Performance through Oct 14, 2026. Price and NAV returns are simple changes; total returns reinvest each distribution at the series value on its ex-date (first observation on/after). Periods of one year or less are cumulative; longer periods are annualised. Series are built from unadjusted prices plus the distribution record so no distribution is counted twice. Corporate actions: the vendor price series is split-adjusted; rights offerings and mergers are not restated — check Corporate Actions.

Market-price and NAV volatility are different quantities and are never mixed. NAV volatility for funds holding stale-marked or illiquid assets can understate economic risk.
