Given the following information for the stock of foster company, calculate its beta.

Current price per share of comment Rs 80.00
Expected dividend per share next year Rs 5.00
Constant annual dividend growth rate 7%
Risk free rate of return 6%
Return of market portofolio 10%

Po* = DIV1 / {rRF + (rM - rRF) * βA – g}
80 = 5/ {6% + (10% - 6%)* βA – 7%}
80 = 5/ {6% + (4%)* βA – 7%}
80 = 5/ {(4%)* βA – 1%}
{(4%)* βA – 1%}*80 = 5
{(4%)* βA – 1%} = 5/80 = 0.0625
(4%)* βA = 0.0625 + 1% = 0.0625 + 0.01 = 0.0725
βA = 0.0725/4% = 0.0725/ 0.04 = 1.8125 Ans
