I seldom look at SEC filings. I just find a stock that is in an uptrend and trade it. Or, I find a stock in a downtrend that had a lot of volume recently and seems to be finding support. I'm considering trading the short side of the market for some stocks. I rarely do that because it can be rather risky. But, I have seem a lot of situations lately where trading the short side when you have an obvious top formation can actually make more money more quickly than trading long. But, there is no room for mistakes when you are trading short so you have to be sure you know what you are doing.
