Are there any reliable sources of stock information on the net?
The best place to get legitimate information on weather a stock is being bashed or pumped is BasherBuasters.com. You should treat anything you read on the Internet with suspicion, particularly in cases where that information is provided by people who might have a financial interest in a particular stock. Be particularly suspicious of 'tips' posted by people in newsgroups and bulletin boards.
Portals such as Yahoo and Google often offer stock information, including official documents filed by the company, and graphs of the stock's performance to date. Large organizations (portals, news services etc) with a solid reputation and no particular reason to promote one stock rather than another are a safer guide than 'some guy you met in a chat room'.
