How a classic "pump and dump" stock scheme works:
• A promoter buys shares of an obscure company, often one that has no operations, for as little as a fraction of a penny a share.
• The promoter touts ("pumps") the stock with spam e-mails, in Internet chat rooms or using legitimate-looking newsletters, often with outlandish claims about the stock's performance. Fraudulent sales are arranged to create the appearance of demand for the stock.
• Investors buy in, and the share price rises. At prices so low, even a small increase creates a large percentage profit for the promoter.
• The promoter sells ("dumps") shares at the artificially inflated price. The promotions end, and the stock price collapses. Investors who bought at the inflated price lose their money.
Just as Lawrence Kazmerski, a top official at the National Renewable Energy Laboratory, was about to give the keynote address at the University of Minnesota's annual E3 conference at the RiverCentre in St. Paul, the lights went out, bathing the audience in darkness and a deep sense of irony.
