How the figures are calculated
Total return in the fund’s trading currency, from end-of-day prices with dividends reinvested on the ex-date. The fund’s own ongoing charges are already reflected in its price; trading costs, taxes and currency conversion are not included. Past returns do not predict future returns.
The comparison uses only the months in which both funds have prices, so the figures cover the same period even when one fund is older.
