Gap Trading Strategies: Morning Momentum
Gaps >2% offer explosive moves but most fail. Learn gap-and-go, gap-fill, and partial-fill patterns. Includes entry rules, stop placement, and profit targets.
The Gap Trading Reality
70% of gaps fill within 3 days. But the 30% that don't can run 10-20%. The key is knowing which gaps to fade and which to follow.
The 3 Types of Gaps
| Gap Type | Size | Catalyst | Strategy |
|---|---|---|---|
| Gap-and-Go | >3% | Strong news | Follow momentum |
| Gap-Fill | 1-2% | No news | Fade the gap |
| Partial-Fill | 2-3% | Mixed news | Wait for direction |
Strategy 1: Gap-and-Go
When Gaps Continue Higher
Gap-and-Go Criteria:
- • Gap >3% on strong fundamental news (earnings beat, FDA approval, major contract)
- • Pre-market volume >50% of average daily volume
- • Stock holds gap in first 30 minutes (doesn't fade below open)
- • Sector is strong (not fighting the trend)
Entry Rules:
- • Wait for first pullback after 9:30 AM open
- • Enter when stock bounces off 9:30 AM open price (support)
- • Stop below 9:30 AM low
- • Target: Previous day high + gap size
Real Example: NVDA Earnings Gap (Nov 2025)
- • Previous close: $180.00
- • Gap open: $191.00 (+6.1% on earnings beat)
- • 9:45 AM pullback to $190.00
- • Entry: $190.50 (bounce off support)
- • Stop: $188.50 (below 9:30 low)
- • Target: $198.00 (prev high $187 + $11 gap)
- • Result: Hit $197.50 by 2 PM (+3.7% gain)
Strategy 2: Gap-Fill
When Gaps Fade
Gap-Fill Criteria:
- • Gap 1-2% with NO fundamental news
- • Pre-market volume is weak (<20% of daily average)
- • Stock fails to hold gap in first 15 minutes
- • Market/sector is weak
Entry Rules:
- • Wait for stock to break below 9:30 AM open
- • Enter short when it breaks previous day close
- • Stop above 9:30 AM high
- • Target: Previous day low or gap fill (previous close)
Real Example: AAPL Fake Gap (Jan 2026)
- • Previous close: $185.00
- • Gap open: $187.50 (+1.4% on no news)
- • 9:45 AM: Breaks below $187.00
- • Entry: $185.00 (breaks previous close)
- • Stop: $188.00 (above 9:30 high)
- • Target: $183.00 (previous day low)
- • Result: Hit $183.50 by 11 AM (+0.8% gain on short)
Strategy 3: Partial-Fill
The Tricky Middle Ground
Gaps of 2-3% often fill 50% then reverse. This is the hardest to trade.
Partial-Fill Strategy:
- • Wait for gap to fill 50% (halfway between open and previous close)
- • If it bounces at 50% level, buy the bounce
- • If it breaks through 50%, wait for full gap fill then look for reversal
- • Stop is tight (1-1.5%)
Gap Trading Rules
✓ DO: Trade Liquid Stocks Only
Gaps in low-volume stocks are traps. Stick to stocks with >5M daily volume.
✓ DO: Wait for Confirmation
Never trade the gap at 9:30 AM. Wait 15-30 minutes to see if it holds or fades.
✗ DON'T: Chase Gaps
If you missed the gap, wait for a pullback. Chasing gaps at the high is how you lose money.
✗ DON'T: Hold Overnight
Gap trades are day trades. Close by 3:30 PM. Don't hold overnight hoping for more.
The Bottom Line
Gap trading is about reading the market's reaction in the first 30 minutes. Strong gaps with news and volume continue. Weak gaps with no catalyst fade. Wait for confirmation, use tight stops, and take profits quickly.
The gap tells you what happened overnight. The first 30 minutes tells you what happens today.
