Fenimore Asset Management has recently released its Q4 2025 investor letter, detailing a year characterized by a solid yet volatile stock market. The firm noted that investors faced a challenging landscape in 2025, grappling with the excitement surrounding artificial intelligence (AI), ongoing economic uncertainty, and shifting monetary policies.
The summer saw a rally primarily fueled by robust AI-related spending and notable economic resilience. However, the fourth quarter turned turbulent, influenced by mounting valuation pressures and macroeconomic uncertainties. Large-cap technology and communication services sectors were the standout performers, as reflected by the S&P 500 Index’s increase of 2.66% during this period.
Despite these overall market trends, Fenimore’s investment strategies faced hurdles. The Fenimore Small Cap Strategy reported a return of -4.12%, falling short of the Russell 2000 Index’s 2.19% return. This underperformance was attributed to an underweight exposure to lower-quality stocks. The Fenimore Dividend Focus Strategy also experienced a decline of -4.41%, juxtaposed with the Russell Midcap Index’s growth of 0.16%. Similarly, the Fenimore Value Strategy posted a loss of -1.17%, alongside the Russell Midcap Index’s modest gain of 0.16%. Overall, investments within the financial and industrial sectors contributed to this relative underperformance.
Looking ahead, Fenimore anticipates mixed market conditions for 2026. The firm expressed concerns regarding the valuation of many AI-related stocks, which it perceives as expensive, while noting that high-quality companies are currently trading at multi-year lows. This scenario presents potential investment opportunities.
One of the focal points of the Q4 letter is Trane Technologies plc (NYSE:TT), highlighted as a significant detractor in the Fenimore Dividend Focus Strategy. Trane Technologies, which specializes in solutions for heating, ventilation, air conditioning, and transport refrigeration, is perceived to be fundamentally strong, despite facing some challenges. As of January 15, 2026, Trane’s stock had closed at $387.27 per share, reflecting a one-month return of -0.66% and a 52-week decline of 0.49%. The company boasts a substantial market capitalization of $86.174 billion.
In its analysis, Fenimore remarked on Trane Technologies’ strong earnings and backlog, noting that AI data center cooling has been a positive factor for the firm. However, they pointed out that the residential HVAC sector is facing difficulties as the industry transitions to new refrigerants, a situation common across many firms in this space. Fenimore expects to gain further clarity on this issue soon.
Despite Trane’s stable presence in the market—evidenced by its inclusion in 58 hedge fund portfolios at the close of Q3 2025, a slight increase from the previous quarter—Fenimore believes that other AI stocks may present greater upside potential with less downside risk. For those interested in AI-driven investments, the firm has highlighted particularly strong short-term AI stocks that could benefit from favorable market trends.
In summary, Fenimore Asset Management’s latest investor letter paints a nuanced picture of the investment landscape, balancing potential opportunities while addressing the challenges presented by both macroeconomic factors and sector-specific dynamics.
