"What often happens in these cases is that the big investment funds will take positions in the various commodity indices which are then required to purchase a basket of commodities according to their weightings in the respective indices. That of course then witnesses big buying by the guys that run the indices. There were very few markets that were down today in the commodity world and among those that were, most of them managed to come back well off their session lows as that index related buying took place.
This is long term oriented money in contrast to some of the hedge funds who will play both the long side and the short side of the market; these funds are �long only� funds. They buy and sit tight. Whether this phenomenon will be repeated over the course of the next few days is difficult to say but it does give one a preview of what can happen to these relatively small markets when a wall of money hits them. Heaven help the shorts!"
