Qestion1 Data description and risk measurements
The data description of 5 assets is presented by the table1.1

KLM 4.8282 2.5% 0.698% 16.383%
AHOLD 16.0442 8.3% 0.655% 12.011%
HEINKEN 18.4926 9.6% 0.721% 7.111%
SHELL 114.682 59.3% 0.452% 6.696%
UNILEVER 39.4007 20.4% 0.679% 7.114%
The expected monthly return of the portfolio is calculated as: Rp=w’μ=0.547%
The risk of portfolio is calculated by the
σ_p^2=w’Σw= 0.38% σp= 6.20% (Σ can be found in Appedix 1.1)
Suppose the initial wealth to be €250,000, the monthly 99% Value at Risk is computed in the following equation:
VaR=Wt(2.33×σ-μ)= 34740.69
In order to calculate the GUISE, we need to compute the geometric monthly return using the method: geometric average= arithmetic average- 1/2 σ^2
Annualized σ = monthly σ×√12=6.20%×√12=21.47%
Annualized geometric average return= 0.547%×12-0.5×0.21472= 4.258%
GUISE is calculated by x(0.10)=0.3125×x(0.01)+0.4375×x(0.05)+0.2500×x(0.10)

GUISE 224933.75
VaR (value at risk)is the maximum amount that we are going to lose with a certain probability. In this case, there is 1% possibility of the conditions that we will lose more than €34740.69 with an investment of €250000. On the other hand GUISE described the expected payoff in the 10% worst scenario. Here we could expect €224933.75 as payments in the worst case. It implies that the loss in the worst 10% stage will be €25066.25, which is smaller than 99%
