I have a very large position with Pfizer and I am not flinching. Now may be a good time to sell some of your shares if you want to take a loss for the 2004 tax year but other then that long term things should be fine.
Pfizer has a lot in there pipe line. The current problems with Celebrex has already been factored into the stock price but some of the sheep are still fleeing.
I will add to my position soon. This stock is a bargain right now even if they have to take Celebrex off the market.

of course
