input in an option pricing model ) will return a theoretical value equal to the current market price of the option (1/n)

Two year back thread on MFI, someone liked this so came up in notifications . Rather than running around 100s of indicators, I have made this my go to indicator under any circumstances and have been using this for years

This question might have rose in your mind too, that why VIX was lower than yesterday despite the huge selloff today.
This is what I think happens . A thread.
What is VIX ?

What is IV ( implied volatility ) ?
Now my explanations. IV is simply demand and supply. IV is back calculated from option prices and not given by the BSM model. When demand for options ( by buyers) are high, IVs will be high. When supply of options ( by sellers) are high, IV will be low.
Now look at this chart. Nifty fut and VIX are plotted together ( red line is the VIX). Yesterday's massive breakdown forced traders to hedge their positions by buying puts ( could be cash holdings, could be future longs, could be sold puts). This excess demand spiked up IVs /VIX

I just finished Eric Adler's The Battle of the Classics, and wanted to say something about Joel Christiansen's review linked below. I am not sure what motivates the review (I speculate a bit below), but it gives a very misleading impression of the book. 1/x
The meat of the criticism is that the history Adler gives is insufficiently critical. Adler describes a few figures who had a great influence on how the modern US university was formed. It's certainly critical: it focuses on the social Darwinism of these figures. 2/x
Other insinuations and suggestions in the review seem wildly off the mark, distorted, or inappropriate-- for example, that the book is clickbaity (it is scholarly) or conservative (hardly) or connected to the events at the Capitol (give me a break). 3/x
The core question: in what sense is classics inherently racist? Classics is old. On Adler's account, it begins in ancient Rome and is revived in the Renaissance. Slavery (Christiansen's primary concern) is also very old. Let's say classics is an education for slaveowners. 4/x
It's worth remembering that literacy itself is elite throughout most of this history. Literacy is, then, also the education of slaveowners. We can honor oral and musical traditions without denying that literacy is, generally, good. 5/x
As someone\u2019s who\u2019s read the book, this review strikes me as tremendously unfair. It mostly faults Adler for not writing the book the reviewer wishes he had! https://t.co/pqpt5Ziivj
