A risk manager reports that a portfolio's one-day 99% VaR is USD 5 million. Which interpretation is correct?
At 99% confidence, a USD 5 million one-day VaR means there is a 1% probability that the loss over one day exceeds USD 5 million. It is a loss quantile, not a maximum loss and not the average loss in the tail.
- AThe portfolio is expected to lose USD 5 million on average on the worst 1% of days
- BThere is a 1% probability that the one-day loss exceeds USD 5 millionCorrect
- CThe maximum possible one-day loss is USD 5 million
- DThe portfolio will lose at least USD 5 million on exactly one day in every 100
Explanation
VaR is a quantile of the loss distribution: losses are expected to exceed it with probability 1 − confidence level. The average loss beyond VaR is expected shortfall, not VaR. VaR is not a maximum loss and gives no guarantee of exact exceedance counts.
