Strategy: Debit Spreads

Buy a call and sell a higher-strike call, same expiration.

The short call reduces cost and theta, but caps profit.

QQQ at $500: buy $500 call ($10), sell $510 call ($5). Net debit $5 ($500).

Max profit = width − debit = $10 − $5 = $5 ($500). Max loss = $500. Breakeven = $505.
