Rogue Trader

A rogue trader is a trader who acts recklessly and independently of others, usually to the detriment of the institution that employs the trader and perhaps clients. Rogue traders typically play with high-risk investments that can produce huge losses or gains. Rogue traders, though, are only labeled as such if they lose. If their trades are enormously profitable, no one calls them rogue. They are more likely to receive a huge bonus.
