This friend had trouble making money in options though he was directionally right. Let us see how a basic understanding of greeks would have helped him, This thread will be about two attributes of option pricing, extrinsic value and theta

An option has two parts, intrinsic and extrinsic value. Think of a pack of Lay's potato chips. When you buy and open the pack, what you find is some chips and a lot of air. Intrinsic value is the chips, extrinsic value is air

Let us stop for a second here. When our friend was buying the 31700CE, he was buying pure extrinsic value, i.e, AIR
He has a second problem, theta.

What is theta ?
Watch this example for theta. These are actual calculations of greeks

DTE = Days to expiration. Watch that the theta decay curve is not linear, it speeds up as we approach expiration
https://t.co/wWYA331uQi
Theta decay starts to accelerate at 13 DTE. From 6DTE, it justs accelerates like crazy . This is true for all options
So our friend in this example was hit by a double whammy ( triple actually, due to vega, but vega on a later day. Explaining vega will confuse if you are a novice).
1. He was playing pure extrinsic value
2. He has a high theta burn rate so close to expiry, the highest
Hence, his 31700 call was not moving up fast. It was continuously losing theta. Being an OTM option with pure extrinsic value, the theta burn was very high
So what is the solution ? An options buyer has to negate theta burn to a certain degree. Best way ? Should have used a bull call spread. What you lose due to theta in your bought option can be somewhat covered by theta gain in the sold option
I can or anyone knowing greeks can make a position almost theta neutral thru spreads

THIS IS HOW GREEKS HELP YOU !
I understand that when one opens an options book, the maths seems daunting. It's supposed to be, Black and Scholes won the Nobel prize for making that formula 😃 To be very frank, if you ask me the total maths, I will also have trouble explaining
So, focus on the graphs. Using graphs is the easiest way to understand options. Whatever strategy you use, plot it graphically and play around with vols, DTE and direction

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 ?
https://t.co/VOkAwGRsHL


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

We know that elite institutions like the one Flier was in (partial) charge of rely on irrelevant status markers like private school education, whiteness, legacy, and ability to charm an old white guy at an interview.

Harvard's discriminatory policies are becoming increasingly well known, across the political spectrum (see, e.g., the recent lawsuit on discrimination against East Asian applications.)

It's refreshing to hear a senior administrator admits to personally opposing policies that attempt to remedy these basic flaws. These are flaws that harm his institution's ability to do cutting-edge research and to serve the public.

Harvard is being eclipsed by institutions that have different ideas about how to run a 21st Century institution. Stanford, for one; the UC system; the "public Ivys".
