just popped in my feed and seems more technical than his other recent works. some good co-authors too. apparently he made available a free pdf version https://arxiv.org/pdf/2001.10488.pdf haven't read yet, but figured it was worth a post
Skimmed through it, do you need a masters in statistics to get all the technical aspects in the book? I am STEM educated but didn't major in statistics
All that is a good read if we get into a complete lockdown again but all we need is ONE statistic: the probability of that Fat tail event happening. I only skimmed through the first few pages and he talked about the consequences of the Fat tail. I can't understand why he chose to dwell on that. If it's a Fat tail, it will be an extreme event. All extreme events will have dire consequences otherwise they wouldn't be qualified as "extreme event" and wouldn't be happening at the "tail" so talking about the consequences is irrelevant. It will be big, we get it. The crux of the issue is how likely it will happen, the probability of it happening. Yeah the consequence of Iran launching a nuclear missile at United States will be fatal for the entire planet but what is the probability of that happening? That's what we need to know to decide how much resources to dedicate to surviving that "Fat tail" event.
I am not sure probability can be calculated. Oil at -37 not too long ago would be impossible one out of billion, and yet we saw it in front of our eyes. We as traders just need to trade with assumption that severe crap can happen, and trade accordingly.
Just this year alone, how many did we have tails??? They supposed to happen once every 1000 of what ever years. Yet, last 20 years we had so many tails. Risk and leverage - must be controlled and used carefully.
Got it. Thanks. Instead of controlling risks, how about go hunt for tails since they are priced as rare events yet happen quite often, like the 100 year flood that happens every few years?
That’s the million dollar question isn’t it? Buying far out of the money options at a discounted price would be a general framework
