Baron Durable Advantage Fund declined 9.0% in Q1 2026 versus the S&P 500's 4.3% decline, primarily due to geopolitical tensions from the Iran war that spiked oil to $150 per barrel and reduced rate cut expectations. The underperformance was driven by sector allocation (two-thirds) and stock selection (one-third), with the Fund holding no Energy positions while overweighting Financials. However, the manager views this as creating attractive opportunities, noting portfolio valuations are 12.9% below five-year averages and the correction was driven by multiple contraction rather than fundamental deterioration. The quarter's most significant development was dramatic AI adoption acceleration, with companies like Anthropic adding $21 billion in ARR in one quarter and Amazon AI reaching $15 billion revenue run rate. The manager emphasizes investing in companies with durable competitive advantages like network effects, proprietary data, and manufacturing complexity that remain defensible in the AI era. Top contributors included semiconductor names MPS and TSMC, while mega-cap tech stocks Microsoft, Meta, Amazon, and Alphabet detracted despite strong fundamentals.
Invest in large-cap companies with strong and durable competitive advantages, proven capital allocation track records, high returns on invested capital, and high free cash flow generation that regularly return capital to shareholders through dividends or buybacks.
The manager believes the current geopolitical tension and AI disruption uncertainty have created an attractive buying opportunity for U.S. large cap stocks. Portfolio valuations are 12.9% below five-year averages. The Fund's correction was driven by multiple contraction rather than fundamental deterioration, which bodes well for prospective returns. The manager remains optimistic about prospects of portfolio companies and continues searching for new investment opportunities.

| TICKER | COMMENTARY |
|---|---|
| MPS | Monolithic Power Systems, Inc. (MPS) designs chips that deliver precise, safe, and efficient power to processors, memory, and sensors in electronic systems. Shares rose 21.0% during the quarter following continued robust quarterly results, closing 2025 with full year revenues of $2.8 billion, up 26% year-on-year, while guiding Q1 2026 meaningfully above expectations with revenues of $780 million (at the mid-point) compared to consensus estimates of $738 million. The company is poised to benefit from two major secular trends: AI-driven data center redesigns and automotive electrification. |
| TSM | Taiwan Semiconductor Manufacturing Company Limited (TSMC) shares rose 11.5% during the first quarter, as revenue growth of 20.5% (25.5% in USD) exceeded expectations due to surging demand for AI chips. TSMC dominates the advanced semiconductor foundry market, controlling over 90% share of cutting-edge sub-7 nm nodes that power AI servers, flagship smartphones, and autonomous vehicles. As the ultimate picks-and-shovels provider of the AI era, TSMC remains insulated from the competitive dynamics of the AI chip design ecosystem. |
| CME | CME Group, Inc. operates the world's largest and most diversified derivatives marketplace. Shares rose 10.8% due to higher trading volumes during a period of elevated market volatility. Average daily trading volume rose at a robust 22% pace during the first quarter, reflecting concerns over higher energy prices from the Iran war, persistent inflation, and an uncertain outlook for interest rates. |
| MSFT | Software leader Microsoft Corporation detracted from performance with shares down 22.8% despite reporting slightly better-than-expected revenue, margins, and earnings per share in the quarter, with cloud revenue up 24% year-over-year in constant currency and commercial bookings up 228%, driven by commitments from OpenAI and Anthropic. Azure growth of 38% year-over-year in constant currency was slightly below expectations, reflecting slightly greater capacity allocation to first-party applications over renting out GPUs to external customers in the quarter. |
| META | Shares of Meta Platforms, Inc., the world's largest social network, declined 13.3% in the first quarter. While Meta reported strong quarterly results with 24% year-on-year revenue growth and 41% operating margins, and issued a solid Q1 revenue guidance of 29% year-on-year growth rate at the high end (in constant currency), management guided to full-year 2026 operating expenses above Street expectations, implying a 40% increase year-on-year, and raising concerns that it may be overspending on AI for less clear returns relative to competitors. |
| AMZN | Amazon.com, Inc. is the world's largest retailer and cloud services provider. Shares declined 9.8% during the quarter after the company guided to $200 billion in fiscal year 2026 capital expenditures, above Street expectations. Amazon AI is now at a $15 billion revenue run rate (260x larger than original Amazon Web Services (AWS) at the same point), their combined custom chips business (Graviton, Trainium, and Nitro) is now at a $20 billion ARR, growing triple-digit percentages year-over-year, implying approximately 13% of total AWS revenues. |
| GOOGL | Alphabet Inc. was mentioned as one of the largest detractors with shares declining 8.5%. The manager notes that Alphabet invested early in custom AI accelerators (TPUs) unveiled in 2016 and started autonomous driving project in 2009. Alphabet's TPUs are a huge driver of Google Cloud Platform's growth and Waymo was recently valued at $126 billion. |
| NVDA | NVIDIA Corporation is the Fund's largest holding at 8.3% of net assets. Jensen Huang has led NVIDIA for 33 years since founding it in a Denny's in 1993. The manager views founder-led management that thinks and acts like long-term owners as a key attribute of successful investments. |
| LRCX | During the quarter, the Fund initiated a new position in Lam Research Corporation. Lam is a leading global supplier of semiconductor WFE, specializing in etch, deposition, and clean technologies used in the manufacturing of integrated circuits. The industry is at a key inflection that will disproportionately benefit Lam given its outsized exposure to etch and deposition, the most layer-intensive process steps in chip manufacturing. Lam holds virtually 100% market share in high-bandwidth-memory (HBM) high-aspect-ratio etches required for AI applications. |
| MSCI | The largest addition during the quarter was to MSCI Inc., a leading provider of indices and investment decision support tools. The company reported strong Q4 2025 earnings and management sounded upbeat about the business going forward. MSCI has vast amounts of truly proprietary data and analytics, and nearly everything MSCI sells to customers is proprietary in nature. CEO Henry Fernandez recently said that 'AI is a godsend to us.' |
| WELL | We continued to build our position in the premium senior housing provider, Welltower Inc., which offers both 'offensive' and 'defensive' investment attributes. Welltower owns senior housing properties in some of the best micro-markets with substantial pricing power given the company serves a higher net worth demographic. Several characteristics were on display in the most recent quarter with 20% same-store net operating income year-on-year growth in senior housing and a 28% year-on-year earnings growth. |
