Quote from optionatrix:
Does this have any practical impact for the retail trader?
If the news was monthly SPX expiration to be moved to Friday evening (which was what I initially thought the thread title meant), then I'd be all over it.
Quote from FrankSlaughtery:
you don't want to use SPXPM?
in general i don't really think this is news. first of all you can only exercise options on friday until 530 est (well i've never heard of anyone doing it later).
