The last couple of dips surely worked nicely for me. I've mentioned before that my investment methodology involves buying a certain amount every month. I buy whichever of my companies looks to be underpriced--usually because it is below it's 500 day moving average price. The problem with that system is that usually when Raven (or any other stock in my portfolio) is underpriced I have already spent my budget on something else even more or earlier underpriced.
On this occasion, however, nearly everything else I own is hitting new highs and only Raven was in buy range. So I bought right up to my maximum holding of any one company. Still could buy more and just may though I'd rather pay $25 or less. A PE of 20 (based on real earnings from the past 4 quarters) is getting up there pretty well as far as I'm concerned and I'm inclined to begin looking at selling some if it gets over $29 or so.
