What Is a Calendar Spread in Options Trading?
A calendar spread, also called a "time spread," involves buying and selling options with identical strike prices but different expiration dates. Traders profit from the accelerated time decay of short-term options relative to longer-dated ones. For example:
- Call Calendar Spread: Sell a 1-month call at Rs. 1,000 strike, buy a 3-month call at the same strike.
- Put Calendar Spread: Sell a near-term put, buy a distant-term put (e.g., on Nifty 50 index options).
This strategy thrives in stable markets where the underlying asset’s price hovers NEAR the strike price. Historical data from TradingView shows calendar spreads outperform single-leg strategies in low-volatility environments (e.g., VIX below 20).
How Does a Calendar Spread Work? Step-by-Step
Here’s the mechanics of a typical calendar spread trade:
- Sell Short-Term Option: Collect premium from an option expiring in 30 days.
- Buy Long-Term Option: Pay premium for an option expiring in 90+ days.
- Net Debit/Credit: The cost is the difference between premiums (e.g., Rs. 40 paid – Rs. 20 received = Rs. 20 net debit).
As the short option decays faster, traders can buy it back cheaply while holding the long option for potential gains. A 2023 BTCC analysis noted that 65% of profitable calendar spreads closed positions before the short option’s expiration.
Real-World Example: Calendar Spread on Reliance Industries
Consider Reliance stock trading at Rs. 2,500:
| Action | Option | Strike | Expiry | Premium |
|---|---|---|---|---|
| Sell | Call | Rs. 2,500 | 1 month | Rs. 80 |
| Buy | Call | Rs. 2,500 | 3 months | Rs. 150 |
If Reliance stays near Rs. 2,500 at the short call’s expiry, the trader buys it back for Rs. 20 (profit: Rs. 60) and retains the long call for future moves.
Pros and Cons of Calendar Spreads
- Time Decay Profits: Short options lose value faster (theta advantage).
- Lower Capital: Requires less margin than naked options.
- Flexibility: Adjust strikes/expiries for bullish, bearish, or neutral outlooks.
- Volatility Shocks: Sudden price moves can erode profits (monitor IV rank via CoinGlass).
- Complexity: Requires active management—not a "set and forget" strategy.
Advanced Calendar Spread Strategies
Combine different strikes and expiries (e.g., sell Rs. 2,500 call expiring in 1 month, buy Rs. 2,600 call expiring in 6 months).
Use both calls and puts to hedge volatility (e.g., during earnings season).
The BTCC derivatives team recommends pairing calendar spreads with technical analysis (e.g., support/resistance levels) to time entries.
Long vs. Short Calendar Spreads: Key Differences
| Factor | Long Calendar Spread | Short Calendar Spread |
|---|---|---|
| Market View | Neutral/stable prices | Expect large price swings |
| Risk | Limited to net debit | Unlimited if wrong |
| Best For | Beginners | Advanced traders |
