What Is an Options Chain?

An options chain is a real-time listing of all available options contracts for a particular stock which includes all call and put options. The options chain also shows traders the strike prices, premiums, open interest, and an estimation of the implied volatility. This tool can help traders understand potential price movements and the overall market sentiment toward specific stocks.

Options chains are structured with two columns. Calls are displayed on the left side, and puts are displayed on the right side. With the call options representing the right to buy an underlying asset at the strike price and put options representing the right to sell at the strike price, these two columns of an options chain separate the bullish and bearish options within the chain.

If you’re interested in accessing real option chains to find out what they look like and where the important information is located, you can find them on broker platforms like ThinkorSwim, Interactive Brokers, or Tastytrade. You don’t even have to create a new account or become a member to do this—simply visit the websites and search for an example of an options chain!

Key Components of an Options Chain

We touched on this briefly in the prior section, but we’d like to cover in more detail the key components of an options chain to give you an understanding of how you can use this tool to your advantage. The main sections that appear on an options chain include the following:

• Strike Price: This is the predetermined price at which the holder of an option contract can buy or sell the underlying assets, essentially the price at which the option can be exercised. The strike price is a key factor determining the moneyness of an option (in-the-money or out-of-the-money).
• Bid Price: This represents the highest price a buyer is currently willing to pay for an option contract. The bid price indicates the best available price at which a trader is willing to purchase that option at that current moment.
• Ask Price: The opposite of the bid price, the asking price is the lowest price a seller is willing to accept for an options contract. It’s the minimum price a buyer must pay to purchase a specific option from one of the market’s sellers.
• Last Price: This refers to the most recent price that a specific option contract was traded at, the last recorded sale price for that particular contract. The last price, paired with the bid and ask price offers a clear picture of the current trading range for traders and investors.
• Open Interest (OI): The total number of outstanding contracts that are currently active—they haven’t been closer or exercised. Open interest indicates how many open positions there are for a certain option at a particular strike price and expiration date.
• Implied Volatility (IV): A measure of expected future volatility, the market’s expectation of how much the price of the underlying asset is likely to fluctuate over the life of an options contract. Higher implied volatility indicates a greater price fluctuation.
• Volume: The total number of contracts traded specific underlying security in a single trading day. It shows how much activity or interest there was in that particular options contract, showing that higher volume signifies better liquidity potential for easily entering and exiting positions.
• Expiration Dates: The specific date and time when an options contract becomes invalid, and the trader can no longer exercise it. There are different available timeframes for the options contracts. After the expiration date, the option becomes worthless and expires.

Calls vs. Puts—What to Look For

Call options give traders the right to buy a stock, and they’re used when they expect the stock price to rise. On the other hand, put options give traders the right to sell a stock, and these are used when traders expect the stock price to fall. Call options can profit when the stock price exceeds the strike price. However, calls and puts run the risk of expiring as worthless which ultimately results in traders losing the premium they paid for the investment. Also, selling calls and puts can result in losses that are greater than the price the trader paid for buying them.

Interpreting Moneyness

In-the-Money (ITM): Call options are in-the-money when the market price is higher than the strike price. Put options are in-the-money when the market price is lower than the strike price. ITM options have positive intrinsic value, which means they can be exercised right away for a profit.

• At-the-Money (ATM): The option’s strike price is exactly equal to the current market price of the underlying asset. The option, therefore, has no intrinsic value, but it does hold time value. It’s right on the line between being in-the-money and out-of-the-money.
• Out-of-the-Money (OTM): This is where an option’s strike pierce is not favorable enough to provide a profit if the contract is exercised immediately.

Understanding the Greeks in an Options Chain

To determine the various risk factors of each option contract, traders use a set of financial metrics called the Greeks to examine each dimension of risk. These metrics don’t guarantee exact option premium changes; they are great tools that options chains include to help traders determine the right value of an option contract. The Greeks help traders or investors to predict how an option’s price will shift with the changing market conditions.

• Delta: A measurement of how much the option’s price will change for every $1 difference in the price of the underlying asset.
• Gamma: A measurement of how much the delta will change when the price of the underlying asset changes.
• Theta: A measurement of how much the option’s price will drop as the expiration date gets closer.
• Vega: A measurement of how much the option will change when there are major price shifts in the underlying asset.
• Rho: A measurement of how much the option’s price will change for a 1% change in the risk-free interest rate.

