What is a Follow-Through Day?
A Follow-Through Day (FTD) is a market-timing concept developed by William O'Neil (creator of CANSLIM) to help identify the start of a new uptrend after a correction.
How it works
- 1. Market enters a correction (5%+ drawdown or breaks below 50-day MA).
- 2. A rally attempt begins when the index closes higher than the previous day.
- 3. On Day 4+ of the rally, if the index gains ≥1.25% on volume higher than the prior day, that's an FTD. Days 4–7 are the prime window; signals can also occur on later days.
- 4. The FTD fails if the index later undercuts the correction low.
Important caveats
- • Not every FTD leads to a sustained rally — some fail when the index undercuts the correction low.
- • Every major market bottom was preceded by an FTD — it's a necessary but not sufficient condition.
- • Our 5-year backtest: SPY 87.5% success (7/8), QQQ 67% (12/18). QQQ triggers more often due to higher volatility.
- • Use alongside breadth, leadership quality, and your own analysis.
- • This tool is educational — not investment advice.
