The optimal proportion of the risky asset in the complete portfolio is
given by the equation below
y*=
E(Rp− Rf)
A0²
For each of the variables on the right side of the equation, discuss the
impact of the variable's effect on y* and why the nature of the relationship
makes sense intuitively.
Assume the investor is risk averse
Considering the attached set of securities and portfolio returns:
Find the combination of the weights that minimizes CV of the portfolio.
How does the CV of the optimal portfolio compare with the CVs of its constituents?
An efficient portfolio is one that:
Select one:
a.
maximises return for a given level of risk.
b.
maximises risk for a given level of return.
c.
minimises risk for a given rate of return.
d.
Both A and C. are efficient portfolios.
