Basis, Rollover & Settlement

The Two Prices

Meera had just finished dinner when she opened her trading app, the way she did most evenings — half habit, half hope.

She'd bought a futures position in a company she liked, a mid-sized paints business whose ads she'd been seeing on the local train for months. Her phone showed two numbers, side by side. The spot price — what the stock was actually trading at right now — read ₹842. Right next to it, the futures price for her contract read ₹851.

She stared at it for a second. Same stock. Same evening. Two different prices.

Her first thought was that the app had glitched. She refreshed it. The numbers didn't move. She opened a second app just to check — same gap, more or less. Nothing was broken.

She sat back on the bed, phone still in hand, feeling that small itch of not understanding something she thought she should. "If it's the same company," she muttered to her ceiling fan, "shouldn't it be the same price?"

She didn't chase an answer that night. She just noted it — a ₹9 gap — and let it sit at the back of her mind, the way you notice a crack in a wall you're not ready to fix yet.

Three weeks later, she opened the app again. Expiry for her contract was five days away — the date had been sitting quietly on her calendar since the day she'd bought the position. Out of habit, she checked the two prices again.

Spot: ₹864. Futures: ₹866.

The gap had shrunk. From nine rupees to two.

Meera didn't know exactly why. But she noticed it. And for the first time, instead of feeling confused, she felt something closer to curious — like watching two people who'd been walking a few steps apart slowly falling into step with each other as they neared the same door.

The door, in this case, had a date on it. And in five days, that door was closing — whether she'd decided what to do about it or not.

• Explain why a futures price and its spot price are rarely identical, and why this gap (basis) shrinks as expiry approaches.
• Describe rollover as a deliberate choice to close an expiring futures position and open a similar one in a later cycle, rather than an automatic or purely technical process.
• Explain settlement as a known, pre-scheduled event at expiry rather than a sudden or risky occurrence.
• Apply the idea of 'deciding on purpose vs. letting the deadline decide' to a real time-bound commitment in one's own life.

Why does this matter? Because right now, when you look at a futures price and the spot price of the same stock and see they don't match, it feels like something is broken. And when an expiry date is coming, it can feel like a wall you're about to hit. Neither of those feelings is accurate — and once you see why, both the price gap and the deadline stop being scary.

Here's what's actually true. The gap you saw Meera notice — futures at ₹851, spot at ₹842 — has a name: basis. Basis is simply the difference between the futures price (what people agree to pay for the stock at a future date) and the spot price (what the stock trades at right now). This gap is completely normal. Every futures contract has one. It exists because the futures price reflects some uncertainty about the time still left before the contract ends — and the more time left, the more room there is for that gap to exist.

As the contract's expiry — the fixed date the contract ends — gets closer, that uncertainty shrinks, because there's less time left for anything to change. So the gap shrinks too. This is called convergence: the futures price and spot price move closer together the nearer you get to expiry, until at expiry itself, they meet. That's exactly what Meera saw — ₹9 apart three weeks out, only ₹2 apart with five days to go.

Now, because every futures contract has that fixed expiry date, it also quietly sets up a decision. You can't just leave a futures position sitting there forever — the contract insists on an ending. So as expiry nears, a trader lands at what we can call the decision point, with exactly two paths, no silent third option:

That shift matters more than the mechanics themselves.

1. Rollover — deliberately close the expiring contract and open a similar one in the next expiry cycle, so the position (and your view on the stock) continues on purpose.
2. Settlement — let the contract end as scheduled, usually through a cash payment based on the final price difference.

Rollover isn't some insider trick reserved for professionals. It's the same thing as renewing a lease on purpose before it lapses, instead of waking up on the last day wondering what happens now.

And settlement isn't a cliff-edge either. The date is fixed and known from the moment you open the position — it's sitting on the calendar the whole time, exactly like it sat on Meera's calendar for three weeks before she even looked at it again.

Both basis and settlement, then, are just information and a schedule — not danger.

That shift matters more than the mechanics themselves.

The real skill this unit is building isn't "predicting basis" or "timing rollover perfectly" — those aren't things anyone can do with certainty, and that's not what's being taught here. The skill is noticing the deadline early and deciding on purpose what you'll do about it, instead of waiting for the calendar to force your hand at the last moment.

Five days before expiry, Meera opens her app again on the sofa, the same way she has every evening. The gap she'd noted weeks ago — ₹9 between futures and spot — has now narrowed to just ₹2. She isn't surprised anymore. She half-expected it, remembering how the two prices had been "falling into step" the closer expiry got.

She scrolls up to check the date. It's right there, unchanged since the day she opened the position: five days away. Nothing sudden about it.

