Anavex Life Sciences Corp (AVXL)

That isn't too hard to figure actually.
The entire bio-tech sector as shown by XBI is down substantially during the same time. Add in the entire market is on the verge of losing 50period support.
Add in the many who want to see AVXL fail and are disingenuous in their negativity. Add in that other than funding there is no company or product revenue for AVXL yet. All of this is quite normal for such an early stage company. Because of these factors and others the volatility is exacerbated.

If an AVXL buyer didn't understand the historical norms for baby bio-tech progression and risk then now they know reality in this sector.
Just the way it works. Commodities, crypto, tech, AI, robotics etc all have periods like this individually and as sectors too.
