Total return and risk statistics by fund. Each row is one fund; each column is one period or statistic.
Total return with all distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date), split-adjusted, as of September 4, 2026. YTD and 1Y are cumulative; windows of one year or longer are annualized. “Since Oct 2015” measures every fund from October 12, 2015 — the youngest fund's first trading day — so all funds share one comparison window. Volatility is the annualized standard deviation of daily total returns over the trailing 3 years. Sharpe and Sortino divide the annualized return in excess of the risk-free rate by, respectively, that volatility and the downside deviation (both over the trailing 3 years) — higher is better. Max drawdown is the largest peak-to-trough total-return decline over the same window — shallower is better.
