Fund profile
As filed in the prospectus · 2026 Q1
The fund seeks long-term capital growth.
The fund invests at least 80% of its net assets in small-cap stocks—those with market capitalizations not exceeding approximately $26.0 billion, the size of the largest company in the Russell 2000 Growth Index as of December 31, 2025. Portfolio managers select stocks by identifying companies with earnings and revenues growing at an accelerating pace, including those showing improving negative growth rates and expected future acceleration, and may also favor stocks demonstrating relative price strength against peers. The fund may engage in active and frequent trading, which can increase transaction costs and capital gains distributions. Foreign securities may be held when they meet the managers' selection criteria.

Net is what a holder pays after the adviser's contractual waiver; gross is before it. A waiver can expire.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Stocks | 99.14% |
| Cash & short-term | 1.62% |
| Derivatives | -0.02% |
The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.
Derivatives are shown at market value, not notional exposure.
Sector allocation
The same holdings as Allocation above, grouped by market sector instead of asset type · as of 2026 Q2
| Industrials | 23.9% |
| Health Care | 22.4% |
| Information Technology | 21.8% |
| Financials | 8.3% |
| 10 smaller | 23.5% |
Government, Securitized and Cash are non-corporate buckets; International is foreign holdings we don’t sector-classify, and Other is the residual (held funds, unresolved names).
Portfolio growth profile
How much of the fund’s stock holdings are in fast-growing companies · as of 2026 Q2
Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.

These classes hold the same portfolio, so the 12.35pp spread over 5 years is the cost difference between them — roughly 2.47pp a year — not a difference in what they own.
