In summary JP Morgan's forecast of the commodity index rebalancing which will done around January 8-9th is:
...we expect the rebalancing to have the greatest impact in gold, COMEX copper, crude oil, gold, and live cattle. We estimate that the rebalancing of the two indices is expected to result in $877 million of selling in gold, $699 million of buying in COMEX copper, $528 million of selling in live cattle, and $523 million of buying in crude oil.
We would expect the impact of the index rebalancing to be felt this week because of 'frontrunning' of the index changes by the big commodity trading desks. Indeed we may find that by the time the changes are realized, the impact may be significantly discounted.

The S&P GSCI index weightings kick-in after its January roll which commences January 8th. JP Morgan estimates about $50 bn of investment into that index...
