In this article, we want to discuss what option spreads are.
This is going to be an introduction to option spreads for beginners, where we learn about what they are and how they work.
Understanding different types of spreads is important before jumping into strategies like when to use them based on being bullish or bearish on a stock. For beginners, terms like ‘bullish’ might add confusion because it assumes knowledge of why you might expect a stock to rise or fall.
We’ll set strategy discussions aside for now and concentrate on understanding what option spreads are, which will make learning about when and why to use them much clearer as you advance.
What is an Option Spread?
An option spread involves buying and selling an equal number of options contracts on the same stock. These can be either call options or put options, not a mix of both. The options must differ in strike prices and / or expiration dates.
Here are some examples using Tesla stock:
Vertical Spreads
These involve buying and selling options with different strike prices but the same expiration date.
- Buy a TSLA call option with a strike price of $150, expiring in one month.
- Sell a TSLA call option with a strike price of $160, expiring on the same date.
- Buy a TSLA put option with a strike price of $150, expiring in one month.
- Sell a TSLA put option with a strike price of $140, expiring on the same date.
Horizontal Spreads (Calendar Spreads)
Also known as calendar spreads, these involve buying and selling options with the same strike price but different expiration dates.
- Buy a TSLA call option with a strike price of $155, expiring in six months.
- Sell a TSLA call option with the same strike price of $155, but expiring in one month.
Diagonal Spreads
These involve buying and selling options with different strike prices and expiration dates.
- Buy a TSLA call option with a strike price of $160, expiring in six months.
- Sell a TSLA call option with a strike price of $165, expiring in one month.
Remember:
Option spreads are when you’re buying and selling the same amount and type of options (calls or puts) on the same underlying stock. What’s different is either the strike prices (vertical spreads), the expiration dates (horizontal / calendar spreads), or both (diagonal spreads).
Credit and Debit Spreads
Trading Context
- Debit Spread: When you initiate a debit spread, you are paying out more money than you are receiving. This results in a net debit from your trading account, meaning your account balance decreases by the amount of the debit. In options trading, a “debit” means you are spending money.
- Credit Spread: Conversely, when you initiate a credit spread, you receive more money than you pay out. This results in a net credit to your trading account, meaning your account balance increases by the amount of the credit. In options trading, a “credit” means you are receiving money.
Accounting Context
In traditional accounting:
- Debit: A debit is an entry that either increases an asset or expense account, or decreases a liability or equity account. It is positioned on the left side of an accounting ledger.
- Credit: A credit is an entry that decreases an asset or expense account, or increases a liability or equity account. It is positioned on the right side of an accounting ledger.
Why the Confusion?
The confusion often arises because in accounting, a debit to a cash account means an increase in cash (which seems like you are receiving money), while a credit to a cash account means a decrease in cash (which seems like you are paying money). However, in trading:
- A debit to your trading account balance (like paying for a debit spread) decreases your cash (you’re spending money).
- A credit to your trading account balance (like receiving money from setting up a credit spread) increases your cash.
To summarize, in the world of options trading:
- Debit = Money Out (You Pay)
- Credit = Money In (You Receive)
Credit Spreads
In a credit spread, you sell an option that generates more premium than the cost of the option you buy. The concept of “credit” comes from the fact that the net transaction results in a credit to your trading account—meaning you receive more money from selling the option than you spend on buying another. Here’s how it breaks down for both calls and puts:
- For Call Options: You sell a call with a lower strike price and buy a call with a higher strike price.
- For Put Options: You sell a put with a higher strike price and buy a put with a lower strike price.
Key Points
- Credit Spread = Selling an option with a more favorable strike (collect more premium) + Buying an option with a less favorable strike (pay less premium).
- Resulting Transaction = Net Credit to your account.
Debit Spreads
A debit spread is an options trading strategy that results in a net cost, or “debit,” to your account. This happens because you’re buying an option that costs more than the option you are selling. Here’s a breakdown of how it works for both calls and puts:
- For Call Options: You buy a call option with a lower strike price and sell a call option with a higher strike price.
- For Put Options: You buy a put option with a higher strike price and sell a put option with a lower strike price.
Key Points
- Debit Spread = Buying an option with a more favorable strike (pay more premium) + Selling an option with a less favorable strike (collect less premium).
- Resulting Transaction = Net Debit from your account.

Example of a Vertical Spread
Let’s run through a practical example comparing the differences between buying Tesla (TSLA) stock outright, buying a call option, and setting up a vertical call spread. This will demonstrate why using vertical spreads can sometimes be a more advantageous option than the other methods, especially in terms of risk management and cost efficiency.
