Choosing a VaR Report Method

Use this dialog box to choose and define your desired method of computing a Value at Risk report. The box includes three tabs, one for each method: Monte Carlo, Historical and RiskMetric. Follow these steps:

Tab 1: Monte Carlo

Step 1: In the Holding Period menu, type in the number, then click the associated time period during which the portfolio or instrument value at risk will be computed. This is a required command.

 

Step 2: In the Confidence Internal menu, type the percent level. This is a required command.

 

Step 3: In the Parametric menu, if you click Parametric, VaR will be based on the standard deviation of the observed distribution, assuming the distribution is itself normal.

 

If you choose Non-Parametric, VaR will be based on the observed distribution under simulation.

Tab 2: Historical

Step 1: in the Holding Period menu, click the associated time period during which the portfolio or instrument value at risk will be computed. This is a required command.

 

Step 2: in the Confidence Internal menu, type the percent level. This is a required command.

 

Step 3: In the Parametric menu, if you click Parametric, VaR will be based on the standard deviation of the observed distribution, assuming the distribution is itself normal.

 

If you choose Non-Parametric, VaR will be based on the observed distribution under simulation.

Tab 3: RiskMetrics

This method assumes independence among risk factors as well as normal distribution for all risk factors.

 

Step 1: In the Holding Period menu, type in the number, then click the associated time period during which the portfolio or instrument value at risk will be computed. This is a required command.

 

Step 2: in the Confidence Internal menu, type the percent level. This is a required command.
