The engulfing pattern is a two-day reversal signal. On the second day the candle’s body completely swallows the body of the day before, in the opposite colour. A big up day that wipes out a down day is a bullish engulfing; a big down day that wipes out an up day is a bearish engulfing.
It’s one of the most widely quoted patterns, and it’s common enough to test properly. Our scanner has logged 15,667 bullish and 17,933 bearish engulfing patterns across 559 US stocks and ETFs since late 2023.
How it’s defined
- Day one has a real body in one direction.
- Day two opens beyond day one’s close and closes beyond its open, so its body covers day one’s body completely.
- Bullish: day one is down, day two is up. Bearish: the reverse.
Shadows don’t count, only bodies. And textbook versions say it should follow a trend in the opposite direction, which I test below.
The headline numbers
| After a… | Cases | Higher next day | Higher 5 days later | Higher 20 days later |
|---|---|---|---|---|
| Bullish engulfing | 15,667 | 50.0% | 53.5% | 56.0% |
| Bearish engulfing | 17,933 | 53.5% | 54.1% | 55.2% |
| Any day | 413,576 | 51.9% | 53.8% | 55.6% |
Two things jump out. A bullish engulfing day was followed by an up day less often than a random day, 50.0% against 51.9%. And a bearish engulfing day was followed by an up day more often, 53.5%. Big one-day moves tend to partly reverse the next day, whichever direction they went. Over a week, both versions end up right around the baseline.
The trend matters, but not the way you’d hope
Here’s the bullish version split by the 10 days before it:
| Before a bullish engulfing | Cases | Higher 5 days later | Higher 20 days later |
|---|---|---|---|
| Fell more than 5% | 2,807 | 49.0% | 59.5% |
| Flat | 9,652 | 53.4% | 55.0% |
| Rose more than 5% | 2,697 | 55.2% | 54.8% |
| Any day after a 5% fall | 54.0% | 56.3% |
The textbook setup, a bullish engulfing after a selloff, did worse than a random day over the next week: 49.0% against 54.0%. But over the next month it did better, 59.5% against 56.3%. My reading is that the engulfing day itself is often a sharp bounce that gives some back right away, and the recovery comes later. If you trade it, give it time, or wait for the first pullback.
The bearish version barely changed with the trend. After a 5% rally, a bearish engulfing was followed by a gain 54.1% of the time, almost exactly the baseline. It didn’t call tops.
Confirmation makes a small difference
| Cases | Higher 5 days after the next day | |
|---|---|---|
| Bullish engulfing, then a higher close | 7,579 | 54.6% |
| Any up day | 206,605 | 52.7% |
| Bearish engulfing, then a lower close | 8,035 | 52.6% |
| Any down day | 192,451 | 54.0% |
Both versions do slightly better than their baseline once the next day follows through: about 2 points for the bullish one and 1.4 points for the bearish one, with a margin of error around 1 point. Small, but in the right direction for once.
How I’d use it
- Bullish engulfing after a selloff: don’t chase the day itself. If you like the stock, wait for the next few days to settle and look at a bull put spread or cash-secured put below the engulfing day’s low.
- Bearish engulfing: I wouldn’t short on it alone. It’s more useful as a nudge to tighten a stop or sell a covered call on a position that has run up.
