Methodology
Investments are assumed made at the chosen month's last trading day close, or that exact day's close when a day is picked. "Dividends reinvested" uses split- and dividend-adjusted closes (a standard total-return approximation; taxes and fees excluded). "Price-only" uses split-adjusted closes. ALNY data begins June 2004; values as of September 2026 and refresh daily. Past performance does not predict future returns; not investment advice.
