here’s a slightly wonky thread that people who use post-nominal letters will not like: let’s talk about real-time learning in quant-driven strategies and how to do it in practice, because a lot us do this as a result of real-world constraints. its basically TA with a dress-code.
1) volatilities are not stationary but they undergo relatively synchronized regime changes
2) exponentially weighted vols are more responsive to changes in current conditions
4) honestly the numerical methods are just simpler and i’m a dumdum so it makes it easier for me
6) for long-short baskets of like assets it avoids painful assumptions about intercepts (and therefore betas)
instead of weighing long and short baskets with betas, you just use an ewma of your preferred volatility estimator, i happen to really like GKYZ for anything involving leverage or synthetic options like “stops” or “risk-control” implementation

A 🧵on the basics of block and bulk deals.
Block and bulk deals are large purchases of stocks by investment banks, mutual funds, hedge funds, pension funds, FIIs, and promoters. Tracking block and bulk deals can help give you a sense of what these large players are thinking.
A single transaction where shares more than Rs 10 crores or the number of shares traded are more than 5 lakh is considered a block deal.
Block deals are carried out in separate trading windows. This trading window operates in two shifts of 15 minutes each:
Morning trading window from 8:45 AM to 9:00 AM.
Afternoon trading window from 2:05 PM to 2:20 PM
Block deals happen in different windows to reduce volatility and sudden price movements. Given that they are traded in a separate window, they do not show up on the volume charts.
Brokers facilitating the transaction are required to inform the exchange. You can track bulk and block deals on NSE & BSE:

Oh my Goodness!!!
I might have a panic attack due to excitement!!
Read this thread to the end...I just had an epiphany and my mind is blown. Actually, more than blown. More like OBLITERATED! This is the thing! This is the thing that will blow the entire thing out of the water!
Has this man been concealing his true identity?
Is this man a supposed 'dead' Seal Team Six soldier?
Witness protection to be kept safe until the right moment when all will be revealed?!
Who ELSE is alive that may have faked their death/gone into witness protection?
Were "golden tickets" inside the envelopes??
Are these "golden tickets" going to lead to their ultimate undoing?
Review crumbs on the board re: 'gold'.
