It is common to measure value-at-risk over short horizons of a day or a week. We might define such horizons in terms of actual days or trading days. To avoid having the end of a horizon fall on a weekend or holiday, we adopt the latter convention. A “1-day horizon” comprises 1 trading day. A “5-day horizon” comprises 5 trading days.

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. Value-at-Risk (VaR) is, in essence, the X-percentile of the projected Profit-and-loss (PnL) for our portfolio, over a given time horizon. 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.

This chapter discusses the notion of value-at-risk (VaR) and its alternatives and its role in quantifying and managing of operational risk. VaR has been a benchmark for risk-based internal models for measuring market and credit risk for a number of years. This basis can be extended for internal measurement of operational risk. Variance is calculated by subtracting the average return from each individual return, squaring that figure, summing the squares across all observations, and dividing the sum by the number of observations. The square root of the variance, called the standard deviation or the volatility, can be used to estimate risk. what about my birthday Using a 95% confidence level, identify the value at risk.
