After initially following someone else's trades a couple of times (and not getting out at the peak, thinking whatever it was would go much higher), I started to use other people's trades as just pointers to stocks that I normally wouldn't have heard about. So, I kind of learned that lesson.
Suppose my biggest trading problem is that sometimes I'll get in at what I think is a low and then begin to really like what the company does, prove to myself that the stock is undervalued, and hang on through bitter dips until I totally lose faith that the stock will ever come back. Don't do this as often as I used to, but I still treat certain stocks this way, or maybe those stocks treat me this way. Can't figure it out. Ha!
