Retail buyers are spooked by the technicals. Unfortunately, the shelf sale and pps drop has tarnished the stock and Vitaros is not today's story. It will be again, but not today.
Short sellers can easily work the price down (while covering a little) in this climate. I think they are doing so to establish a lower base as a buffer against any good news. They also know they cannot cover wholesale without driving the price up.
The drivers that will turn this around are well known. The main near term drivers are announcement that Abbott is selling V in Canada and European V approval (hopefully).
