Double Bottom

What is a 'Double Bottom'

A double bottom is a charting pattern used in technical analysis. It describes the drop of a stock (or index), a rebound, another drop to the same (or similar) level as the original drop, and finally another rebound.

BREAKING DOWN 'Double Bottom'

The double bottom looks like the letter "W". The twice touched low is considered a support level.

Most technical analysts believe that the advance off of the first bottom should be 10-20%. The second bottom should form within 3-4% of the previous low, and volume on the ensuing advance should increase.
