The question does bring up a point I have occasionally wondered about.
It is, since there is no underlying you can trade, do the MMs and
others who do dynamic hedging, use an approximation like SPY to do the
hedging? I know there are some index options where there is no
approximation to the index (XAU nay be an example). What do the MMs
there use to hedge?
