A portfolio has Rs 60,000 invested in Share A with beta 1.2 and Rs 40,000 in Share B with beta 0.8. The portfolio beta is:

The portfolio beta is 1.04. Portfolio beta is the weighted average of individual betas using investment proportions: 60% times 1.2 gives 0.72 and 40% times 0.8 gives 0.32, totalling 1.04. A simple average of 1.00 ignores the weights.

  1. A1.00
  2. B1.04Correct
  3. C1.10
  4. D0.96

Explanation

Weights are 0.6 and 0.4. Portfolio beta = 0.6 x 1.2 + 0.4 x 0.8 = 0.72 + 0.32 = 1.04. Option A is the simple average, which ignores the unequal weights.
