Question: As discussed in Section 8.3, the Markowitz model uses the variance of the portfolio as the measure of risk. However, variance includes deviations both below

As discussed in Section 8.3, the Markowitz model uses the variance of the portfolio as the measure of risk. However, variance includes deviations both below and above the mean return. Semivariance includes only deviations below the mean and is considered by many to be a better measure of risk.(a)Develop a model that minimizes semivariance for the Hauck Financial data given in the file HauckData with a required return of 10%.

Assume

that the five planning scenarios in the Hauck Financial Services model are equally likely to occur.Hint: Modify model (8.10)-(8.19). Define a variabledsfor each scenario and let

dsRRs

with

ds0.

Then make the objective function:

Let

FS=proportion of portfolio invested in the foreign stock mutual fund
IB=proportion of portfolio invested in the intermediate-term bond fund
LG=proportion of portfolio invested in the large-cap growth fund
LV=proportion of portfolio invested in the large-cap value fund
SG=proportion of portfolio invested in the small-cap growth fund
SV=proportion of portfolio invested in the small-cap value fund
R=the expected return of the portfolio
Rs=the return of the portfolio in years.
