Trying to sell and buy back... I tried do ONLY do that for over a year. Long story short, I cashed out 5-10% gains and missed out more than a few 100% to 200% gains -- I'm looking at you VISA, AAPL, and GOOG.
We need crystal balls.
wow.. today has been one hell of a day.
thank god I dollar cost avg'd.
my original plan was buy at $x, sell at X * .9, buy at X*.9*.9, sell at x*.9*.9*.9, buy at x*.9*.9*.9*.9, etc
basically sell when it drops 10%, rebuy when it drops another 10%, rinse/repeat.
I would have been out $20k if I did that. after the 3rd time I sold, I would not have been able to execute the buy because the stock took off like a rocket.
instead I bought everytime it dropped 10%.
I'm still down a little, but will breakeven when it goes up another 10%.
