What is Boiler Room?

Traditionally the term boiler room is used to describe a fraudulent brokerage that is set up in order to offload certain unwanted securities belonging to the owners of the firm, typically penny stocks. In recent years the term has become synonymous with any company that employs telephone sales teams who use aggressive high-pressure sales tactics, and wildly misrepresent the products that they are attempting to sell.
