The "Pump And Dump" Scam
It's common to see messages posted online that urge readers to buy a stock quickly or tell you to sell before the price goes down. Often the writers will claim to have "inside" information about an impending development or to use an "infallible" combination of economic and stock market data to pick stocks. In reality, they may be insiders or paid promoters who stand to gain by selling their shares after the stock price is pumped up by gullible investors. Once these fraudsters sell their shares and stop hyping the stock, the price typically falls and investors lose their money. Fraudsters frequently use this ploy with small, thinly-traded companies because it's easier to manipulate a stock when there's little or no information available about the company.

While some messages may be true, many turn out to be bogus – or even scams. Fraudsters often pump up a company or pretend to reveal "inside" information about upcoming announcements, new products, or lucrative contracts.
Also, you never know for certain who you're dealing with – or whether they're credible – because many bulletin boards allow users to hide their identity behind multiple aliases. People claiming to be unbiased observers who've carefully researched the company may actually be company insiders, large shareholders, or paid promoters. A single person can easily create the illusion of widespread interest in a small, thinly-traded stock by posting a series of messages under various aliases.

That's what happened to BER lately.
