Summary
In its second‑quarter 2026 investor letter, Fred Alger Management’s Alger Capital Appreciation Fund painted a picture of a resurgent U.S. equity market. The S&P 500 Index climbed 15.2% during the quarter, driven by a thaw in geopolitical tensions and rapid technological progress. Those macro tailwinds gave a lift to the Information Technology and Industrials sectors, whereas Energy and Utilities lagged amid falling oil and gas prices. The fund’s outlook remained optimistic about artificial intelligence, noting that while AI disruption is a frequent topic of discussion, the real opportunity lies in companies that are adopting the technology as it moves into its “agentic” phase—where AI systems act autonomously to perform complex tasks.
Against this backdrop, the Alger Capital Appreciation Fund’s Class A shares outperformed the Russell 1000 Growth Index for the quarter. The outperformance was principally fueled by strong showings in the Information Technology and Communication Services buckets, which benefited from heightened demand for cloud computing, semiconductor advancements, and digital communication tools. Conversely, the Industrials and Financials sectors detracted from overall performance, reflecting softer capital‑expenditure plans and a more cautious lending environment.
The letter encouraged readers to examine the fund’s top five holdings to see where its conviction lies, although the specific names were not reproduced in the excerpt. Among the highlighted positions, Nebius Group N.V. (NASDAQ:NBIS) stood out as a notable contributor to the fund’s quarterly results. Nebius describes itself as a full‑stack AI‑infrastructure provider, delivering GPU‑accelerated cloud computing alongside proprietary software and purpose‑built data‑center designs to help enterprises train and deploy large‑scale AI models. The fund’s commentary emphasized the company’s vertically integrated approach, which it argues yields superior performance and lower operating costs compared with traditional GPU‑cloud providers.
Nebius’s market metrics underscored its rapid ascent. On July 15, 2026, the stock closed at $199.51 per share. Although it experienced a one‑month pullback of –30.41%, the shares had gained an impressive 271.60% over the preceding 52 weeks, reflecting strong investor enthusiasm for its growth story. The company’s market capitalization stood at roughly $50.65 billion. Financially, Nebius reported a staggering 684% year‑over‑year increase in Q1 2026 revenue, reaching $399 million—a figure that illustrates the surging demand for AI‑focused compute power.
The fund elaborated on why Nebius contributed positively to performance. Better‑than‑expected revenues, propelled by heightened demand for AI computing power, were a primary driver. In addition, Nebius announced the development of a 1.2‑gigawatt data‑center campus, signaling a major expansion of its capacity to serve large‑scale AI workloads. A strategic acquisition aimed at strengthening the company’s model‑optimization capabilities further bolstered its competitive edge.
While Alger acknowledges Nebius’s potential, the letter also cautions that other AI‑related equities may present a more attractive risk‑reward profile. The fund points to stocks that could benefit disproportionately from Trump‑era tariffs and the broader onshoring trend, suggesting they might deliver greater upside with comparatively lower downside risk.
