What they do is called short and distort the stock scams. They do this by having someone write bearish or negative articles about the target companies or stocks. These articles normally picked up by bloggers and media portals that then start blasting different versions of the articles all over the net. They also proceed to crash message boards with more negative posts. One will support the other to try to give credibility to the whole process. They may send emails to analysts to get them to write more negative articles or reports. Some may even send false and misleading information to reporters, especially if the stocks are in a bear market.
You have to do your due diligence on these reports and the persons writing them. For example, Andrew Bary of Barron's is a history major/reporter. I don't think he is actually an analyst. He think that VZ should be worth $100 a share and FB no more than $25 a share. These are just opinions on valuations and price targets. People did not blast the VZ story all over the net but shorts blasted the FB story because they stood to gain from a decrease in its stock price (short or put option positions).
Not to mix apples with oranges here. VZ is very labor intensive while FB is not. The evaluations of both would therefore be different. FB could monetize its sites with very little capital outlay. It is also in the beginning of its marketing/business cycles. It has not reached maturity in its effort to monetize over 1.1 billion users. Marketers are looking at ways to tap into these households without being too intrusive. FB only needs to get about $100 per person of 300 million users. I see this as being possible long-term. The market is looking for the company to leverage its free service. There are already companies doing this and they trade very high. One company I know grows revenues at almost 100 percent YoY.
sometime there are more than 5-6 upgrade type messages but stock does not even move, at the same time some F. idiot says something negative and stock goes down. There is a big game playing by money hungry #$%$ holes, definitly there is big game on FB stock.They beat the estimate nothing happened, Netflix made $ 3mil, stock went up 25%.
