Their is really no telling how how the investment banks will be able to take this market. The futures are a magic pill that enables the market to gap open and push higher with very little effort overnight. Without the futures, we would be no were near these current levels. How many specialists will gap open their stocks today simply because the futures are up.
The investment banks, fund families and other financial institutions are using (index) futures quite widely in their baskets and products for their customers. Your post is quite uninformed.
