I spent 30 years in the institutional trenches as a trader, analyst, and portfolio manager, eventually running the equity trading desk at Northern Trust in Chicago. Those decades shaped my approach: stay disciplined, trust the data, and keep emotion out of the way. Since 2009, when I began publishing my stock selections, my portfolio has delivered solid long term results—compounding in the mid teens annually through 2025. Today I manage a 15-20 stock model portfolio where I select stocks that score highly for Quality, Growth, Momentum, Value, and Risk. I use a rules-based framework that helps me build high performing portfolios. My work focuses on systematic thinking, behavioral awareness, and evidence over opinion.
