Methodology#
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. SEIC data begins August 1981; values as of August 2026 and refresh daily. Past performance does not predict future returns; not investment advice.
