I keep checking to see if RVX is on the buy-in list for delivery failures (naked shorting) but I haven't seen it since that one day a few weeks back when it was I believe 10 or 13K or so.
Short interest update should be out sometime before this week ends. With quest showing the borrow rate at 48% as I look right now I don't suspect there's been any meaningful drop, and perhaps its gone higher.
