Writing an Option
Writing an option, also known as selling an option, is a key strategy in options trading. When you write an option, you’re essentially creating a new contract that someone else can buy. This can be done with both calls and puts, and it can be a lucrative, albeit risky, endeavor. In this comprehensive guide, we will delve into the intricacies of writing an option, including its mechanisms, different strategies, risks, and potential rewards.
What is an Option?
An option is a financial derivative that provides the buyer the right, but not the obligation, to buy or sell an asset at a predetermined price within a specified period. The main types of options are call options and put options. A call option gives the holder the right to buy the underlying asset, while a put option gives the holder the right to sell it.
The Process of Writing an Option
1. Understanding the Basic Mechanism
When you write an option, you’re essentially giving someone else the right to take a specific action, while you are obligated to fulfill their decision:
- Writing a Call Option: When you write a call option, you are giving the buyer the right to purchase an underlying asset from you at a specified price (strike price) until the option’s expiration date.
- Writing a Put Option: When you write a put option, you are giving the buyer the right to sell you an underlying asset at the strike price until the expiration date.
2. Premium Collection
When you write an option, you collect a premium from the buyer. This premium is the income you earn from taking on the obligation of the contract. It is paid upfront and is yours to keep regardless of whether the option is exercised.
3. Obligation to Fulfill
Your responsibility as the writer is to fulfill the terms of the contract if the option is exercised. For a call option, this means you must sell the underlying asset at the strike price. For a put option, you must buy the underlying asset at the strike price.
Strategies for Writing Options
1. Covered Call
A covered call involves owning the underlying asset while writing a call option on the same asset. This strategy allows you to generate additional income through premiums while still holding onto the asset. Here’s how it works:
- Purchase the underlying asset.
- Write a call option with a strike price above the current market price of the asset.
- If the option is exercised, sell the asset at the strike price (which you likely bought at a lower price).
- If the option is not exercised, keep the premium and the asset.
2. Naked Call
A naked call, which is inherently riskier, involves writing a call option without holding the underlying asset. This exposes the writer to unlimited potential loss since the stock price can theoretically rise indefinitely. Here’s how it unfolds:
- Write a call option with a strike price above the current market price.
- If the option is exercised, purchase the asset at the current market price and sell it at the strike price.
- If the option is not exercised, keep the premium.
3. Cash-Secured Put
A cash-secured put strategy involves writing a put option while holding enough cash to purchase the underlying asset if the option is exercised. This is relatively safer than writing naked options but comes with its own set of risks:
- Write a put option with a strike price below the current market price.
- If the option is exercised, buy the asset at the strike price using the reserved cash.
- If the option is not exercised, keep the premium.
4. Naked Put
Writing a naked put involves writing a put option without setting aside sufficient cash to cover the potential purchase of the underlying asset. This exposes the writer to significant risks if the market price falls drastically:
- Write a put option with a strike price below the current market price.
- If the option is exercised, you must buy the asset at the strike price regardless of your cash situation.
- If the option is not exercised, keep the premium.
Risks Associated with Writing Options
1. Unlimited Loss Potential
Perhaps the most significant risk in writing options is the potential for unlimited losses. For example, if you write a naked call and the price of the underlying asset skyrockets, you may be forced to buy the asset at an exorbitantly high price to sell it at the lower strike price.
2. Margin Requirements
Writing options, especially naked ones, often requires a margin account, meaning you might need to maintain a minimum balance and could be subject to margin calls if your account falls below the required levels.
3. Obligation to Fulfill Contracts
When writing options, you have an obligation to buy or sell the underlying asset if the option is exercised—regardless of current market conditions, potentially leading to significant financial strain.
4. Opportunity Costs
Writing options, particularly covered calls, could limit your profit potential. For example, if you hold a stock that appreciates significantly, but you’ve written a call option with a lower strike price, you may have to sell the stock at the lower price, missing out on higher profits.
Benefits of Writing Options
1. Premium Income
The most immediate benefit of writing options is the income generated from premiums. This can be a reliable way to generate additional revenue, especially in stable markets.
2. Market Entry Strategy
Writing put options can serve as a strategy to enter the market at a lower price. If you have the cash to secure the transaction, selling put options at a strike price you find favorable can either yield premiums or allow you to buy the asset at a lower price.
3. Enhanced Returns
Covered call strategies can enhance returns on a portfolio by generating additional income through premiums, especially if the market remains relatively stable or mildly bullish.
Practical Example of Writing an Option
Imagine you own 100 shares of a stock currently trading at $50 per share and you decide to write a covered call with a strike price of $55 expiring in one month with a premium of $2 per share:
- Current situation: Own 100 shares at $50/share.
- Write a call option: Strike price $55, premium $2 per share.
- Outcome 1 (Stock price ≤ $55 at expiration): The option expires worthless, and you keep the shares and the $200 premium.
- Outcome 2 (Stock price > $55 at expiration): The option is exercised. You sell the shares at $55 per share and still keep the $200 premium.
In both scenarios, you benefit from the premium. However, the upside is capped if the stock appreciates significantly beyond the strike price.

Conclusion
Writing options is a sophisticated trading strategy that can provide significant benefits, including premium income and enhanced returns on investments. However, it also comes with substantial risks, especially if done without proper safeguards such as owning the underlying asset or securing sufficient cash to cover potential obligations.
