Answer:
11.87% (12% to the nearest whole percentage)
Step-by-step explanation:
From the perspective of time value of money,we understand that the value of stock after 3 years is the future value while the initial amount at which it was bought is the present value, on that premise,we can determine the annual rate of return using the formula below which shows the relates future and present values together:
FV=PV*(1+r)^n
FV=future value=$70
PV=present value=$50
r=annual rate of return which is unknown
n=investment timing horizon=3
70=50*(1+r)^3
70/50=(1+r)^3
divide indices on both sides by 3
(70/50)^(1/3)=1+r
r=(70/50)^(1/3)-1
r=11.87%
