"Positioned aggressively in secular AI hardware, optical networking, and bioprocessing leaders, capitalizing on mid-year pullbacks to scale high-conviction compounders while navigating energy-driven inflation and tighter monetary policy."

Executive Summary

Janus Henderson Forty Fund delivered a net return of 2.25% in the third quarter of 2026, outperforming the Russell 1000 Growth Index return of 0.92% by 133 basis points, while slightly trailing the broad S&P 500 Index return of 2.30%. On a year-to-date basis, the fund generated a net return of 6.78%, outpacing its growth benchmark's 6.30% gain. Relative outperformance was primarily driven by effective stock selection within the consumer discretionary sector, which offset moderate performance drag originating from selections across healthcare holdings. The fund maintained its focused, non-diversified portfolio structure, with the top ten equity holdings comprising 56.10% of total fund assets. The macroeconomic environment during the quarter was defined by renewed financial volatility, driven by Middle East geopolitical conflicts that drove crude oil prices higher and reignited broader inflationary anxieties. In response, the Federal Reserve initiated a 25 basis point policy rate hike in September, representing its first tightening measure since 2023. Concurrently, investor sentiment around artificial intelligence fluctuated between long-term enthusiasm and skepticism regarding hyperscaler capital deployment returns. Nevertheless, AI-linked fundamentals remained strong, generating the predominant share of S&P 500 earnings growth, while power shortages and physical infrastructure constraints became central operating themes. Portfolio activity was highlighted by opportunistic capital deployment, including taking advantage of the July equity pullback to materially expand the fund's holding in optical networking supplier Lumentum Holdings. Life sciences leader Danaher contributed positively as biopharma inventory destocking reversed into order reacceleration. Conversely, aerospace component supplier Howmet Aerospace and semiconductor equipment leader Lam Research experienced relative detractions due to insourcing concerns and digestion of AI capex timing, though fundamental demand trajectories in both businesses remain robust.
