From Expiry Trading to Stock Options — Chetan’s Trading Journey

ELI5 / TLDR

A self-taught options trader from a Marwadi family talks through how he made money, then how he kept making it after the rules changed. He started by selling options on expiry days — collect the premium, go home flat, repeat. When India’s regulator throttled that game (fewer expiry days, fatter margins), he didn’t quit. He carried the same underlying idea — get paid for taking on other people’s risk — into single-stock options and positional index trades. The other half of the conversation is blunter than the strategy talk: trading is a rich man’s game, small accounts are a trap, and being a “full-time trader” is mostly an Instagram fantasy.

The Full Story

The core never changed, the wrapper did

Around 2023, selling options on expiry day was close to free money. The market threw off enough volatility that the premium you collected dwarfed the risk you carried, and you carried it for only a few hours.

“That was a very good time for expiries. You had so much volatility.”

Then the regulator stepped in. Expiry days got cut, margins went up, the friction piled on. The easy version of the trade went away. Rather than mourn it, Chetan asked what the trade actually was underneath. The answer: harvesting risk premium. Getting paid to insure other people against moves.

“Our core will remain the same — we will harvest risk premia, but we’ll move to a different land.”

That land is single-stock options, now roughly half his book. The rest splits across positional index trades (Bank Nifty, Sensex) and a smaller slice of expiry and commodities (crude and gold). Same engine, different vehicles.

Why Sensex over Nifty

A small, specific nugget for anyone who thinks the two big indices are interchangeable. Nifty and Sensex correlate at about 0.99 — they move together. But Chetan finds Sensex pays a slightly richer variance premium. The cycles are offset (Sensex runs Thursday-to-Thursday, Nifty Tuesday-to-Tuesday), and liquidity concentrates in Nifty, which leaves the Sensex premium a touch fatter for a seller. Bank Nifty pays more again because its higher beta means richer premiums. The whole craft is finding where the insurance is overpriced.

Accepting the thing that used to scare him

Expiry trading had one comfort: you were insulated. Whatever Trump said overnight, whatever happened in China, none of it touched you, because you were flat by the close. Stock options are positional. Suddenly he had to hold exposure through the night and eat the gaps.

“Initially it was a pain, but then you have to do it, because you have to diversify.”

His fix was mechanical, not motivational. He sized the position down until the overnight swing stopped raising his blood pressure, got used to that level of noise, then sized back up. The discomfort wasn’t argued away; it was dosed.

There’s a reason he bothered. The smoothness of an equity curve — the Sharpe, the Calmar ratio — has to come from somewhere. The core strategy gives you returns, not smoothness. Spreading across instruments and holding periods is where the smoothness hides.

“What you don’t get intraday, you try to get in the positions.”

Directional, but with the strikes as a fence

Here’s the irony he points at himself: he started as a non-directional, delta-neutral seller, and his stock-options book is now mostly directional. Why give up neutrality? Because non-directional selling is a first-principles trade everyone can run — sell the 20-delta, hedge the delta, done. It’s democratised, which means crowded, which means thin.

So he takes a directional view — but expresses it through options, not futures, so the strike is a fence he can’t fall past.

“I don’t have the idea of how much the market can go in my direction. But I have an idea of what the market should not do.”

He sells below a level he believes holds (often anchored to something like a 100-day moving average as a mean-reversion reference). If he’s right on direction, good. If the market goes sideways, theta still pays him. The strike caps the damage if he’s wrong.

Diversification doing its job

When a senior figure at HDFC resigned and the stock took a hit, his position was one of thirty-odd names. The portfolio damage was negligible.

“Because you have such a big diversification across stocks, it works out.”

His whole posture is that on any given day, something works — a stock trade, expiry, crude. He’s not firefighting losers the way many post-COVID traders do, rolling and shifting a busted position to avoid booking the loss. He cuts fast when price action turns against him and lets the diversification absorb the rest.

Is expiry trading dead?

He won’t say dead. The money is still there because the risk is still there, and you get paid for risk. What’s gone is the quality of the returns — the smooth equity curve. You might still clear 20-25%, but the old 40% with low drawdown is harder now. Developed-market sellers, he notes, are happy with 2%; Indian traders got spoiled.

