Tail risk — VaR / CVaR methodology →

Signed daily quantiles (a 5% loss is −5%); CVaR ≤ VaR ≤ 0. The Cornish-Fisher row adjusts the Gaussian VaR for skewness and excess kurtosis (fat tails), so it has no historical counterpart.

Drawdown episodes methodology →

Each peak-to-recovery underwater episode, worst depth first (top 10). Lengths are in trading periods; an ongoing episode has not yet reclaimed its prior peak. The deepest episode equals the maximum drawdown above.
