How it has done
IWR share class · total returns with dividends reinvested
Volatility over the last 12 months: 10.69%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
