What Is a Vertical Debit Spread?

A vertical debit spread involves buying one option and selling another option of the same type (call or put) with the same expiration date but different strike prices.

The goal is to reduce the cost of a long option by selling a higher-strike call or lower-strike put, creating a "spread." This strategy offers:

• Defined Risk: Your maximum loss is capped at the net debit paid.

• Higher Probability of Profit (POP): Compared to buying naked options, spreads increase your chances of success.

• Lower Cost: Access high-priced stocks like Apple or Google with less capital.

There are two main types: call debit spreads (bullish) and put debit spreads (bearish). Let’s explore each with examples.

Call Debit Spread: The Bullish Strategy

A call debit spread is used when you expect the stock price to rise. You buy an in-the-money (ITM) call and sell an out-of-the-money (OTM) call to offset the cost.

Example

• Stock Price: $100

• Buy: $95 call for $7.50 ($5 intrinsic + $2.50 extrinsic)

• Sell: $105 call for $2.50 credit

• Net Debit: $5.00 ($500 total, as each contract covers 100 shares)

• Spread Width: $10 ($105 - $95)

Outcomes

• Max Profit: $5.00 ($500) if the stock is above $105 at expiration. You buy at $95 and sell at $105, netting $10 per share minus the $5 debit.

• Max Loss: $5.00 ($500) if the stock falls below $95, as both calls expire worthless.

• Breakeven: $100 (stock price = $95 strike + $5 debit). If the stock stays at $100, the $95 call is worth $5, covering your cost.

• Probability of Profit (POP): ~50% for a 1:1 risk-reward (pay $5 to make $5). Paying more (e.g., $6) reduces max profit to $4 but increases POP.

• Return on Capital (ROC): Max profit ($5) ÷ debit ($5) = 100% if fully profitable.

Why Use It?

• Matches stock exposure (delta) for less cost than buying shares.

• Caps loss at the debit, unlike naked calls with higher breakeven.

• Ideal for straddling the stock price to break even at the current level.

Put Debit Spread: The Bearish Strategy

A put debit spread is used when you expect the stock price to fall. You buy an ITM put and sell an OTM put to reduce the cost.

Example

• Stock Price: $100

• Buy: $107 put for $8.20 ($7 intrinsic + $1.20 extrinsic)

• Sell: $95 put for $1.45 credit

• Net Debit: $6.75 ($675 total)

• Spread Width: $12 ($107 - $95)

Outcomes

• Max Profit: $5.25 ($525) if the stock is below $95 at expiration. You sell at $107 and buy at $95, netting $12 per share minus the $6.75 debit.

• Max Loss: $6.75 ($675) if the stock is above $107, as both puts expire worthless.

• Breakeven: $100.25 ($107 strike - $6.75 debit). If the stock stays at $100, the $107 put is worth $7, yielding a $0.25 profit ($25).

• Probability of Profit (POP): >50% due to the deeper ITM long put, which moves breakeven in your favor.

• Return on Capital (ROC): Max profit ($5.25) ÷ debit ($6.75) ≈ 78%, lower than the call spread due to higher cost and lower profit.

Why Use It?

• Profits from downside moves with less capital than shorting stock.

• Moving the long put deeper ITM increases POP and improves breakeven.

• Reduces extrinsic value exposure by hedging with the short put.

Why Trade Vertical Debit Spreads?

1. Higher Probability of Profit: Unlike naked options, which require significant price movement, debit spreads have breakevens closer to or better than the stock price, boosting POP.

2. Defined Risk: Your loss is capped at the debit paid, making it ideal for small accounts.

3. Access High-Priced Stocks: Trade stocks like Amazon or Google in low-IV environments without needing large capital.

4. Trade-Off Home Runs for Consistency: Sacrifice unlimited profit potential for a higher chance of singles or doubles.

Strategic Tips

• Straddle the Stock Price: For call spreads, buy ITM and sell OTM calls to align breakeven with the stock price.

• Go Deeper ITM for Puts: Increase POP by buying puts further ITM, accepting lower ROC for better breakeven.

• Low-Volatility Environments: Debit spreads shine when implied volatility (IV) is low, as they benefit from potential IV expansion.

• Manage Risk: Avoid OTM or deep ITM spreads, as they skew risk-reward unfavorably.

Key Takeaways

1. Higher POP, Lower Risk: Vertical debit spreads sacrifice home-run potential for a higher probability of profit and defined risk.

2. Flexible Breakeven: Adjust strikes (e.g., deeper ITM puts) to move breakeven in your favor, especially for put spreads.

3. Access Expensive Stocks: Use debit spreads to trade high-priced underlyings with less capital, ideal for small accounts.

4. Bullish or Bearish: Call spreads for upside moves, put spreads for downside, both with capped risk and strong ROC potential.
