M-
Risk and return characteristics
Expected monthly returns % Standard deviation of monthly returns S“.
Original portfolio ot67 2-37

a. The inheritance changes Grace’s overall portfolio and she is deciding whether to keep the ABC stock. Asswmg
Grace keeps the ABC stock. calculate the:
i. expected return of her new portfolio which includes the ABC stock.
