The Information Is Public — Most People Just Don't Read It
Every listed company in India is required to disclose a stream of information — results, board decisions, who owns the shares, and when insiders trade. It is all free and public. Yet most retail investors never open a single filing, relying instead on tips and headlines.
Learning to read filings — especially insider and shareholding disclosures — gives you the same primary information the professionals use.
This article shows where filings live, the key disclosures to read, how to interpret promoter and insider activity legally, and the red flags to watch for.
Where Filings Live
Listed-company disclosures are filed with the exchanges and are free to view:
BSE — Corporate Announcements / Corporate Filings, per company
NSE — Corporate Information, per company
Aggregators (Trendlyne, Screener.in, Tickertape) compile and summarise them for convenience
These are filed under SEBI's LODR (Listing Obligations and Disclosure Requirements) regulations. For anything important, read the original document — summaries can lose nuance.
For the broader filing framework (annual report, BRSR, AGM, LODR Reg. 30 material events), see our companion article, SEBI Corporate Filings Decoded.
Reading Insider Trading Disclosures
Under SEBI's Prohibition of Insider Trading (PIT) regulations, "insiders" — promoters, directors, designated employees, and connected persons — must disclose trades in their company's shares above set thresholds. These are public.
Legal vs illegal insider trading:
Disclosed dealing by insiders within the rules is legal and public. Trading on unpublished price-sensitive information is illegal insider trading — a serious offence. Reading the legal disclosures simply tells you when the people who know the business best are buying or selling their own stock.
A single trade proves little — insiders deal for many reasons (liquidity, diversification, ESOP exercise, pledge adjustments). A sustained pattern of meaningful insider buying alongside strong fundamentals is more telling; persistent selling or rising pledges deserves a closer look.
Reading the Shareholding Pattern
Filed (usually quarterly), it shows ownership split across promoters, FPIs, domestic institutions (MFs, insurers), and the public. Track it over several quarters for the trend:
The shareholding trend is a useful read on smart-money conviction — a complement to, not a replacement for, fundamental analysis.
Bulk & Block Deals
Bulk deal: a client's total buy/sell in a stock exceeds 0.5% of listed shares in a day — disclosed after market hours
Block deal: a large single negotiated trade above a high value threshold, in a special window
These reveal when big players — funds, HNIs, promoters — take or exit sizeable positions. Informative context, but the reason behind any single deal is not always knowable.
Red Flags in Filings
Rising pledged promoter shares
Repeated auditor or independent-director resignations
Frequent or unexplained related-party transactions
Sudden, unexplained promoter selling
Delayed results or qualified audit opinions
Large gaps between reported profits and actual cash flows
Clusters matter:
Many of India's biggest blow-ups had these warning signs in their filings well before they collapsed. No single red flag is conclusive — but a cluster of them is a strong signal to stay away. For the full list, see our 12 red flags when evaluating stocks.
Go Deeper — The Complete Valuation & Picking Framework
Reading filings is one stage of picking stocks well. See how it fits with valuation, screening, and portfolio tracking in the complete guide.
Listed-company disclosures are filed with the stock exchanges and are free to view on the BSE (under Corporate Announcements / Corporate Filings) and NSE (under Corporate Information) websites for each company. These cover quarterly results, board-meeting outcomes, shareholding patterns, insider-trading disclosures, and material events filed under SEBI's LODR regulations. Aggregators like Trendlyne, Screener.in, and Tickertape compile and summarise these for convenience. For anything important, read the original document on the exchange site rather than relying only on a summary, as nuance can be lost.
Under SEBI's Prohibition of Insider Trading (PIT) regulations, 'insiders' — promoters, directors, designated employees, and other connected persons — must disclose their trades in the company's shares above certain thresholds. These disclosures are filed with the exchanges and are public. Legal insider trading (disclosed dealing by insiders within the rules) is different from illegal insider trading (trading on unpublished price-sensitive information, which is an offence). Reading these disclosures tells you when the people who know the business best are buying or selling their own stock — useful context, though never a standalone buy/sell signal.
Not on its own. Promoter or insider buying can be a positive signal — insiders know the business intimately, and buying with their own money suggests confidence. But it is only one data point. Insiders buy and sell for many reasons unrelated to valuation (liquidity needs, diversification, ESOP exercises, pledged-share adjustments). A single purchase proves little; a sustained pattern of meaningful insider buying alongside good fundamentals is more telling. Equally, persistent insider or promoter selling, or rising share pledges, deserves a closer look. Treat insider activity as supporting evidence within your own analysis, not as a trigger.
Listed companies file a shareholding pattern (usually quarterly) showing how ownership is split among promoters, foreign portfolio investors (FPIs), domestic institutions (mutual funds, insurers), and the public. It matters because changes reveal who is accumulating or exiting. Rising promoter holding or growing institutional (FPI/MF) ownership is often viewed positively; falling promoter stake or, especially, rising promoter share pledges can be a warning. Tracking the shareholding pattern over several quarters shows the trend of smart-money conviction in the stock — a useful complement to fundamental analysis.
Both are large trades disclosed by the exchanges. A bulk deal is a trade where the total quantity bought or sold by a client in a stock exceeds 0.5% of the company's listed shares in a day; it is disclosed after market hours. A block deal is a large, single negotiated trade (above a high value threshold) executed in a special trading window. These disclosures reveal when big investors — funds, HNIs, promoters — take or exit sizeable positions. Like insider data, they are informative context about large-player activity, but the reasons behind any single deal are not always knowable, so interpret with care.
Several warrant caution: rising pledged promoter shares; repeated resignations of auditors or independent directors; frequent or unexplained related-party transactions; sudden, unexplained promoter selling; delays in filing results or qualified audit opinions; and large gaps between reported profits and actual cash flows. Many of India's biggest blow-ups had such warning signs disclosed in filings well before the collapse. No single red flag is conclusive, but a cluster of them is a strong signal to stay away.
