Stocks Slammed At Cash Open As Quad-Witch Weighs On Sentiment

US equity markets surged higher as Europe opened overnight, but as the US cash market opened, stocks broadly speaking puked as the effects of options expirations started to impact direction…

Small Caps are bouncing back but S&P, Dow, and Nasdaq are all down notably as SpotGamma warns that post-opex, next week, we could see the S&P unpinned from 3700.

Additionally, SpotGamma warns, at least 40% of this rolls off on todays expiration. This could create a bit of single stock pressure on Monday as hedgers adjust.
