Trading Options Spreads: How and Why

One of the biggest mistakes I see newer options traders make is to run strategies that are long-only. A long call or a long put, rather than a spread. That's not to say such strategies cannot work, but I think they are often a riskier way to express a view, offering little flexibility for rolling positions without taking a significant hit.

I like to encourage options traders to consider employing spreads, because we can reduce our overall risk and debit cost, allowing for greater flexibility.

Today we'll talk about vertical spreads, calendar spreads, and diagonal spreads, in part because of their ability to mitigate risks compared to simply going long on calls or puts.

Vertical Spreads

Definition and Structure

A vertical spread involves buying and selling options of the same type (either calls or puts) with the same expiration date but at different strike prices. The most common usage of this strategy is as follows:

1. Bull Vertical Spreads: Buying a call at a lower strike price and selling a call at a higher strike price.

2. Bear Vertical Spreads: Buying a put at a higher strike price and selling a put at a lower strike price.

Risk Management

The primary advantage of vertical spreads is their defined risk nature. The maximum loss is limited to the initial debit paid (for a debit spread) or the difference between strike prices minus the credit received (for a credit spread). This contrasts starkly with long calls or puts, where the potential loss can be the entire premium paid.

Lower Debit and Exposure

Vertical spreads often require less capital outlay than purchasing a standalone option. By selling an option alongside buying one, the trader offsets some of the initial costs. This strategy effectively reduces overall market exposure, making it a more conservative approach than a long single option position.

Calendar Spreads

Definition and Structure

Calendar spreads, also known as time spreads, involve the simultaneous purchase and sale of two options of the same type and strike price but with different expiration dates. Typically, a trader will:

• Buy an option with a longer-term expiration.

• Sell an option with a shorter-term expiration.

Advantage in Volatility and Time Decay

Calendar spreads can capitalize on differences in time decay (theta) and implied volatility between the short-term and long-term options. As the near-term option decays faster, the trader benefits if the stock remains relatively stable. This is less risky compared to long calls or puts, where the value can erode quickly with time decay if the market doesn’t move favorably.

Reducing Initial Costs

Like vertical spreads, calendar spreads lower the initial investment compared to buying a single long-term option. The premium received from selling the short-term option offsets part of the cost of the long-term option, reducing overall financial exposure.

Diagonal Spreads

Definition and Structure

Diagonal spreads are a hybrid of vertical and calendar spreads. This strategy involves:

• Buying an option with a certain strike price and a longer expiration.

• Selling an option with a different strike price and a shorter expiration.

Flexible Adjustment and Risk Control

Diagonal spreads offer a blend of price and time strategy, allowing traders to benefit from both directional market moves and time decay. The disparity in strike prices and expiration dates offers more flexibility to adjust the position in response to market changes. This flexibility provides a layer of risk management not present in simple long options positions.

Capital Efficiency

Diagonal spreads can be more capital efficient than straightforward long options. They reduce the overall cost of the trade and limit the potential loss to a predefined amount, much like vertical and calendar spreads.

Closing Thoughts

Vertical, calendar, and diagonal spreads provide traders with sophisticated strategies that can reduce risk and capital outlay compared to simply going long on calls or puts. These strategies can provide greater flexibility for rolling positions and as a result are less sensitive to time than typical options strategies.

By integrating these strategies into their trading arsenal, traders can gain more control over their risk exposure, benefit from time decay and volatility differences, and achieve a more balanced and diversified approach to options trading.

As with any options strategy, understanding the nuances and risks involved is crucial. Traders should thoroughly educate themselves and consider seeking professional advice from a qualified financial advisor before diving into options trading of any kind.
