2. Q1
Stock X has a beta of 1.5 and a rate of return of 22%. Stock Y has a beta of 0.25 and a rate of return of 12%. What is the market rate of return?
Change of beta of 1.25, and change in rate of return of 10%.
So change in beta of 1 yields change in rate of return of 10/1.25= 8%.

Beta of 1, return of return is 18% (22%-0.5×8%).

s.d= =
Variance of portfolio:
(0.5^2)×(.02)+0+(0.5^2)×(0)=0.005
(bond is risk-free, so the covariance is 0)

X= , (rule out)
r= %
