I do independent research on EA topics. I write about whatever seems important, tractable, and interesting (to me). Lately, I mainly write about EA investing strategy, but my attention span is too short to pick just one topic.
I have a website: https://mdickens.me/ Most of the content on my website gets cross-posted to the EA Forum.
My favorite things that I’ve written: https://mdickens.me/favorite-posts/
I used to work as a software developer at Affirm.
Can you explain? I see why the implied vols for puts and calls should be identical, but empirically, they are not—right now calls at $450 have an implied vol of 215% and puts at $450 have an implied vol of 158%. Are you saying that the implied vol from one side isn’t the proper implied vol, or something?
