CAPM, PORTFOLIO RISK, AND RETURN
Consider the following information for stocks A, B, and C. The returns on the three stocks are positively correlated, but they are not perfectly correlated. (That is, each of the correlation coefficients is between 0 and 1.)
Stock | Expected Return | Standard Deviation | Beta | ||
A | 9.00% | 16% | 0.8 | ||
B | 11.00 | 16 | 1.2 | ||
C | 13.00 | 16 | 1.6 |
Fund P has one-third of its funds invested in each of the three stocks. The risk-free rate is 5%, and the market is in equilibrium. (That is, required returns equal expected returns.)
a.
using stock a data
As per CAPM |
expected return = risk-free rate + beta * (Market risk premium) |
9 = 5 + 0.8 * (Market risk premium%) |
Market risk premium% = 5 |
b.
Beta of fund = weight of A*beta of A +weight of B*beta of B +weight of C*beta of C
=1/3*0.8+1/3*1.2+1/3*1.6
=1.2
c.
Beta of fund = weight of A*return of A +weight of B* return of B +weight of C* return of C
=1/3*9+1/3*11+1/3*13
=11%
d.
std dev of fund will be lesser than 16% as std dev for all = 16% and the stocks are not perfectly correlated thus correlation factor is less than 1
