The Smarter Way to Trade Direction With Options

Long Vertical Spreads for Directional Trading

Key Concepts:

• Long Vertical Spread: An options strategy involving buying and selling options of the same type (calls or puts) with the same expiration date but different strike prices.
• Theta: The rate of time decay in an option's price. Long options experience negative theta (value decreases as time passes), while short options experience positive theta (value increases as time passes).
• Bull Call Spread (Long Call Spread): A strategy used when expecting a stock price to increase.
• Bear Put Spread (Long Put Spread): A strategy used when expecting a stock price to decrease.
• Defined Risk: A strategy with a known maximum potential loss.
• Net Theta Neutral: A position where the positive and negative theta effects largely offset each other.
• Probability of Profit (POP): The likelihood that a trade will be profitable at expiration.

The Problem with Long Options

The fundamental challenge with simply buying calls or puts (long options) for directional trading isn’t being correct about the direction of the stock, but rather the impact of time decay, or theta. While long options offer unlimited profit potential and limited risk (the premium paid), the value of the option erodes daily due to theta. This means traders are constantly fighting against the clock, needing the stock to move quickly enough to offset the decaying value. As stated, “When you buy an option… time is always working against me.” This constant erosion reduces the probability of profit, even if the directional prediction is accurate. A naked long call or put, even at the money, typically has a probability of profit less than 50%, often around 46-44%, due to this theta drag.

Introducing Long Vertical Spreads

Long vertical spreads offer a solution to mitigate the negative effects of theta while still allowing for directional trading. These are two-legged strategies, meaning they involve both buying and selling options. Specifically, a long vertical spread consists of:

• Same Underlying Stock: Both options are on the same stock.
• Same Expiration Date: Both options expire on the same date.
• Same Option Type: Both options are either calls or puts.
• Different Strike Prices: One option is bought (the long option) and one is sold (the short option) at different strike prices.

Unlike short vertical spreads where the short option drives the strategy, in a long vertical spread, the long option dictates the directional bias. The trader pays a debit for this spread, aiming for the overall value to increase so it can be sold for a profit.

Types of Long Vertical Spreads

There are two primary types:

1. Long Call Spread (Bull Call Spread): Used when anticipating a price increase. Involves buying a call option at a lower strike price and selling a call option at a higher strike price.
2. Long Put Spread (Bear Put Spread): Used when anticipating a price decrease. Involves buying a put option at a higher strike price and selling a put option at a lower strike price.

Theta Neutrality and Spread Construction

The key benefit of a long vertical spread is its potential to become theta neutral. While long options have negative theta, short options have positive theta. By combining the two, the positive theta from the short option can offset the negative theta from the long option.

The preferred construction method, as practiced at Tastytrade, involves “straddling” the current stock price. This means:

• Long Call Spread Example: If a stock is at $100, buy a call at the $98 strike and sell a call at the $102 strike.
• Long Put Spread Example: If a stock is at $250, buy a put at the $255 strike and sell a put at the $245 strike.

This structure aims to create a position where the theta effects are largely neutralized. The long option provides the directional exposure, while the short option helps manage the time decay.

Probability of Profit and Risk Management

Long vertical spreads typically result in a roughly 50/50 probability of profit, effectively a coin flip. This is an improvement over naked long options, where the probability of profit is often lower due to theta decay. The strategy is also defined risk, meaning the maximum potential loss is known upfront.

Proper position sizing is crucial, adhering to the guidelines for defined risk strategies: 1-3% of net liquidating value per trade. For example:

• $50,000 account: $500 - $1,500 risk per spread.
• $100,000 account: $1,000 - $3,000 risk per spread.
• $20,000 account: $200 - $600 risk per spread.

Managing a Long Vertical Spread

Management is relatively straightforward:

• Profit Target: Aim for 50% of the maximum potential profit.
• Expiration: If the profit target isn’t reached, hold the position until expiration, accepting the maximum loss if necessary.
• Rolling: If, with 21 days until expiration, the trade is near breakeven, consider rolling the spread forward for a credit.

Conclusion

Long vertical spreads provide a strategic approach to directional trading in options, mitigating the detrimental effects of theta decay. By combining a long and short option, traders can achieve a more theta-neutral position with a roughly 50% probability of profit and defined risk. As the speaker concludes, “If you want to trade direction, then by all means, go for it. Just do it strategically with something like a long vertical spread.” This strategy allows traders to express a directional view without being overly penalized by the passage of time.
