Most likely the trade occurred or was negotiated during the day and was just recorded in the after hours. There isn't enough volume in the after hours to support that without a large pps move.
Interesting that all shares are loaned out at fidelity and the current annual rate to borrow is 19.5%, that's up from about 7% a few weeks ago.
Contrary to the popular opinion, the larger brokerages don't pull shares from lending just because of a GTC limit sale order.
How do you find it hard to buy? I just opened up my account, typed in 500 into the "shares" column and picked up another 500 shares in 1 minute. It was pretty easy.
yeah it's been a wild ride in the biotech sector for the past 6 months. I've got IMGN and ARIA besides KERX, and they both like to move 5% each day.
KERYX has a tiered royalty structure. It was 5 M upfront payment, 55 M in milestone payments, and a tiered double digit royalty structure in the press release. I later found that analysts expect 13% royalties at peak sales, so about 10 M dollars per year.
