Baron Fifth Avenue Growth Fund: Latest Insights and Commentary

After selling off in March due to the U.S.-Iran conflict and disruptions in the Strait of Hormuz, U.S. equities rallied to new record highs during the second quarter, with most of the gains coming in April and May. Given narrow market breadth and concentrated position sizes in recent years, the gap in performance between the market cap-weighted S&P 500 Index and the equal-weighted version has reached extremes not seen since the dotcom bubble era (based on rolling three-year results). 

U.S. stocks saw a comeback after ending the prior quarter slightly down. The AI secular growth narrative was the principal driver of market returns, overshadowing uncertainty about a potential resolution to the U.S.-Iran conflict, shifting Federal Reserve rate expectations, and depressed consumer sentiment from high living costs, persistent inflation, and elevated borrowing rates. 

The S&P 500 posted one of its strongest quarterly profit prints in five years, thanks largely to the Magnificent Seven cohort, which reported blended earnings growth in excess of 60% (versus low double digits for other constituents in the Index). The other contributors were primarily Information Technology (IT) stocks—specifically companies that are perceived to be direct beneficiaries of AI capital spending and electrification and what the market has come to call “AI winners." 

Looking ahead, we remain focused on well-managed companies with durable competitive advantages and attractive growth prospects. While macroeconomic and policy uncertainty persist, we believe maintaining a disciplined, long-term perspective and emphasizing company fundamentals will be essential to navigating the evolving landscape.

CONTRIBUTORS

• Space Exploration Technologies Corp. (SpaceX) develops and launches advanced rockets, satellites, and spacecraft, with the long-term goal of making humanity multi-planetary. Shares rose as the company successfully completed the largest initial public offering in history, raising more than $85 billion. The proceeds are expected to accelerate growth across massive addressable markets, such as connectivity, launch, terrestrial and space infrastructure, and AI. Fundamental momentum was further reinforced by landmark compute hosting deals totaling tens of billions of dollars annually, including agreements with market leaders Anthropic and Google. SpaceX also announced its acquisition of Cursor, a premier enterprise AI-powered coding platform. Integrating Cursor’s technology, talent, and customer base provides another strategic stepping stone into the vast opportunities within AI applications and agentic systems. Lastly, the company conducted a successful test flight of the latest version of Starship, demonstrating meaningful advancements in rapid and full reusability. We believe these developments support sustained long-term revenue and profit growth well beyond current levels.
• Taiwan Semiconductor Manufacturing Company Limited (TSMC) is the world's largest contract chipmaker and the leading manufacturer of advanced logic semiconductors used in modern AI accelerators. Shares rose during the quarter as investors increasingly recognized that TSMC, rather than any individual chip designer, sits at the center of the AI supply chain. High-performance computing now represents the majority of TSMC's business. AI demand is consuming so much leading-edge capacity that smartphone and PC production is increasingly shifting to older technology nodes, reversing a dynamic that defined the foundry industry for much of the past decade. Management also raised its full-year outlook and increased capital spending to support demand that remains well above available supply. We retain long-term conviction in TSMC and view its leading-edge manufacturing monopoly, pricing power, and 2-nanometer technology roadmap as durable advantages that support multi-year earnings power.
• Observability and cloud monitoring platform Datadog, Inc. contributed to performance during the quarter after reporting its strongest results in years. Revenue accelerated to 32% year-over-year growth, marking the fourth consecutive quarter of acceleration and meaningfully exceeding consensus estimates. Operating margins and free cash flow also surpassed expectations. Management raised full-year revenue guidance by roughly $240 million against a $50 million beat, with next-quarter guidance implying continued strength. Critically, the strength was broad-based: non-AI core customer revenue growth accelerated into the mid-20% range at scale, while Datadog's AI-native customer cohort diversified and expanded to 22 customers spending more than $1 million annually. Net revenue retention reaccelerated into the low-120% range, and unit economics remained best-in-class with 80% gross margins and high-20% free cash flow margins. We view observability as a structural beneficiary of the AI buildout through cloud migration, faster application deployment, and an increasingly complex technology stack. These broadening growth drivers reinforce our conviction in the long-term thesis.

DETRACTORS

• Intuitive Surgical, Inc. sells robotic-assisted surgical systems. Shares declined after the company's first-quarter U.S. system placements came in below investor expectations. Medical device stocks also broadly underperformed the market amid concerns that health care utilization trends could decelerate following the expiration of Affordable Care Act subsidies. Concerns were further compounded by the potential impact of Medicaid work requirements expected to take effect in 2027. Despite these headwinds, we believe Intuitive can continue to grow revenue at a mid-teens rate for many years and remain positive on the company's long-term growth outlook.
• Shopify Inc., a leading global commerce platform serving merchants across online and offline channels, detracted from performance in the second quarter. The decline was driven by multiple compression rather than any deterioration in the underlying business or fundamental outlook. Shopify continued to post healthy growth in gross merchandise volume and revenue. Instead, the pressure reflected investor concerns about the company's long-term positioning in a future state of e-commerce that may rely more heavily on AI-driven applications than traditional websites. We view those concerns as misplaced and increasingly see Shopify as an AI winner. Two decades of proprietary data across millions of merchants provide Shopify with a strong foundation for AI tools that improve merchant outcomes. Recent product releases also embed the platform more deeply within the emerging agentic commerce ecosystem while creating new monetization opportunities. We continue to believe that Shopify is the category-defining platform for modern commerce, benefiting from durable secular growth in digital retail, an expanding suite of merchant solutions, improving free cash flow, and a widening competitive moat.
• Coupang, Inc., Korea's largest e-commerce platform, detracted from performance. The stock came under pressure following first-quarter results, where in-line revenue was overshadowed by softer second-quarter guidance as capacity and supply chain investments made ahead of Coupang’s 2025 data breach weighed on margins while customer volumes recovered. Sentiment was further weighed down by a record KRW 624.7 billion (about US$430 million) privacy fine stemming from an investigation into the breach, while a rotation of fast money into AI and semiconductor names added to the weakness. Despite these headwinds, our conviction remains intact. We view the margin pressure as temporary, and the fine, a monetary penalty rather than an operational restriction, removes a key overhang and reinforces our belief that the breach does not reflect a structural loss of share. By the end of April, Coupang recovered roughly 80% of the post-breach decline in WOW Membership (its paid subscription program), with returning members resuming prior spending levels. We continue to view Coupang as a competitively advantaged e-commerce business gaining share in its core market while scaling Taiwan operations.
