Quick context: This article is about the process — how to keep a watchlist honest over time. The six forensic checks it relies on are explained in the beginner's red-flags checklist. If you have not read that one, start there; this piece assumes you know what CFO, a qualified opinion and a pledge are.
Most watchlists I am shown have the same history. A name was added after a friend mentioned it, another after a results-day headline, three more after a YouTube video on "multibaggers". Six months later there are forty names and nobody can say why eleven of them are there.
That is not a watchlist. It is a scrapbook.
A watchlist earns its place in your process only if it does one job: keep bad companies out, and push companies that turn bad back out again, without you having to remember to do it. The red-flags checklist tells you what to look for in one company on one afternoon. This article is about running the same checks as a standing habit across twenty or thirty names, quarter after quarter.
# Think of it as three gates, not one list
A useful watchlist has three layers, and most people only build the first.
- Entry filter. What has to be true before a company is allowed on the list at all.
- Knock-out rules. A short set of binary conditions that remove a company automatically, whatever you think of the business.
- Review cadence. A fixed schedule for re-checking, so the knock-out rules actually get applied.
The notes column — why each name is there — ties the three together. We will come to it.
The discipline that makes this work is simple to state and hard to keep: the rules are written down before you look at a specific company. Rules invented after you have fallen for a stock always turn out to have an exception for that stock.
# Gate 1 — the entry filter
The entry filter is not a quality test. It is a data test. Its job is to make sure you have enough history to run the forensic checks at all.
Reasonable entry conditions, which you should adjust to your own style:
- At least three full annual reports available. Every forensic comparison in the checklist is a trend, and a trend needs three points.
- A business you can describe in two sentences. If you cannot say how the company earns its money, you cannot tell whether a jump in receivables is normal for it.
- The right framework for the sector. Banks, NBFCs and insurers need asset-quality checks instead of the cash-conversion test. The sector-specific frameworks article covers the substitutions.
- The first pass of the six-check list done once, fully. Not skimmed. The first time you run it on a company takes the longest, and it is the baseline every later quarter is compared with.
Notice what is not on this list: price, recent returns, target prices, and "everyone is talking about it". Those may be why you noticed the company. They are not reasons for it to be on a research list.
# Gate 2 — five knock-out rules
Knock-out rules are different from the checklist. The checklist gives you a yes, a no or a needs-a-look for each item, and asks you to read the pattern. A knock-out rule is deliberately cruder: if it trips, the company leaves the list — unless the company's own filings give the kind of stated, checkable reason listed in the last column below.
The value is that it removes your own judgement at exactly the moment your judgement is least reliable — when you like the company.
| Knock-out rule | Where to find it | Trips when (set your own threshold) | The honest exception |
|---|---|---|---|
| Promoter pledge | Quarterly shareholding pattern on BSE/NSE | Pledged share of promoter holding is high, or has risen for two quarters in a row | Pledge created for a disclosed, time-bound purpose and released on schedule |
| Auditor event | Auditor's report in the annual report; exchange announcements | Qualified, adverse or disclaimer of opinion; or an auditor resigns mid-term | Normal rotation at the end of a term under the Companies Act |
| Profit not turning into cash | Cash flow statement and P&L, three to five years | Cumulative CFO falls below the percentage of cumulative PAT you have set, with no explanation in the report | A clearly disclosed working-capital build for a large, identifiable order |
| Related-party money leaving | Related-party transactions note | Loans, advances or guarantees to promoter-linked entities grow year after year and are not repaid | Routine items — director remuneration, a market-rate lease |
| Frequent equity dilution | Share capital note; exchange announcements of allotments | Share count keeps rising through preferential issues, warrants or QIPs while per-share earnings lag | A one-time raise for a stated project, with the project visible in later capex |
Two of these deserve a little more explanation, because they are where people most often talk themselves out of the rule.
# The cash rule, with numbers
Take a company with this three-year record (₹ crore):
| Year | PAT | CFO |
|---|---|---|
| Year 1 | 120 | 95 |
| Year 2 | 140 | 60 |
| Year 3 | 165 | 70 |
| Total | 425 | 225 |
Cumulative CFO is 52.9% of cumulative PAT. Profit grew every year; the cash did not follow. Whatever threshold you choose, a figure like this should trip it — and the job then is to find, in the annual report, a stated and checkable reason. If there is one, write it in the notes column and keep the company. If there is not, it leaves. The full method for reading this is in the cash flow forensic guide.
# The dilution rule, with numbers
Dilution is the red flag beginners miss most, because the headline numbers look fine.
