Can someone please explain?

I was listening to a podcast that talked about how quants have figured out how to effectively use 0DTE to edge markets higher while also compressing vol by hedging out delta and gamma at the last hour of the trading day. I assume Broker-Dealers also have to execute on their end as well and hedge out or act as a dealer which may or may not push the markets up as well. If you mix in investing psychology too, this could prompt retail to chase.

Can someone explain this further and how it works and if this is the crux for the rallies this year (aside from A.I chasing/more of a stable backdrop with inflation coming down and FED sort of being done w their job). Really interested to learn more about this. Thanks!

The podcast was called "On The Tape". They briefly mentioned it, but didn't go too in depth on it so I wanted to ask it on here. Overall, the podcast is generally more markets focused than quant focused. They're also bearish on the markets than most people a good amount of the time haha 

Are you a fan of Flirting with models? Might give it a listen
