Why "just buy calls before earnings" usually loses even when you're right
Everything the market expects is already in the premium: implied volatility peaks at the last close before the report and collapses the moment the numbers are out. A call bought the night before needs the stock to move more than the implied move in the right direction just to break even — a smaller-than-priced move loses money on both calls and puts. Our IV crush guide walks through the mechanics; the expected-move calculator turns a straddle price into the break-even you'd need.

Frequently asked questions
Should I buy DAL before earnings?
That is a decision only you can make, and this page does not give advice. What the data says: options price a move of ±8.6% for the Oct 8, 2026 report, so a long call or put needs Delta Air Lines Inc to move more than that in the right direction to profit after IV crush.
Does DAL implied volatility go up before earnings?
Typically yes: implied volatility in the nearest expiration builds as the report approaches because the event's expected move is priced into that expiration, then collapses once results are out.
When does DAL IV peak before earnings?
At the last close before the report — the final session before the print carries the biggest step for most names, which is why an IV-rush trade is exited before that close and never held through the announcement.
What is DAL's implied move for the next earnings?
Options currently price about ±8.6% for Oct 8, 2026 (before market open); the 10-year average move is about ±6.0%.
