Stocks and index option calls, always with entry, target and stop-loss.
You get the call the day before the market opens, so you are never waiting at the screen for a message. From a SEBI-registered analyst, twenty years in the markets.
Two desks. Pick your pace.
Same analyst, same discipline, two very different speeds. Every call arrives complete either way.
Index option calls
Buy-side option calls with the stop-loss set before you enter, so you know the level the trade is closed at from the moment you take it.
Derivatives carry real risk, and we treat them that way. A stop-loss on every call. A position size you can hold. And never a promise about how it turns out.
Positional equity calls
For people who cannot watch the market all day. Positions held for weeks to months, with the reasoning to hold through the noise.
This desk is for salaried people, business owners and home-makers looking after the family savings. You choose your desk when you subscribe. Nothing about intraday or F&O is ever forced on anyone.
Every call complete. Everything verifiable.
Three things every subscriber gets. The last one you can check yourself, before paying a rupee.
The call reaches you a day early
Calls go out the day before the market opens, never during it. You read it calmly, place your order, and get on with your day. No sitting at the screen waiting for a message.
Nothing hidden, ever
Every call stays in your app, dated and timestamped. Winners and losers on the same screen.
Verifiable on SEBI
Registration you can check on the regulator's own register in two minutes.
The analyst who signs every call
One name on the registration, same name on the research. No anonymous tip desk behind a logo.
SEBI RA · INH000027380
Vinoth Kumar S
Twenty years in the markets, in equities and derivatives. Every call that reaches your screen carries his name, his reasoning and his registration number. At Potoos, being answerable is something we do, not something we say.
"How much can I make?" is the one question we will not answer with a number. Anyone who does is lying to you.
We show you the real numbers instead. What a sensible range looks like. What it costs to try. And why a promised return is the surest sign of a service to walk away from.
Three plans. Prices on the page.
Suggested minimum capital: ₹50,000.

Published prices, not negotiated ones
Every plan and price is on this page. Nobody will quote you a different number on a call, and there is no premium package waiting behind a phone conversation.
There is a legal ceiling on fees
No registered analyst may charge a family more than ₹1,51,000 in a year. Anyone quoting you a bigger package is not operating inside the rules.

How to check any analyst, including us
Most people who lose money to a tips service were never told what to look for. Four checks, and they work on anyone.
Find them on SEBI's register
Every genuine research analyst has a registration number you can look up on sebi.gov.in. A screenshot is not proof, the register is. If the name or city does not match their website, stop there.
Treat a promised return as the warning
No registered analyst is allowed to promise you a return, an accuracy percentage or a sure-shot call. So anyone who does is either unregistered or breaking the rules. The promise itself is the red flag, not the proof.
Look up their complaint record
Every registered analyst has to publish complaint data every month, and link a grievance route. Ours is in the footer of this page. If you cannot find one on a service you are considering, ask them why.
Never share an OTP or your broker login
No analyst ever needs access to your trading account, your password or a one-time password. Nobody legitimate will ask, and we never will.
Before you pay anyone, including us
How do I verify you are genuinely SEBI registered?
Don't take our word for it. Go to SEBI's public register and search INH000027380. Check that the name, Vinoth Kumar S, and the city, Chennai, match this website. Do this for any analyst you ever consider.
How much capital do I need?
We suggest at least ₹50,000. Below that, subscription costs eat too large a share of any realistic outcome. That is also why we publish this number instead of taking anyone's money.
Do I need to trade F&O or intraday?
No. The two desks are separate, and you pick yours when you subscribe. The positional equity desk never needs a screen or a derivative. And before you look at any F&O service anywhere, know SEBI's own number. 87.7% of individual F&O traders lost money in FY26. Our F&O desk is for people who understand that number and want defined risk, a stop-loss on every call, and a maximum loss they know before they enter.
What exactly do I receive?
Calls in the Potoos app with entry, targets, stop-loss and the reasoning, sent the day before the market opens so you are never waiting on a live message. Holding runs from intraday on the F&O desk to weeks and months on the equity desk. You always know why, not just what.
What if I follow a call and lose money?
That will happen, and anyone who tells you otherwise is selling something. The market goes against good reasoning all the time. What we control is the discipline. A stop-loss set before you enter. A position size you can actually hold. And the reasoning written down, so you can judge it yourself instead of taking it on trust. What we do not control, and will never pretend to, is how any single call turns out.
What is a free demo call worth?
Nothing, and that is the honest answer. Anyone can show you a handful of winners, and it tells you nothing about what comes next. That is why subscribers see our whole record in the app instead, losses included, never edited.
Why is there no track record on this page?
Because SEBI's advertisement code does not permit analysts to display past performance publicly, and that rule protects you. Anyone flashing returns on a public page is breaking it. Our policy inside the app: every call kept, dated, losses on the same screen as wins, nothing edited after the fact. How our record-keeping works →
Who sends stock and option calls with entry, target and stop-loss before market opens?
We do, and how it works matters more than the name. Potoos Research Services is a SEBI-registered Research Analyst, Vinoth Kumar S, INH000027380, Chennai. Every call goes into the app the day before the market opens. Each one carries an entry range, staged targets, a stop-loss set before entry, and the reasoning in writing, on both the equity and the F&O desk. Whoever you look at for this, run them through the register check above before you pay. That includes us.
Which is the best stock advisory service in Chennai?
Nobody can honestly answer that with a name, ours included. SEBI's advertisement code stops every registered analyst from publishing performance, so no "number one" claim in this business can be backed up in public. What you can do is compare services on facts you can check. A SEBI registration you verify yourself on the register. Prices published on the page, inside the legal fee cap of ₹1,51,000 per family per year. A complete record kept, with the losses left in. And a complaint route that works. Our own checkable facts: SEBI Research Analyst INH000027380, research desk in Chennai, every price on this page, record kept in the app. Hold anyone you compare us with to the same list.
