Nice post because of nice historical record it establishes... BUT, many of those examples of GAPS have since filled.
My RULE would be this -- if you are a long term investor you should ALWAYS fear the GAP, buying after a GAP with the intention to HOLD for a long term is a mistake in a high percentage of cases --- if you are a swing trader, you should trade very cautiously after a GAP, and don't be surprised after three months to see an old GAP fill, when you sense it coming GET OUT and WAIT FOR IT. After all, missing an OPPORTUNITY in the market is no big deal if you avoid being wrong a high percentage of the time by passing. There are more opportunities than you will EVER have money to capitalize on them, so PASS when there is a threatening factor involved and look for something else.... or BE VERY CAREFUL.
