Double Bottom Pattern: The Most Reliable Reversal Setup in Stocks
The double bottom is what it looks like when sellers give up. They push a stock down, buyers fight back, the stock falls again — and buyers fight back again from the same level. When that second defense holds, the pattern is complete and the upside tends to be significant.
The double bottom is one of the most reliable reversal patterns because it requires sellers to test a low twice and fail both times — a structural confirmation that supply has been exhausted at that price level. The pattern is confirmed only on a close above the neckline (the high between the two bottoms), not on the second bottom itself. Volume should be higher on the second bottom than the first and surge on the neckline breakout for the signal to be credible.
What Is a Double Bottom Pattern?
A double bottom is a bullish reversal pattern shaped like the letter W. The stock falls to a support level (first bottom), bounces, pulls back to retest the same support (second bottom), then rallies above the middle peak — called the neckline. Two failed attempts to break support signal that sellers are exhausted and buyers have found a floor.
How to Trade It
Entry: buy on the neckline breakout, or on a successful retest of the neckline as support after the breakout. Stop loss: below the second bottom. Target: measure the height from bottom to neckline, then project that distance above the neckline. A bottom-to-neckline distance of $10 gives a $10 price target above the breakout.
The volume pattern matters. The first bottom often comes on heavy selling volume. The second bottom should form on lighter volume — sellers aren't pushing as hard. The breakout should be high volume. If the breakout candle is weak and volume is thin, treat it with skepticism.
The False Signal Risk
Double bottoms fail when the neckline breakout happens on low volume, or when the two bottoms aren't at the same level. A second bottom that's meaningfully lower than the first isn't a double bottom — it's just lower lows. The pattern requires the second test to hold at or near the same price as the first.
