Should I buy straddles before earnings?

It depends on IV. If IV is already high (pricing in a big move), the straddle may be expensive and hard to profit from even if the stock moves. Compare current IV to historical realized moves around earnings.

What's the difference between a straddle and a strangle?

Straddles use ATM options at the same strike; strangles use OTM options at different strikes. Strangles cost less but need larger moves to profit. Straddles cost more but start profiting with smaller moves.

How does IV crush affect straddles?

IV crush (falling volatility after an event) hurts straddle buyers. Even if the stock moves in your direction, falling IV can cause both options to lose value. This is why post-earnings straddles often disappoint.

Straddle Calculator

A straddle involves buying both a call and a put at the same strike price and expiration. It profits from large moves in either direction.

Long straddles are volatility plays—you're betting the stock will move significantly, but you're unsure which direction. They're commonly used before earnings announcements or other catalyst events.

The main risk is time decay (theta). If the stock doesn't move enough to offset the cost of both options, you lose money. Straddles require big moves to be profitable.

Frequently Asked Questions

The stock must move beyond your breakeven points (strike price plus or minus total premium). For example, if you pay $5 for a straddle at the $100 strike, the stock needs to go above $105 or below $95 to profit at expiration.
