- A straddle buyer needs the index to finish more than about 1.07% away from the strike by expiry just to break even, before costs and taxes.
- A straddle seller keeps the premium only if the index finishes between the two breakevens; beyond them losses grow, with no cap on the upside.
How it works
Upper breakeven = strike + total premium. Lower breakeven = strike - total premium. Premiums here are for the same strike, same expiry.
