We are tanking because people think we are going to run out of money and go to biotech heaven (or hell, depending on your perspective.) Overall, investors are quite skittish so this decline doesn't surprise me.
Also, we are tanking because people think that a reverse split is a "done deal." While I agree that a stock split is meaningless in terms of valuation etc., stocks often decline reflexively when a company announces a reverse split. In other words, people sell because they believe the price will go down.
We could see the .40s unfortunately but it would be a great buying opportunity.
