Soln : Expected return on TSX index or market return, m = 10%, risk free rate, R = 6%
a) Required rate of return(r) can be calculated by using the CAPM model here with the help of given factors.
CAPM Model , r = R + market risk premium * beta of stock
rPII = 6 + (10-6)*1.25 = 6 + 4*1.25 = 11% = Required rate of return for PII
Similarly, rSVT = 6 + (10-6) *1.30 = 6 + 5.2 = 11.2% = Required rate of return for SVT
(b) Now, need to calculate the better option to invest, to compare the 2 stocks we can use the Treynor ratio for both stock
For PII, treynor ratio = (Stock return - risk free rate)/beta of stock
Stock return = (50.45-45)/45 = 12.11%
Treynor ratio = (12.11- 6)/1.25 = 4.89
Similarly in case of SVT,
Treynor ratio = (14-6)/1.30 = 6.15
So, Treynor ratio is more for SVT , hence it is better option to choose for investment.
c) Total amount invested in PII = 400*45 = $18000
Amount invested in SVT = 300*50 = $15000
Total amount of portfolio = $33000
Now, beta of portfolio = (18000/33000) *1.25 + (15000/33000)*1.30 = 0.682 +0.591 = 1.273
Portfolio beta = 1.273
