The question I'd ask myself is 'if I sold, where would I reallocate the capital?'. It might be wise to come up with a compromise, whereby you hold a portion and sell off the rest to move into another stock or asset class to attempt to recoup your losses. This is what I am considering also, depending on the announcement tomorrow. However, it may be too late to exit in an orderly fashion, only the hard results will reveal all.
I took a hit recently on another stock, moved my capital into a few others, since then I've made much more back than I originally lost. Tax issues will factor in, depending on your personal circumstances. Capital preservation is key.
