While the recent price action is definitely to my advantage, I'm long. I think the stock is probably fairly valued. RPM is currently trading 18x 2015 estimates and at a premium to its historical dividend yield.
I bought a bunch during the 2009 period when it looked like the world may stop turning. Sold about 20% a month or so ago. Just being prudent as I had a 200+% profit. The rest of the shares, I'm holding as I'm also in agreement that RPM is generally well run. And who doesn't like a dividend increase every year?
