The single most underused position in retail options trading is the bull call spread. New traders skip it because the upside is capped. Experienced traders use it because the risk-adjusted return is often higher than the long call it replaces.

Structure

Buy one ATM or slightly OTM call. Sell one further-OTM call on the same expiry. The trade is a net debit. Max risk is the debit paid. Max reward is the difference between strikes minus the debit.

Why the math is better than a long call

Long calls overpay for vega and theta. Selling a further-OTM call against your long call recovers some of that premium. You give up the unlimited upside above the short strike - but for most directional moves, your model price is below that strike anyway.

Example

Stock at $100. Buy the $102 call for $3.50, sell the $108 call for $1.50. Net debit: $2.00. Max profit: $4.00 (the $6 spread width minus $2 debit). Break-even at $104. Compared to buying just the $102 call, you cut your cost by 43% and your break-even by 18% - you give up the part of the upside above $108 that, statistically, the move was unlikely to reach anyway.

When to use it

Directional move expected but capped by recent resistance.
IV elevated and you want to neutralize vega exposure.
Earnings or catalyst inside the window and you do not want to lose to IV crush.

When not to use it

Stocks that can gap 20% on a binary event. There, you actually want the unlimited upside of the unhedged call. Spreads cap the lottery scenarios - that is the trade-off.
