This happens to me too. Don't dwell on it. Makes it seem, to me at least, as if it happens more frequently than reality.Im tickled pink that I dumped my employee owned Wells Fargo stock early this week. NOT!
It's only gone up another 10% two days later. Let's see what happens today *LOL* Talk about timing, oh well, would have, should have, could have, I always hated this stock. I still did ok, but was waiting for one more leg up and just missed it!
(im only posting this because its nice to hear the not so great successes once in a while, we tend to hear only the good ones)
I readily admit I was lucky with NYCB. With a run up, with such a stock, in 10 days, I'm out yesterday. And today it's down. Point is we overemphasize both directions. Makes one a lousy investor.
Look at the reasons you bought and sold. Look at the reasons why it went up or down. Even if not a technical trader. there is something tiny bit to be learned.
