RE:Ouchhhhhgheet...I got burnt by not waiting a little longer, too, but my view is that you can buy on the way down, or wait and buy it on the way back up. But you aren't going to time either the top or the bottom perfectly, so why not just buy when the price is right? SLW is clearly getting oversold here.
That said, I'm still holding plenty of dry powder for the Mother of all Smack-downs (MOAS) - and, so far anyway, this ain't it.
