I'm not convinced that the sell-off is accounted for by the delisting only. Given the share-price, the delisting would be seen as a non-event by anybody familiar with penny stocks. Further, news of delisting was available since friday, yet the share-price held until the afternoon, and then the bottom dropped out. Maybe one seller set off an avalanche, with nothing else behind it. At this juncture though, I'm surprised that there are still weak hands holding shares in this stock. My concern is that there's news behind it. We'll see. This is the second heavy volume day that doesn't make a whole lot of sense.
