I'm surprised too for the reason (who is interested in selling at these prices?) I mentioned that I saw it staying in the 14 cent range. Not that 12.5/13 is so much of a drop, but the volume seems quite large. Dollar wise of course it's not a huge amount (less than $50k), but for DKAM, it's significant.
One possibility (and it's a WAG on my part) is that there have been times in the past when apparent good news has preceded more significant bad news (or at least that's one interpretation). Perhaps the speculation on the MB and the press releases have some stockholders concerned about what's coming next.
If the conference call has been rescheduled as was suggested earlier, it might go a long way to allaying concerns, assuming the information provided was not negative.
