The fund seeks to provide long-term capital growth by investing primarily in the common stocks of mid-cap growth companies.
The fund invests at least 80% of assets in common stocks of mid-cap growth companies identified through bottom-up fundamental analysis and top-down quantitative screening, targeting firms with consistent revenue and earnings growth, capable management, competitive advantages, and attractive valuations relative to growth rates. Mid-cap status is determined by membership in the Russell Midcap Growth Index or by market capitalization alignment with Russell Midcap, MSCI USA Mid Cap, or MSCI World Mid Cap indexes, currently ranging from $1.8 billion to $98 billion. The fund maintains broad diversification across holdings and may concentrate meaningfully in individual economic sectors at times.

How it has done
PRDMX share class · total returns with dividends reinvested
Volatility over the last 12 months: 12.21%. 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 2 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.84% | +9.48% | +61.85% | +43.56% | -13.12% | |
| 0.67% | +9.65% | +62.70% | +44.87% | -13.08% |
These classes hold the same portfolio, so the 1.31pp spread over 5 years is the cost difference between them — roughly 0.26pp a year — not a difference in what they own.
