>You haven't looked at the numbers. There's so much option trading that it affects the entire market a lot

The question is "what effect does have?", not "does option trading effect the market?"

That I cannot really tell you - I don't know.

The standard story is about delta hedging (i.e. the buyers are speculators that don't delta hedge, but the sellers do hedge, introducing a lot of gamma into the market, thereby amplifying moves).

My larger point is that in this state of the market one really has to wonder who's ultimately setting the prices.
