IV - A thread
— Subhadip Nandy (@SubhadipNandy16) September 20, 2018
In financial mathematics, implied volatility of an option contract is
that value of the volatility of the underlying instrument which, when
input in an option pricing model ) will return a theoretical value equal to the current market price of the option (1/n)
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
