In the investor letter, SouthernSun Asset Management reflected on the economic lessons learned during the oil price collapse of 2014-15. Initially viewed as a positive development for the global economy, the decline in oil prices exposed underlying weaknesses that had broader economic impacts beyond the energy sector. Drawing parallels to the current scenario with artificial intelligence (AI), the firm cautioned that while AI is now integral to economic planning and decision-making, its associated risks must be carefully analyzed.
As the market heads into 2026, SouthernSun Asset Management remains focused on intrinsic value and maintains a disciplined approach. The firm is optimistic about the future but remains mindful of historical lessons. The investment landscape is shaped by various scenarios, including valuation compression and overcapacity in AI infrastructure, rather than pre-determined outcomes.