Real-World Example

Let’s look at how traders could use the Greeks when choosing contracts from an options chain. A trader might be looking for greater exposure to the underlying asset’s price movement, so they’d be likely to choose an option contract with a higher delta value. They can choose such a contract by using the delta “Greek” to find out if it has a higher or lower delta value.

How to Analyze Liquidity and Bid-Ask Spreads

Liquidity is a measure of how easily an asset can be converted to cash or how easily a company can pay its bills. Companies and businesses that can meet their obligations are considered liquidity, and they typically don’t need to borrow money. In the context of options trading, it refers to how quickly and easily a trader can enter or exit positions. Ideally, you want to find liquid options, so you’re able to get into positions at a good price and leave them when needed to lock in a profit.

To identify liquid options in an options chain, you can begin by looking at the following metrics:

• Open Interest: This metric is used to track the number of contracts open on each strike and right. Traders can use open interest to gain insights into the price movements and demand of an option, essentially finding out how quickly and easily these options can be bought or sold.
• Volume: The daily trading volume is a great indicator of an option contract’s liquidity. Higher volumes usually mean that an options contract is more liquid, which is desirable for traders who want to enter and exit positions easily at the desired price level.
• Narrow Bid-Ask Spreads: The bid-ask spread is the difference between the bid and ask price of an asset that’s close together. When the bid-ask spreads are narrow, it can indicate high demand and market efficiency. In other words, these options are much more liquid.

Illiquid options are difficult to buy or sell quickly and efficiently, while liquid options are positions that are easy to enter and exit quickly. If you find options contracts that have little to no open interest, wide bid-ask spreads, or low trading volume, it’s a good sign that you’ve stumbled upon some illiquid options contracts. What you’re looking for (to trade as efficiently as possible) are options that have a higher level of open interest, narrow bid-ask spreads, and higher trading volume.

Spotting Unusual Options Activity Like a Pro

Unusual options activity (UOA) is a sudden increase in the number of options contracts traded for a certain stock. It’s often characterized by large spikes at one or two strike prices, and it’s identified when the volume of a trader is much higher than the existing position. Spotting unusual options activity is one of the main keys to taking advantage of market trends, and it’s all reported on each day’s options chain for your convenience.

Unusual options activity can indicate that institutional investors or smart money traders are making large bets on the future price of a certain stock. This common phenomenon can indicate two key things: a major price movement or event is imminent, and traders want massive exposure to certain risks and rewards.

To identify significant movements, traders can use volume, open interest, and implied volatility effectively to navigate the options market:

• Volume: One of the main signs of unusual option activity is when specific options contracts trade at volumes far exceeding the historical averages. The volume levels that are reported each day on an options chain are where traders can see specific strike prices and which saw unusual options activity for that day.
• Open Interest: This is a representation of the total number of active contacts that have not been exercised or sold on an options chain. If there’s a substantial increase in open interest for specific options contracts compared to historical averages, you’re witnessing unusual options activity.
• Implied Volatility: If implied volatility is higher than usual, it could suggest increased market uncertainty or upcoming events that could significantly impact the underlying asset’s price. This unusual options activity can help traders keep ahead of new market developments that could go against them.

Advanced Tips for Reading an Options Chain

For more advanced strategy whole reading options chains, check out these advanced tips to take your trading game to the next level. We’ll be delving into more involved trading concepts like examining high and low implied volatility levels, implied volatility skews, and studying earnings reports’ impact on options’ pricing.

High and Low IV Rank/Percentile

Professional traders use IV rank and IV percentile for finding the best opportunities and for correctly timing trades. Doing so allows traders to compare the current implied volatility to its historical volatility levels. These act as signals that options are cheaper or more expensive. Performing this comparison helps traders time their moves well—they can buy options when volatility is expected to rise and sell options when volatility is expected to wane. Using IV rank and percentage allows them to gauge market sentiment to correctly position themselves in the best possible place within the market.

• High IV Rank/Percentile: The volatility level is high compared to historical data. This suggests to traders that they should be using strategies that profit from volatility decline if the market takes a downturn. In this case, traders can profit from moves like cash-secured puts or covered calls.
• Low IV Rank/Percentile: The volatility level is low compared to historical data. This could be good timing for buying options if there’s a significant price movement expected around an event like earnings announcements.

