Insider trading, and the tip in your group chat
The answer
Insider trading is buying or selling on important information that has not been made public. It is illegal in every serious market — and the law reaches the person who receives the tip, not only the person who leaked it. If a tip is genuinely valuable, either it is false, or acting on it puts you inside the offence.
Why this costs you money
Two costs, and the smaller one is the legal risk.
The first cost is that almost every tip is worthless.
Ask the question that dissolves most of them: if this information is true and valuable, why is it being given to me, for free, by someone who could use it themselves?
There are only 3 honest answers. It is not true. It is already public and already in the price. Or somebody wants you to buy so they can sell to you.
By the time information travels from a person inside a company, through a friend, through a WhatsApp group, to you — it has been traded on several times. You are not receiving information. You are receiving the exhaust of information, and you are buying from the people who received it earlier.
The second cost is that you can be penalised as the receiver. Many people assume the offence belongs to the employee who leaked it. In India, a person who trades while in possession of unpublished price sensitive information can face action regardless of where they got it. "Somebody told me" is not a defence. It is a description of the offence.
How it works
Two conditions have to be met, and both words matter.
Material — a reasonable investor would consider it important in deciding whether to buy or sell. Results before publication, a merger under negotiation, a large contract won or lost, a regulatory action about to land, an auditor about to resign.
Non-public — it has not been disclosed to the exchange or otherwise made generally available.
Miss either condition and it is not insider trading. Gossip about a manager's mood is non-public but not material. A published quarterly result is material but not non-public.
Who is an insider? Far more people than employees. Directors, auditors, lawyers, bankers, printers, the company's PR agency, a spouse, a driver — and anybody they tell. In India, connected persons are presumed to have access, and the chain extends to whoever receives the information.
How companies are supposed to prevent it. Listed companies must close their trading window before results. They must keep a structured digital record of who was given sensitive information and when. Designated employees must pre-clear their trades. These are real controls, and their existence is why the cases that do occur usually involve somebody deliberately going around them.
What it tells you, and what it does not
The existence of insider trading law tells you that markets depend on the belief that the game is not fixed. Nobody provides capital to a market where the people inside are known to be trading against the people outside.
It does not tell you that no leaking happens. It does. Price and volume frequently move before an announcement, and regulators frequently investigate after seeing it.
And it does not tell you that all informational advantage is illegal. This is the part most articles get wrong, and it is where the useful lesson is.
The decision rule
Apply 2 questions to every tip, before anything else.
- If this were true and valuable, why is it free and why is it coming to
me?
- Was the person who originally knew this allowed to tell anyone?
If the answer to the second is no, then acting on it is not a shortcut. It is a position in an investigation, and you are the most junior and least protected person in the chain.
And then the constructive half: read the legal version instead. Insiders are required to disclose their own trades in their own company, publicly, within days. That information is free, lawful, and almost nobody reads it.
Try this now
You are going to read what real insiders actually did, using the disclosure the law forces them to make.
In India:
- Go to the NSE website and search a company you hold.
- Open Corporate Announcements, then the filter for Insider Trading — it may be listed as disclosures under the SEBI PIT Regulations.
- Read the last 12 months. You will see named individuals, quantities, dates and whether it was a purchase, a sale, or a transfer.
In the United States:
- Go to the SEC's EDGAR search and enter the company.
- Filter for Form 4. These are filed within 2 business days of an insider trading their own company's shares.
What you should see. Mostly routine activity — shares acquired under employee plans, small sales for tax or personal reasons. That in itself is the lesson: real insider activity is boring, documented and public, and it looks nothing like a dramatic tip.
Occasionally you will find something worth a second look — several unrelated executives buying with their own money in the same month. That is the legal signal, and the next article is about how much weight it deserves.
Three real cases
1. Rajat Gupta, convicted 2012 (United States) — the chain reaches the top A Goldman Sachs board member passed confidential board information to a hedge fund manager, including news of Berkshire Hathaway's investment during the 2008 crisis. He was convicted of securities fraud and conspiracy and served a prison sentence. Gupta did not trade himself and, by most accounts, was not paid directly. The offence was passing the information.
