How to Check Earnings Risk Before Selling Options

Why earnings wreck good-looking setups

In the days before a company reports, implied volatility climbs because the market knows a big, unpredictable move is coming. That makes premiums look unusually attractive to sellers. The catch: you're paid more because the risk is genuinely higher. After the report, two things happen at once:

• IV crush — implied volatility collapses once the uncertainty resolves. This helps short options.
• The gap — the stock can jump or drop 5–15%+ overnight. This can obliterate a short position regardless of the IV crush.

Sell a cash-secured put the day before earnings, collect a juicy premium, and a bad print can leave the stock well below your strike by morning. The premium never covered that.

"But the IV Rank is high!"

Right — and now you know why. Elevated IV Rank right before earnings is the textbook case of volatility that's high for a reason. High IV Rank is only an edge when it's not sitting on a known binary catalyst.

How to actually check it

1. Find the next earnings date and confirm whether it falls inside your option's expiry window.
2. Decide your stance: avoid (skip or close before the report), or deliberately trade the event with size and strikes that survive a gap.
3. Don't get surprised by cousins of earnings: ex-dividend dates and, for biotech/pharma, clinical-trial readouts and FDA decisions are the same kind of scheduled risk.

Two reasonable approaches

Avoid the event: most premium sellers don't hold short options through earnings. They sell in the calm stretches between reports, where high IV Rank reflects general nervousness rather than a scheduled bomb.

Trade the event on purpose: some sell strangles or iron condors into earnings to harvest the IV crush, but size small and pick strikes outside the expected move, accepting that some trades will lose. Both are valid. Selling into earnings by accident — because the premium looked good and you didn't check — is not.

How TickerRisk flags it

TickerRisk raises a ticker's risk score when earnings fall inside your selected horizon, and the events calendar shows earnings, ex-dividend and clinical-trial dates across the S&P 500 with each ticker's risk and IV Rank beside it. The point is simple: never sell premium into a catalyst you didn't know was there.
