VIGIL Signals File: 13 Flags on NSE Filings, and a Prompt to Run Your Portfolio Through Them
Published: October 30, 2026
Want different flags - as per your angle? Just have your AI agent download the full VIGIL database and build your own.
NSE puts out a steady stream of company filings, on insider trades, promoter pledges, takeovers and credit ratings. Most of it is routine. A promoter selling a large block in one go, or a lender taking a promoter's pledged shares, comes in the same stream as thousands of ordinary trades.
I have picked out 13 situations that need a closer look and turned them into flags, one column each in the VIGIL signals file. Most carry the date of the latest filing, so you or your AI can pick any time window.
These are based on the filings that I track and my own analysis and judgment. Not all of them are red flags, and something can still slip through.
All 13 are listed below for quick reference, and in the detailed docs.
For your AI
"Go to tigzig.com, download the VIGIL signals file, and tell me which of my stocks have any of the red flags"

The 13 flags
All 13 flags for quick reference. Full descriptions are in the data dictionary.
Distress
- Rating red flag: downgrade, default, negative outlook, rating watch or speculative grade
- In insolvency: NSE lists the company under the insolvency process
- Under severe exchange action: insolvency, a lender restructuring agreement, unpaid listing fees or the strictest surveillance stage
Insider and promoter trades
- Promoter sold down: a promoter cut their holding by 1 percentage point or more in one market sale
- Promoter sold 5% or more at once: in one takeover filing
- Promoter bought up: a promoter raised their holding by 1 percentage point or more in one market purchase, usually good news
- Outsider acquired 5% or more: in one takeover filing
- Insider traded derivatives: futures or options on the company's own stock
Pledges and encumbrance
- Promoter pledged shares: a new pledge
- Over 50% company pledged: more than half the company's shares pledged by promoters
- Most of promoter holding encumbered: more than 50% of what the promoters own is tied up
- Encumbered without a pledge: a new non-pledge encumbrance, such as a non-disposal undertaking
- Pledged shares invoked: a lender took a promoter's pledged shares
