Site Plug for those unaware of the insider trading tracker Form 4 Oracle Insider Trading. For me one of the best signs that a company is ready to make a big move is to watch the insider trades. Especially if the CFO is buying. This is because the CFO is the money guy. He isn't the CEO/Plug for the company who may buy just to pump the stock. The CFO is all about the bottom line, and usually only invests if things are looking good.
