### Comment:
I think it’s very interesting, how the market is a composite of the stocks it indexes, but the index is affected by support and resistance just as much as the stocks it tracks.

### REPLY:
I’m ashamed to admit I have no idea how this works. Like by design it is supposed to track SPX. Maybe that’s fairly easy to accomplish with a certain structure of options but I always notice when the two diverge either on % change or when SPY isn’t equal to 1/10th of SPX (often) and wonder if it’s possible to have a day where SPX is up and SPY is flat or down due to some big money fuckery