2. Martha Stewart, convicted 2004 (United States) — the cover-up Stewart sold shares in a biotech company shortly before bad regulatory news became public. She was never criminally charged with insider trading at all. She was convicted of conspiracy, obstructing an agency proceeding and making false statements — for what she said to investigators afterwards. A civil SEC insider-trading case was settled separately in 2006. The detail is worth carrying: in these cases the explanation given to investigators frequently becomes the more serious charge.
3. The WhatsApp leaks (India, 2017 onward) — the group chat is the case SEBI investigated the circulation of unpublished quarterly figures for several large listed companies in private messaging groups, days before the official announcements. The numbers circulating were close to the eventual results. SEBI passed orders against individuals involved, though several were later set aside on appeal, the tribunal finding that SEBI had not established the circulated figures as unpublished price sensitive information. The mechanism, not the outcome, is the point here. This is the case that makes the subject concrete for an Indian retail investor: the mechanism was not a boardroom in Manhattan. It was a WhatsApp group.
The question that resolves it
A novice hears a tip and asks: is it true?
An expert asks: who else already knows this, and what have they already done?
Information has a life cycle. By the time it reaches somebody with no professional connection to the company, it has usually been acted upon several times. The question is never whether it is true. It is where in the queue you are standing.
What would make this wrong
If every informational advantage were illegal, then fundamental research would be pointless and no analyst could add value. That is plainly not the case, and the law does not say it is.
The distinction that matters is called the mosaic theory. An analyst may lawfully gather many individual pieces of information — none of them material on their own, all of them legitimately obtained — and assemble them into a conclusion that is valuable. Counting trucks leaving a factory, reading customs data, talking to a supplier's competitor, noticing hiring patterns. The conclusion may be worth a great deal. Each input was public or immaterial.
This is the honest, legal, difficult route to an edge, and it is the one worth building. It is slow, it requires work, and it cannot be handed to you in a message.
The limits also run the other way. The line between diligent research and inside information is genuinely blurred at the edges, and professionals employ compliance departments precisely because it is hard. If you find yourself constructing a careful argument for why a specific piece of information is probably fine to use, that difficulty is itself the answer.
In India
The SEBI (Prohibition of Insider Trading) Regulations, 2015 govern this. The central term is UPSI — unpublished price sensitive information.
Several features are worth knowing:
- The regulations are framed around possession of UPSI while trading, which is a broader test than proving you used it. There are defined defences, but the starting position is not favourable to a trader who was in possession.
- Trading windows close ahead of results for designated persons, and companies must maintain a structured digital database recording who received UPSI.
- Insider disclosures must be filed for trades above a threshold, and they are published on the exchange websites.
- SEBI operates an informant mechanism with monetary rewards for whistleblowers in insider trading cases.
For an ordinary investor, one practical point overrides all of it: the person who forwards you a tip in a group has no compliance department, no legal advice and no incentive to protect you.
In the United States
There is no single statute named "insider trading". It is prosecuted mainly under the general anti-fraud provisions, and the law has been built up through court decisions.
The American framework rests on breach of a duty. Broadly, liability attaches where confidential information was disclosed in breach of a duty and the recipient knew or should have known. Cases have turned on whether the person who leaked received a personal benefit — a question that has been litigated extensively and has shifted over time.
Practical features:
- Regulation FD requires that when a company discloses material information to analysts or institutions, it must disclose it publicly at the same time. This is why earnings calls are open to everyone.
- Rule 10b5-1 plans let insiders schedule trades in advance, so a sale that was set up months earlier is not evidence of anything.
- Penalties are criminal as well as civil, and prison sentences are routine.
Where they differ, and what that tells you
The 2 systems ask different first questions.
The United States asks: was there a breach of duty, and did the recipient know? India asks: were you in possession of unpublished price sensitive information when you traded?
What that tells you is how much room the "I just heard it somewhere" story has. In the United States, the duty requirement gives a genuinely unconnected recipient more ground to stand on. In India, possession while trading is closer to the heart of the test, and the ground is narrower.
For an Indian retail investor, the practical translation is blunt: the defence you have seen in American films and television — I overheard it, I owed nobody anything — is a worse fit for the law you actually live under. The imported intuition is not just useless here. It points the wrong way.
Carry this
- If a tip is valuable, ask why it is free and why it came to you.
- The receiver is liable too. "Somebody told me" is a description of the offence, not a defence.
- The legal version — insider disclosures and Form 4 — is free and unread.
- The lawful edge is the mosaic: many small public pieces, assembled with work.
