This is one of my favorite interviews of 2025. I just sat down with Jeff deGraaf, founder of Renaissance Macro Research, to get his thoughts on markets, cycles, and risk.
Jeff built his career translating technical analysis into actionable investment strategies for institutional clients. Institutional Investor has named him the #1 technical analyst for over a decade.
In this conversation, he walks through Jeff’s market cycle clock—a framework that plots inflation against growth to forecast stock market returns—and explains why inflation matters more to stocks than GDP growth does.
We cover:
• Why trend following beats mean reversion for long-term investors
• How to identify bubbles—and what to do when you’re in one
• Where semiconductors and healthcare sit on the valuation spectrum
