“Monolithic Power Systems designs analog power-management semiconductors used across data center, communications and industrial applications. The company delivered another strong quarter, supported by growing demand across AI data centers, including compute, optical networking and other rack infrastructure. However, as data center power architectures evolve toward 800-volt direct current, we see greater uncertainty regarding Monolithic’s longer-term market share amid increased competition and its lack of captive supply of silicon carbide and gallium nitride. We exited the position to consolidate our AI infrastructure exposure into higher-conviction opportunities.”

“In July, a major technical event severely pressured AI-infrastructure stocks when a large, AI-focused hedge fund operating with significant leverage was forced to liquidate much of its equity book. The semiconductor ETF, which more than doubled during the first half of the year, fell by more than 25% from end of June through late July. During this drawdown, we added to our positions in Marvell Technology, Inc (MRVL), Monolithic Power Systems Inc (MPWR), NVIDIA Corp. (NVDA), and Taiwan Semiconductor Manufacturing Co. (TSM), all of which subsequently delivered strong quarterly results.”

“Monolithic Power Systems: charging ahead of Texas Instruments in power management. Texas Instruments, credited with inventing the integrated circuit, is a global semiconductor leader and the dominant supplier of analogue chips – devices that convert real-world signals such as sound, temperature or power into digital data. These chips are essential in automotive, industrial and data centre applications, and their importance continues to rise as the need to sense, manage and digitise data expands. Where Texas Instruments offers breadth across the analogue market, Monolithic Power Systems (MPS) offers a more focused play on the fastest-growing corner: power management for AI servers, EV powertrains and advanced industrial systems.”

“Despite the broad sell-off among large-cap growth stocks during the first quarter, three portfolio holdings demonstrated double-digit price appreciation – all within the semiconductor area. Consensus spend expectations for data center infrastructure continue to expand rapidly, particularly among the hyperscalers. During the first quarter of 2026, consensus estimates for 2026 and 2027 capital expenditures among Amazon (AMZN), Microsoft (MSFT), Meta (META), Alphabet (GOOGL) and Oracle(ORCL) cumulatively increased by 25% and 23% respectively, largely to support data center demand – inclusive of chips and related equipment. Taiwan Semiconductor Manufacturing Co (TSM), one of the world’s leading contract chip manufacturers and our largest active weight in the portfolio, saw both its 2026 and 2027 consensus EPS estimates climb by 15% during the first quarter driven by favorable management guidance and fundamental strength in its business. Marvell Technology (MRVL), which designs chips focused on data infrastructure including networking, data centers and custom silicon, also experienced meaningful positive revisions to 2026 and 2027 EPS consensus estimates on the back of management’s favorable outlook. In addition, at the end of the first quarter NVIDIA (NVDA) announced a $2 billion investment in the company, along with a strategic partnership focused on AI infrastructure, validating Marvell Technology’s role in next-gen AI data centers. Lastly, Monolithic Power Systems Inc (MPWR), which designs power management semiconductors that regulate and deliver electricity efficiently, experienced a roughly 5% increase in both 2026 and 2027 EPS consensus estimates during the first quarter, as a function of increasing visibility and backlog length.”
