Methodology#

A buy is made at the start date's close, or the next session's when the market was closed that day, and valued at the end date's close; a monthly or yearly plan buys on the same day of each month or year. "Dividends reinvested" uses split- and dividend-adjusted closes (a standard total-return approximation; taxes and fees excluded). "Price-only" uses split-adjusted closes. MSI data begins January 3, 1977; values as of October 27, 2026 and refresh daily. The ranking compares month-end to month-end periods. Past performance does not predict future returns; not investment advice.
