Options assignment
- Options Assignment
Introduction
Options assignment is a critical concept for any options trader to understand, particularly those selling options (writing options). It's the process by which a writer of an options contract becomes obligated to fulfill the terms of that contract. This article will provide a comprehensive overview of options assignment, covering the mechanics, factors influencing it, potential outcomes, strategies to mitigate risk, and important considerations for both call and put options. Understanding assignment is crucial for managing risk and maximizing profitability in options trading. This article assumes a basic understanding of Options trading.
What is Options Assignment?
When you *buy* an option, you have the *right*, but not the obligation, to exercise it. When you *sell* (or *write*) an option, you *obligate* yourself to fulfill the contract if the buyer chooses to exercise their right. Assignment happens when the options buyer exercises their right, forcing the options seller to either:
- **For Call Options:** Sell the underlying asset at the strike price.
- **For Put Options:** Buy the underlying asset at the strike price.
This isn't a theoretical exercise; it involves real money and real assets. The assignment process is facilitated by the Options Clearing Corporation (OCC), which acts as the intermediary between buyers and sellers, guaranteeing contract performance. The OCC doesn't randomly assign; it follows a specific procedure (described below). Understanding that the OCC is involved provides a level of security, but doesn't eliminate the risk associated with assignment. It's important to differentiate assignment from exercise. Exercise is the *buyer's* action, assignment is the *result* of that action on the *seller*.
The Assignment Process
The OCC uses a lottery-style system to assign short options. Here's a breakdown:
1. **Exercise Notice:** When an options buyer decides to exercise their option, they submit an exercise notice to their broker. 2. **OCC Notification:** The broker forwards the exercise notice to the OCC. 3. **Assignment Lottery:** The OCC randomly selects a seller (the writer of the option) to fulfill the contract. This selection isn't truly random; the OCC prioritizes sellers with the fewest open contracts of the same strike price and expiration date, aiming to distribute the assignment burden fairly. Sellers with a larger number of open contracts are less likely to be assigned on any single exercise. 4. **Assignment Notice:** The OCC notifies the assigned seller's broker. 5. **Seller Obligation:** The seller is now obligated to fulfill the terms of the contract. For a call option, they must sell the underlying asset. For a put option, they must buy the underlying asset.
This process typically occurs after market close. The assigned seller will receive a notification from their broker detailing the assignment and the required action. It’s crucial to have sufficient funds or the underlying asset available to meet the obligation. Failure to do so can result in penalties and forced liquidation of other positions. Consider the implications of Margin requirements when writing options.
Factors Influencing Assignment
Several factors can increase the likelihood of being assigned:
- **In-the-Money (ITM) Options:** Options that have intrinsic value (i.e., the strike price is favorable compared to the current market price) are much more likely to be assigned than out-of-the-money (OTM) options. For a call option, this means the market price is above the strike price. For a put option, it means the market price is below the strike price.
- **Near Expiration:** As an option approaches its expiration date, the probability of assignment increases dramatically, especially if the option is ITM.
- **Dividend Dates:** For stocks that pay dividends, call options are often assigned just before the ex-dividend date. The buyer wants to own the stock to receive the dividend, so they exercise the call, forcing the seller to deliver the shares. This is a significant consideration for Dividend investing.
- **High Open Interest:** While the OCC tries to distribute assignment fairly, a large number of open contracts can increase the chance of being assigned, even if your position is relatively small.
- **American-Style Options:** American-style options can be exercised at any time before expiration, increasing the risk of early assignment. European-style options can only be exercised on the expiration date.
- **Volatility:** Increased volatility can sometimes lead to increased assignment, as traders attempt to capitalize on price swings. Understanding Implied Volatility is essential.
- **Short Squeeze Potential:** In situations where a stock is heavily shorted, a short squeeze could trigger assignment as buyers attempt to cover their positions.
Implications of Assignment – Call Options
If you've *sold* a call option and are assigned, you are obligated to *sell* 100 shares of the underlying stock at the strike price, regardless of the current market price.
