Portfolio VaR
Portfolio Value at Risk, or VaR, is a statistical measure used to quantify the maximum potential loss of a portfolio over a specific time horizon at a given confidence level. For crypto-derivative traders, VaR provides a single number representing the downside risk under normal market conditions.
It integrates the volatility of individual assets and their correlations to estimate how much capital might be lost during a market downturn. While useful, VaR often fails to capture tail risk or extreme black swan events common in digital asset markets.
Consequently, many institutions supplement VaR with stress testing to understand how the portfolio would perform during liquidity crises or exchange failures. It is a vital risk management metric for ensuring that leveraged positions do not exceed the firm's risk appetite.
