Return-based risk computed in the open analytics core (quantlib.risk) from 116 daily returns (full history), annualized at 252/yr. Click any metric for its methodology.

Volatility & risk-adjusted return

vs S&P 500 · monthly, same window (6 months)

Only 6 paired monthly returns in this window (needs ≥ 12) — beta, correlation and capture are suppressed rather than estimated from too few points.

Drawdown

Trailing returns · price return

Price-return basis — dividends aren't included for this symbol yet. Re-pull prices to populate the adjusted close and switch to total return.

Return distribution

Volatility (annualized %, right) and Sharpe (ratio, left), each over a trailing 63-period window from quantlib.performance.rolling.

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 8). Lengths are in trading periods; an ongoing episode has not yet reclaimed its prior peak. The deepest episode equals the maximum drawdown above.

Notes

• returns: price-return basis — no adjusted close is stored for this symbol, so dividends are not included (re-pull prices to enable total return)
• benchmark: only 6 paired monthly returns in the window (< 12) — beta/correlation/capture suppressed
