Executive Summary

Alger Spectra Fund Class A shares advanced 0.29% net of fees in the third quarter of 2026, underperforming the Russell 3000 Growth Index return of 0.45%. Year-to-date, the fund has generated a net return of 11.72% compared to 6.37% for the benchmark. Portfolio performance was propelled by relative strength in Consumer Discretionary and Information Technology holdings, whereas Communication Services and Utilities positions detracted. The fund maintained its highest sector exposures in Information Technology and Communication Services, running its largest sector overweight in Information Technology and its largest underweight in Financials. The macroeconomic environment was shaped by rising long-term yields, persistent above-target inflation, and escalating Middle East geopolitical conflict that pushed oil prices past $100 per barrel. In response to persistent inflation risks, the Federal Reserve delivered a 25 basis point rate hike in September, sending the 10-year Treasury yield up 83 basis points over the quarter. While broader equity breadth narrowed sharply, the team reaffirmed its constructive view on enterprise artificial intelligence adoption, differentiating between foundational infrastructure providers, productivity beneficiaries, and legacy business models facing terminal disruption. Key performance contributors included mega-cap technology leaders Microsoft, NVIDIA, and Meta Platforms, alongside a profitable short position in an ad-tech vendor. Performance was dampened by pullbacks in Western Digital, Nebius Group, and SpaceX, alongside an IT consulting short position. Management maintained disciplined long exposure across key AI enablers while actively managing downside via single-stock short positions.

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

72%

CautiousHigh

High Conviction (72%)

Management expresses decisive fundamental belief across its high-conviction holdings, explicitly disclosing sizeable concentrated allocations including NVIDIA at 16.55% and Microsoft at 9.64%. The fund backs these positions with granular operational theses while holding through quarterly volatility, although overall fund diversification and short hedging slightly moderate absolute concentration.

Growth Outlook

55%

BearishBullish

Neutral (55%)

The manager expresses balanced market sentiment, remaining constructive on AI-driven structural secular growth while acknowledging significant headwinds from weak equity market breadth, surging interest rates, and geopolitical turmoil. Persistent inflation and Fed rate hikes present ongoing macro crosscurrents that temper unconstrained bullishness.

Risk Appetite

65%

DefensiveAggressive

Balanced (65%)

Capital remains oriented toward high-beta, growth-focused equity securities and substantial allocations to emerging technology infrastructure. However, total risk appetite is calibrated by active short positions across advertising technology and IT consulting businesses, alongside an underweight in capital-intensive financials.

Capital Deployment

55%

De-riskingDeploying

Net Neutral (55%)

Capital posture remains stable with disciplined long exposure and ongoing short hedging (up to approximately 10% of portfolio value). The team avoided drastic cash raising despite market volatility, choosing to maintain high conviction in core holdings while monitoring funding markets.

Forward Guidance

60%

CautiousExpansionary

Neutral (60%)

The portfolio team conveys a steady deployment stance, expressing confidence in the long-term fundamentals of recent detractors like Western Digital, Nebius, and SpaceX. Rather than de-risking, the team intends to maintain exposure to high-quality growth assets while adhering to disciplined bottom-up stock selection.

Language Signal

65%

BearishBullish

Bullish (65%)

The tone leans constructive when detailing enterprise AI adoption, resilient consumer demand, and corporate earnings strength. This optimism is balanced by clear recognition of macro risks including Middle East oil supply disruptions, shareholder dilution concerns, and narrow market breadth.

Perceived Risk

68%

Low RiskElevated

Elevated Risk (68%)

The commentary explicitly highlights several macro and systemic threats, including the 10-year Treasury yield hitting its highest level since 2007, crude oil topping $100 per barrel due to Middle East conflict, and potential terminal disruption to legacy business models from generative AI.

Opportunity Density

60%

ScarceAbundant

Selective (60%)

The manager identifies compelling opportunities across the emerging AI economy, specifically identifying software productivity tools, independent compute providers, and storage enablers. Nonetheless, opportunity density is described as selective rather than broad, with roughly 60% of S&P 500 stocks declining.

Time Horizon

75%

Short-TermLong-Term

Decade+ (75%)

Investment rationale is explicitly framed around multi-year structural transformations, specifically the durable buildout of artificial intelligence infrastructure and long-term enterprise productivity adoption. Management looks past quarterly multiple contraction and temporary lockup expirations to focus on multi-year compounding.
