I think, it is quiet obvious. They announced a Public Offering and the share price went down. Those who sold are longterm shareholders, that are frustrated and this NEWS was the trigger for them to finally sell.

Announcing a Public Offering without naming the price and connected with a bad communication leads to understandable frustration. That's what happened. Maybe from this downtrend hedge funds profit and even fuel it. But the basis is simply an understandable investor fatigue. I also feel this investor fatigue, but still hold strong to my shares.