Suppose a company's PAT grows from ₹100 crore to ₹140 crore over three years — 40% growth. Over the same period its share count rises from 10 crore to 11.5 crore through a mix of preferential allotments and warrant conversions. That is 15% more shares, or about 4.77% a year.
Your slice of the profit — earnings per share — grew only 21.7%, not 40%.
A single, explained raise is ordinary corporate finance. A company that returns to the market every year or two, especially through preferential allotments to a small group, is paying for its growth partly with your ownership. The share capital note and the exchange announcements show every allotment.
# The auditor rule, carefully
This is the one where getting the facts wrong causes false alarms. A change of auditor at the end of a term is mandatory rotation and means nothing. What matters is a resignation mid-term, and here SEBI's framework helps you: under SEBI's October 2019 circular on resignation of statutory auditors, a resigning auditor of a listed company has to give detailed reasons, which are disclosed to the stock exchanges along with the audit committee's views. Read that disclosure — it is usually more candid than anything else the company publishes that year. The auditor's report guide covers qualified opinions and Key Audit Matters.
For pledges, the promoter pledge analysis explains the two separate disclosures and how to read them.
# The notes column — the part everyone skips
Every name on the list should carry four short lines. Not a report. Four lines.
| Field | What to write | Example |
|---|---|---|
| Date added | The date the first full check was done | 12 Jan 2026 |
| Why it is here | The one-sentence thesis | Market leader in a niche; cash conversion above 90% for five years |
| What would prove me wrong | The observable event that breaks the thesis | Cash conversion below my threshold two years running; loss of top customer |
| Open questions | Items marked needs-a-look | Contingent liability for a tax dispute; check next annual report |
The third line matters most. When you write down in advance what would prove you wrong, you have a removal trigger that is specific to this company, on top of the general knock-out rules. And six months later, when a result disappoints and you feel the urge to explain it away, the note is there in your own handwriting.
Keep price out of this column. A note that says "add at ₹450" turns a research list into a trading list, and the two need different skills.
# Gate 3 — the review cadence
Knock-out rules only work if something makes you look. Tie the reviews to the dates companies are obliged to publish, not to your mood.
# Every quarter (after results)
- Revenue, operating profit and PAT against the same quarter last year.
- Shareholding pattern — promoter holding and the pledged/encumbered column.
- Exchange announcements since the last review — auditor changes or resignations, CFO or independent director exits, preferential allotments, warrant conversions, fund-raising approvals.
- Debt and receivables, where the company publishes a half-yearly balance sheet.
This is fifteen minutes per company if you keep it to these items. The quarter is too short a window for cash-conversion judgements; do not start rewriting your thesis on one quarter's working capital.
# Every year (after the annual report)
- The full six checks from the red-flags checklist, compared line by line with last year's notes.
- Related-party transactions note — the direction and size of loans, advances and guarantees.
- Contingent liabilities against net worth.
- Auditor's report and Key Audit Matters.
- MD&A language against last year's — the MD&A reading framework explains what to compare.
Most of the deterioration that hurts long-term holders appears in the notes to accounts, and the notes arrive once a year. The annual review is the one you cannot skip.
# What triggers removal
Write these down too. Removal should be as rule-bound as entry.
- Any knock-out rule trips without a stated, checkable explanation in the company's own filings. Out, no discussion.
- Your own "what would prove me wrong" line comes true. Out.
- The same needs-a-look item survives two annual reviews unanswered. A question the company will not answer in two years is an answer.
- You can no longer describe the business in two sentences — usually after an acquisition spree or a pivot. Out until you can.
What is not a removal trigger: the share price falling, the share price rising, or a broker downgrading it. None of those tells you anything about the quality of the financial statements, which is all this list is filtering for.
# A worked review, start to finish
Here is what one quarterly review looks like for a single name, in practice.
- Results out. Revenue up 14%, PAT up 18% year on year. Nothing unusual.
- Shareholding pattern: promoter pledge up from a low base for the second quarter running. Knock-out rule trips.
- Exchange announcements: a disclosure from the promoter group gives the reason — a loan against shares for a personal real-estate purchase, with a stated repayment date.
- Decision: the reason is stated and checkable. Stays on the list. Notes column updated: "Pledge rising two quarters; stated reason and repayment date noted — re-check in two quarters. If not released by then, remove."
That last sentence is the whole method. The rule tripped, you looked, you recorded what you found and set a date on which the explanation has to prove itself. You did not argue with the rule; you gave the company a deadline.
# Why this is worth the effort
A filtering habit will not tell you which company to buy. It is not meant to. What it does is keep your attention — which is the scarcest thing a retail investor has — on companies whose filings are not warning you. With thousands of listed companies to choose from, simply declining to spend time on the ones that trip a rule is a perfectly reasonable research strategy.
