13g just released. A fund just sold about 400k of their 500k+ shares. Not sure if they are allowed to get a premium price after hours, but, if so that might have been it. EW needs 50% of shares. They may have negotiated a good price for theirs. It does mean fewer shares for shorts. If they didn't sell the remaining 160+k shares because they were on loan, shorty may be in trouble.
