AGEN is a troubled company, don't chase the stock.
So many times this company has announced promising news over the years, only to see the stock continued to slide and languish in the $2-3 range. Sadly this time appears to be no different. A bunch of people will chase this premarket, and by days end the stock will be flat to down a couple percent. Until an approved product comes along and revenue starts flowing, nothing will change. That's years away.
