Peeker - re TVIN my guess (only a guess) is that the 300,000 shares were likely an institution taking a position in Homeland Defense or a brokerage buying a large block for marketing to their retail accounts. The brokerage in Minnesota that has tracked the stock comes to mind in that regard.
In any case, yesterday's volume was in excess of 500,000 shares and upward pressure continues today. All factors are right for significant move upward. Shortly, canister line will have approval, the helicopter landing targets should be cleared for the military to order (sole source)and the core line tent sales should be picking up with heightened interest in first responder preparedness.
All on top of a rock solid balance sheet, growing working capital, no debt, etc etc.
Stars aligning???
Happy investing!
