The Psychology of Expiry Fridays: How Traders Self-Sabotage

Don’t allow Expiry Fridays to continue to screw up your hard week of options trading!

Our guide will explain why Expiry Fridays is a psychological minefield for many traders, how emotions override logic as contracts approach expiration, and how you can begin overcoming the mental traps and common mistakes that many traders experience and make when the end of the week draws near.

What Are Expiry Fridays?

When you hear someone talk about “Expiry Fridays” or a “Friday expiration,” they are referring to the expiration date that is typical of weekly options contracts. They tend to expire on the Friday of the week they’re introduced into the market. Weekly options contracts differ from monthly contracts in that they are suited for short-term strategies and offer the opportunity to trade more frequently.

Options Expiries Compared

• Weekly Options: Expire on Friday of the same week
• Monthly Options: Expire on the Saturday after the third Friday of the month
• Quarterly Options: Expire on the final business day of each quarter (March, June, September, and December)

Why Fridays Are Important in Trading

Why do Fridays matter so much when you’re trading options contracts online? There are several reasons, including a profound impact on liquidity and other factors like volatility or decision pressure. We’ll take a deeper dive into some of these aspects of Fridays and the impact they can have on traders or investors:

Weekly Options

• Time Decay Factor—Because weekly options contracts expire the Friday of the same week, there is much less time for the position to become profitable, which makes the premium much lower for traders who enter these positions. Time decay has a more significant impact on these contracts compared to monthly or quarterly options because the time value is more susceptible to quick erosion.
• Trading Volumes Ticks Up on Fridays—For weekly options, there’s a massive influx of trading volume on Fridays right before expiration as traders scramble to lock in profits, roll out to further expiration, or mitigate losses on their positions. Traders need to be aware of this surge, as it can have a significant impact on stock prices in the eleventh hour on Fridays.
• Shorter Time Horizon—Because weekly options have a shorter window to turn a profit, scalpers, and traders whose strategy is based on price speculation can have a field day with these contracts. They work well with short-term trading strategies, allowing traders to capitalize on market events or temporary trends that result in a temporary change in the stock price.

Monthly Options

• Longer Time Horizon—Monthly options expire the Saturday following the third Friday of the month. If Friday falls on a bank holiday, the expiration date is moved to the day before, which is Thursday. Traders have a month to lock in a profit on monthly options, which means they pay a larger premium for the increased time value, but they have a more comfortable window that is well-suited to long-term strategies.
• The Impact of Market Makers and Smart Money—Because there’s more time to deal with monthly options, many smart money traders and institutional investors will do a lot of hedging activity on a large number of contracts. This can have a significant impact on the price of the underlying asset, potentially leading to increased market volatility or unexpected price fluctuations in the stock or other securities.
• Pin Risks Near the Third Friday of the Month—The price of the underlying asset has a tendency to gravitate towards strike prices that have an abundance of open interest as the expiration date draws near. Traders need to be cautious with monthly options as “pinning” can occur around the third Friday. For options sellers, “pinning” can create uncertainty about whether their options will be assigned to them or if they need to buy or sell the underlying.

Key Terms Revisited

You may already be familiar with many of these terms. Still, for those unfamiliar with the concepts, we’ve included a brief refresher course below that covers the key principles and ideas surrounding options contracts and their expiration dates.

• Time Value—A representation of the portion of an option’s premium that refers to the time remaining until the option contract expires. Time value is the amount the trader is willing to pay for the opportunity to see the option increase in value before the expiration date is reached.
• Theta Decay—Also known as time decay, it’s a risk measure that refers to the gradual decrease in the value of options contracts as they approach their expiration date. Theta decay reflects the loss of time value that is bound to happen with any options contract you take on as a trader.
• Delta—A measurement of the option’s price sensitivity to changes in the underlying asset’s price.
• Gamma Risk—The risk associated with changes in the option’s delta, which is created by fluctuations in the value of the underlying asset.
• Pinning the Strike—This is a phenomenon where the underlying asset’s price tends to move closer to the strike price, especially with options that are heavily traders (high open interest). Pin risk can create uncertainty for traders about whether they will be assigned or if they will have to buy or sell the underlying asset.

