ความผันผวนของตลาด SPX - เราพลาดอะไรไป?

Seems like a pretty standard Friday afternoon fade to me. Happens all the time when there's no major catalyst. Plus, 7500 is a big psychological level.

I wouldn't be surprised if it's just gamma hedging. With it trading at 60% earlier, a lot of people were probably long calls, and as it drops, the market makers are selling futures to stay delta neutral.
