Based on the dd I have done it appears that DHSM has been heavily manipulated, through the use of a variety of regulatory loopholes and retained liaisons.
I believe they are either near completion or have completed their work, thus we are now seeing the pps begin to rise. The chart below represents the pps decline since the last reverse split (4/29/11). As you can see it has significant upside potential.
In addition the company should be releasing some significant news about a JV partner and their casino site.
