Stock market tips: why an anonymous tip costs more than it says

Who is on the other side of a tip?

Someone who gains when you act, even when the sender means well.

A tip posted to a group of 5,000 people has reached everyone else on the list by the time it reaches you. Anyone who held the stock before the message went out is happy to sell into the buying it creates.

Sebi has described the pattern in its own words. It ran search and seizure operations at the premises of seven individuals and one company across Ahmedabad, Bhavnagar, Neemuch, Delhi and Mumbai. The regulator said they were running nine Telegram channels with more than 5 million subscribers. An earlier order, dated 12 January 2022, found that one Telegram channel's administrators enticed subscribers to act on recommendations "leading to significant price and volume impact in various scrips."

The channel makes the price move, and the price move is what the sender sells into.

What does a tip leave out?

Four things. Each one changes the outcome more than the stock name does.

Entry

"Buy X" does not say at what price. A stock that a channel pushes can be up 15 percent by the time you read the message. If the tip made sense at ₹100, it may not at ₹115, and the message never tells you which.

Exit

A tip has a start and almost never an end. Nothing in it says when to sell, at what loss, or after what news. A position with no exit rule is a position you will manage by mood, and mood is worst when the price is falling.

Size

This is the missing piece that hurts most. Take three percent of a ₹1 crore portfolio, which is ₹3 lakh. If the tip falls 40 percent, the loss is ₹1.2 lakh, which is 1.2 percent of the portfolio. That is survivable. Put ₹25 lakh into the same tip because the message sounded certain and the same 40 percent fall costs ₹10 lakh, which is 10 percent of the portfolio. The stock did the same thing in both cases. The size decided how bad it was. That is why a position is sized to survive a drawdown, a fall from a recent high, before it is bought.

The sender's own position

Does the sender own it? Did they buy before they posted? Are they selling while you buy? An anonymous tip answers none of these, and by definition you cannot ask.

What does the pump-and-dump shape look like?

The pattern has four steps, and it is the same on a Telegram channel as on a TV panel.

1. A thinly traded stock is bought quietly.
2. A tip names it, usually with a target and a sense of urgency.
3. Buyers arrive, the price rises, and the early holders sell to them.
4. The buying stops, the price falls, and the last buyers hold the loss.

Here is a hypothetical, with the arithmetic shown. A stock trades at ₹100. A tip pushes it to ₹120. You buy ₹5 lakh worth at ₹120, which is 4,166 shares, with ₹5 lakh divided by ₹120 and rounded down. The insiders have sold and the price returns to ₹90. Your holding is now worth 4,166 times ₹90, which is ₹3,74,940. The loss is ₹1,25,060, or 25 percent. The company may be sound. The loss came from buying at the top of a push.

This illustrates the mechanics and makes no forecast about any stock.

What do Sebi's own statements say?

They say the same thing from the other side. Sebi chairman Tuhin Kanta Pandey spoke at World Investor Week 2025. He said only 36 percent of investors have high or moderate knowledge of the securities market. That gap, he said, "exposes our investors to risks and makes them susceptible to fraud." He named unsolicited messages on messaging apps, dubious finfluencers and fake trading platforms. All of them, he said, promise what markets can never deliver: assured profits.

His advice came in four lines. Two apply here. Check every entity's registration status on the Sebi website. Treat any promise of assured profit as against the nature of markets.

Sebi has put this on a national footing. Project Jagrook is its nationwide investor awareness initiative. A circular dated 1 October 2026 directs stock brokers to show Sebi's awareness messages on their websites from 5 October to 31 October 2026. From 1 November 2026 the messages go on the landing page. Trading apps follow in phases.

Who is allowed to give advice, and how do you check?

Under the Sebi Investment Advisers Regulations and the Sebi Research Analysts Regulations, no person can act as an investment adviser or research analyst without a Sebi certificate of registration. Sebi said so in 2016, and it has said the details of registered advisers and research analysts are available on its website.

A check takes about two minutes:

• Ask the sender for their registered name and registration category.
• Search that name in the registered advisers and research analysts lists on sebi.gov.in.
• Confirm the name on the page matches the person or company that is messaging you, not a similar one.
• If the sender gives no name, the check ends there. That is the answer.

A registered name means someone who can be held to a standard stands behind the recommendation, right or wrong. An anonymous message has no one behind it.

What does a rule written before the buy replace?

It replaces the tip's missing four parts with your own. Before any buy, from any source, write down:

• the price at which you would enter, and the price above which you would not
• the loss at which you would leave, in rupees, sized to the fall you can sit through
• the size, as a percentage of the whole portfolio
• why this holding belongs in the portfolio at all

If you cannot fill all four lines, the tip has not told you enough to act on. If you can, the decision is your own, and the tip only supplied a name.

This is also why a portfolio built on a published method holds up better than one built on messages. A method tells you what it holds and why, before you act. A tip tells you after, or never. Two related reads ask the same question of a number. One explains why diversification removes one risk, not all. The other shows why bonus shares give you more shares, not more money.

The next tip you get

A tip costs more than it says because the cost sits in what it omits. The next time one arrives, ask for the four missing items before the stock name.

Frequently asked questions

Are stock market tips on WhatsApp or Telegram legal?

The regulations bar any person from acting as an investment adviser or research analyst without a Sebi certificate of registration. That, more than sharing an opinion, is the issue. Sebi has repeatedly cautioned the public against tips from unregistered persons.

How can I check whether a stock tipster is registered with Sebi?

Search the sender's registered name in the lists of registered investment advisers and research analysts on sebi.gov.in, and confirm the name matches the person messaging you. A sender who will not give a registered name has answered the question.

What is a pump-and-dump scheme?

It is a pattern where a thinly traded stock is bought quietly, promoted through tips, and sold into the buying the tips create. Late buyers hold the loss when the buying stops. In the worked example above, a buyer at ₹120 who sees ₹90 loses 25 percent.

What does a stock tip not tell me?

It does not tell you the entry price, the exit rule, the size to hold, or whether the sender owns the stock. Each of the four changes the outcome more than the stock's name does.

How much of a portfolio should one tip be?

A tip has no answer to this, so the answer has to be yours and written before the buy. As an illustration, three percent of a ₹1 crore portfolio is ₹3 lakh, and a 40 percent fall on that position costs 1.2 percent of the portfolio.
