Two things could be driving it (this is just a guess). First, we know AHRO wants to do a secondary offering by July 1. Second, management has an incentive to keep the share price as low as possible until they do the secondary offering. Based on that, I would assume management will try to pump up the stock within the next week. A couple days after, they will follow up with a secondary offering after the market closes. I think they will announce something before the market opens on Monday or Tuesday that will cause the price to rise significantly and announce the secondary after the market close on Wed or Thurs. That's what I would do given the management incentives in place.
I think it is a lot of the small share owners getting nervous to see the price drop so it perpetuated it. There hasn't been any news for a while so that doesn't help. I'm still holding on. Phase 1 results should be any day/week and initiation of phase 1b will be any day, both positive results. The concern is not being above the $3 mark that is needed for uplisting, the reason they reverse split in the first place. I thought it was a bit pre-mature prior to releasing news which then has caused the price to drop more.
