I did a quick volume estimate from the beginning of the drop in August and up to date seems they are still in hand 10-13 billion shares in hand at an average of 1950-60. I'd assume before any major drop they would liquidate those higher unless they are certain they will get there later. Not sure if you can buy SPX shares like spy shares but if so that's what it would sum up to. I guess I could still drop if they are hedged who knows.
