Well, it's inching back toward 4, I went ahead and got 1k shares. Will buy more if it drops further. They are a good sized company in a competitive product that relies on the shaky solar business. On the other hand their balance sheet is built like a tank. Even at projected PE of 14-15 or whatever it is, if you back out cash their PE ratio is more like 6.
Not sure there's a lot to look forward to in the near term, but the downside on this stock is heavily mitigated by their excellent balance sheet.
