Ownership & filings
Research tool · not investment advice. Full disclaimer →
Where insiders — promoters, directors, KMP — put their own money: net open-market buying against selling, in rupees, over 30 and 90 days. Taken as context and never as a trade, clustered buying is a conviction tell and clustered selling a caution.

Totals cover stored disclosures only; archive completeness is not established. Amounts use 30/90-day windows ending 2026-10-03.
Fresh principal purchases: principals net-buying who bought in the last 30 days · Principal buys: open-market only, plumbing excluded · Principal sells: open-market principal sales · Cluster buys: two or more distinct principal buyers · Pledge-risk names: a pledge created or invoked.
Directors, promoters and key managers must disclose their own dealing. We only treat open-market buying by those principals as meaningful; routine plumbing like inter-se transfers and ESOP allotments is classified out.
By company: 30 and 90-day windows ending on the latest filing, whatever the tape's window below, sorted by fresh buying. A revised filing replaces its original, so nothing is counted twice. Amounts are rupees, never share counts.

How we know this2 of 5 fields not recoverable
- Rule
- No selection rule - this surface filters nothing. It republishes the disclosures the exchange published, in filing order.lens_registry: insider, sast, shp
- Source
- NSE bulk/block feed; NSE (SEBI PIT Reg 7(2) disclosures); NSE (SAST Reg 29 + pledge Reg 31/32 listings); NSEredistribution: public-record · feed licence: public-archiveprovenance.PROVENANCE chain: bulk_block_deals · feed_manifest.FEEDS['insider_events'] · feed_manifest.FEEDS['sast_events'] · feed_manifest.FEEDS['deals']
- Knowable at
- disclosure_dt = exchange DISCLOSURE/broadcast date, never the transaction date; exchange broadcast/system timestamp, never the event date; same-evening publish (~19:30 IST); no free dated back-archive for bulk/blocka real (INGESTED) clock; this render resolved no per-row date, so the feed's written rule is given instead of onefeed_manifest.FEEDS['insider_events'] · feed_manifest.FEEDS['sast_events'] · feed_manifest.FEEDS['deals']
- Base rate

- Falsifier
- not recoverable from available datano settled test and no blocking failure model is on record for this surface - read it as unproven, not as working. What is on record is a handling fence, which constrains how the data may be used but states nothing that could turn out to be false: insider_events: taxonomy-fenced ('promoter bought = bullish' is BANNED; plumbing classes never mix with open-market conviction); sast_events: descriptive-only (stake + pledge FLOW context; content-hash idempotent); deals: descriptive-only…our failure-model record, the strategy reference, and the feed manifest
