Nevertheless, hope springs eternal. If you really want a stock that is going to double, you need to find a good story that hasn't gotten widely told. The best indicator of that is low volume, not low price. There is some kind of mystical association of press releases with breakouts of a stock price. And while it does happen, it rarely happens when you know a press release is coming.
Information travels fast and far.
It is far wiser to assume that if you know the press release is coming out, so does everyone who is interested in the stock. There have been many examples of this with the announcement of web sites. But everyone already knows what it is in the release. After all, it's in the chat room. But the day before the press release, this stock traded only 100 shares.
