| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year?Market Summary: : The twelve months ended September 30, 2025, reflected a constructive environment for small-cap equities. After a volatile start to the year—driven by renewed tariff concerns and mixed economic data—markets strengthened as inflation moderated and monetary policy turned more supportive. The Federal Reserve lowered rates by 50 basis points in 3Q24, followed by a 25-basis-point cut in December and another in 3Q25 after pausing earlier in the year. These moves, combined with steady employment and resilient consumer spending, created what many described as a “Goldilocks” backdrop—growth that was positive but not inflationary.The Russell 2000 Growth Index gained +13.6%, as participation broadened beyond large-cap technology into cyclical sectors such as Industrials and Financials. While sentiment improved, investors remained attentive to potential headwinds from rising input costs and tariff-related pressures that could weigh on margins in coming quarters. Fund Performance: For the fiscal year, the Nicholas Partners Small Cap Growth Fund returned +14.0% (net) versus +13.6% for the benchmark. Industrials contributed most, supported by holdings aligned with reindustrialization, automation, and defense modernization, while Healthcare benefited from biotechnology and MedTech companies with identifiable catalysts. Energy added through exposure to nuclear-related and alternative-power opportunities. Technology advanced in absolute terms but modestly trailed the benchmark as speculative software and early-stage AI names outperformed the Fund’s emphasis on quality, profitable businesses. Overall, results were driven primarily by stock selection in Industrials and Healthcare, with incremental contribution from Technology exposure tied to AI infrastructure and data connectivity, while Consumer and Real Estate holdings modestly detracted. Positioning and Outlook: Throughout the fiscal year, the Fund’s positioning evolved to capture multi-year growth themes shaped by AI infrastructure buildout, grid modernization, and rising digital-era power demand—areas the team views as durable, secular opportunities.
Industrials increased to roughly 30%, emphasizing automation, defense, and power-grid modernization; Healthcare remained near 20%, focused on biotechnology and MedTech innovators; Technology held close to 20%, anchored in semiconductors, electrical components, and AI-infrastructure enablers; and Energy modestly increased through exposure to nuclear fuel and power-reliability investments. The Fund remained fully invested, maintaining meaningful off-benchmark exposure consistent with its benchmark-aware but not benchmark-constrained approach.
The team believes the environment for small-cap equities remains favorable as inflation pressures ease and monetary policy turns more supportive. Credit spreads near decade lows indicate market confidence in the economic outlook and corporate balance-sheet strength, while fundamentals are regaining influence amid accelerating small-cap earnings growth and valuations that remain near historical lows. Against this backdrop, the team continues to see opportunities in:
The Fund continues to apply Nicholas Partners’ bottom-up, research-driven process, focusing on companies undergoing positive change, with attention to valuation, liquidity, and risk management. |
