Introduction
A debit spread is an options trading strategy where the trader incurs a net premium expense to establish the position. This strategy involves buying and selling options of the same class (either both calls or both puts) with different strike prices but the same expiration date. The goal is to profit from a favorable movement in the underlying asset’s price while limiting potential losses.
Historical Context
Debit spreads have been a staple in options trading since the advent of modern financial markets in the 1970s, particularly with the establishment of the Chicago Board Options Exchange (CBOE). Over the years, they have gained popularity among traders looking for strategies that offer a balance of risk and reward.
Types of Debit Spreads
Bull Call Spread
A Bull Call Spread involves buying a call option with a lower strike price and simultaneously selling a call option with a higher strike price.
- Example:
- Buy 1 XYZ 50 Call for $3.00
- Sell 1 XYZ 55 Call for $1.00
- Net Debit: $2.00
Bear Put Spread
A Bear Put Spread involves buying a put option with a higher strike price and selling a put option with a lower strike price.
- Example:
- Buy 1 XYZ 55 Put for $3.50
- Sell 1 XYZ 50 Put for $1.50
- Net Debit: $2.00
Key Events
- 1973: Introduction of listed options trading by CBOE.
- 1980s-1990s: Widespread adoption of option spreads as sophisticated trading strategies developed.

Detailed Explanations
Components of a Debit Spread
- Bought Option: An option purchased by the trader, which incurs an initial cost.
- Sold Option: An option written by the trader, generating premium income to offset the cost of the bought option.
- Net Debit: The overall cost of the strategy, which is the difference between the premiums paid and received.
Mathematical Formulas/Models
The profitability of a debit spread can be summarized by the following formulas:
- Max Profit: \((Higher\ Strike\ Price\ -\ Lower\ Strike\ Price) -\ Net\ Debit\ Paid\)
- Max Loss: \(\text{Net Debit Paid}\)
- Break-even Point for Bull Call Spread: \((Bought\ Call\ Strike\ Price\ +\ Net\ Debit\ Paid)\)
- Break-even Point for Bear Put Spread: \((Bought\ Put\ Strike\ Price\ -\ Net\ Debit\ Paid)\)
