Unpacking Q2 2026: A Deep Dive into Small Cap Growth Fund's Journey

Fund Performance Overview: A Quarter in Review

The Small Cap Growth Fund concluded the second quarter of 2026 with a notable return of 24%. In comparison, its primary benchmark, the Russell 2000® Growth Index, outperformed slightly with a 26% return for the same period. This marginal difference underscores a competitive yet challenging quarter for the fund.

Factors Influencing Relative Performance

The fund's performance relative to the benchmark was largely impacted by the robust strength observed in higher-beta stocks and companies significantly involved in AI infrastructure. These segments saw substantial gains within the Russell 2000® Growth Index, creating a headwind for the fund that had a different allocation. However, the fund's emphasis on specific earnings quality and future prospects partially mitigated these effects.

Sectoral Contributions and Lagging Areas

On a sector-by-sector analysis, the Information Technology and Materials sectors were the most significant positive contributors to the fund's relative return, showcasing the strength and strategic positioning within these areas. Conversely, the Health Care, Financials, and Energy sectors experienced a drag on performance, indicating areas where the fund's holdings did not keep pace with broader market movements or benchmark components.

Strategic Adjustments and Future Outlook

In light of recent market shifts and the Russell reconstitution, the fund is actively recalibrating its sector exposures. There is a concerted effort to increase allocation to the Biopharma sector. Simultaneously, the fund is prudently reducing positions in holdings that have seen outsized gains and divesting from companies whose market capitalizations now fall outside the benchmark's eligibility criteria, ensuring adherence to its investment mandate.

Macro Trends and Investment Philosophy

The fund's strategic direction is increasingly influenced by several overarching macro trends, including the surge in AI-driven capital expenditure, the ongoing realignment of global supply chains, and a focused approach to capital allocation. These trends are shaping the investment landscape, creating fertile ground for the fund's fundamental, bottom-up investment approach, particularly within the small-cap growth equity space. The fund remains committed to identifying and investing in innovative companies poised for long-term success amidst these evolving dynamics.