Instead of waiting until the last trading day to figure out what to do, Meera decides that evening. She still likes the paints company's prospects — nothing about her view has changed — so she chooses to continue her position rather than let it end. She closes her current futures contract at ₹866, and in the same sitting, opens an equivalent one in next month's expiry at ₹870.

She writes both numbers in her notebook: exit at ₹866, entry at ₹870. Not because she has to, but because it turns a decision she made once, calmly, into something she can look back on — instead of a scramble she'd have made in a panic on the last day, with the market rushing toward expiry around her.

That's rollover. Not a trick. Just a choice, made a few days early instead of a few minutes late.

Point: Rollover is a proactive, calendared decision made ahead of the deadline (closing one contract and opening a similar one further out), not a last-minute scramble - and the shrinking basis near expiry is expected, not alarming.

• Assuming that if the futures price and spot price for the same stock don't match, something is wrong with the app, the market, or the trade. — Learners expect a contract that 'tracks' an asset to mirror its price exactly, since they haven't yet learned that time left until expiry naturally creates a gap. Fix: Remember that a gap (basis) between futures and spot is expected and normal in every contract — it typically narrows on its own as expiry approaches and disappears exactly at settlement.
• Treating rollover as a complicated, expert-only maneuver that beginners shouldn't attempt to understand. — The word 'rollover' sounds technical, and closing one contract while opening another feels unfamiliar the first time you hear about it. Fix: See rollover as nothing more than a deliberate choice to continue a position past its deadline — the same as renewing any time-bound commitment on purpose, just applied to a futures contract.
• Fearing settlement as a sudden, risky event that catches a trader off guard. — Beginners haven't lived through an expiry yet, so an unfamiliar ending feels unpredictable and threatening, like it could happen without warning. Fix: Check the calendar: every contract's settlement date is fixed and known from day one, so it can be planned for well ahead of time — it is scheduled, never a surprise.

• Basis — the gap between futures price and spot price — is normal and expected, not a sign that something is wrong.
• As expiry approaches, basis naturally shrinks and the two prices converge, meeting exactly at expiry.
• Every futures contract forces a decision near expiry: roll over on purpose, or let it settle as planned — there's no silent third option.
• Rollover is simply a deliberate choice to continue a position, not a technical trick reserved for experts.
• Settlement is a known, calendared event you can plan for in advance — never a sudden cliff-edge.

Q1. What is 'basis' in a futures contract?

• The difference between the futures price and the spot price of the same underlying
• The total profit a trader makes on a futures position
• The fee charged by a broker to open a futures contract
• The number of days left until expiry Answer: The difference between the futures price and the spot price of the same underlying — Basis is simply the gap between the futures price and the spot price of the same stock or asset. It's a normal, expected feature of every futures contract, not a sign of error.

Q2. True or False: A futures price and the spot price of the same stock should always be exactly equal, and any difference means something is wrong. Answer: False — A gap between futures and spot price (basis) is normal and expected in every futures contract. It usually narrows as expiry approaches and disappears at settlement — it doesn't mean anything is broken.

Q3. Why does the basis (gap between futures and spot price) typically shrink as expiry approaches?

• Because there is less time left for uncertainty to matter before the contract ends
• Because brokers manually reduce the gap close to expiry
• Because trading volumes always fall sharply near expiry
• Because the spot price becomes fixed once expiry is announced Answer: Because there is less time left for uncertainty to matter before the contract ends — As the expiry date nears, there's less time remaining for uncertainty to affect the futures price, so it moves closer to the spot price. This is called convergence, and at expiry the two prices meet.

Q4. Rollover means immediately exiting a futures position for good, with no new contract opened. Answer: False — Rollover means closing the expiring contract and deliberately opening a similar one in a later expiry cycle, so the position continues on purpose — it isn't simply exiting for good.

Q5. Rohan holds a futures position that expires in one week. He still believes in the stock's long-term prospects and wants his position to continue without a gap. What should he do before expiry?

• Decide in advance to close the expiring contract and open an equivalent one in the next expiry cycle (roll over)
• Wait until the very last trading day and see what happens automatically
• Assume the position will continue on its own without any action needed
• Sell the underlying stock in the spot market instead Answer: Decide in advance to close the expiring contract and open an equivalent one in the next expiry cycle (roll over) — Since every futures contract has a fixed expiry, Rohan needs to actively roll over his position — closing the current contract and opening a new one in the next cycle — if he wants to keep his exposure going on purpose, rather than leaving it to the last moment.

Q6. A trader panics as a futures contract's expiry approaches, saying: "Settlement is coming and I have no idea what's about to happen to my position." Should settlement feel like an unpredictable surprise? Reveal: Weak: yes, settlement can be scary and unpredictable. Strong: the settlement date is fixed and known from the day the contract opens — it can be planned for well in advance; feeling surprised means the trader skipped preparing for a date that was never hidden.
