"On the one hand, I feel a little chastised for being one of those silly folks who try to trade in and out. Like most folks I don't think I'm dumber than average, but surely about half the population thinking that has to be wrong, and I may well be one of them.

Valuation sure do change. Since I bought that share last Oct 27, known book per share is up 4.4% and price/book ratio is up 25.9% from 1.334 to 1.680.

It's a calculated gamble that the stock price return from now till then will be either negative or low enough that I won't miss it."

I'm just not one of them. I'm the kind that needs a daily reminder not to do something stupid:-). And it's wife that usually serves up that reminder......
