Re KDR Chart, page-1448

It doesn't happen all at once Rupfel. It is all pre planned for lack of a better term. The appointed broker gets into action well before the Rebalance Date. They can work out in advance who is going in and out. They have numerous methods to buy the shares in the lead up. They have methods and accounts like "in-house stock" or whatever they designate them to buy cheap sell rich to the fundies putting in the orders. They can even sell short to fill the bids on the anticipation they can drive the SP down later on to refill the loaned FPOs. I call all this type of preparatory work 'front running'.

Other types of front runnning is done by players who want to be sellers to the managed funds in the rebalance. They will stock up on the dips, or even drive the dips to do so , to build a block for sale to the fundies. This can often be transacted well before rebalance date through the means of the broker's 'dark pool'.

What I describe is very basic and superficial. The reality is much more complex of course, especially when looking at the fundies who want to unload on a rebalance event.
