Methodology#
Trailing returns measure from the closest close about N years before the latest close (2026-07-24). Cumulative return is the total change over the window; annualized return is the compound annual growth rate (CAGR), shown for windows of a year or more. Total return reinvests dividends (from AON's split- and dividend-adjusted closes); price return excludes them. See the year-by-year returns for the calendar breakdown. Past performance does not predict future returns; not investment advice.
