Agreed on both points, but with caveats.

Well over 90% of the OS is held by institutions and thus the float is small and prone to exaggerated moves, especially to the downside when selling is sometimes forced by margin calls or stop limits. (Buying is rarely forced, but in an index it would be to a degree.)

Rebalancing has had an effect from time to time, but not so much here since in a rebalance scenario selliing would normally be provoked by profit taking when the position in a portfolio gets over-sized and needs trimming. Not the case here obviously.

I do think and hope it was a pre-arranged deal with an appropriately cheap pps. We'll likely find out at the next conference call.
