Answer:
r fund = 0.11356617647 or 11.356617647% rounded off to 11.36
Explanation:
The required rate of return on the fund can be calculated using the CAPM equation. The equation is as follows,
r fund = rRF + beta * (rM - rRF)
Where,
To calculate the required rate of return of the fund, we first need to calculate the fund beta. The beta on fund can be calculated using the formula for portfolio beta which is,
Portfolio Beta = wA * Beta of A + wB * Beta of B + ... + wN * Beta of N
Where,
Portfolio or fund beta = 320000/4080000 * 1.5 + 540000/4080000 * -0.5 + 1420000/4080000 * 1.25 + 1800000/4080000 * 0.75
Portfolio or fund beta = 0.81740196078 rounded off to 0.82
The required rate of return on fund will be,
r fund = 4% + 0.81740196078 * (13% - 4%)
r fund = 0.11356617647 or 11.356617647% rounded off to 11.36
