"Pump & Dump" Spam

This is a common scam where spam emails hype shares of little known companies, of which the spammer has previously aquired stock. When sufficient people fall for the scam and start placing buy orders, the market value of the stock rises and the spammer can sell at a profit. Once the spam stops providing new buyers the stocks start to deflate again and the new onwers take a loss as the price drops back to previous levels or below.

Here is some more information about this type of fraud:
