The interpretation is that there is a 0.05 probability that things would be worse than the value at this risk level. Thus the greater the degree of assurance, the lower the value at risk return. The value at the risk level of 0.01 would only be 0.694609. Value-at-Risk ($) = Value-at-Risk (%) x Portfolio Value ($) = 0.1% x $1,000,000 = $1,000. Confidence Intervals for Value-at-Risk.

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.

Value-at-Risk (VaR) concepts can be traced back to the late 1980s where financial firms began to adopt VaR to measure the risk exposure of their trading portfolios. J.P. Morgan released the RiskMetrics TM in October 1994 in an attempt to standardise the application of VaR in industry. It is the probability that a portfolio will experience a mark-to-market loss that exceeds that of a specific predetermined threshold value. Essentially this means that value at risk is measured in three variables: The timeframe. The most common parameters for VaR are 1%, 5%, and 10% probabilities and time periods of one day, two weeks, or a month. 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.
