What has you so upset, the share price or some fundamental change in the company's position? I'm not aware of the later so it must be the share price in which case stop worrying about the herd!

All that's happened is that a (likely pre-IPO) investor has cashed out and that could be for any number of reasons, quite likely to offset losses made elsewhere on the market or because their CGT 1-year limit just expired. Focus on the fundamentals, if those haven't changed ignore the day to day movements, a stock this early in the game can make dramatic moves in *both* directions.
