The SEC still believes there is about 0 shares short RGRX. Today, 174,000 traded short. when the news first hit, there was one large block buy of 170,000 shares at 0.2440. That could have been the large "short cap RGRX"….but when that got taken out in one fell swoop…they got more careful. It works out to about 18% of volume today shorted.. But with 973,000 traded there was enough volume for some buy/sell/buy/sell. Who knows if they bought some back. But if they did, I doubt it was 174,000 worth..MM's are still lareg short here..and it is unreported (legally).
