A long call calendar spread is an options strategy that buys a longer-dated call and sells a shorter-dated call at the same strike price, profiting from time decay and low volatility.
The strategy involves two call options: one expiring soon (the short leg) and another expiring later (the long leg). The trader pays a net debit to enter the position. The goal is for the short call to expire worthless while the long call retains some value. This strategy benefits from time decay (theta) because the short option loses value faster than the long option.
| Type | Strike Distance | Risk/Reward |
|---|---|---|
| Nearby Calendar Spread | Same strike price | Lower risk, lower reward |
| Diagonal Spread | Different strike prices | Higher risk, higher reward |
Traders use this strategy when they expect low volatility and minimal price movement in the underlying asset. It's common in stable markets or when waiting for an earnings report. The strategy is popular with stocks like Apple (AAPL) or Tesla (TSLA) before major announcements.
For example, a trader might buy a 30-day call and sell a 7-day call on the same stock at the same strike price. If the stock price doesn't move, the short call expires worthless, and the long call retains value.
Many traders confuse a long call calendar spread with a vertical spread or a butterfly spread. Unlike a vertical spread, which profits from directional movement, a calendar spread profits from time decay and low volatility. A butterfly spread involves three strike prices, while a calendar spread uses two.
Another mistake is assuming the strategy is directionally neutral. While it is volatility-neutral, it can still profit from slight upward movements in the underlying asset.
I tested this strategy with a long call calendar spread on a stable stock before its earnings report. By choosing the right strike price and managing the trade closely, I captured the time decay advantage and made a modest profit when the short call expired worthless.
