Executive Summary

Alger Weatherbie Specialized Growth Fund (Class A shares without sales charge) returned -16.00% net of fees in the third quarter of 2026, underperforming its benchmark, the Russell 2500 Growth Index, which returned -10.35%. Year-to-date net performance stands at -3.59% net of fees compared to 7.28% for the benchmark. The portfolio maintained its largest absolute sector weights in Industrials and Health Care, with Industrials representing the primary sector overweight and Information Technology serving as the largest sector underweight. Portfolio breadth mirrored broader market strain, where roughly 60% of S&P 500 equities finished negative despite large-cap index gains. The investment environment was dominated by crosscurrents including interest rates surging across the curve, the 10-year Treasury yield jumping 83 basis points, and the Federal Reserve increasing rates by 25 basis points in September amid sticky inflation and rising oil prices above $100 per barrel. Skepticism emerged regarding the heavy capital spending required for AI infrastructure and its return on investment. The managers emphasize disciplined fundamental research, noting that while artificial intelligence offers expanding productivity opportunities beyond core hardware suppliers, it concurrently threatens established business models and traditional value metrics. Performance attribution was shaped by positive contributions from Natera (Signatera testing adoption), Impinj (robust RFID demand and supply-chain market share gains), and Hamilton Lane (evergreen fund asset expansion and performance income). Conversely, performance detraction was led by Cardinal Infrastructure due to rising project and subcontracting costs, VSE Corporation following a broader valuation rotation and acquisition integration overhang, and Casella Waste Systems amid elevated fuel expenses and acquisition margin dilution.

Institutional Meta Strategy

Meta Strategy Gauges

Algorithmic conviction, macroeconomic posture, and risk appetite signals extracted from this quarterly letter with qualitative explanations.

Signal Matrix

Market Conviction

65%

CautiousHigh

Moderate (65%)

The portfolio maintains moderate-to-high conviction across approximately 50 holdings, providing explicit portfolio weightings ranging between 1.65% and 5.49% for discussed positions. Management demonstrates clear willingness to look through near-term margin compressions in names like Casella Waste Systems and VSE Corporation. However, the presence of 50 holdings and benchmark-aware positioning keeps conviction below concentrated mandate levels.

Growth Outlook

55%

BearishBullish

Neutral (55%)

The managers view AI-driven productivity and select SMID-cap compounders favorably, but express clear caution regarding weak market breadth where 60% of S&P 500 stocks declined. Elevated interest rates, renewed Middle East conflict, and oil exceeding $100 per barrel balance their growth optimism.

Risk Appetite

55%

DefensiveAggressive

Balanced (55%)

Positioning remains fully invested with an active growth stance, overweighted in Industrials and Health Care while holding underweight exposure in Information Technology. While capital remains deployed in cyclical growth compounders, heightened scrutiny on AI spending and elevated rate pressures prevent aggressive risk-taking.

Capital Deployment

50%

De-riskingDeploying

Net Neutral (50%)

Perceived Risk

65%

Low RiskElevated

Elevated Risk (65%)

Opportunity Density

60%

ScarceAbundant

Selective (60%)

Opportunities are viewed as compelling but selective, requiring rigorous stock selection as AI threatens established business models and broader market breadth remains narrow.

Time Horizon

Decade+ (70%)

The commentary reflects a multi-year investment horizon, evident in the manager's commitment to holding compounders through temporary acquisition integrations and quarterly margin noise.
