I probably don't need to tell you what a fool's errand it is to make sense of the daily machinations of the stock market. That said, I do believe that $33 is a good entry point, which is why I reestablished my position when it touched that level a couple of weeks back. As to why it might be going up, well, the stock was recently added to the S&P 1000 at the end of January. This brought attention to a well performing stock in what is still a great sector, IMHO. When investors look at the financials of the company, they generally like what they see. I sure liked what I saw last year and only sold it a month or so back because I sold everything in an investing tantrum over the lack of sense of the market (My own foolishness). DORM was a baby in the bath-water. When I saw it hit on earnings, I snagged them back. I did the same thing with SPLS last week, when it dropped to the low $12's. Those two are the only individual stocks that I presently own. Good luck.
The Fed has created the biggest bubble of our lifetime, and shows no sign of letting up. We've learned nothing since 2000, and 2007. Force consumers to spend and get deeper in debt all over again. Margin borrowing is almost at record highs again. This will probably end badly, and will take DORM with it.
