Calculate the expected return and portfolio variance assuming
you invest $100,000 in stock A, $200,000 in stock B, and $300,000
in stock C.
How does this answer in (A) compare to investing in stock B
alone?
Calculate the expected return and portfolio variance assuming
you invest $200,000 in each stock.
Explain the difference between your answers in (A) and in
(C).
Now assume that, in addition to the above investments in (A),
you invest an additional $400,000 in long-term Treasury securities
earning 4%. Calculate the expected return and variance
of this 4-security portfolio worth $1,000,000.
