Answer:
15.26%
Explanation:
Given:
Expected return = 15.1% = 0.151
Expected loss in recession = - 8% = - 0.08 [negative sign depicts loss]
Expected earning in a boom = 18% = 0.18
Probabilities of a recession = 2% = 0.02
Probabilities of a normal economy = 87% = 0.87
Probabilities of a boom = 11% = 0.11
Now,
Expected return = ∑ (Probability × Return)
or
0.151 = 0.02 × ( - 0.08) + 0.11 × 0.18 + 0.87 × Return on normal economy
or
0.151 = - 0.0016 + 0.0198 + 0.87 × Return on normal economy
or
0.151 - 0.0182 = 0.87 × Return on normal economy
or
Return on normal economy = 0.1526
or
= 0.1526 × 100%
= 15.26%
