Options Implied Move - What Is It?
During Earnings Season: Understanding Options Implied Move
Market participants closely watch a critical metric during earnings season: the "options implied move" or "expected move." This market-derived forecast helps traders and investors prepare for potential price swings following earnings reports (ERs). While many factors influence stock prices, understanding the implied move can provide valuable context for risk management and trading decisions.
Defining the Options Implied Move
The options implied move represents the market's collective expectation of how much a stock might move after an earnings announcement. This metric, derived from options prices and implied volatility, provides a probability-based estimate rather than a guaranteed outcome. For example, if Apple (AAPL) has an implied move of 4% before earnings, the options market suggests approximately a 68% probability (one standard deviation) that the stock will move within ±4% of its current price after the announcement.
How the Options Implied Move is Calculated
Traders can calculate the implied move using two primary methods:
The Straddle Method:
Identify the nearest-term (front month) at-the-money (ATM) options
Add the prices of the ATM call and ATM put
Multiply the sum by 0.85 (85%)
For example, if XYZ stock trades at $100, and the ATM call costs $3 while the ATM put costs $2:
Straddle value = $3 + $2 = $5
Implied move = $5 × 0.85 = $4.25 (or 4.25%)
The Straddle-Strangle Method:
Calculate the ATM straddle value
Add the first out-of-the-money (OTM) strangle value
Divide the total by 2
While these calculations were historically done manually, modern trading platforms now provide real-time implied move data. However, understanding the underlying math helps traders validate these values and adjust their strategies accordingly.

Using Implied Move for Binary Events
The implied move serves several practical purposes that align with developing a sustainable trading edge:
Risk Management:
Position sizing based on potential price swings
Setting appropriate stop-loss levels
Determining option strike prices for strategies
Strategy Selection:
Evaluating whether option premiums are expensive or cheap
Choosing between directional and non-directional trades
Assessing the risk/reward ratio of potential trades
Common Pitfalls:
Implied moves are estimates, not guarantees
Historical moves may differ significantly from implied moves
Volatility crush after earnings can impact option positions
Managing these challenges requires strong trading psychology and the ability to maintain emotional control during high-volatility events.
Beyond Binary Events
While the implied move is most commonly used for earnings announcements, traders also apply this concept to other significant events like:
FDA drug approvals
Major product launches
Merger and acquisition decisions
Federal Reserve announcements
However, the accuracy diminishes for longer time frames due to compounding effects of implied volatility changes and time decay. Understanding price action becomes increasingly important for longer-term trading decisions.
Conclusion
The options implied move provides valuable insight into market expectations before significant events. When combined with fundamental analysis, technical indicators, and sound risk management, this metric helps traders develop more comprehensive trading strategies. For those seeking to master these concepts, personalized mentorship can provide structured guidance in developing and implementing these strategies effectively. Understanding both its capabilities and limitations allows market participants to use this tool effectively while avoiding common pitfalls.
Those interested in deepening their understanding of options trading might benefit from exploring volume profile analysis as a complementary tool for market analysis.
