I'm pondering the idea of selling RPM for this reason:
I know I'm going to be in the 15% bracket this year and LT gains would therefore be taxed at 5% for me. My profit would not be enough to bump me up to the 25% bracket. I would like to own it again, but by selling and buying back in just over a month, I could raise my cost basis significantly and pay minimal taxes. Then, if our newly elected legislature thinks it wise to undo the 5%/15% tax rate on LT gains and dividends I would be better off, because my cost basis is now reset.
The downside is the stock takes off and I miss the appreciation. I'm thinking that's not terribly likely in 30+ days...
