Doc Logic, the non-naked short interest is all loans per agreements. So I assume you are talking about naked short shares, correct?
These are reported under reg-SHO. The trigger for being put on the "bad boy" list is .5% of the company shares. So for NWBO the trigger is a over 1.5M shares.
I have never seen NWBO on this (though they might have been sometime). I have seen some numbers that showed the count briefly spiked, but never stayed high long enough to trip this.
Seriously 1.5M shares? About $250K?
I doubt the financial world is coming to the for such a pittance.
