It's like this company doesn't exist this week. I briefly look at the big gap bid/ask and no volume action each day. It is extremely odd for there to be no buyers or sellers. I even put limit orders in at bid just to see if they get filled and they never do for the last 3 days in a row.
It's been that way for a few years now, I don't get it either. The vibe from the PRs and Conf calls is fabulous of late and I believe in their CEO. I fully expect the stock to reach the 7s over the next 6 - 9 months. It is simply too cheap at these levels.
