Key characteristics

When to use a long straddle

Buy a straddle when you expect a large move but are unsure of the direction — for example around earnings, a court ruling, or a product launch. You buy a call and a put at the same at-the-money strike, profiting from a big swing either way.

The key question is whether the move will be larger than the combined premium plus any drop in implied volatility, because you have effectively paid for two options.

The IV crush trap

A straddle bought before earnings can lose even if the stock gaps, because implied volatility collapses afterwards and deflates both options — the infamous IV crush. The stock must move more than the market already priced in.

Maximum loss is the total premium, reached if the stock sits still; the two breakevens are the strike plus and minus the combined premium.

Worked example. Stock at $100 before earnings. You buy the $100 call for $3 and the $100 put for $3, total $6 ($600). Breakevens are $94 and $106. If the stock jumps to $112, the call is worth $12 and the put expires — a $600 profit; if it barely moves, you lose much of the $600 to IV crush.

Key takeaways

Frequently asked questions

Why did my straddle lose money when the stock moved?

Most likely IV crush — the move was smaller than the implied move, so the drop in volatility outweighed the price change.

Straddle or strangle?

A straddle uses the same at-the-money strike (costlier, needs a smaller move); a strangle uses OTM strikes (cheaper, needs a bigger move).

When is the best time to buy a straddle?

When you expect a big move and implied volatility is still relatively low, so you are not overpaying before the event.
