Volume has been well under the average daily for a number of sessions. This probably helped those shorting the stock. But the Short Interest increased significantly as last reported, and that will fuel advances once the buying picks up.
On the brighter side, the longer ACAS dawdles around the current price, the more opportunity exists for management to be buying more ultra-cheap shares. We win either way- The only difference is how much and how fast. In this situation slow is good and acceptable to me..
