What Does a Follow-Through Day Mean in IBD Investing?
In the world of IBD-style investing, few signals are as important as the Follow-Through Day (FTD). It’s a critical event that helps investors confirm whether a new market uptrend has begun after a correction.
This post explains what a Follow-Through Day is, how to identify it, and why it’s essential for making smart buying decisions in IBD investing.
What Is a Follow-Through Day (FTD)?
A Follow-Through Day is a strong up day in a major market index (like the Nasdaq or S&P 500) that occurs after a market correction or downturn.
To qualify as a Follow-Through Day:
- The index must rise at least 1.2% to 2.0% or more.
- Volume must be higher than the previous day.
- It must occur on Day 4 or later after a market low.
When these conditions are met, IBD considers the market to be in a confirmed uptrend, meaning it’s safer to begin new stock purchases.

Why the Follow-Through Day Matters
The Follow-Through Day offers a clear signal that institutional buyers are returning to the market. It tells you:
- The correction may be over.
- Big money is stepping back in.
- Buying opportunities are beginning to open up.
Many of the best stock rallies in history were preceded by a clear FTD signal.
How to Spot a Follow-Through Day
Here’s a quick checklist:
- Monitor major indexes like the Nasdaq and S&P 500.
- Count 4 days or more after the market bottom.
- Look for a gain of at least 1.2–2.0% or more.
- Confirm that volume is higher than the day before.
This combination of price and volume action is what makes the FTD such a reliable indicator in IBD’s system.

Follow-Through Day Mistakes to Avoid
- Jumping in before confirmation: Wait for an official FTD signal before buying aggressively.
