 0) + (0.3 x a)
1 = 0.486 + 0 + 0.3a
1 - 0.486 = 0.3a
a = 1.71
