SI340: ETFs, Size, and the Commodity Problem ft. Alan Dunne

In today’s episode, Alan Dunne and I take a step back - and a step forward - by exploring 125 years of hard-earned market wisdom, courtesy of the Global Investment Returns Yearbook, the definitive source of long-term asset class performance. What does this rich dataset tell us about equities, bonds, diversification, and the underrated role of patience in investing? And how relevant are these lessons for investors navigating today’s high-concentration markets, stubborn inflation, and the potential cracks in the classic 60/40 portfolio?

But that’s not all - we also dive into one of the most overlooked challenges facing systematic trend followers today: capacity constraints, especially in commodities. Drawing on Quantica’s latest research, we examine why commodities have historically been critical to CTA performance, how liquidity limits silently erode returns as strategies scale, and why the explosive growth of trend following ETFs may come at a hidden cost investors rarely see.
