That is an interesting link.
I don't know if anyone else finds that the more they trade the less time they devote to reading and/or listening to gurus. I used to read all the magazines and the wsj, ibd, etc. Now I skim and still have a few shows I like, but would rather just look at my charts and skip the news.
On the psychological side, it is tough as hell to just sit on your hands. Right now, I can't help but thinking I wish I was longer. And two months ago I wished I owned nothing and wanted to be short.
Guess that is why it's called money.
