Covered Options: Understanding the Basics of Covered Calls and Puts

Highlights:

• A written option is covered when the writer has an opposing position in the underlying security.
• Short calls are covered by owning the underlying stock or holding a long call with a similar or lower strike price.
• Short puts are covered if the writer has a short position in the stock or a long put with a similar or higher strike price.

Introduction

In the world of options trading, the term “covered” is used to describe a specific strategy where an investor holds an opposing position in the underlying security, providing a layer of protection against potential losses. This strategy is most commonly applied to short options positions, such as short calls and short puts. To fully grasp the concept of covered options, it’s essential to understand how these positions work and how they mitigate risk.

What Does Covered Mean?

A written option is considered covered when the writer, or seller, holds an equivalent position in the underlying security that offsets potential losses from the option position. This strategy aims to ensure that, if the option is exercised, the writer has the necessary resources to meet their obligations. For example, when an investor writes a short call option, they are betting that the price of the underlying asset will not rise above a certain point. However, should the price rise, the investor could face significant losses. To protect against this, the investor can “cover” the short call by owning the underlying stock.

Covered Short Calls

A short call option is considered covered if the writer owns the underlying stock in the same amount as the number of contracts they have written. This means that if the option is exercised and the buyer chooses to purchase the stock, the writer can deliver the stock they already own, avoiding the need to buy it at the market price. This reduces the risk of an uncovered call option, where the seller might be forced to buy the stock at a higher price than the current market value, leading to a loss.

Alternatively, a short call can also be covered if the writer holds another call option on the same security with a strike price that is equal to or less than the strike price of the short call. This strategy is called a "call spread" and limits the potential losses on the short call position.

Covered Short Puts

Similarly, a short put option can be covered by holding a short position in the underlying stock, or by holding a long put option with a strike price equal to or greater than the strike price of the short put. This type of coverage ensures that the writer can meet their obligations in the event the put option is exercised, meaning they will be required to buy the underlying stock at the agreed-upon price.

If the underlying stock’s market price falls below the strike price of the short put, the option holder may exercise the option, forcing the writer to purchase the stock. If the writer has an equal or greater long put position, they can potentially offset losses through the price difference between the short put and the long put.

Margin Requirements and Covered Positions

The concept of “covering” is not only essential for risk management but also for meeting margin requirements. In the case of margin accounts, exchanges and brokers typically require traders to have a covered position in order to reduce the risk of the trade. If the position is not covered, the trader may face a margin call, which could require additional capital to cover potential losses. Therefore, when writing options such as short calls or short puts, ensuring that the position is covered is critical for both risk management and regulatory compliance.

Benefits of Covered Options

The main benefit of using covered options strategies is the reduction in risk compared to uncovered options positions. By holding the appropriate counter-position, traders can limit the potential for significant losses while still participating in options markets. Covered calls, for example, are often used by investors to generate additional income on stocks they already own. Similarly, covered puts can be used to potentially acquire stocks at a lower price than the current market value, with the added benefit of premium income.

Moreover, covered options strategies tend to be more conservative and are typically employed by traders with a more risk-averse approach. These strategies may not provide the same high-reward opportunities as uncovered positions, but they offer a more controlled risk profile.

Conclusion

In conclusion, covered options are a fundamental strategy in options trading, offering a way for investors to manage risk while still participating in the market. By holding the appropriate opposing position—whether through owning the underlying stock or using other options—the writer of the option can effectively limit potential losses. Whether dealing with short calls or short puts, understanding how to cover these positions is essential for any trader looking to reduce exposure and safeguard their investments.
