Answer:
(A) 8.22%
(B) 7.5%
Explanation:
The first step is to calculate the average nominal return
Average nominal return= R1 + R2 + R3 + R4 + R5/5
= 16 +(-5) + 19 + 13 + 10/5
= 16-5+19+13+10/5
= 53/5
= 10.6%
(A) The average real return can be calculated as follows
= (1 + average nominal return)/(1+ inflation) -1
= (1+ 10.6/100)/(1+2.2/100) -1
= (1+0.106)/(1+0.022)-1
= 1.106/1.022-1
= 1.08219-1
= 0.08219 × 100
= 8.22%
(B) The average nominal risk premium can be calculated as follows
Average risk free rate= Nominal average t-Bill rate-inflation
= 5.3% - 2.2%
= 3.10%
Average nominal risk premium= average nominal return -average risk free rate
= 10.6% - 3.10%
= 7.5%
