The light volume is the reason for the pps doing a slight downward drift within a overall range of $2+ to $2.40.
As long as the overall wary market continues to correct the access from the previous remarkable rally[correction now near 10%]no stock ckgt included can expect much "new" buyer support until volume starts to increase.
A lot of these would be new buyers are probably techical traders while most now holding ckgt are doing so for fundamental reasons.
The ability of ckgt to hold within its trading range on decreased volume is a show of strengh in a down market.
However only a news event or change in overall market prospective will bring the needed volume back to raise the pps closer to the true value it will some day reach for those willing to hold thru these boring trying times.
