VAR-Monte Carlo method
A Monte Carlo output specifies the expected 1-week portfolio
return and standard deviation as 0.00188 and 0.0125,
respectively.
Calculate the 1-week value at risk at 5% significance.
Advantage: the ability to incorporate any returns distribution or
asset correlation .
Disadvantage: The analyst must make thousands of
assumptions about the returns distributions for all inputs as
well as their correlations . The seeming sophistication of the
method can also lead to a false sense of securities (garbage in,
garbage out)

Assume we calculate a one-week VaR for a natural gas
position by rescaling the daily VaR using the square-root rule.
Let us now assume that we determine the “true” gas price
process to be mean reverting and recalculate the VaR. Which
of the following statements is true?
A. The recalculated VaR will be less than the original VaR.
B. The recalculated VaR will be equal to the original VaR
C. The recalculated VaR will be greater than the original VaR
D. There is no necessary relation between the recalculated VaR
and the original VaR
