Minimum Variance Portfolio

Assignment:

A portfolio manager may create a portfolio with the following two assets. Asset A

is an Asian-Stock-Index product and asset B is a BRIC bond-index product. The

expected return of asset A is 10% (asset B 7% ) and the volatility of asset A is 20%

(asset B 10%). According to historical data, the correlation is expected to be 0,4.

How is the loading of the MVP?

What is the expected risk and return of the MVP?

The Ideal Portfolio

1. Assignment

A portfolio manager needs to create a portfolio for a new client who has a risk

aversion of a = 4. The manager can choose between two assets A and B. The

following information is being provided to the manager: µA = 10%, µB = 5%, σA =

20%, σB = 10%, ρA,B = 0,3.

Which is the ideal portfolio loading for the client?

2. Assignment

Another client of the manager has already a portfolio set up.

The portfolio loading is 68,7% stocks and 31,3% bonds. Additional portfolio

information: µA = 10%, µB = 5%, σA = 20%, σB = 6%, ρA,B = 0,3.

What is the client’s risk-aversion factor that the manager needs to know to offer the

client an additional product?

MPT - Risky and Risk-Free Assets

Assignment

An investors’ utility function is given by

U(RQ ) = f (µ Q ," Q ) = µ Q(w)# a

Q(w)

What is the loading, which maximizes the investors utility?

The market portfolio (tangential portfolio) has µM = 10% and σM = 20%. The risk

free rate is given by an investment in a AAA government bond with rf = 5%.

Calculate the ideal asset allocation for client A who has a risk aversion of a=1,

client B (a=1,25), client C (a=3), and client D (a=4)
