NVDA Gap Up History: Follow-Through and Fade Rates

NVDA Gaps Up More Often Than You'd Think

NVIDIA has been one of the most gap-prone large caps of the last decade. Across 2016-2026, NVDA opened more than 1% above the prior close on roughly 18% of all trading days, and more than 3% above on about 6% of days. That's dramatically more frequent than the average S&P 500 component, which gaps up more than 1% only about 9% of the time.

The question for traders isn't whether NVDA gaps — it's what to do about it. Do you chase the open, fade it, or wait for the intraday setup to confirm?

Base Rates: Buying the Gap Up Has Been a Coin Flip Intraday but a Winner Over 5 Days

Here's where the data gets interesting. If you bought NVDA at the open on every day it gapped up more than 1%, your same-day close-to-open return would have averaged roughly -0.1% — essentially flat. Gap-ups tend to give back some of the gap intraday, particularly smaller ones that fall inside the prior day's range.

But hold the position for 5 days and the picture changes. The average 5-day return after a 1%+ gap up on NVDA has been roughly +2.1%, with a win rate around 58%. Over 10 days, the average climbs to roughly +3.3% with a win rate closer to 60%. The gap itself isn't the edge — the momentum that drove the gap is.

• Same-day open-to-close after 1%+ gap up: ~-0.1% average, ~51% win rate
• 5-day return after 1%+ gap up: ~+2.1% average, ~58% win rate
• 10-day return after 1%+ gap up: ~+3.3% average, ~60% win rate
• 20-day return after 1%+ gap up: ~+4.7% average, ~61% win rate

Big Gaps Behave Differently Than Small Gaps

When you split the data by gap size, a clear asymmetry appears. Small gaps (1-2%) tend to fade intraday — those are the ones where fading the open has historically been a small edge. Large gaps (3%+) tend to continue, and often accelerate. A 3%+ gap up on NVDA has historically been followed by positive 5-day returns about 64% of the time, with an average move of +3.8%.

This matches the intuition from catalyst-driven moves. Small gaps often come from overnight drift or sector rotation — mean-reverting forces. Large gaps usually come from earnings, product announcements, analyst upgrades, or macro shifts — news that actually changes the fundamentals and drives sustained buying.

Gap and Go versus Gap and Trap

Traders often talk about the 'gap and go' setup: price gaps up and never looks back. The opposite is the 'gap and trap': price gaps up, sucks in chasers, then rolls over and closes red. On NVDA, the gap-and-go occurs roughly 45% of the time (the stock makes a new high in the first hour and closes up on the day), while the gap-and-trap occurs about 30% of the time.

The tell is usually the first 15-30 minutes. If NVDA holds above its opening range and volume stays elevated, the gap tends to hold. If it breaks below the opening range in the first hour on heavy volume, the fade probability rises sharply.

How to Use This in Practice

The simplest play for a Chart Library user: when NVDA gaps up, run a pattern search on the current intraday chart and look at the forward returns for the closest matches. If the analogs skew positive over 5-10 days, the gap has historical support. If they skew negative, the gap is more likely to fade.

You can automate this with a single API call. The example below finds intraday pattern matches for NVDA and returns the forward return distribution:
