What is Rollover? A Simple Guide for Indian Traders
Rollover is the process of carrying a derivative position from the expiring contract to the next expiry. The trader closes the current month and opens the same position in the next one. It lets traders keep exposure beyond a single expiry.
Derivatives expire, but your view might not. Rollover is how traders carry a position forward into the next contract instead of letting it lapse.
It is a routine move for positional traders and hedgers. Let us unpack it with a real example and the points that matter. You can roll positions on Stockk.
Key Takeaways
- Rollover carries a position to the next expiry.
- You close the current contract and reopen in the next.
- It keeps exposure alive beyond one expiry.
- It avoids forced settlement, including delivery.
- Rollover percentage is a sentiment cue.
Why do traders roll over positions?
Derivatives expire, so a trader who wants to keep exposure beyond expiry must move to the next contract. Rollover avoids forced settlement, including physical delivery for stock derivatives. It is common among positional traders and hedgers who need continuous exposure across months.
Take the case where you hold one lot of Reliance futures, lot size 500, bought in the June contract. Expiry is near and you want to keep the position. June futures trade at ₹2,900 and July futures at ₹2,918. You sell June at ₹2,900 and buy July at ₹2,918, so the roll costs ₹18 per share, or ₹9,000 for the lot, before brokerage and statutory charges on both legs. That ₹18 gap is the price of carrying the position for another month.
What does rollover data reveal?
The rollover percentage measures how much open interest moved from the expiring month to the next, and it is watched as a sentiment cue. High rollover suggests traders are carrying conviction forward, while low rollover suggests positions are being closed.
The cost of rolling over
| Element | What it means |
|---|---|
| Price difference | Gap between the two contracts |
| Transaction cost | Brokerage and charges on both legs |
| Rollover cost | The total of the above |
When traders usually roll over
Rollover activity tends to rise in the final days before expiry, as traders decide whether to carry positions forward. Timing the roll well can reduce cost, which is why active traders watch the rollover window closely.
