Value-at-risk (VAR) Value-at-risk is a statistical measure of the riskiness of financial entities or portfolios of assets.

Value of risk refers to the financial benefit that stakeholders of an organization gain by pursuing a risk-taking activity. The amount of risk involved in any activity depends on the type of activity and the ability of the company to recoup costs incurred. Each activity carries an opportunity cost, which is the benefit foregone by ... Value-at-risk, also know as VaR, is a metric introduced by JP Morgan indicating the total risk of a portfolio in a single number. In technical terms, value-at-risk indicates that with a certain probability, over a given period of time, the loss of a portfolio will not be greater than x. For example, the VaR for 10 days with 99% could be 1,000,000. Value at risk (VaR) example. The value at risk to a position is calculated by assessing the amount of potential loss, the probability of the loss and the time frame during which it might occur. This is normally then presented as a percentage within a given timeframe. For example, it could be said that an asset has a 2% one-week VaR of 1%.

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.

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.

4.5 Hypothesis Testing. In statistics, a hypothesis is a probabilistic assertion. A hypothesis might assert that a random variable’s mean is 1—or perhaps that its variance is less than 5. A hypothesis might state that a random variable is normally distributed. It might assert that two random variables are independent—or that they have the ...such as value-at-risk (VAR) which is a widely adopted risk measure in real-world applications (e.g., banking (Basel Committee on Banking Supervision,2006)).

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 was not widely used prior to the mid-1990s, the origins of Value at Risk lie further back in time.
