The Platinum International Technology Fund returned 24% in Q2 2026 as markets rebounded from Iran conflict concerns. The core thesis centers on investing in technology companies with unique, hard-to-replicate capabilities that can sustain high margins and returns on invested capital. Semiconductor capital equipment holdings drove strong performance, with KLA and Lam Research doubling as markets priced in capacity expansions at foundries and memory companies. The fund added positions in the NAND supply chain (Kokusai Electric, Kioxia) and datacentre power infrastructure (ASTA Energy, AT&S). Industrial automation holdings (Keyence, FANUC) rose over 30% on strong results. Defense holdings underperformed following the Iran ceasefire, with Rheinmetall exited on risk management grounds. The manager made several space-related investments, viewing it as a growth industry driven by defense and telecommunications, while avoiding direct SpaceX exposure due to concerns about its xAI subsidiary competing in the contested AI datacentre segment. The fund trimmed several positions and initiated shorts on legacy telcos vulnerable to Starlink competition. Looking forward, the manager remains positive on AI infrastructure while focusing on overlooked high-quality businesses.
The fund focuses on high-quality technology businesses with unique or differentiated capabilities that are hard to replicate, enabling them to grow in line with or faster than their markets while sustaining high margins and high return on invested capital. The manager is positioned in semiconductor capital equipment benefiting from capacity expansions, industrial automation, AI infrastructure providers, space ecosystem opportunities, and datacentre power infrastructure, while avoiding direct exposure to highly competitive AI model development and maintaining selective defense exposure for long-term growth.
Investors remain enthusiastic about AI infrastructure spending and the manager is happy with current AI exposure. The manager is focusing on parts of the market being ignored by investors, specifically high-quality businesses that could benefit from more use of AI and from continued development in AI technology, as well as high-quality businesses whose growth prospects are unlikely to be affected by AI. The manager sees space as a new growth industry with opportunities in defense and telecommunications, though remains cautious about certain segments like frontier AI models and some space competitors.

Lead Portfolio Manager
Douglas Isles
Managing Partner
Moderate Conviction Bullish
Market Conviction
The fund demonstrates moderate-high conviction through concentrated positioning with top 10 holdings representing significant portfolio weight (TSMC 7.8%, NVDA 6.0%, KLA 4.7%, AMD 4.5%). The manager provides specific position sizing for new additions (Kokusai Electric 2.5%, ASTA Energy 3%, AT&S 2%, Kioxia 2%) and explains detailed investment theses with falsifiable catalysts (NAND supply tightening, transformer demand growth 15-20% annually, substrate undersupply). The letter includes multi-page analysis of space opportunity with specific competitive dynamics. However, the fund maintains 10+ named positions with some hedging through shorts and trims, and acknowledges uncertainty in areas like AI model competition. The explanation is detailed but stops short of extreme concentration or indefinite hold language. Score: 0.68 (high conviction with concentrated positions and clear theses, but diversified enough and with some hedging to not reach 0.75+).
Growth Outlook
Manager sees more favorable setup after selloff but acknowledges geopolitical uncertainty from Iran conflict. Optimistic about structural technology trends but cautious on near-term volatility.
Risk Appetite
High portfolio turnover with major repositioning shows active risk-taking. Moved from software to physical technology enablers. Maintains concentrated exposure to structural growth themes.
Capital Deployment
The fund added six new positions during the quarter (Kokusai Electric 2.5%, Kioxia 2%, ASTA Energy 3%, AT&S 2%, Filtronic 0.5%, Echostar 1.5%) totaling approximately 11.5% of portfolio, while also initiating short positions. The manager trimmed five positions (Broadcom, Siemens Energy, GE Vernova, Vertiv, Aixtron) and exited two (Microsoft, Rheinmetall). No cash level data is provided, but the activity suggests capital rotation with selective net deployment. The additions appear larger than the trims based on position sizing disclosed. Score: +0.45 (moderate deployment through rotation with net positive bias, but without cash data cannot confirm significant net deployment).
Forward Guidance
Manager expects better returns from current positioning in quality companies at reasonable valuations. Positive on structural trends but measured in deployment approach.
Language Signal
The letter contains balanced directional language. Bullish language includes: growth opportunity (space, defense), performed well (semiconductors, automation), attractive (transformer demand), unique capabilities (SpaceX), profitability will improve (NAND), and happy with AI exposure. Bearish language includes: cautious about (SpaceX/xAI exposure), underperformed (defense), concerns (AI competition), vulnerable (legacy telcos), dubious claims (space competitors), and fierce competition (frontier models). The language is more bullish than bearish overall but remains balanced with specific concerns noted. Score: +0.50 (more bullish than bearish, but balanced).
Perceived Risk
Manager identifies multiple specific risks including AI software disruption, geopolitical tensions, capacity constraints, and currency headwinds. Detailed discussion of structural threats to software business models.
Opportunity Density
The manager sees opportunities across multiple areas: NAND supply chain (two new positions), datacentre power infrastructure (ASTA Energy, AT&S), space ecosystem (three positions added), and identifies overlooked high-quality businesses affected by AI. The letter describes space as a new growth industry with multiple use cases and discusses specific supply-demand imbalances (substrates, transformers, NAND). The manager also identifies short opportunities in legacy telcos and overvalued space competitors. The tone suggests a rich opportunity set across semiconductors, infrastructure, and emerging themes, though selectivity is emphasized. Score: 0.72 (selective opportunities across defined areas with multiple new positions opened, but emphasis on selectivity rather than abundance).
Time Horizon
The manager explicitly states defense holdings are viewed as a long-term growth opportunity rather than a short-term capex play, suggesting multi-year patience. The space analysis discusses multi-year buildout of Starlink constellation and future V3 satellite deployment with no urgency. The ASTA Energy thesis is based on 15-20% annual growth over the next five years with long-term supply agreements. However, the letter also discusses near-term catalysts like Q1 results for automation holdings, roadmap transitions for NAND, and next year supply dynamics for substrates. The fund structure is a standard mutual fund with quarterly reporting, not permanent capital. The balance suggests a 2-4 year investment horizon with some catalyst dependency. Score: 0.68 (multi-year thesis with some catalyst dependency, holds through volatility but watches milestones).
