Calendar Spreads

What It Is

A calendar spread involves buying a long‑dated option and selling a short‑dated option at the same strike price.

Why It Matters

It profits from time decay differences and stable price behavior.

How It Works

  • Buy a longer‑term option
  • Sell a shorter‑term option
  • Short option decays faster
  • Profit if price stays near the strike

Key Components

  • Time decay differential
  • Same strike, different expirations
  • Volatility impact
  • Neutral outlook

Example

Buying a 90‑day call and selling a 30‑day call at the same strike creates a call calendar spread.

Key Takeaways

  • Profits from time decay.
  • Works best in low‑movement environments.
  • Sensitive to volatility changes.
