Beta |
Total Portfolio value = price of Stock A*Shares of Stock A + price of Stock B*Shares of Stock B + price of Stock C*Shares of Stock C |
=60*500+80*405+41*500 |
=82900 |
Weight of Stock A = price of Stock A*Shares of Stock A/Total Portfolio Value |
= 30000/82900 |
=0.3619 |
Weight of Stock B = price of Stock B*Shares of Stock B/Total Portfolio Value |
= 32400/82900 |
=0.3908 |
Weight of Stock C = price of Stock C*Shares of Stock C/Total Portfolio Value |
= 20500/82900 |
=0.2473 |
Beta of Portfolio = Weight of Stock A*Beta of Stock A+Weight of Stock B*Beta of Stock B+Weight of Stock C*Beta of Stock C |
Beta of Portfolio = 0.8*0.3619+1.8*0.3908+0.7*0.2473 |
Beta of Portfolio = 1.17 |
