Understanding the concept of Pin Risk is crucial for any investor dealing with options trading, particularly from the sell side. This guide intends to simplify this complex concept and illustrate its significance in the trading world.

What is Pin Risk?

Pin Risk emerges when a stock settles close to the strike price at its expiration. It can be seen as the risk associated with the unpredictability of what the option holder is going to do prior to expiration. The lingering question is whether the option will finish ‘in the money,’ ‘at the money,’ or ‘out of the money.’ This uncertainty leaves the option seller unsure if they’ll have a stock position and need to deliver shares or purchase them.

The Impact of Pin Risk

Investors may have varying perceptions towards Pin Risk. Some may be unfazed by the assignment, while others would prefer to know their position come Monday morning after expiration. The closer the stock trades to the strike price, the higher the level of uncertainty, leading to possible actions by the seller.

Option sellers must always be prepared for some level of uncertainty, which can also include overnight risk, the need to commit capital when necessary, and even potential after-hours market fluctuations.

A Practical Example

To understand Pin Risk more clearly, consider this scenario. An investor shorts the $270 put, with shares trading slightly above that value heading into the closing bell. The investor watches the market until the closing bell, seeing the underlying shares remain above $270. Despite this, they find themselves assigned, leading to the purchase of $27,000 worth of shares at a strike price of $270.

This could result in a negative surprise on Monday morning, where they now own a hundred shares, and its trading value has decreased by four or five dollars. The exercise right of the option holder is not necessarily tied to where the stock is versus the strike price at closing on expiration day. Even if it’s not in their financial best interest, the option holder can choose to exercise.

Prudent investors holding options close to the strike price might watch after-hours activity to gauge market movements. However, after-hours activity could lead to unexpected assignments.

Avoiding Unwanted Assignments

The only foolproof way to eliminate the possibility of an unwanted assignment is to not have an assignable position. While the temptation to squeeze every penny out of a trade is understandable, it’s not always possible without taking on an unnecessary amount of risk. The safest strategy to dodge an unwanted assignment is to buy the close and exit the position.

Usually, option buyers have about 60 to 90 minutes post-closing bell to notify their brokerage firms about their exercise intentions. This timeframe varies across firms but provides some insight into the time buyers have to watch the market, observe after-hours activity, and make a decision, irrespective of the option’s final moneyness at the closing bell.

Conclusion

Pin Risk in options trading can be complex to grasp, yet understanding it is essential for option sellers. By keeping the concepts and strategies outlined in this guide in mind, you can navigate the potential pitfalls and uncertainties associated with pin risk, and make more informed decisions in your trading activities.
