Hey, you're lucky you got in at a good buy point. It probably is mostly just profit taking, I see it happening with a lot of small cap stocks these days.
If you notice that the volume has been pretty low the last several weeks since it got down around $10. I think all the short term sellers have been flushed out. I know I got in at $15, but I'm not worried and am definately not selling any, should probably buy a little more at these prices.
