10 Takeaways from the Past Three Years

Time flies. It has now been over three years since GMO launched our Small Cap Quality Strategy in September 2022. During that period, the world has shifted, and we have navigated unexpected market conditions. We are truly proud to have delivered strong performance relative to the S&P 600, in excess of 4% per annum, net of fees. Our “live” window closely aligns with the modern age of AI, birthed by the release of ChatGPT. This is an era full of promise, but also of disruption. Furthermore, small cap investors have had to tiptoe through minefields such as the banking crisis in 2023 and the “Liberation Day” tariffs in 2025.

Everything looks straightforward in hindsight and a backtest. Lived experience managing a portfolio can prove quite different. Our anniversary and the turn of the calendar year offer a natural point to reflect on the strategy's performance, key drivers of returns, and what we’ve observed along the way. Let us now revisit some of our critical stock picking rules and our observations on how our approach has fared in practice.

Top 10 Insights

1. Quality Persists in Small Caps
Companies with high and stable profitability, strong balance sheets, and disciplined capital allocation demonstrate a durable advantage that holds across regions and size bands. U.S. Small Caps are no exception, as demonstrated through our systematically defined Small Cap Quality Universe, which serves as the foundation for our stock selection. This universe has a long-term track record of outperforming the S&P 600 and the broader small cap opportunity set. This trend continued over the last 3 years. Small cap quality stocks delivered exceptional outperformance over the period.

While we cannot say with certainty why the quality advantage is so persistent, some behavioral aspects of markets can perhaps help explain it. The market struggles to price the long duration of high returns and outperformance that the best companies can deliver. Valuations implicitly forecast a decay in profitability for even the highest-quality companies, which are, in fact, best positioned to resist reversion to the mean. The compounding that the best companies deliver generates value in the very long term, outside the time horizon of many investors. Career constraints often lead investors to prioritize opportunities with near-term high returns/high risk outcomes, and such distributions are more common in junk stocks than in quality investments.

2. Tracking Error is the Price of Admission
One might expect a behavioral anomaly, such as the outperformance of quality stocks, to be competed away over time by academically oriented investors who discover an attractive opportunity. We are often asked by clients why we believe the quality effect persists, even though it is by now widely known. Variation in returns is a significant part of the story: if you own quality companies, your portfolio will look very different from small-cap benchmarks, which can be challenging for many. The higher tracking error presents a deterrent, preserving the opportunity for those willing to experience a different return profile. Indeed, though small cap quality investing has a very good track record, we have been surprised to find relatively few managers pursuing strategies similar to ours.
