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:

Block deals are placed within ( + or -) 1% of the Block Reference Price.
Block reference price is determined in 2 ways:
The previous day’s closing price for the morning trading window.
Volume-weighted average price (VWAP) of the stock between 1:45 to 2:00 PM for the afternoon.
A transaction involving at least 0.5% of the total listed shares of a company is a bulk deal. Unlike Block deals, bulk deals happen during regular trading hours and are visible to all the market participants.
The broker is required to inform the stock exchange details like the amount of the transaction, deal participants and other required information.
Can a bulk deal also be a block deal?

Yes, the parties can also carry out the bulk deal as a block deal if it meets the requirement of both the deals.
Requirement for a bulk deal:
If the transaction involves 0.5 % of the shares of a company

Requirement for block deal: Deal value is Rs 10 crores, or the number of shares traded are more than 5 lakh
A lot of investors track these bulk and block deals closely to keep track of what famous investors are buying and selling. Some even blindly buy & and sell just because some well known investors bought or sold.
One point to keep in mind is that for every big investor buying a particular stock, there is also a big investor selling its position in the same share.
Bulk and block deals data contain a lot of noise, and copycat investing can be pretty risky. You need to have your own thesis for buying or selling something at the end of the day.
These deals indicate corporate interest and may cause prices to fluctuate in the short term.

However, investment decisions should not be made based on indicators alone, but also based on fundamentals.

Recently, the @CNIL issued a decision regarding the GDPR compliance of an unknown French adtech company named "Vectaury". It may seem like small fry, but the decision has potential wide-ranging impacts for Google, the IAB framework, and today's adtech. It's thread time! 👇

It's all in French, but if you're up for it you can read:
• Their blog post (lacks the most interesting details):

• Their high-level legal decision: https://t.co/hwpiEvjodt

I've read it so you needn't!

Vectaury was collecting geolocation data in order to create profiles (eg. people who often go to this or that type of shop) so as to power ad targeting. They operate through embedded SDKs and ad bidding, making them invisible to users.

The @CNIL notes that profiling based off of geolocation presents particular risks since it reveals people's movements and habits. As risky, the processing requires consent — this will be the heart of their assessment.

Interesting point: they justify the decision in part because of how many people COULD be targeted in this way (rather than how many have — though they note that too). Because it's on a phone, and many have phones, it is considered large-scale processing no matter what.
“We don’t negotiate salaries” is a negotiation tactic.

Always. No, your company is not an exception.

A tactic I don’t appreciate at all because of how unfairly it penalizes low-leverage, junior employees, and those loyal enough not to question it, but that’s negotiation for you after all. Weaponized information asymmetry.

And by the way, you should never be worried that an offer would be withdrawn if you politely negotiate.

I have seen this happen *extremely* rarely, mostly to women, and anyway is a giant red flag. It suggests you probably didn’t want to work there.

You wish there was no negotiating so it would all be more fair? I feel you, but it’s not happening.

Instead, negotiate hard, use your privilege, and then go and share numbers with your underrepresented and underpaid colleagues. […]
