Against the Box
Describing the action of short selling a security one owns. When one sells against the box, gains and losses are equalized by the long position on a security combined with the short position created by the short sale. One formerly sold against the box generally in order to be able to claim profits on the sale in the following tax year, but the Taxpayer Relief Act of 1997 largely removed this loophole.