- **Scenario 1: Market Price Above Strike Price (ITM)** – This is the most common scenario leading to assignment. You are forced to sell shares at a lower price than the current market price, resulting in a loss. However, you initially received a premium for selling the option, which partially offsets this loss.
- **Scenario 2: Market Price Below Strike Price (OTM)** – Assignment is unlikely, but possible, especially close to expiration or due to dividends. If assigned, you would still have to sell the shares at the strike price, resulting in a loss.
To fulfill the assignment, you have two main options:
1. **Deliver Shares:** If you already own the 100 shares, you deliver them to the buyer. 2. **Buy to Cover:** If you don't own the shares, you must buy 100 shares in the open market and deliver them. This is known as "buying to cover" and can be expensive if the market price is significantly higher than the strike price. This is why maintaining sufficient capital is critical. Consider using a Covered Call strategy to mitigate this risk.
Implications of Assignment – Put Options
If you've *sold* a put option and are assigned, you are obligated to *buy* 100 shares of the underlying stock at the strike price, regardless of the current market price.
- **Scenario 1: Market Price Below Strike Price (ITM)** – This is the most common scenario leading to assignment. You are forced to buy shares at a higher price than the current market price, resulting in a loss. You initially received a premium for selling the option, which partially offsets this loss.
- **Scenario 2: Market Price Above Strike Price (OTM)** – Assignment is unlikely, but possible, especially close to expiration. If assigned, you would still have to buy the shares at the strike price, resulting in a loss.
To fulfill the assignment, you are simply required to purchase 100 shares of the underlying stock at the strike price. This can be problematic if you don't have the capital to make the purchase. Strategies like a Cash Secured Put can help manage this.
Strategies to Mitigate Assignment Risk
Several strategies can help reduce the risk of unwanted assignment:
- **Rolling the Option:** Before expiration, you can "roll" the option to a later expiration date or a different strike price. This involves buying back the original option and selling a new option with different terms.
- **Closing the Position:** Before expiration, you can simply buy back the option you sold, closing your position and eliminating the risk of assignment. This will cost you money (the difference between the premium you received and the price you pay to buy it back).
- **Writing Out-of-the-Money (OTM) Options:** Selling OTM options reduces the likelihood of assignment, as they have less intrinsic value. However, the premiums received are typically lower.
- **Choosing Expiration Dates Carefully:** Avoid selling options that expire around dividend dates or during periods of high volatility.
- **Spreads:** Using options spreads, such as bull call spreads or bear put spreads, can limit your potential losses and reduce the risk of assignment. Research different Options Spread strategies.
- **Maintaining Adequate Capital:** Ensure you have sufficient funds available to cover potential assignment obligations.
- **Understanding the Greeks:** Paying attention to the Delta of an option can give you an idea of its sensitivity to price changes and the probability of assignment.
Tax Implications of Assignment
Assignment has tax implications. The profit or loss from assignment is typically treated as a short-term capital gain or loss if the option was held for less than one year, and as a long-term capital gain or loss if held for more than one year. The premium received when selling the option is also factored into the calculation. Consult with a tax professional for specific advice.
Avoiding Assignment: A Summary of Best Practices
- **Monitor Your Positions Closely:** Keep a close eye on your open options positions, especially as they approach expiration.
- **Understand the Underlying Asset:** Be aware of potential events that could trigger assignment, such as dividend payments or earnings announcements.
- **Plan for the Worst-Case Scenario:** Always have a plan in place to fulfill your obligations if assigned.
- **Don't Overleverage:** Avoid writing options with more capital at risk than you can afford to lose.
- **Continuous Learning:** Options trading is complex. Stay informed and continuously learn about new strategies and risk management techniques. Utilize resources like Technical Analysis and Chart Patterns to improve your trading decisions.
- **Consider using risk management tools:** Utilize tools such as Stop-Loss Orders to limit potential losses.
