Options trading can be a complex and often intimidating aspect of the financial markets, but with the right tools and strategies, it becomes more accessible. One such strategy involves tracking and analyzing option block trades. These large transactions can provide valuable insights into market sentiment and help traders identify unsupported and unusual options that may present opportunities or risks. In this blog post, we will explore how to use option block trades to spot these unique situations and make more informed trading decisions.
What Are Option Block Trades?
Definition of Option Block Trades
Option block trades are large, privately negotiated trades that are executed outside of the public order book. These trades typically involve significant amounts of capital and are conducted by institutional investors, hedge funds, or other market participants with substantial resources. The size of these trades makes them noteworthy, as they can signal the intentions of major market players.
Why Are Option Block Trades Important?
Option block trades are significant because they can reveal market sentiment and potential price movements. When large institutions execute these trades, it often indicates a strong conviction about the future direction of an underlying asset. By tracking these trades, individual investors can gain insights into market trends and identify potential opportunities.
How to Spot Unsupported and Unusual Options Using Block Trades
1. Monitor Unusually Large Option Trades
One of the first steps in spotting unsupported and unusual options is to monitor for unusually large trades. These are trades that significantly exceed the average trading volume for a particular option. When a block trade occurs at a size much larger than normal, it can indicate that a major player is taking a substantial position, which may be based on insider knowledge or a strong belief in an upcoming market move.
Example: Suppose you notice a block trade of 10,000 call options on a stock that usually sees a daily volume of 500 options. This could indicate that an institution is betting on a significant price increase in the stock.
2. Analyze the Trade Direction
Understanding the direction of the trade is crucial. Is the block trade a buy or a sell? If it’s a large buy order, the trader expects the underlying asset’s price to rise. Conversely, a large sell order may indicate bearish sentiment. By analyzing the direction of the trade, you can get a sense of market expectations and adjust your strategy accordingly.
Supported vs. Unsupported Trades:
Supported trades are those that align with the general market sentiment and price trends. For example, if a stock is in a strong uptrend and a large block of call options is purchased, this trade is supported by the prevailing trend. Unsupported trades, on the other hand, go against the trend. For instance, if a stock is declining, but a significant block of call options is bought, it may signal unusual activity or insider knowledge.
3. Look for Unusual Strike Prices and Expiration Dates
Another way to spot unusual options is by examining the strike prices and expiration dates of the block trades. If a trade involves a strike price far out of the money or an expiration date that is much further out or closer than usual, it could be a sign that the trader is expecting a significant move that isn’t reflected in the current market.
Example: A large block trade involving call options with a strike price 20% above the current stock price and an expiration date only a few weeks away might indicate that the trader expects a sharp increase in the stock price soon.
4. Compare Open Interest and Volume
Open interest refers to the total number of outstanding options contracts for a particular strike price and expiration date. By comparing the open interest with the trading volume, you can identify unusual activity. If the volume of a block trade significantly exceeds the open interest, it may indicate that a new position is being established, which could signal a significant upcoming move.
Example: If you see a block trade of 5,000 contracts in an option with an open interest of only 1,000, this suggests that new positions are being created, potentially signaling a major shift in sentiment.

Case Studies: Real-World Examples of Using Block Trades
Case Study 1: Spotting a Bullish Reversal
In early 2023, a large block trade of call options was executed on a tech stock that had been in a prolonged downtrend. The strike price was significantly above the current market price, and the expiration date was only a few weeks away. Despite the bearish trend, the size of the trade and the unusual strike price caught the attention of options traders. Within days, positive earnings news was released, and the stock surged, validating the block trade’s bullish stance.
Case Study 2: Identifying a Bearish Trend
In another instance, a significant block trade of put options was observed on a retail stock that had been performing well. The trade involved a strike price below the current market price and an expiration date several months out. While the trade seemed unsupported at the time, the stock later experienced a sharp decline due to disappointing earnings, and the block trade proved prescient.
Risks and Considerations
1. False Signals
Not all block trades will lead to significant market moves. Sometimes, large trades can be part of a hedging strategy or other complex financial maneuvers that don’t necessarily reflect a directional bet on the underlying asset. It’s essential to use block trades as just one tool in your trading strategy, alongside other forms of analysis.
2. Liquidity Concerns
Block trades can impact liquidity, especially in less liquid options. Large trades can lead to significant price movements, which may affect your ability to enter or exit a position at a favorable price. Be mindful of liquidity when trading options influenced by block trades.
3. Timing Considerations
Block trades often involve sophisticated investors with access to more information than retail traders. While tracking these trades can provide valuable insights, it’s essential to be cautious about timing. The effects of a block trade may not be immediate, and patience is often required.
Conclusion
Option block trades can be a powerful tool for spotting unsupported and unusual options that may present trading opportunities. By monitoring large trades, analyzing the direction and strike prices, and comparing open interest with volume, traders can gain valuable insights into market sentiment and potential price movements. However, it’s crucial to use this strategy in conjunction with other forms of analysis and be mindful of the risks involved. With the right approach, tracking option block trades can enhance your trading strategy and help you make more informed decisions in the options market.
