Big Swinging Dick
(Very) informal and somewhat derogatory; a trader who believes his methodology is perfect and will always result in sizable profits. However, it originally was a term of self-designation for major bond-traders. The term was popularized by the book Liar's Poker, which describes the author's experience as a bond trader on Wall Street in the 1980s.
