Short interest went down 4 MM shares from mid May to June 28, I had expected more. The volume I had predicted for June 28 (In my post I said June 30 but 28 was the last trading day of second quarter) ended up being split into June 21 (much of this XBI related) and June 28 (Russell related). As predicted by both of us, price did go up once all the re-balancing shenanigans were over.
Good thing we invest in share price and not short interest.
