If you wait until tomorrow, the price will go up another 5 or 6 points at the opening. Don't expect this one will drop like all these internet related stocks. They don't have decent earnings to support the price and the price will come down soon or later.
There is never a bad time to buy PFE stock and do not get caught up in the gloom messages on the board. PFE will hold it's value over the long run. Do not loose sight of our pipeline. Only buy what you can afford and take care of the home front,PFE will take care of your future. It has in the past and will continue to do the same in the future. My advise to the young investors is to just check the percent gain for the year to date. Close your eyes and check out PFE in another four or five months and you will be greatly surprised.
I think the stock will probably still climb to a newer high by end of day, but there is a good chance that it will retract what it gains later today on tomorrow. So it might end up being about the same either way.
