How it has done
PREIX share class · total returns with dividends reinvested
Volatility over the last 12 months: 13.12%. 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.
The 3 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.18% | +29.54% | +87.76% | +92.03% | -8.31% | |
| 0.05% | +29.70% | +88.48% | +93.19% | -8.26% | |
| 0.00% | +29.74% | +88.76% | +93.72% | -8.26% |
These classes hold the same portfolio, so the 1.69pp spread over 5 years is the cost difference between them — roughly 0.34pp a year — not a difference in what they own.
