Methodology. Four Invesco RAFI (£, LSE) UCITS ETFs, compared on a like-for-like basis: PSRW.L (All-World), PSRE.L (Europe), PSRM.L (Emerging Markets), PSRF.L (US). The chart plots each fund's total-return index, all rebased to 100 at 1 Feb 2010 (PSRW's share-class relaunch date); on each ex-dividend date the distribution is treated as reinvested. PSRW's index is built from Yahoo daily close + dividend history; £PSRE/£PSRM/£PSRF from Yahoo adjusted close (dividends reinvested), so all four are directly comparable. Solid lines = total return; white = PSRW raw share price (hidden by default). Data: daily 2010-02-01 → 2026-08-18, Yahoo Finance. Updated 2026-08-18.
