The Optimum International Fund returned 16.74% net in 2Q2026, outperforming the MSCI ACWI ex USA Index which returned 14.49%. The quarter was marked by extreme volatility driven by geopolitical developments and energy price swings. Early weakness stemmed from the Iran conflict pushing Brent crude above $120, but sentiment reversed sharply mid-quarter following a US-Iran ceasefire that reopened the Strait of Hormuz. Technology led sector returns by a wide margin on resilient AI and semiconductor demand, with South Korea's KOSPI surging over 66% powered by SK Hynix and Samsung Electronics. Energy was the weakest sector as oil retreated. The Fund's overweight to semiconductors contributed significantly to outperformance, while energy exposure detracted. Central banks across Europe and Asia tightened policy to combat fuel-driven inflation and defend currencies. Key risks include technology valuations, energy price volatility, and central bank policy uncertainty. The durability of AI demand remains a critical driver for future performance.
The Fund is positioned to capture international equity opportunities across developed and emerging markets outside the US, with dual sub-advisors providing complementary approaches to capitalize on regional market dynamics and secular growth themes.
Looking ahead, inflation, energy prices, central bank policy, UK political developments, and the durability of the AI investment theme remain key drivers for European markets. For Asian markets, inflation, energy prices, central bank policy, and the durability of the AI theme are identified as key drivers going forward.

Market Conviction
The Fund operates with a dual sub-advisor structure managing a diversified international portfolio. Only two individual companies are named (SK Hynix and Samsung Electronics) and only in the context of explaining index performance, not as Fund positions. Discussion focuses on broad sector allocations (overweight semiconductors, overweight energy) and regional market commentary rather than specific holdings with sizing. The letter is primarily descriptive of market conditions and aggregate sector performance. Multiple scenarios and risks are presented without a clear base case thesis. This is a diversified, multi-manager approach with limited specificity on individual conviction positions.
Growth Outlook
Market outlook remains above average conviction: The Optimum International Fund advanced 3.26% in 4Q2025 but lagged behind its benchmark, as outperformance in the Acadian sleeve was offset by underperformance in the growth-tilted...
Risk Appetite
Risk appetite posture is above average conviction: The Optimum International Fund advanced 3.26% in 4Q2025 but lagged behind its benchmark, as outperformance in the Acadian sleeve was offset by underperformance in the growth-tilted...
Capital Deployment
No cash level changes are reported. The letter describes maintaining overweight positions in semiconductors and energy throughout the quarter. There is no evidence of net new capital deployment or de-risking. The discussion focuses on how existing positions performed rather than changes in exposure levels. This represents capital rotation and position maintenance, not net deployment or withdrawal. Score reflects minimal net activity.
Forward Guidance

Language Signal
Language includes positive terms like 'strong gains,' 'robust demand,' 'resilient,' 'fresh all-time high,' and 'record highs.' However, this is balanced by risk language including 'volatility,' 'concerns,' 'turmoil,' 'lagged,' 'weakest sector,' 'jittery,' 'sharp selloffs,' and 'strained economy.' The letter dedicates substantial space to risks and uncertainties. Net balance leans mildly positive but is far from overwhelmingly bullish.
Perceived Risk
Perceived risk level is evaluated as above average conviction. The Optimum International Fund advanced 3.26% in 4Q2025 but lagged behind its benchmark, as outperformance in the Acadian sleeve was offset by underperformance in the growth-tilted...
Opportunity Density
The letter describes selective opportunities concentrated in specific areas. Technology and semiconductors offered strong opportunities with 'resilient demand' and drove significant outperformance. However, the characterization is of uneven sector returns with clear winners (technology) and clear laggards (energy, autos). The forward outlook emphasizes watching multiple factors rather than describing a broad opportunity set. This suggests selective rather than abundant opportunities, with clear pockets of strength but not widespread attractiveness.
Time Horizon
The letter focuses on quarterly performance and near-term catalysts (ceasefire impact, central bank meetings, earnings outlooks). Forward outlook emphasizes monitoring ongoing developments in inflation, energy prices, and policy. No explicit multi-year thesis is articulated. The discussion of AI durability as a 'key driver' suggests awareness of medium-term themes, but the emphasis is on quarterly dynamics and near-term market drivers. This is consistent with a typical public equities fund with 1-3 year investment horizons rather than permanent capital or decade-plus positioning.
