Bulk & Block Deals with Named Counterparties
Daily-refreshed list of bulk and block deals on Indian exchanges, including the name of every counterparty — FIIs, mutual funds, insurance companies, promoters, HNIs.
Bulk and block deals are large trades NSE requires to be disclosed — a bulk deal exceeds 0.5% of a company's shares; a block deal is a pre-negotiated large trade in a separate window. They reveal named institutional buyers and sellers. Strota lists today's biggest deals with counterparties, updated through the session.
When a global investment bank buys 2 million shares of a stock, or when a domestic mutual fund sells ₹500 Cr of another, that information is publicly disclosed to the exchange the same evening. Most retail traders never see these disclosures — they're buried in raw text files in public exchange archives. Strota pulls them daily, classifies the counterparty (FII / Mutual Fund / Insurance / Promoter / HNI / Other), and presents them as a clean table sorted by transaction value.
Knowing which institutional name bought what is one of the highest-signal pieces of information in Indian markets, because these players have research budgets you don't.
Bulk deals vs block deals — what's the difference?
Bulk deals are transactions executed during the normal trading window that exceed 0.5% of a company's listed shares for that day. They can be split across multiple smaller orders. Exchanges require disclosure by end of the day.
Block deals are large, pre-negotiated single transactions executed in a special 35-minute window each session — 8:45-9:00 AM and 2:05-2:20 PM — at prices within a +/-1% band of the prevailing market price. They're disclosed the same evening as well.
Both are public information. Both name the counterparty. The combined list of bulk + block deals is what most institutional-flow tracking is built on.
Counterparty classification
Strota tags every counterparty into one of six categories based on substring patterns:
FII — Goldman Sachs, Morgan Stanley, Citigroup, JP Morgan, Marshall Wace, Plutus Wealth, Nomura, BNP Paribas, BlackRock, Vanguard, Fidelity, and ~30 other known foreign institutional names.
MF — anything containing 'Mutual Fund', 'AMC', 'Asset Management'. HDFC MF, Quant MF, SBI MF, Edelweiss, etc.
Insurance — LIC, life and general insurance companies.
Promoter — entries flagged as promoter holdings or labelled HUF / Family Trust.
HNI — known high-net-worth individuals (Rare Enterprises, Abakkus, Ashish Kacholia, Dolly Khanna, etc.).
Other — anything that doesn't match. Usually retail HNIs or family offices.
The category badge on each row makes it easy to scan: 'Who did the institutional buying today?' is one glance, not a research project.
Why following named deals beats following aggregate FII flow
Aggregate FII cash flow tells you 'FIIs net bought ₹500 Cr today'. It doesn't tell you in which stocks. Bulk and block deals tell you exactly which stock saw FII buying and from which fund.
A stock that saw Quant MF + Nomura FII + Smallcap World Fund Inc all buy on the same day, even if the aggregate FII number was negative, is a much stronger smart-money signal than a stock that simply happened to be in the index everyone bought.
Strota's institutional-streak detection runs on top of this data: it flags stocks where institutional players have been buying or selling on consecutive sessions, with the counterparty names visible.
Key takeaways
- Every bulk and block deal the day it's disclosed — full counterparty name visible.
- Auto-tagged by category (FII, MF, Insurance, Promoter, HNI, Other) for fast scanning.
- Deduplicated: deals reported in both bulk and block lists are merged into one row.
- Drives the institutional-accumulation-streak detection (multi-session smart-money signals).
Frequently asked questions
How often is this updated?
Every 15 minutes during the dashboard's refresh cycle, but deals are only published after market close, so the freshest data appears in the early evening.
Do you cover both major exchanges?
The current version focuses on the primary exchange's deal feed. Secondary-exchange deal coverage is on the roadmap.
What's the minimum deal value shown?
Strota's deals view defaults to deals >= 1 Cr in value, sorted by size. The full underlying list (including smaller deals) is persisted to enable historical streak analysis.
Why are some big names like 'Smallcap World Fund Inc' classified as Other?
The classifier uses substring matching against a list of known FII patterns. Some genuine FIIs slip through if their name doesn't contain one of those substrings. The list is extended over time; you can suggest additions via GitHub.
