An earnings calendar lists the scheduled dates and times (before open or after close) when public companies report quarterly financial results. Earnings announcements are the single largest source of overnight implied volatility expansion and contraction in equity options.

Key takeawayCheck the earnings calendar before selling any premium. Selling a 30-day strangle on a stock that reports in 10 days means you are implicitly taking a binary event bet that may not be reflected in your risk management.
💡 Why It Matters
The earnings calendar is the premium seller's most important planning tool. Earnings drive 60-70% of annual IV expansion/contraction cycles in single stocks, and accidentally holding short premium through an unplanned earnings date is one of the most common retail mistakes.
⚙ How It Works
Public companies report quarterly (some monthly), typically within 4-6 weeks of quarter-end. The calendar shows confirmed and estimated dates, pre-market or after-hours timing, and consensus estimates. Implied volatility begins expanding 2-3 weeks before the report and collapses (IV crush) immediately after.
📋 Example
You sell a 45-DTE strangle on AMZN on March 1. AMZN reports earnings on April 25. Your strangle expires May 2. The strangle's IV includes the earnings event, meaning a disproportionate share of the premium you collected is earnings premium. If you close before earnings, you capture the theta but miss the IV crush. If you hold through, you take the binary risk.
⚠ Common Mistakes
Traders sell premium 30-45 DTE without checking if earnings fall within that window. The elevated IV makes the premium look attractive, but it includes a binary event risk that theta cannot offset. Always separate your earnings premium strategy from your non-earnings premium selling.
