A random value is numerical, has no regularity, and cannot be predicted. The Monte Carlo simulation method is as follows. First, a random number is used to repeatedly generate an expected value of the risk factor. Second, the present value of the asset/liability corresponding to the fluctuation values of the risk factors is calculated. Methodology: Review of One Asset VaR. Collect price data. Create return series. Estimate variance of return series. Take square root of variance to get volatility (standard deviation ) Multiply volatility by 2.33 by position size to get estimate of 99% worst case loss.

Interpolation is any procedure for fitting a function to a set of points in such a manner that the function intercepts each of the points. Consider m points ( x[k], y[k]) where x[k] n, y[k] , and the x[k] are distinct. We wish to construct a function f : n → such that y[k] = f ( x[k]) for all k.

In the first edition, I stated firmly that I defined value-at-risk as applicable to market risk only. At the time—back in 2003—“credit VaR” measures were flourishing.

In plain words, if VaR is $100, it tells you that if we are unlucky tomorrow, we expect to lose at a maximum of $100 with X% chance/confidence. Let’s think about it in a non-financial example.

Step 1 – From the given time series (of portfolio returns) calculate the maximum and minimum return. To do this, we can use the ‘=Max ()’ and ‘=Min ()’ function on excel. Step 2 – Estimate the number of data points. The number of data points is quite straight forward. We can use the ‘=count ()’ function for this. The value at risk is $1.7 million. In other words, the market risk of this portfolio can be communicated effectively to a non-technical audience with a statement such as: Under normal market conditions, the most the portfolio can lose over a month is $1.7 million.

A 95% confidence level will identify the reduced value of the portfolio that has a 5% chance of occurring. From the normal distribution tables, 1.65 is the normal distribution value for a one-tailed 5% probability level. Since the value is below the mean, -1.65 will be needed. 8.6 Example: Options.
