SouthernSun Asset Management, LLC, an investment management firm, released its “SouthernSun Small Cap Strategy” fourth-quarter 2025 investor letter. A copy of the letter can be downloaded here. During the quarter, the Small Cap Composite returned -2.45% on a gross basis (-2.64% net) compared to 2.19% for the Russell 2000 Index and 3.26% return for the Russell 2000 Value Index. The Composite returned 6.21% on a gross basis (5.40% net) over the trailing 12 months compared to 12.81% and 12.59% for the indexes, respectively. The letter highlighted the economic lessons learned during the oil price collapse of 2014-15. Initially seen as a positive development for the global economy, the decline in oil prices later revealed underlying weaknesses, leading to broader economic impacts beyond the energy sector. The author compares this to the current situation with artificial intelligence (AI), cautioning that while AI is now a fundamental aspect of economic planning and decision-making, its associated risks must be carefully analyzed. As the market approaches 2026, the investment landscape is shaped by various scenarios, including valuation compression and overcapacity in AI infrastructure, rather than inevitable outcomes. SouthernSun Asset Management maintains a disciplined, humble approach focused on intrinsic value and is optimistic about the future but remains aware of historical lessons.
