Alger Small Cap Growth Fund Q1 2026 Portfolio Update

Alger Small Cap Growth Fund Class A shares underperformed the Russell 2000 Growth Index in Q1 2026. Top contributors included RBC Bearings, Nebius Group, and Modine Manufacturing, while GeneDx Holdings, Astera Labs, and Planet Fitness were the main detractors. The note is largely a performance attribution update with limited market-moving implications.

Analysis

The performance dispersion suggests this is less a broad small-cap factor call and more a stock-selection regime where earnings durability and index membership effects are doing the heavy lifting. The names that worked are exposed to secular capex or operating leverage, so they can keep outperforming even if the growth factor cools; the loser set looks more vulnerable to multiple compression because it combines subscription/recurring demand with higher sensitivity to sentiment and financing conditions.

Second-order, the biggest opportunity may sit in the adjacent ecosystem rather than the obvious winners. If AI/data-center buildout remains the core end market behind the strongest names, suppliers with cleaner balance sheets and shorter lead times should continue to take share from higher-expectation peers that need flawless execution. Conversely, consumer-facing discretionary growth names are likely to underwrite a much lower terminal multiple if rates stay sticky and job-market data softens, because their demand elasticity is higher than the market typically prices in.

The contrarian risk is that recent winners may already be crowded factor expressions: strong flow can overwhelm fundamentals for a few weeks, but once momentum stalls, upside can mean-revert quickly if management commentary normalizes. For the underperformers, the setup is more asymmetric if there is any guide-up or margin recovery over the next 1-2 quarters; small-cap growth names can re-rate 15-25% on modest beats when positioning is light. The key catalyst window is earnings season and forward-guidance revisions, not macro headlines.

Key Decisions for Investors

• Long RBC / short PLNT for the next 1-2 earnings cycles: prefer industrial/mission-critical demand over consumer discretionary exposure; target 8-12% relative outperformance if growth remains intact, with a stop if PLNT shows same-store acceleration or commentary improves materially.
• Add MOD on pullbacks rather than chasing: use a staged entry over 5-10 trading days, as the name can stay supported by operating leverage and industrial AI/cooling exposure; risk/reward is favorable if the market keeps paying for visible capex beneficiaries.