The Mental Game—Why Expiry Fridays Mess With Your Head

Although it seems like a straightforward setup and concept for options traders, there’s no denying that the Friday expiration dates can cause some traders’ heads to spin due to the numerous possibilities that could occur on Friday or the days leading up to it. We’ll dig a bit deeper into these dilemmas to show you how easy it can become for traders to make some major psychological mistakes around Expiry Friday.

Top 5 Psychological Mistakes Traders Make on Expiry Fridays

Let’s review some of the significant mistakes that option traders can make when preparing for the Friday expiration date on their options contracts, whether they are weekly, monthly, or quarterly setups. There is an entire array of potential missteps that could occur, where traders effectively miss out on profiting or end up taking more in losses than they should have.

• Loss Aversion—Some traders might hold onto a losing trade for too long because they feel it could turn around before the expiration date. The entire mentality can be summed up like this: “I can’t close this now, I might still win.” This kind of trader is afraid of losing and wants to see the trade through to the end to determine if it could still profit, whereas they should close out the losing trade earlier to avoid further losses.
• Sunk Cost Fallacy—Another psychological trick with similarities to the one we just discussed is the “sunk cost fallacy,” where traders hold a position because they have invested time, money, or effort into the trade. It’s best to close out a losing trade as soon as possible to limit further losses, but some traders make the mistake of seeing it through to the end because of what they’ve already invested in the endeavor.
• Overconfidence Bias—This phenomenon occurs when traders have overconfidence in their ability to trade, trusting their knowledge of the markets and their skill in navigating specific investments more than they should. Doubling down or overtrading on a losing week can lead to financial disaster.
• FOMO—This stands for the “fear of missing out” on traders and other investment opportunities. It’s a form of emotional trading like this that can lead traders to take on more positions than they can realistically handle. FOMO can cause traders to become overleveraged—they’re using too much borrowed money compared to their account balance.
• Regret Aversion—A psychological bias that has traders making decisions to avoid the pain of making incorrect decisions that could hurt later on. Regret aversion can lead traders to avoid opportunities, hold onto positions for too long, create reluctance to sell winning stocks, and gravitate toward safe investments, which don’t always result in long-term growth.

Real-Life Scenarios—How Traders Self-Sabotage

How could some of these scenarios play out in the real world in a live trading market where real money is at stake? Take a look at a few of our hypothetical vignettes below, which effectively illustrate how traders can potentially self-sabotage around the time their options contracts expire on Fridays.

“The YOLO Friday Trader”

This is the type of trader who enters options with little to no strategy and treats the whole affair like gambling.A hypothetical scenario is the traders taking on a Zero Days to Expiration contract in the hopes of locking in rapid gains. However, this can be a risky maneuver, and its success rate depends on thorough market research and confirmation from technical indicators that the market direction is correct.

These trades have very little time value, and they can be challenging to adjust, especially when dealing with unexpected market movements. A trader who goes all in on zero DTE could risk a total loss. Some of the factors at play that can increase the risk of trading on 0DTE stocks include the following:

• Impulsiveness on the trader’s part can lead to overleveraging.
• Another risk of impulsiveness is taking on bad trades (fueled by FOMO), which can significantly amplify losses.
• FOMO can be easy to fall in with the allure of quick profits that come from 0DTE stocks.
• The pursuit of quick profits can lead traders to take on excessive risks or engage in irrational trades.

“The Theta Bleed Ignorer”

There’s the kind of trader who ignores the fact that their position is losing its time value due to time decay (theta decay). While it seems dumb to do this, there are several psychological reasons a trader would do such a thing, including the following:

• The trader holds onto the position, hoping that it will turn around in time for the contract’s expiration date.
• Some traders are afraid of losses, and they may be paralyzed by indecision about what to do when the markets are moving against them.
• Traders might enter a trade without a clear sense of risk management, failing to plan out how much money they want to secure in profit or the maximum loss they’re willing to accept.
• Irrational decision-making can occur if the trade relies too heavily on emotions like overconfidence, fear, or greed, which can lead to holding onto a losing position for far longer than necessary.

Traders who ignore theta decay and time value in their options contracts may hold onto their losing trades for too long (for any of the reasons listed above), which could result in significant losses or missed opportunities for the trader to invest their capital in more promising positions.

