Assigned Put Options: Understanding the Risks and Rewards

Imagine waking up one morning to find that your brokerage account has fewer cash reserves, but now contains a hefty number of stocks you didn't intend to purchase. For many, this is the introduction to the world of assigned put options.

When it comes to options trading, the term “assignment” refers to the situation in which the writer of an option is obligated to fulfill the terms of the contract. In the case of a put option, it means buying the underlying asset from the option holder at the strike price. But to truly understand the complexities of assigned put options, let's dive deeper.

The Basics: What Is a Put Option?

A put option gives its holder the right, but not the obligation, to sell a specific amount of an underlying security at a set price (the strike price) within a specified period. This can be incredibly useful when a trader expects the stock price to decline. If the stock price falls below the strike price, the put option becomes in-the-money, and the holder has the opportunity to sell shares at a higher price than the current market value.

However, put options can also be sold or written by traders. When you sell a put option, you're essentially making a bet that the stock price will stay above the strike price. If it doesn't, and the option gets exercised, you're obligated to buy the stock at the strike price.

How Does Assignment Work?

When you write (sell) a put option, you're taking on the risk that the buyer may exercise the option if it’s in-the-money. If the buyer exercises the option, you are "assigned," meaning you must buy the shares at the agreed strike price, regardless of the current market price. This process is usually handled automatically by the brokerage if the option is exercised.

For example, imagine you've sold a put option with a strike price of $50 on a stock currently trading at $55. If the stock price falls to $45, the put buyer may exercise their option to sell you the shares at $50. You would then be assigned and required to buy those shares, potentially at a loss.

Why Would You Sell a Put Option?

Selling put options can be lucrative, especially if the market conditions work in your favor. Investors sell puts for various reasons:

1. Premium Income: Every time you sell a put, you collect a premium from the buyer. This is your income regardless of whether the option is exercised or not.

2. Bullish Outlook: If you're confident a stock won't fall below the strike price, selling a put allows you to make money off this belief.

3. Acquiring Stock at a Discount: Some investors sell put options on stocks they actually want to own, but at a lower price. If the stock price declines, the assignment allows them to purchase the stock at a discounted price.

The Risks of Selling Put Options

While selling put options can provide steady income, it comes with significant risks. The primary risk is assignment, where you're forced to buy the stock even if it has significantly dropped in value.

For instance, if you sold a put option on a stock at a $100 strike price, and the stock plummets to $60, you would still be obligated to buy the shares at $100. This can lead to substantial losses, especially if the stock continues to decline.

Additionally, selling puts requires margin, meaning your brokerage will require you to have sufficient funds in your account to cover the potential obligation of purchasing the stock.

Real-Life Example: The Assignment Process in Action

Let's take a real-world example. Suppose an investor named Sarah sells a put option on XYZ Corp with a strike price of $75, collecting a premium of $2 per share. If XYZ remains above $75 until the option expires, Sarah keeps the premium and no assignment occurs.

However, if XYZ drops to $65, the put buyer exercises their option, and Sarah is assigned. She now must purchase 100 shares of XYZ at $75 per share, even though it's only worth $65 in the market. Sarah would end up with a paper loss of $10 per share (not including the premium she collected).

But here’s the catch: Sarah initially sold the put option because she was comfortable owning XYZ stock at $75. In her mind, she’s now acquired shares of a company she believes in, but at a price that's slightly higher than the current market value. Her strategy wasn’t necessarily wrong, but the timing of the market was against her.

Strategies to Mitigate Assignment Risk

To reduce the risk of being assigned on a put option, traders can:

1. Close the Position Before Expiration: One way to avoid assignment is to close the short put position before it reaches expiration. If the option is trading for a small price, you can buy it back and close out your position, thus avoiding the risk of assignment.

2. Choose Strike Prices Wisely: Selecting a strike price that reflects your willingness to own the stock can prevent surprise losses. If you're not comfortable owning the stock at a particular price, don’t sell a put at that strike.

3. Use Cash-Secured Puts: This strategy involves holding enough cash in your account to cover the purchase of the stock at the strike price. This ensures you're prepared financially if assignment occurs.

How to Handle Assignment

Assignment is part of the risk when trading options, and it can happen at any time before expiration. If you're assigned, your brokerage will automatically execute the trade for you. But here's the twist—just because you've been assigned doesn't mean you've lost. In fact, for some investors, assignment is a chance to acquire stock at a desirable price.

Here’s how to think about it: when you're assigned, you’re buying shares of a stock you probably want to own. Even if the current market price is below the strike price, there’s always the possibility that the stock will recover over time.

A disciplined options seller views assignment not as a failure, but as part of the game. The key is to enter the trade with the mindset that you’re fine with buying the stock at the strike price, whether the market agrees or not.

Conclusion: Is Selling Put Options Worth the Risk?

Selling put options can be a profitable strategy, especially for experienced traders who understand the risks. However, it requires a thorough understanding of assignment, as well as the financial capability to buy stocks if the option is exercised. For those willing to take on this responsibility, it can offer a way to generate income while potentially acquiring stocks at a lower price.

But be warned—assignment can lead to significant losses if you're not prepared. Always ensure that you have a clear strategy in place before entering the options market. Whether you're a casual investor or a seasoned trader, understanding how put options work and being ready for assignment is key to long-term success.

In summary, assignment on put options is a double-edged sword. It can either be an opportunity to acquire a stock you like at a discounted price or a costly obligation if the market moves against you. Knowing when to sell puts and how to manage assignment risk is critical in turning this strategy into a profitable one.
