Four times a year, every company reports its earnings, and for options sellers those dates deserve real respect. Earnings is the one event you can see coming on the calendar that can undo a careful trade in a single move. Knowing how it works keeps you out of trouble.
Think of earnings like a storm marked on the forecast. You know the exact day it is coming. The air gets tense beforehand, then it breaks all at once, and the sky is suddenly calm again.
The build-up: rising volatility
In the days before a report, nobody knows what the numbers will say, so uncertainty climbs. That pushes implied volatility up, and every option on the stock puffs up in price. Premiums look unusually generous right before earnings, which tempts sellers, but that fat premium is the market pricing in a possible big move, not free money.
The break: gap and IV crush
When the report lands, two things happen fast. The stock can gap, jumping or dropping sharply as the market digests the news, sometimes far past where any strike sat. And the uncertainty vanishes, so implied volatility collapses, an effect called IV crush. Options deflate almost instantly. A buyer can even be right about direction and still lose, because the air rushed out of the premium.
How to handle it
For most beginner income sellers, the simplest rule is the safest: avoid holding a short option through earnings unless you fully intend to. Close or roll your position past the report, or wait until the storm has passed and volatility has settled to sell into calmer, more predictable conditions. If you do sell earnings volatility on purpose, size it small and know you are taking a real gamble on the move.
Always check the earnings calendar before you sell. An unexpectedly fat premium usually means a report is around the corner. Respect the date, and it becomes a risk you manage rather than one that ambushes you.
- Before earnings, implied volatility rises and premiums inflate; that fat premium is pricing in a possible big move.
- After the report, the stock can gap and volatility collapses in an IV crush, deflating options fast.
- Beginners should usually avoid holding short options through earnings: close, roll, or wait for calm.