“The Revenge Trader”

For our following scenario, you have a trader who is frustrated by the markets moving against their trades and hopes to recoup the losses over an entire week in one afternoon, right before the Friday expiration date. To be clear, this “strategy” is based on emotion and doesn’t typically fall within the parameters of a sound trading plan. It’s a move that’s impulsive and can be irrational because there’s no regard for risk management practices, such as correct position sizing or stop-losses.

What triggers the revenger trading pattern that so many people fall into when they begin letting their emotions guide them?

• Loss aversion can play a significant role in this context. Traders prefer to take on an irrational risk because they can’t deal with the pain of losing.
• Pride can be a contributing factor to revenge trading. The trader doesn’t like having a failure on the books, and their pride will push them to recoup the losses.
• The primary force driving revenge trading tends to be the anger and frustration that comes with losses. Traders will lash out irrationally at the markets to get back at them for the loss. They barrel ahead with a recoup strategy without considering risk factors.

The Role of Market Makers and Pin Risk

Market makers act as intermediaries in financial markets by quoting buy and sell prices for particular securities, which plays a crucial role in the markets. Their actions facilitate smooth and efficient trading for other traders in the options market and those dealing with various assets or securities. The primary role market makers play is helping buyers and sellers connect with each other. It helps everything in the long run, as it’s much easier to find liquid options that can be traded relatively quickly and at decent prices.

The Ultimate Responsibilities of the Market Makers

All told, the market makers are responsible for the following conditions that attempt to keep the options market at the stablest equilibrium possible:

• Market makers narrow the difference between the bid and ask prices.
• They respond to supply and demand imbalances.
• Market makers ensure that buyers and sellers are available by placing buy and sell orders on their personal inventory of securities. This leads to a liquid market.
• They connect buyers and sellers to ensure that market participants can enjoy efficient transactions in larger markets, such as the options market.
• The role of the market makers is to help traders and investors find fair prices for the options or underlying assets they want to trade.

Why Market Makers May “Pin” a Stock to a Certain Strike

Because market makers have a duty to the options market to facilitate transactions as liquid as possible between buyers and sellers, they may choose to pin stock to a specific strike price around the time of expiration. Market makers decide to do this to deal with hedging strategies being used by smart money traders or institutional investors. Market makers have a significant incentive to minimize losses on the options positions they hold, so they keep the strike price near the strike price of an option that is heavily traded by the trading community.

The Illusion of Patterns vs. Real Dealer Positioning

“Pinning” causes the stock price to drift closer to the strike price close to the expiration date. This can become disorienting and confusing for retail traders because it creates uncertainty around whether the options will be exercised or not. Traders who are unfamiliar with pin risk can often mistake a drifting stock price for a legitimate market trend, which could lead them to make a trading decision that’s not rooted in reality.

How to Master Your Mindset Before Expiry Fridays

As a trader who is becoming familiar with the risks that could arise around the Friday expiration date, how can you better prepare both mentally and in your trading plan to master how to maneuver your traders or investments during this time? Check out some of the best tips and actionable advice we know to deal with this phenomenon.

5 Rules Mentally Tough Traders Follow on Expiry Fridays

• Build a Written Plan Before Friday—The core of this is having a trading plan in place that outlines how much you’re willing to risk on the deal (position size), how much you’re willing to take in profit (take-profit orders), and the max amount you’re willing to lose (stop-loss orders).
• Set Profit/Loss Rules for Thursday Night—Going off of the last point, you can wait as late as Thursday night to establish your take-profit and stop-loss levels so your trade doesn’t automatically close too soon before the expiration date. Set these parameters to lock in wins but also to minimize the amount of potential risk you might take if the trade goes south.
• Use Conditional Orders—To remove emotion from exits, traders should set up conditional orders. These orders are executed based on the trader’s specific criteria, such as the stock price, the price of another asset, and market conditions at the time. Once the parameters are met, the conditional order will be triggered and executed automatically, taking emotions from the equation.
• Avoid Chasing or Entering New Trades Friday Afternoon—Unless it’s part of your system, you should generally avoid entering new trades on Fridays because it only gives you a small window of time to become profitable.
• Consider Reducing Position Size or Going Flat on Friday Mornings—This is a valid risk management approach that options traders can take on Friday mornings to mitigate the risk of weekend volatility, which can disrupt your trades if negative news releases after the markets close on Friday. It’s a prudent strategy that can work well in dealing with this potential risk, but it’s no guarantee, as different stocks will perform differently based on various factors.
