Editor’s Note: Most investors spend a lot of time deciding what to buy. TradeSmith CEO Keith Kaplan believes we should spend just as much time thinking about when to buy it.

Keith has spent years studying recurring seasonal patterns across thousands of stocks. That research became the foundation for TradeSmith’s Seasonality tool, which helps identify historically favorable buying and selling windows. In an 18-year backtest, the strategy produced 857% total growth, more than double the S&P 500 over the same period.

Results like that are hard to ignore. That’s one reason I recently joined Keith for his upcoming Breakthrough 2026 event. In today’s guest essay, he explains how it all works and why timing can matter just as much as stock selection.
