ten-bagger
n.— «Lynch candidly eschews the Graham-Dodd-Buffett approach, instead aiming to nail a “ten-bagger” as often as possible, so he is willing to take a flier on the next Dunkin’ Donuts in the hope that his tenfold win will offset three simultaneous losses.» —“Seven Pillars Of Wisdom” by Joe Queenan Forbes June 26, 1989.
