I am a bit contrarian on the regulatory significance of the first clock stop. At Day 120, Anavex is likely to receive a List of Questions, and the company will respond with its answers, concluding the clock stop. At that point, we don't really yet know whether the answers are going to satisfy the EMA or not. That's answered on Day 180 when the EMA could present us with a List of Outstanding Issues, i.e., items that are still unresolved by the answers to the first clock stop.
We should nonetheless have some clues as to how things are progressing. Was there a first clock stop? Was there a second clock stop? How long did it take Anavex to respond to the LoQ?
Despite the (low percentage) uncertainties inherent in the current process, I do expect the share price to rise during this period as the time for the EMA approval/disapproval recommendation draws closer and the likelihood of an approval looms over the market.
