What you receive as a subscriber
The two desks. What every call contains. When it reaches you. Why there is no track record on this page.
Updated 6 September 2026 · Potoos Research Services
In short. There is no track record on this page, and the reason is below. Every plan includes both desks: positional NSE cash equity, and buy-side index option calls. Every call gives you an entry, targets, a stop-loss and the reasoning behind it. It reaches you the day before the market opens, not during it. The calls come from one named analyst. He is Vinoth Kumar S, SEBI registration INH000027380.
The two desks
Every plan includes both. Act on the one that suits how much of the trading day you really have, or on both. They are different jobs. Neither one is a lighter version of the other.
Index options
Buy-side index option calls. The exit level is decided before you enter. This suits someone who can act around the market open.
Equity
NSE equity. You hold for the longer term. You need no derivatives, and no watching the screen all day; just check that your orders are in place.
What every call contains
The same structure every time, on both desks. We never send a bare instruction to buy something.
- Entry
- A range, not a single number, so you are not chasing a price that has already moved.
- Targets
- Staged, so you can decide how much to take off and when. One option lot cannot be split, so a staged exit on options needs more than one lot.
- Stop-loss
- Set before entry, never after. It is the level at which the idea is wrong.
- Reasoning
- Why this, why now. You should be able to disagree with it, which is only possible if it is written down.
A stop-loss is a trigger, not a guarantee. In a gap or a fast market, your actual fill can be worse than the level shown, and a stop-loss limit order may not fill at all. No analyst can change that. What we control is the level itself. It is decided in advance and told to you. It is not improvised after the trade has moved.
When it reaches you
Calls are published in the app the day before the market opens. They do not come during the session. You read them when you have time. You place your orders and get on with your day. An intraday option trade still needs your attention while it is open. Nobody has to sit watching a phone for a message that may or may not arrive.
Where the calls arrive
Calls arrive in the Potoos app. On Android, it is the Potoos Research app on Google Play. Or use web.potoosresearch.in in any browser, with nothing to install.
Why there is no track record on this page
This website publishes no return, win-rate or accuracy figures. SEBI lets a registered Research Analyst show past performance in public only after PaRRVA, its verification agency, has verified it, and only in the format SEBI sets. Unverified returns, win rates and accuracy figures are not allowed in public material. That rule applies to us and to every other registered analyst. It is worth knowing when you compare one analyst against another.
You can check the registration itself before any of this matters. Here is how to do that on SEBI's own register.
Why do stock advisory services never show their losing calls?
Two very different reasons produce the same silence. Telling them apart is most of what a buyer needs to know.
The first reason is curation. A service that markets itself on screenshots controls what you see. The losing calls quietly disappear. The highlight reel is shown to you as the history. Nothing forces such a service to show you anything. That is exactly why what it shows you proves nothing.
The second reason is the law. A SEBI-registered Research Analyst may show past performance in public only after PaRRVA, SEBI's verification agency, has verified it. Unverified figures, winners or losers, are not allowed in public material. So on many public pages, the compliant and the curated look the same. Neither one shows losing calls. The difference sits one layer down. It is whether a full record exists somewhere the author cannot rewrite.
A record that leaves out its losses is not a record. So the question to put to any service is not "show me your winners". It is "where do your losses live, and who can edit them?"
Common questions
Do I have to trade F&O?
No. Every plan includes both desks, and you can act on only the equity calls. The positional equity desk never needs a derivative, or a day spent watching the screen. SEBI published a study of individual traders in equity derivatives on 20 August 2026. It found 87.7% of them ended the year in the red. So this is a decision worth making with care.
Can I see the record before subscribing?
Not on this page. SEBI lets an analyst share past performance publicly only after PaRRVA, its verification agency, has verified it, and only in the format SEBI sets. Before you pay anything, you can check the registration itself, the fee cap that applies, and the grievance route. All of that is on public record.
Is there anything to install?
Not for the web version. The Potoos app runs in any browser at web.potoosresearch.in, with nothing to install. On Android, you can also install the Potoos Research app from Google Play. You sign up and complete KYC, which SEBI requires for every paying client. The signup also asks a few risk questions, which is our own practice. Then the calls appear in your account.
What happens when a call goes against me?
It will happen. Anyone who tells you otherwise is selling something. The stop-loss is set before you enter. So the exit is decided in advance, not in the moment. The position size is meant to be one you can hold.
Why do stock advisory services never show their losing calls?
There are two reasons. One is curating: they show you a highlight reel with the losers removed. The other is regulation: a registered analyst may show past performance in public only after PaRRVA, SEBI's verification agency, has verified it, and only in SEBI's format. The two can look identical on a public page. So the real test sits behind it. Does a complete record exist that the author cannot edit?
