Answer: 0.9875
Explanation:
Portfolio beta is the measure of the volatility of a portfolio or security when it is compared to the market.
From the question, we are informed that an investment of $200,000 was made for four stock types. This means each stock's investment was: ($200,000/4) = $50,000. Therefore a weightage of (100% ÷ 4) = 25% will be assigned to each.
The portfolio beta will now be:
= (25% × 0.95) + (25% × 0.8) + (25% × 1) + (25% × 1.2)
= (0.25 × 0.95) + (0.25 × 0.8) + (0.25 × 1) + (0.25 × 1.2)
= 0.2375 + 0.2 + 0.25 + 0.3
= 0.9875
The portfolio's beta is 0.9875
