Rollover is the process of closing a position in an expiring derivatives contract and simultaneously opening the same (or similar) position in a later-dated contract. Traders roll positions to maintain market exposure without dealing with physical delivery (futures) or exercise (options). Rollover timing and costs are important considerations for longer-term derivative positions.
- Close expiring position, open later-dated position
- Maintains exposure without delivery/exercise
- Rollover cost depends on term structure
How Rollover Works
Rolling extends your position:
Rollover Example (Futures):
Current Position: Long Feb Nifty Futures at 22,000
Feb Expiry: 5 days away
March Futures: Trading at 22,050
Rollover:
1. Sell Feb futures at 22,000 (close)
2. Buy March futures at 22,050 (open)
3. Rollover cost: ₹50 per unit
If lot size = 50:
Total rollover cost = ₹50 × 50 = ₹2,500
You maintain long exposure but paid ₹2,500
to roll from Feb to March.
Quick Reference: Rollover
| Scenario | Action | Cost |
|---|---|---|
| Contango (far > near) | Roll costs money | Negative carry |
| Backwardation (near > far) | Roll earns money | Positive carry |
| Flat curve | Minimal cost | Near zero |
Example: Options Rollover
Rolling a Covered Call:
| Step | Action | Price |
|---|---|---|
| Current | Short $105 March Call | $2.50 |
| Close | Buy back March Call | $0.50 |
| Open | Sell April $105 Call | $2.75 |
| Net Credit | Collected | $2.25 |
Rolled for a credit—extended time and collected premium.
Rollover means closing an expiring position and opening the same position in a later contract. It maintains your market exposure without delivery or exercise. Roll costs depend on term structure—contango costs money, backwardation pays you. Time your rolls to avoid illiquidity.
When to Roll
Options
- 1-2 weeks before expiration
- When theta decay accelerates
- Before liquidity dries up
Futures
- 2-5 days before expiration
- When volume shifts to next month
- Before rollover week congestion
Rollover Strategies
Roll Forward (Same Strike)
Keep same strike, move to next month. Simple extension.
Roll Up/Down
Change strike while rolling. Adjust based on new market view.
Roll and Adjust
Combine roll with position sizing changes.
Calendar Roll
Specifically rolling from near-month to far-month.
Rollover Costs
Contango
Far month more expensive. You pay to roll. Common in VIX futures.
Backwardation
Near month more expensive. You get paid to roll. Common during shortages.
Calculating Roll Cost
Roll Cost = Far Month Price - Near Month Price
Common Mistakes
-
Rolling too late – Liquidity drops, spreads widen near expiry.
-
Ignoring roll costs – Contango can significantly erode returns over time.
-
Not considering strike adjustment – Sometimes rolling to different strike makes sense.
-
Forgetting transaction costs – Two trades (close + open) means double commissions.
