#AirPollution, measured by annual PM2.5--particles finer than a human hair--reduced in bigger cities such as Delhi & Varanasi but increased in smaller cities such as Fatehabad & Moradabad, finds a @CSEINDIA analysis of 26 cities. Follow the thread for insights:

In many cities in the upper Indo-Gangetic plains, avg PM2.5 levels were above 2019 levels. #AirPollution in Fatehabad, in northern Haryana, deteriorated the most, with PM2.5 levels increasing 35% from 2019
The %age of PM2.5 in the coarser PM10--which determines air toxicity--was in the high 40s in Oct & remained so in Nov, averaging 55% in Amritsar, 48% in Chandigarh & 53% in Patna. It reached 64% in Amritsar, 69% in Chandigarh & 62% in Patna during #Diwali2020
#AirPollution reduced the most in Sirsa, 40km from Fatehabad, with a 44% lower avg PM2.5 2020 level vs 2019. This massive variation can’t be attributed to meteorology & has to do with local factors such as stubble burning, Avikal Somvanshi, CSE prog mgr, said in a press release
PM2.5 avg in Nov 2020 was 310% higher in Fatehabad, 104% in Agra and 57% in Kaithal, compared to November 2019
Home to over 600 million, the Gangetic plains host four cities--Kanpur, Faridabad, Gaya and Patna--that were the most polluted in the world in 2018, according to the WHO, we reported in March 2019:

“Today, more than 76% of the population lives in places that do not meet Indian air quality standards,” Sagnik Sey, coordinator of @CERCA_IITD told us in a Nov 2019 interview: https://t.co/4DjtJGbv3l
In India, the PM2.5 average during the 2020 summer & monsoon was lower compared to 2019 due to #COVID19. But reopening of the economy coincided with the onset of winter in India, which trapped #pollution, leading to a rise in PM2.5 in October, the @CSEINDIA analysis notes
In Amritsar, there were 33 days that met the air quality standards in winter 2020 vs 41 in 2019. In Lucknow, there was not a single day that met the air quality standard after October and 19 days of ‘severe’ or ‘worse’ air quality, up from 5 such days in 2019
#Airpollution killed ~116,000 infants in India within the 1st month of birth. More than half of these deaths were due to PM2.5 in outdoor air, we reported in October 2020:

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.
