The only thing es has to follow is its underlying s&p 500 the index, maybe this is why es can be so trendy sometimes.
Of course ES follows SPX or SPX follows ES... because they're the same... future and underlying...
if one wouldn't follow the other you can do some serious stuff...

So I'd say it's only a "fairly silly" thread title, myself, not "the silliest ever".![]()
