Part 4: Understanding #OptionsBasic for #Nifty #BankNifty
In previous threads, we understood Intrinsic/Extrinsic value of options, how to achieve greek neutrality, risk management and how to define cheap or expensive options. Now

What Is Historical Volatility (HV)?
...1/n

@rohit_katwal Historical Volatility is a statistical measure of the dispersion of returns for a given security or index over a given period of time. This measure is calculated by determining the average deviation from the average price instrument in the given time period.

2/n
@rohit_katwal Using standard deviation is the most common, but not the only, way to calculate HV. The higher the historical volatility value, the riskier the security. However, that is not necessarily a bad result as risk works both ways - bullish and bearish.
3/n
@rohit_katwal What it does measure is how far a security's price moves away from its mean value.

For trending markets, historical volatility measures how far traded prices move away from a central average, or moving average, price.

4/n
@rohit_katwal This is how a strongly trending but smooth market can have low volatility even though prices change dramatically over time. Its value does not fluctuate dramatically from day to day but changes in value at a steady pace over time.

@rohit_katwal How Implied Volatility Affects Options?
Implied volatility represents the expected volatility of a stock over the life of the option. As expectations change, option premiums react appropriately. Implied volatility is directly influenced by the supply and demand

@rohit_katwal of the underlying options and by the market's expectation of the
share price's direction. As expectations rise, or as the demand for an option increases, implied volatility will rise. Options that have high levels of implied volatility will result in

@rohit_katwal high-priced option premiums. Conversely, as the market's expectations decrease, or demand for an option diminishes, implied volatility will decrease. Options containing lower levels of implied volatility will result in cheaper option prices.
...8/n
@rohit_katwal This is important because the rise and fall of implied volatility will determine how expensive or cheap time value is to the option, which can, in turn, affect the success of an options trade.

So to BUY or SELL options
If HV>IV=buy options
If IV>HV=sell options
9/n
@rohit_katwal If HV > IV = buy options - We assume that IV is less and will increase and value of bought option will increase.
If IV > HV = sell options - We assume IV is high and will decrease and value of sold option will decrease.

It has to be used with direction.

@rohit_katwal Remember in #INDIAVIX thread we learnt that volatility is Cyclical, Persistent and Mean-Reversing. Here are some more resources to learn about the terms used.

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

Before I begin, it might be worth explaining the Malay conception of the spirit world. At its deepest level, Malay religious belief is animist. All living beings and even certain objects are said to have a soul. Natural phenomena are either controlled by or personified as spirits

Although these beings had to be respected, not all of them were powerful enough to be considered gods. Offerings would be made to the spirits that had greater influence on human life. Spells and incantations would invoke their


Two known examples of such elemental spirits that had god-like status are Raja Angin (king of the wind) and Mambang Tali Arus (spirit of river currents). There were undoubtedly many more which have been lost to time

Contact with ancient India brought the influence of Hinduism and Buddhism to SEA. What we now call Hinduism similarly developed in India out of native animism and the more formal Vedic tradition. This can be seen in the multitude of sacred animals and location-specific Hindu gods
