Answer:
APR = 14.28%
EAR = 14.7%
Step-by-step explanation:
Stock price = $80.82
Current stock price = $86.59
The return will be as below since no dividend was stated
R = ($86.59 - $80.82) / 80.82
R = 0.0714
R = 7.14%
For six months, the return was 7.14%
Annual percentage yield (APR) = 2*(7.14%) = = 14.28%. Therefore, the value of APR = 14.28%
Effective Annual Return = [1 + (Annual Rate/ N )] ^N - 1
= [1 + (14.28% / 2]^2 - 1
= [1 + 0.071]^2 -1
= 1.147 - 1
= 0.147
= 14.7%
