Options Whale · Strategy guide
Calendar spreads around earnings
Structure
A conventional long calendar buys a later-dated option and sells an earlier-dated option of the same type at the same strike. The position usually requires a debit. The two legs represent different time horizons, so their implied volatilities need not move together.
Earnings placement matters
A short expiration before earnings and a long expiration after earnings create a different exposure from a calendar in which both expirations include the report. Options Whale selects available contracts deterministically and preserves each expiration. It rejects an unsuitable structure instead of inventing a strike or expiration.
Risk cannot be summarized by one expiration line
At the short option's expiration, the long option still has time value. Its price depends on remaining time, the stock price, and later-expiration volatility. Maximum profit and breakevens therefore require assumptions. A model scenario should not be presented as a guaranteed payoff. Assignment of an American-style short option can also create stock exposure.
Evidence before selection
The research engine combines event-relative volatility, potential pre-event IV expansion, term structure, liquidity, and historical sample quality. Cheap IV alone does not justify a calendar. Rejected candidates retain their reason codes.
Read term structure and pre-earnings volatility, then inspect exact legs in earnings research. Compare the risk profile with an iron condor.
