Quick Summary
A SEBI registered research analyst can share a trade idea, a target, and a stop loss. What they cannot do is tell you the exact number of lots to buy. The moment an analyst says “buy 5 lots” or “trade 12 lots,” they have decided your position size, and position size depends on your capital and your risk, which makes it personalised advice an analyst is not licensed to give. A trade idea and a position size are not the same thing. This page explains where that line sits, shows how one trader lost ₹1.8 lakh following an exact lot-size call, and what you can do if it happened to you.
“Buy 5 lots now if you want maximum profit.”
You followed the lot size your analyst gave you, the trade went wrong, and now the loss is real.
You keep replaying the conversation, wondering if that instruction was even allowed.
That doubt is worth trusting. Most traders never think to ask whether an analyst can hand them an exact quantity; they assume it is part of the service.
It is not, and knowing where the line sits can turn “my bad trade” into “a violation I can act on.”
Can a Research Analyst Tell You Exactly How Many Lots to Trade?
Here is the straight answer:
No. A research analyst cannot recommend exact lot sizes.
Most traders do not learn this until a trade goes wrong. When an analyst sounds confident and experienced, it feels natural to assume every part of their call is legitimate.
But SEBI draws a hard line between research and personalised advice, and lot size sits on the wrong side of it.
To see why, it helps to separate what an analyst can say from what they cannot.
A research analyst is allowed to share the research side of a trade.
That means a trade or investment idea, the reasoning for being bullish or bearish, a target price, a stop-loss level, and a view on market trends.
What a research analyst cannot do is decide your position for you:
They cannot tell you exactly how many lots to buy or sell.
They cannot decide how much capital you should risk. They cannot set position sizes based on your finances. And they cannot cross into personalised investment advice.
The reason is simple, and it is the heart of this whole question.
A lot size is not just a trading number. It is a decision about your money. How many lots you take depends on your capital, your risk tolerance, and your financial situation.
A position that is comfortable for one trader can wipe out another.
That is why the moment an analyst says “buy 5 lots” or “go 10 lots,” they have stopped doing research and started making a personal financial decision for you, which needs a different licence.
This is the specific edge of a broader rule, and whether a research analyst can give personalized tips of any kind is covered in full on its own page.
How to Spot Lot-Size Pressure Before It Costs You?
An exact lot-size call rarely comes alone.
It usually sits inside a pattern of pressure, and each signal below is worth documenting, because each one strengthens a later complaint.
Watch for these: You are constantly pushed to increase your lot size for “higher returns.” The talk is all profit, with risk barely mentioned. You hear lines like “this trade cannot fail” or “go all in.”
You feel rushed to decide during market hours. Only the winning trades get talked about. You are made to feel that trading small is pointless, and your concerns about risk are brushed aside.
A genuine professional never makes you feel reckless for managing risk.
They treat protecting your capital as the first job, not an obstacle.
One of these pressure lines, “go all in,” deserves its own caution, because pushing you into a full position with no downside protection is a separate issue we cover in our guide: can a SEBI research analyst give trades without stop loss?
If any of these happened in your dealings with the analyst, write them down. Each is relevant to a formal complaint.
How “Just Follow My Lot Size” Cost One Trader ₹1.8 Lakh?
Sometimes the clearest way to see the rule is to watch it break.
Raj’s case is a plain example of an exact lot-size call doing real damage.
Raj (name changed) was not a seasoned trader. He had savings he wanted to grow, and he found an analyst who sounded like they knew exactly what they were doing.
So when the analyst said “buy 12 lots,” Raj did not question it. He assumed it was part of the service, that the analyst knew his situation and was sizing the trade accordingly.
The trade turned against him within days. By the time he exited, ₹1.8 lakh was gone.
What stayed with him was not only the loss. It was realising he never understood why 12 lots was the number in the first place.
That position was far larger than his risk could comfortably carry, and no one had ever asked what his risk actually was.
When Raj came to us, his first question was not about recovery.
It was: “Was he even allowed to tell me how many lots to buy?”
The answer, no, changed how we approached his entire case.
Because once an analyst names your position size, the loss is no longer just a bad trade. It flows from advice they were never licensed to give.
Lost Money on a Lot-Size Call? Here Is What to Do
If an exact lot-size instruction led to your loss, the sooner you act, the better, because the evidence: chats and screenshots, tends to disappear fast.
Start by saving everything that shows the specific quantity was recommended to you: the Telegram and WhatsApp messages, screenshots of the lot-size calls, any audio or session clips, your payment receipts, and any ads promising unrealistic profits.
In a case like this, a message that literally says “buy 12 lots” is your single strongest exhibit, because the specificity of the number is what proves it was position-sizing advice.
Then raise it in writing with the analyst, stating what was recommended, what you lost, and what you want.
Their reply, or their silence, becomes evidence too.
Since a registered analyst is involved, the door to a formal claim is open.
Start with a written grievance to the firm, and if that leads nowhere, a SCORES SEBI complaint is the next step, followed by a SMART ODR complaint and arbitration if it comes to that.

Conclusion
By the time most traders learn this rule, the loss has already happened. Learning it now still matters.
A research analyst can give you a trade idea, a target, and a stop loss. What they cannot do is decide your position size, because that depends on your money and your risk, not theirs.
A trade idea and a position size are two different things. One is research.
The other is a personal financial decision that an analyst is not licensed to make for you.
So if an analyst told you exactly how many lots to buy, that was not research. It was personalised advice without authorisation, and that gives you real grounds to act.
Frequently Asked Questions
No. How much capital to commit depends on your personal financial situation, which makes it advice, not research. Be cautious the moment a research service starts directing how much you should put in.
No. If the number was specific, "buy 5 lots," "trade 12 lots," it is personalised position-sizing advice, whatever it is called. The specificity of the number is what counts, not the label put on it.
No. Following a recommendation does not remove the analyst's responsibility for making it. If they were not authorised to give position sizes and did so anyway, the violation exists regardless, and your record of the specific call is what matters.
A research analyst can give market research, trade ideas, targets, and stop losses. An investment adviser is the one authorised to assess your finances and recommend a suitable position size. Naming your lot count is the adviser's job, not the analyst's.
