How can I find out what factors are making a stock's price rise?
A few days ago they launched Fannie Mae Guaranteed Multifamily Structures (link) but who knows?  It's a penny stock now. Google Finance is pretty good at marking news right on the chart for a particular stock.  That's how I tracked that piece of news down.  Can't say that it precipitated a lot of people buying the stock, but Google Finance isn't a bad place to start looking.
