Over the course of a month? The reasons you give for thinking these stocks might go up aren't things that would reliably manifest in such a short time frame, and the market generally has been down recently. I don't think what you've described here is evidence of much of anything. Probably you're no good at active investing, because the evidence seems to suggest that nobody is (the winners are just the ones who get lucky), but the reason to think that is because of the general evidence for that, not because of your personal experience over the past month.
