Methodology
One month is 21 trading sessions, plus the September 17 prior-close baseline. Ending mark: October 16, 2026, 16:00 ET. Return is last marked portfolio value / first marked portfolio value − 1, including cash. Risk uses regular-session daily closes. Drawdown is the largest peak-to-trough decline; volatility is annualized using √252. SPY comparison is a percentage-point difference, not an additional ranking input.