Implied Volatility Skews

Skews in IV refers to the difference in implied volatility levels across different strike prices of an option. Options with certain strike prices will have higher IV than others which results in a disparity in options prices based on the strike price instead of the time to expiration. Identifying skew in implied volatility will look like a smirk or smile shape on a volatility graph.

How Do Implied Volatility Skews Affect Contract Pricing?

Options with higher implied volatility will have higher premiums when there’s a significant volatility skew. You usually see this with further out-of-the-money puts. On the other hand, options with lower implied volatility will have lower premiums when there’s a considerable skew in volatility. You see this a lot with at-the-money calls. All told, it’s more expensive to purchase options that have a higher level of IV.

Earnings Reports’ Impact on Options Pricing

Around the time of an earnings report release, stocks may meet or miss expectations. These anticipations of movement usually result in option increasing in prices as a movement up or down is likely to take place. Options tend to be more expensive leading up to earnings and this can have a profound effect on the risk and reward balances of your trades and investments.

Use These Strategies after Viewing the Options Chain

• Selling Covered Calls: Consider executing this trade by navigating a list of available call options on a stock you already own. Once you’ve entered the strike price and expiration date you’d like, sell the call options against your existing shares. This will create an obligation to sell your stock at the chosen strike price if it reaches that point before expiration. You will receive a premium upfront for selling these call options.
• Buying Protective Puts: Consider buying a put option while holding a long position in an underlying asset. Select a put option on a stock you already own. It’s insurance against considerable price drops in the stop price. Not only can traders or investors use this strategy to protect themselves against potential losses if the underlying asset’s price falls, but they can still benefit from any upside potential.
• Using Spreads: Use options chains to execute vertical spreads where traders simultaneously buy and sell a call or put option of the same underlying asset with different strike prices with the same expiration date.

Common Mistakes to Avoid When Analyzing an Options Chain

Analyzing an options chain can be done correctly, but there are some common mistakes that newer traders or investors can fall into if they aren’t careful. Read your options chain correctly to make the best possible trade decisions for your portfolio, and do your best to avoid these blunders that so many other newcomers have fallen into.

• Misinterpreting Bid-Ask Spreads: If you want the best trading outcome, you’ll want to choose options contracts with narrow bid-ask spreads. When the bid-ask spreads are narrow, it can indicate high demand and market efficiency. In other words, these options are much more liquid. Don’t invest in options contracts with wider bid-ask spreads because they’ll be more difficult to buy or sell efficiently.
• Trading Illiquid Options: Liquid options are the ones you want to trade because they can be bought and sold quickly and efficiently. Liquid options have narrow bid-ask spreads and their trading volume is higher compared to other contracts.
• Ignoring Implied Volatility: IV has a profound effect on the pricing of options contracts, and ignoring it can have consequences on the way you trade. When implied volatility is high, this can lead to higher options prices. You’ll want to consider buying options when the IV is low and selling when the IV is high to create a profit.
• Ignoring the Impact of Theta Decay on Longer-Term Trades: Not considering how the passage of time will erode an options contract’s value can lead to significant losses, especially when the trader is holding a lot of positions closer to the expiration date. Losses could still be incurred when the underlying asset price moves favorably.
• Buying OTM Options Without a Clear Strategy: Traders who purchase options contracts where the strike price is very different from the current market price of the underlying asset might experience a low probability of success using this move because the option is likely to expire as worthless. It could result in the trader losing their entire premium if the price doesn’t move significantly in the desired direction.

Understand the Options Chain Inside and Out

Mastering an options chain can significantly improve decision-making. You have access to the important elements of options contracts like bid/ask prices, open interest, implied volatility, volume, strike prices, and expiration dates that can be used to pinpoint liquid options that are separated into call and put columns. With all of their factors at your fingertips, you can nimbly navigate the options market in a way where you maximize profit and minimize losses.

Spot unusual options activity by looking through an options chain to view the information on volume, implied volatility, and open interest. Use the Greeks to evaluate and assess the risk factors at play with each option contract. Feel free to practice using real-time options chains on your broker platform of choice.
