In business, the term boiler room refers to an outbound call center selling questionable investments by telephone. It usually refers to a room where salespeople work using unfair, dishonest sales tactics, sometimes selling penny stocks or private placements or committing outright stock fraud. A common boiler room tactic is the use of falsified and bolstered information in combination with verified company-released information. The term is pejorative: it is often used to imply high-pressure sales tactics and, sometimes, poor working conditions. Business structure The classic image of a boiler room is that it has an undisclosed relationship with the companies it promotes, or an undisclosed profit motive for promoting those companies. Once the insider investors are in place, a boiler room promotes (by telephone calls to brokerage clients or spam email) these thinly traded stocks (i.e. stocks that are not purchased or sold very often) where there is no actual market. The brokers of the boiler room actually "create" a market by attracting buyers, whose demand for the stock drives up the price; this gives the owners of the company enough volume to sell their shares at a profit, a form of pump and dump operation where the original investors profit at the expense of the investors taken in by the boiler room operation. In the 20th century, the U.S. Securities and Exchange Commission described boiler rooms as follows: Some traits of a boiler room include presenting only good news about the stock to be sold, and discouraging outside research by customers or brokers working there.

In the early 1970s (and possibly earlier), boiler room was a term used by political parties for a room with many telephones used to call prospective voters. Modern boiler rooms In the late 1960s to the 1980s, boiler rooms sold municipal bonds to unsophisticated investors. These boiler rooms were located primarily in the southeastern United States, most notably Memphis, Tennessee and later Little Rock, Arkansas. The operators got the nickname "Bond Daddies."
