Janus Henderson Investors has reported its fourth-quarter 2025 performance for the Global Sustainable Equity Fund, revealing a challenging investment landscape despite a broader uptick in global equity markets. The firm noted that a favorable economic environment, bolstered by supportive monetary policies and momentum in artificial intelligence (AI) and electrification, led many indices to reach new all-time highs. However, the fund returned -1.72% during the quarter, lagging behind the MSCI World Index, which gained 3.12%. The report indicates that stock selection in the healthcare sector and a reduced allocation to real estate positively influenced relative performance, while selections in industrials and financials detracted from results.
Among the companies highlighted in the investor letter was Keysight Technologies, Inc. (NYSE:KEYS), which has emerged as a noteworthy contributor to the fund’s performance. Keysight specializes in electronic design and test solutions across various industries, including communications, electronics, and aerospace and defense. As of March 27, 2026, Keysight’s stock closed at $279.06 per share, reflecting a one-month decline of 10.92%, yet boasting a substantial 52-week gain of 86.33%. The company currently holds a market capitalization of $47.86 billion.
Janus Henderson’s letter specifically praised Keysight for its solid performance, stating, “The largest positive contributors at the stock level included TSMC, Keysight Technologies, Inc., and Knorr-Bremse. Keysight is an electronic design and testing company at the heart of the digital revolution, providing solutions to help accelerate innovation in industries such as communications, networking, electronics, semiconductor, automotive, aerospace, and battery manufacturing. The company delivered a material acceleration in order growth and guided meaningfully above consensus, with core order growth reaching double digits and broad-based strength across its segments. Keysight offers a lower-beta, defensive way to participate in the AI infrastructure build-out, with earnings momentum just starting to turn.”
Despite its strong performance, Keysight Technologies, Inc. is not listed among the 40 most popular stocks among hedge funds heading into 2026. Data indicates that 51 hedge fund portfolios included Keysight at the end of the fourth quarter, up from 44 in the previous quarter. The company reported a 23% increase in revenue during the first quarter of fiscal 2026, reaching $1.60 billion. While analysts recognize Keysight’s potential, there is a belief that certain AI-focused stocks could offer greater upside with less risk.
The investor letter also pointed to broader market dynamics affecting technology stocks, particularly those engaged in AI and related sectors. The underlying sentiment suggests that, while Keysight displays robust fundamentals, investors may be inclined to seek alternatives that could yield better returns amid shifting economic conditions. The letter indicates a cautious but optimistic view of the future, reflecting a nuanced understanding of both the challenges and opportunities present in the current market.
Moving forward, investors may want to consider the ongoing developments in AI infrastructure and associated technologies, which are expected to drive growth across various sectors. As companies like Keysight continue to innovate and adapt, their performance will be closely monitored by investors and analysts alike. The evolving landscape of technology investment remains dynamic, with significant implications for the broader equity markets.
For those interested in further insights, Janus Henderson’s report emphasizes the importance of strategic stock selection in navigating the complexities of today’s financial environment. The fund’s focus on high-quality companies that align with long-term trends is a focal point of its investment thesis as it faces an increasingly competitive market landscape.
