Good call! Unless you REALLY need whatever money your shares are worth, or are confident enough that you can trade it back to value elsewhere faster than this can recover, then you are better off not selling as a reaction to yesterday's disappointment. People are already taking advantage of these lows and buying more, and combined with the pending financial report, it shouldn't take long to stabilize, or at least provide a much less damaging exit point! Rather than sell, invest more, in a fifth of gin and a long walk in the woods and check back here in a few days or whenever.
