Value at Risk (VaR) 95% and 99%: practical guide

What VaR 95% and 99% mean

Value at Risk estimates the loss threshold that should not be exceeded over a chosen time horizon at a given confidence level.

$VaR_c = -Q_{1-c}(R)$

Example

If daily VaR 95% is 2.1% and VaR 99% is 3.4% on a $100,000 portfolio:

  • VaR 95% is about $2,100
  • VaR 99% is about $3,400

Historical vs parametric VaR

  • Historical VaR: uses empirical return quantiles.
  • Parametric VaR: uses distribution assumptions (often normal) with mean and volatility.

Historical is often more realistic in changing markets; parametric is faster for repeated scenarios.

Key limits

VaR does not describe the average loss beyond the threshold and can underestimate fat-tail events. Combine VaR with drawdown and CVaR analysis.
