Investments are assumed made at the first trading day's close of the chosen year. "Dividends reinvested" uses split- and dividend-adjusted closes (a standard total-return approximation; taxes and fees excluded). "Price-only" uses split-adjusted closes. DXCM data begins April 2005; values as of July 2026 and refresh daily. Past performance does not predict future returns; not investment advice.
