Bagholder

In U.S. financial slang, a bagholder is a shareholder left holding shares of worthless stocks.

The shareholders could be caught up in a corporate bankruptcy and accounting scandal, as was the case with Enron and Worldcom, or the victims of a pump and dump scheme, in which naive and unsophisticated investors fall victim to e-mail spam, rigged stock tip forums, or other tricks used by stock touts to drive up the shares of worthless penny stocks.
