Methodology#
Monthly returns are total returns (dividends reinvested), computed from CSGP's split- and dividend-adjusted month-end closes. The table shows the most recent 120 months and the bar chart the most recent 60. See the year-by-year returns for the annual view. Past performance does not predict future returns; not investment advice.
