Kaka hăy đọc cái đoạn nầy : PUMP AND DUMP :
+Pump & dump scams are also a classic manipulation play. While there are different arrangements from scam to scam, the basic idea is to tout the supposed prospects of a company in an attempt to lure in unsuspecting investors that will push up the price. As the price goes up, the original scammers sell their stock to the new blood and book a nice profit.
+Sometimes the company itself engages in the promotion, and other times the insiders hire promoters to pump the stock. +In any case, you begin to see streams of press releases and/or "research reports" from companies that you never heard before . There's a remarkable similarity between them, for example, new technologies that will revolutionize an industry, imminent cures for dread diseases, and so on. Of course, none of the garbage is true, and once the insiders have sold out, the hype machine shuts off. Once the hype dries up ,the stock crashes, volume dries up, and investors go away licking their wounds .
+Pump & dump scams are overwhelmingly more common in the penny-stock world, so the first step in avoiding this type of manipulation is to avoid penny stocks in general. There are also plenty of frauds and scams among listed stocks (Enron, anyone?), but there are considerably more critical eyes looking at listed stocks, and the hype isn't usually as blatant.
+The nature of the hype is also a good warning. Since these companies are overwhelmingly just junk (usually without products or real sales), the promotional material always talks about the fantastic future -- great new products about to be released, lucrative contracts with major companies just about to be announced, and so on. Ask any of these companies about what's going on today, and you'll get blank stares and quick attempts to turn the conversation to the glorious future.
