How to Screen Stocks for Seasonal Patterns

Every year, certain stocks, indices, and futures tend to move in the same direction at the same time. These are seasonal patterns — recurring price tendencies backed by decades of data.

Most traders either don't know these patterns exist. This guide walks through how to systematically screen for seasonal patterns across 4,000+ securities — the same approach built into the Seasonal Edge screener.

The Metric That Actually Matters

Every pattern in Seasonal Edge has an equity curve — a chart that shows what would have happened if you traded the pattern every single year. Each year's result stacks on top of the last, so you can see at a glance whether a pattern has been compounding gains or giving them back.

The problem is that seasonal patterns are cyclical and go through hot and cold streaks. We run cycle detection on the equity curve to classify each pattern as HOT (recent wins, uptrending equity curve), COLD (recent losses, downtrending), or NEUTRAL. A pattern with an 80% historical win rate might be in a cold regime right now — and you'd never know from the win rate alone.

The seasonal pattern is the setup. The equity curve regime tells you when to use it and when to avoid it. This is the difference between Seasonal Edge and conventional seasonality tools — we don't just find patterns, we tell you which ones are working right now.

Beyond that, the screener also shows:

Real Example: DHL.DE — 10 Trades, 10 Winners

The screener flags DHL.DE (Deutsche Post AG) with a long pattern entering around April 8, exiting around May 4. Here's the full history:

Why Spreadsheets Can't Do This

4,000 securities, each with dozens of potential patterns, across 25+ years of daily data. That's millions of data points to process, filter, and rank. A charting platform can show you one symbol at a time — but it can't screen, filter by momentum, or rank by composite score across all of them.

This screen runs daily. Every morning the data refreshes, new patterns enter the lookahead window, regimes update, and the ranked list reflects the current state of the market.

Beyond Seasonal Patterns

Seasonal screening is the starting point. The strongest setups combine seasonal tendencies with cycle-based timing — planetary harmonics, COR pivots, and cyclical overlays that confirm when conditions are most favorable. The difference between “this stock tends to rise in April” and “April 2026 specifically has favorable cycle alignment.”
