In our Q4 2025 Commentary we address the main drivers behind market performance and macroeconomic developments, focusing on five key questions that reflect the evolving investment landscape.

1. What were the key macroeconomic challenges in Q4 2025, and how did they affect market analysis?

The fourth quarter was marked by significant uncertainty, largely due to a 43-day government shutdown that restricted access to critical economic data. This made it difficult for investors and analysts to assess the true trajectory of the economy. Even when data was released, it was often incomplete—for example, the inflation report was missing the shelter component, a key factor in understanding the full inflation picture. Despite these challenges, corporate earnings data (which was not affected by the shutdown) painted a positive picture, with strength broadening across small, mid, and large cap stocks.

2. What does the recent performance of small cap equities reveal about the current market cycle and the durability of recent market gains?

Small caps emerged as a standout in 2025, especially in the second half of the year. While the past three years saw strong equity returns concentrated in mega-cap stocks, Q4 marked a shift as small caps outperformed, particularly those with no earnings and high leverage. This rally was driven by speculative segments, such as biotech and quantum computing, where many companies remain unprofitable. The health care sector, especially speculative biotech, saw dramatic outperformance, reflecting a pronounced appetite for risk among retail investors. However, history suggests that unprofitable or highly levered companies tend to underperform over the long term.

3. How should quality investors approach sector selection and portfolio construction in an environment dominated by speculative rallies and shifting market leadership?

4. What are the risks and opportunities associated with investing during major technology transitions, such as the AI boom?

The current environment is characterized by a speculative, low-quality rally, making it challenging for professional managers to outperform benchmarks. The Magnificent 7 remain well positioned to benefit from the AI boom, but much of the capital investment is concentrated in a few dominant players, introducing risk if spending slows. The commentary draws parallels to past technology transitions, noting that while some changes are absorbed smoothly, others can be highly disruptive. The key for investors is to focus on companies with strong earnings prospects and competitive advantages, while remaining mindful of potential disruption.

5. What are the additional risks investors should consider as we approach 2026?

Risks for 2026 are closely tied to the evolving political climate, with the U.S. midterm elections potentially leading to shifts in the House and Senate and increased market volatility. Affordability remains a central theme, and changes in government composition could impact regulation and policy direction. Geopolitical tensions in Latin America and the delayed impact of tariffs on input costs are also highlighted as risks. Additionally, recent bankruptcies in the private credit market and a softening labor market—exacerbated by reduced immigration—pose structural challenges for economic growth.
