Long Call Calendar Strategy
Profit from time itself — near-term decay works for you while the far-term holds value.
What is the Long Call Calendar Options Strategy?
A Long Call Calendar Spread uses TWO different expiry dates — same strike, different months. You sell a near-term call (which decays fast) and buy a longer-term call at the same strike (which decays slowly).
As days pass, the near-term option you sold loses value faster than the one you bought. This difference in decay speed IS your profit. The stock needs to stay near the strike for this to work best.
This is one of the few strategies that directly profits from the passage of time without needing the stock to move.
Why is it Called "Long Call Calendar"?
"Calendar" because the two options are on different dates on a calendar — different months, same strike. "Long" because you paid a net debit (the far-term call costs more than the near-term one). Also called a "time spread" or "horizontal spread."
How Does the Long Call Calendar Trade Work?
- 1 Step 1 — Pick a stock you think will stay near a specific price for the next few weeks.
- 2 Step 2 — Sell a call expiring in ~2 weeks at that price.
- 3 Step 3 — Buy a call at the SAME strike expiring in ~6 weeks.
- 4 Step 4 — Pay the net debit (far-term costs more than near-term).
- 5 Step 5 — As time passes, the near-term call decays faster. When it expires worthless, you still own the far-term call.
Types of Long Call Calendar Strategies
Long Call Calendar (Standard)
Sell near-term call, buy same-strike longer-dated call. Profit from differential time decay.
Diagonal Calendar
Same concept but the two strikes are different (diagonal). Adds a directional bias. More flexible, slightly more complex.
When to Use the Long Call Calendar Strategy?
- Before earnings — sell the pre-earnings weekly, hold the post-earnings monthly (IV expansion play)
- When a stock has been stuck in a tight range
- When IV is low — you want to own long-term options cheaply and fund them by selling short-term
- When you expect IV to increase in the far-term
Profit and Loss of the Long Call Calendar
Before looking at the chart, here is a plain-English summary of what you can make and what you can lose.
Depends on IV and time decay — peaks when the stock is at the strike as the near-term option expires.
The net debit paid. Never more.
Dynamic — depends on the remaining value of the long-dated option when the short-dated one expires.
Long Call Calendar Payoff Diagram
The chart below shows how profit/loss changes with the underlying price at expiry. Green zone = profit, red zone = loss.
Long Call Calendar Example Trade
| Action | Type | Strike | Premium |
|---|---|---|---|
| Sell | Call | ₹1,500 (14-day) | +₹28 |
| Buy | Call | ₹1,500 (45-day) | -₹48 |
INFY stayed at ₹1,505 for 2 weeks. The 14-day call expired worthless (you kept ₹28). Your 45-day call still has ₹35 of value. Net position worth ₹35 vs ₹20 cost. Profit: ₹15 = 75% return.
Pros & Cons of the Long Call Calendar
- Profits from time passing — unique among strategies
- Defined risk — only lose the debit
- Excellent pre-earnings IV play
- Works in quiet markets
- Needs the stock to stay near the strike — big moves hurt
- Complex to model — two different expiry dates
- Hard to visualize payoff at a single point in time
- Transaction fees on both legs
