Implied vs Realized
Compare straddle-implied move to typical realized move. If implied > realized historically, sell premium (iron condor / calendar). If implied < realized, buy premium (long strangle).
IV Crush
Front-month IV typically drops 30-50% after the print regardless of direction. Premium sellers profit; premium buyers need a move larger than implied to overcome the crush.
Catalyst Risk
After-hours liquidity is thin. Spreads widen. Never use market orders into earnings. If your structure is naked, max loss can multiply 3-5× the max gain.
