Required:

(i) Compare Assets A and B. Which asset has greater total risk?

Which has greater systematic risk? Which has greater

unsystematic risk? Which asset has a higher risk premium?

(ii) A portfolio is constructed with 40% invested in A, 60% in B.

What is the portfolio's Beta? What is the standard deviation

of the portfolio?

(iii) Assume you want to construct an equally-weighted portfolio

with only two assets and you want the portfolio to have the

MINIMUM risk, which two assets should you include into the

portfolio? and what is the portfolio's risk?

(iv) Portfolio A is an equally-weighted portfolio with Asset A and

B; Portfolio B is an equally-weighted portfolio with Asset A, B

and C. which portfolio has smaller standard deviation?

(v) If the risk free rate of interest is 4%, what are the Sharpe ratios

of Asset A and B. Compare the two assets' performance

based on their Sharpe ratios.
