It's failrly simple to understand that what we are witnessing here is that one main investment buyer continues to buy. Didn't see the last short report but the mid-November one showed about 70,000 Probe shares are short.
The price location at just above .50 is a buyer's paradise and a potential short seller's nightmare. Have seen tax loss selling dribbling in providing the buyer and shorts shares.
In a basic news starved envorinment and in the in between time of drilling results continue to expect the trading volume to contine to be on the mild to low side.
