Don't have time to keep up with more than the main thread, but looks like I was summoned here!Question for @FrankSG and/or @generalenthu :
First, thank you BOTH for your generous contributions to the board! Frank, I've read all of your blog posts, and I make reference to your models often. Generalenthu, I've referenced your delta hedging tables a few times before, and I always pay attention when I see either of you post.
Yesterday, I was playing with Frank's new S&P Inclusion model (Gosh-darn thanks again Frank!), and I'm curious about the inputs section. In particular, I can't figure out how to estimate potential Total Delta Hedge Inventory for price moves larger than the 100pts represented in Generalenthu's super-awesome tables.
My feeling is that we’ll see varying conditions between now and the inclusion date, and I’d love the ability to keep my inputs current.
The range shown on the tables usually provides plenty of headroom, but during the inclusion period I’d love to be able to assess a wider range, similar to this section from Frank’s newest post:
I understand if you’d rather not share this info publicly, so thanks regardless. You’ve both already been a huge help!
Side note: I do remember some discussion here when @generalenthu first presented these tables, but I wasn’t able to dig it back up. If there’s existing discussion on the methodology, and you’d rather just point me there, I’d appreciate that as well.
Thanks again!
Go Go TSLA Longs!
I am just rerunning the numbers for these large moves offline, as I don't want to mess with the automated job that updates the online tables.
Perhaps I could post them on Twitter or here till the inclusion is behind us.
That said there is one other adjustment I am eyeing. The numbers I gave @FrankSG for his model are inclusive of all expiries for an instantaneous stock move. Now that we have more clarity on the inclusion date, I can perhaps ignore 12/4 and 12/11 expiries, which would be more representative of what the market makers need to hedge as we get closer to inclusion.
I will look to publish Thursday AM as I have numbers from last Thursday and it will be a good week over week comparison.
