Just an opinion, but if I were an Insto, or a Proprietary Trader with quotas to meet monthly, quarterly, annually etc etc, i'd be out too, 20%+ profit in a couple of days and move on to the next trade..
If you're a LT holder, and see genuine value and potential in the company I don't see why you should dwell on one day of moderate selling .. merely an opinion of course.
... please follow my sentiment ;) my hands are out to catch all I can!
