Look at their financials. If you have made money on the stock, my suggestion is to get out and invest in a company that actually makes a profit and doesn't have to sell more stock to increase their cash position.
how can a stock that's losing money each quarter undervalued? They had less sales than last quarter yet they lost more money? The only reason why they have cash is because they sold a bunch of stock and they aren't going to constantly do that, or is that how they are going to make their books look good? Don't get suckered into this turkey, the bottom will fall out when you least expect it when people actually wake up from their drunken stupor.
