I think the reason for the move is pretty simple. There is a lot more likelihood of good news coming soon than bad. Major players are shifting sides. And the stock should be higher anyway. I don't expect any major announcement or anything today. But it's coming soon. And everybody knows it.
There were 2 articles from SA in the past 2 days giving valuation models for ARNA.
The last time ARNA moved up >10% after 2 wees of being hammered, we put out a pretty comprehensive look at the ongoing rumors and 7 factors likely to move the stock in the near term. There's not much left to say really. The investment thesis is playing out. Every day that goes by is a day closer to DEA putting out their scheduling opinion. Every day that goes by ARNA presses more pills in switzerland. Eisia trains their sales team, and potential EU/ROW partners make their inquiries.
