Blow-off top(redirected from Blowoff Tops)
A sudden, rapid increase in a security's price followed by an equally sudden, rapid decrease. A blow-off top can result in large short-term gains, provided one sells the security at exactly the right moment. Just as likely, however, is the possibility that one will incur a loss by buying at the top price. A blow-off top can result from either sudden news or a rumor. See also: Reversion to the mean.
