Can't explain the recent rise in AVR, who make a new type of heart valve. From a low of $4.25 on 5 February to an intraday high of $7.60 today.
I lost patience as trials slowed because of covid. It has a very checkered history of continual capital raises and consolidation of shares.
There has not been any new significant news as far as I can tell. I don't think the new presentation would be enough to cause such a price pop.
I keep setting a higher price alert thinking it couldn't possibly get there anytime soon and it keeps going off (annoyingly as I don't hold it anymore!) and I keep reseting it.
