VaR Approach Specific Steps Calculating Variance-Covariance (VCV) Value at Risk (VaR)

This method assumes that the daily returns follow a normal distribution. From the distribution of daily returns we estimate the standard deviation (σ). The daily Value at Risk (VaR) is a function of the standard deviation and the desired confidence level. In the Variance-Covariance (VCV)  method the underlying volatility may be calculated either using a simple moving average (SMA) or…

Master Class: Calculating Value at Risk (VaR): VaR Methods

There are three primary methods used for calculating Value at Risk (VaR).

a. Variance /Covariance method

b. Historical simulation method

c. Monte Carlo simulation method

All methods have a common base but then diverge in how they actually calculate Value at Risk (VaR). They also have a common problem in assuming that the future will follow the past. This shortcoming is normally addressed by supplementing any…

Master Class: Calculating Value at Risk (VaR): Introduction

Value at Risk (VaR)

One of the most pertinent questions in risk management has been: How much do you stand to lose, over a certain period and with a certain probability? The most common answer to this question today is Value at Risk, a risk measure that expresses itself as one number. What is that number and what does it stands for?

 In order to interpret this number…
