Strike configurations
Sell one call and buy three higher-strike calls instead of the standard 1x2 ratio.
Key difference: Even more upside leverage and a larger net credit or smaller debit, but a wider loss zone between strikes.
Best for: Traders with strong conviction in an explosive move who want maximum convexity.
Choose strikes so the extra long call premium is fully financed by the short call, producing a net credit.
Key difference: No upfront cost and profit even if the stock stays flat, but the loss zone between strikes is where the trade hurts most.
Best for: Traders who want to be paid to hold a bullish tail-risk hedge.
Common questions
The loss zone sits between the short strike and the point where the extra long calls' gains offset the short call's loss — a moderate rally that stalls in that band is actually the worst outcome, worse than the stock staying flat or falling.
Both — it needs a large move to profit meaningfully, similar to a long straddle, but it's structured with upside skew and can be built for a net credit, unlike a straddle.
Because the loss zone is bounded but real, many traders set a hard stop-loss or close the position early if the stock stagnates near the danger zone rather than holding to expiration.
A 1x2 keeps the loss zone narrower and the position closer to delta-neutral at entry; higher ratios like 1x3 increase leverage and potential payout but widen the range where the trade can lose money.
