Two things:
1. that does not represent retailer shorting or naked shorting...it represents intraday MM shorting, which is covered within microseconds. I've seen it for myself, when my buys show up on that list when I'm the only volume! The only thing that number can tell you is how thinly traded the issue is, and how hard the MMs have to work to make the market.
2. Even if I'm wrong, I have never seen a stock recover from real naked shorting....they will never cover, and if ( I used the word 'if' reservedly ) this is a scam, they will never have to cover.
...they made a mistake on BCIT, but that is another story...
