DEFINITION of 'Blowoff'

A term in technical analysis that refers to a sharp price increase that comes after a long period of price appreciation, and is followed by a fall in the price. A blowoff is seen as a rally's last breath and is a highly bearish sign.


This large and dramatic price movement is generally seen at the peak of a market or stock. The idea behind the bearishness of a blowoff is that it signals the activity of the most irrational and overly exuberant market participants, who, wanting to take part in the rally, momentarily push up the already-overvalued stock.