Example Setup Using Tesla (TSLA) Stock
Current Tesla Stock Price: $150
Option 1: Buying Tesla Stock Outright
- Action: Purchase 100 shares of Tesla at $150 per share.
- Cost: $15,000
- Potential Risk: Entire amount of $15,000 if Tesla’s stock goes to zero.
- Potential Reward: Unlimited. Each dollar increase in the stock price increases the investment value by $100.
Option 2: Buying a Call Option
- Option Selected: Buy a call option with a strike price of $150, expiring in one month.
- Cost of the Call Option (Premium): Let’s assume $10 per share, or $1,000 per contract.
- Potential Risk: $1,000 (total premium paid).
- Potential Reward: Unlimited above the break-even point ($160).
- Break-even Stock Price at Expiration: Strike price + premium = $150 + $10 = $160.
Option 3: Setting Up a Vertical Call Spread
- Setup:
- Buy a call option with a strike price of $150, expiring in one month. Assume a cost of $10 per share ($1,000).
- Sell a call option with a strike price of $160, expiring in one month. Assume you receive $5 per share ($500).
- Net Cost (Debit): $1,000 – $500 = $500
- Potential Risk: $500 (the net cost of the spread).
- Potential Reward: Maximum profit is capped. Calculated as the difference between strike prices minus net debit = ($160 – $150 – $5) = $5 per share, or $500 per contract.
- Break-even Stock Price at Expiration: Lower strike + net debit = $150 + $5 = $155.
Why Vertical Spreads Can Be Better
- Lower Cost and Risk: The vertical spread reduces the initial cost from $1,000 to $500 compared to buying a call outright. This also lowers your total financial risk.
- Defined Outcomes: Both potential reward and risk are clearly defined in a vertical spread. You know the maximum amount you can lose ($500) and the maximum profit you can make ($500).
- Reduced Impact of Time Decay: By selling a higher-strike call, you offset some of the time decay on the bought call. The premium received from the sold call compensates for the time decay of the long call, which makes this strategy more resilient to sideways market movements.
- Break-even More Favorable: The break-even point for the vertical spread ($155) is lower than for the bought call ($160), making it easier to start profiting as the stock doesn’t have to rise as much.
Practical Scenarios with ROI Analysis
- Scenario 1: Tesla’s stock rises to $165 at expiration.
- Stock Purchase:
- Profit: $15 per share x 100 shares = $1,500
- Initial Investment: $15,000
- ROI: ($1,500 / $15,000) x 100 = 10%
- Bought Call:
- Profit: ($165 – $160) x 100 = $500
- Initial Investment: $1,000 (premium paid)
- ROI: ($500 / $1,000) x 100 = 50%
- Vertical Spread:
- Maximum Profit Reached: $500
- Initial Investment: $500 (net cost of spread)
- ROI: ($500 / $500) x 100 = 100%
- Stock Purchase:
- Scenario 2: Tesla’s stock is at $155 at expiration.
- Stock Purchase:
- Outcome: Profit of $500 (100 shares x $5 gain per share from the initial $150 purchase price).
- ROI: Approximately 3.33% ($500 profit / $15,000 initial investment).
- Bought Call:
- Loss: $500 (The intrinsic value of the call is $5 per share, or $500 for 100 shares, which is $500 less than the $1,000 paid for the premium).
- ROI: -50% (Loss of $500 on the initial $1,000 investment).
- Vertical Spread:
- Outcome: Profit of $0 (The spread reaches its break-even point; the intrinsic value of the long call at $155 minus the net cost of the spread equals zero profit).
- ROI: 0% (No gain or loss relative to the net debit of $500).
- Stock Purchase:
- Scenario 3: Tesla’s stock drops to $130 at expiration.
- Stock Purchase:
- Loss: $20 per share x 100 shares = $2,000
- Initial Investment: $15,000
- ROI: (-$2,000 / $15,000) x 100 = -13.33%
- Bought Call:
- Loss: $1,000 (full premium lost)
- ROI: -100% (total investment lost)
- Vertical Spread:
- Net Loss: $500 (maximum loss)
- Initial Investment: $500
- ROI: (-$500 / $500) x 100 = -100%
- Stock Purchase:
Summary
These scenarios highlight the different financial dynamics of each trading strategy:
- The stock purchase provides a solid, albeit lower, percentage gain in a rising market but also exposes the investor to substantial capital requirements and significant losses in a falling market.
- The bought call offers substantial leverage (higher percentage gains for smaller moves in stock price) but with the risk of total investment loss if the stock price does not move favorably.
- The vertical spread offers the best risk management, significantly limiting both potential loss and reducing the capital required. While the gains are capped, the ROI is impressive when successful, demonstrating efficient use of capital.
