Consider the Treynor-Black model. The alpha of an active portfolio is 3%. The expected
return on the market index is 18%. The standard deviation of the return on the market
portfolio is 25%. The nonsystematic standard deviation of the active portfolio is 15%. The
risk-free rate of return is 6%. The beta of the active portfolio is 1.2. The optimal proportion
to invest in the active portfolio is

According to the Treynor-Black model, the weight of a security in the active portfolio
depends on the ratio of __________ to __________.
36.
One property of a risky portfolio that combines an active portfolio of mispriced securities
