Hayden Capital, an investment management firm, released its fourth-quarter 2025 investment letter. A copy of the letter can be downloaded here. 2025 proved how unpredictable markets can be in the short term. Markets displayed broad strength, highlighting their resilience. U.S. equities saw double-digit gains, while international markets performed even better. Remarkably, international stocks outpaced their U.S. counterparts for the first time since 2017. The firm had a productive 2025, especially as investor capital focused on anything related to AI, while other sectors were labeled as “AI losers.” In Q4 2025, the portfolio returned -12.9% compared to the S&P 500's +2.7% and MSCI World's +3.3%. The portfolio had returned +14.8% annualized after fees, since inception, compared to the S&P 500’s +13.5% and MSCI World’s +10.3% return. Approximately 42% of the portfolio is invested in Asia, ~41% in North America, ~16% in Latin America, and the rest in cash. Due to the influence of AI, the market is responding more to fear and rising uncertainty about the future rather than to facts.
