Warning! Gaps often get filled in the twinkling of an eye and stock price immediately takes off., sometimes to the stratosphere. Unless you have time to watch the ticker all day every day, play another game that is safer like trying to poke sticks in your eye. It has also been noted that gaps are not 100% certain to fill. Betting on gaps to fill is a low risk/reward activity.
The gap may have to wait for a while.The sentiment in Washington on the cliff debate is the driver of the market.Shorts may not be bold enough to take positions as a deal is made.There will certainly be a deal soon and i suspect the market will rally.
Today and yesterday was short covering, IF it goes down tomorrow to test 172, and that would mean the gap will be filled sooner than later. If this does not happen tomorrow, than your perspective is the correct one.