The part that isn’t about strategy

The back half is a lecture, gently delivered, on who should be doing this at all. His own path was backwards from the textbook. Most people trade, then invest, then buy real estate. He did real estate first — funded by a stock-market windfall.

The windfall: 2009, working at an IT company, watching Satyam crash 80% to about 6.5 rupees after its fraud blew up. He figured a company that size wouldn’t simply vanish, put in around 35,000 rupees, and walked out with 1.5 lakh — the down payment on his first property. Then he didn’t touch equity for years.

“Beginner’s luck works for beginners. I knew it would not work for me.”

His money came from the internet first — an e-commerce business (online collars, one of the early Indian sellers on the platform) with a beautiful structure he explains plainly: negative working capital. The customer’s advance funded the order before he paid the supplier. Cash came in before it went out.

On the current mania, he’s flat: he’s watched Class 11 students talk about trading because of an Instagram reel and a Lamborghini, and he thinks an entire generation is being set up for disappointment.

“A new trader, what kind of capital are you going to bring? You’re going to get into stuff which is less probable. You might not be able to hold your position.”

His number, pushed for one, is one crore. Not because you’ll trade it all — margin might use 20 lakh — but because large money makes you accountable. With 5 lakh, the back of your mind says “if it goes, I’ll refill it.” With a crore, you stop reaching for leverage on your own.

“Trading is a rich man’s game, whether you like it or not.”

And full-time trading, in his view, is a trap dressed as freedom. The market closes at 3:30. Then what? He reached financial freedom in his mid-twenties and found the beach gets boring after a month. He keeps a pipeline — real estate, hospitality, a consulting gig he keeps for the joy of it. He still trades by hand, not because his algos don’t exist (they do, built in-house) but because discretion lets him overlay fresh context onto price, and because it feels like a video game and a meditation. The biggest gains come from the events an algo can’t read in time.

Key Takeaways

• The durable thing in his trading isn’t a strategy, it’s a principle: get paid to harvest risk premium. When the regulator killed easy expiry selling, he ported the principle to stock options rather than chasing a new edge.
• Equity-curve smoothness and raw returns are separate problems. The core strategy supplies returns; diversification across instruments and holding periods supplies smoothness.
• Sensex tends to pay a slightly richer variance premium than Nifty despite ~0.99 correlation — offset expiry cycles, liquidity concentrated in Nifty. Bank Nifty pays more again on higher beta.
• Express a directional view through options, not futures: the strike caps your loss and theta pays you while you wait. You don’t need to know how far the market goes your way, only what it shouldn’t do.
• Size a new, scarier exposure down until the volatility stops bothering you emotionally, then size back up. Habituation, not willpower.
• Cut fast, don’t firefight. Rolling and shifting a busted position to avoid booking a loss is the default failure mode he avoids.
• Capital is the real edge. His floor is ~1 crore — large money makes you accountable and removes the temptation to over-leverage. Small accounts burn out before compounding can begin.
• Full-time trading is not a destination. Keep a pipeline of other projects; financial freedom with nothing to do is its own problem.
• Negative working capital: customer advances fund your purchases before you pay suppliers — cash in before cash out.

Claude’s Take

This is a good interview, not a great one, dragged up a notch by how unguarded the subject is. He’s not selling a course. He says the quiet part — trading is for the already-rich, your favourite Instagram trader is a recruiting poster, the easy years are over — which is rare on a broker’s own YouTube channel.

The strategy content is real but thin on numbers. “Harvest risk premium, express directional views with capped risk, diversify for smoothness” is genuinely how a sensible options seller thinks, but he never quite shows the working — what his actual drawdowns are, how the 4% he claims to lose to manual execution was estimated, what “20-25%” is measured against. It’s texture, not a blueprint, and you should treat it as one trader’s lived intuition rather than transferable method.

The BS filter mostly comes back clean. The one place to raise an eyebrow is the discretion-beats-algo claim — he admits he’s never run his strategies live through the algo, so his confidence that human context-reading adds edge is unfalsified by his own data. That’s a comfortable belief for someone who enjoys trading by hand. Worth noting, not damning.

Seven out of ten. Honest, well-textured, occasionally sharp on the sociology of retail trading. Loses points for being long on philosophy and short on anything you could verify or replicate.
