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.
Buying the MU straddle at the last close and holding through: 7 of 15 paid
The backtester replays a long ATM straddle entered at the last close before each of Micron Technology's last 15 reports and marked at the reaction-day close — real contract prices, not theory. Long vol won 7 of 15; short vol is the mirror image.

Frequently asked questions
Should I buy MU 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 ±12.0% for the Sep 30, 2026 report, so a long call or put needs Micron Technology to move more than that in the right direction to profit after IV crush.
Does MU 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 MU 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 MU's implied move for the next earnings?
Options currently price about ±12.0% for Sep 30, 2026 (after market close); the 10-year average move is about ±8.8%.
