How's your buy and sell timing?

This is a thread about nothing if you are truly long-term investing, which I am on 80%+ of my stocks.  I swear 65% of the time I move a stock it moves 1/2% or more in the wrong direction within 48HRs.  

One of my investing rules is always try to avoid doing what you wish you had done yesterday, or last week.  That seems to help avoid the problem somewhat.
