Debit and credit spreads are mirror images. A bull call debit spread and a bull put credit spread on the same underlying with the same strikes have nearly identical payoff profiles. The key difference is how IV affects profitability.
Bullish on AAPL at $185: Two Approaches
Debit spread: Buy the $185 call, sell the $190 call for $2.20 debit. Max profit $2.80, max loss $2.20. You need AAPL above $187.20 to profit. Credit spread: Sell the $180 put, buy the $175 put for $1.80 credit. Max profit $1.80, max loss $3.20. You profit as long as AAPL stays above $178.20. The credit spread has a higher win rate; the debit spread has better reward-to-risk.
The IV Rule of Thumb
Check IV rank on ApexVol before choosing. IV rank below 30%? Debit spreads are cheaper and offer better value. IV rank above 50%? Credit spreads let you sell expensive premium and benefit from potential IV contraction.
