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.

Sharpe ratio uses the return of short-term government bills in the same currency as the risk-free rate. The growth chart uses month-end values; drawdowns and volatility use daily closes.
