What is Expected Move?
Expected move is a statistical measure that estimates the potential price range of a stock by expiration, based on the current implied volatility of its options. It represents the one standard deviation move that the market expects, giving traders a 68% confidence interval for where the stock price might land.
This metric is derived from at-the-money (ATM) options prices and their implied volatility. When options traders price contracts, they're essentially making predictions about future volatility. The expected move translates this collective market wisdom into a concrete price range.
Understanding expected move is crucial for options traders, especially when trading around earnings announcements, economic events, or other catalysts that can cause significant price movements.
How to Use the Expected Move Chart
Enter Stock Symbol
Type in the ticker symbol of the stock you want to analyze (e.g., AAPL, TSLA, SPY). The tool works with any optionable stock.
Select Expiration Date
Choose the options expiration date you're interested in. The tool shows all available expiration dates with days remaining until expiration.
Analyze the Results
Review the expected move statistics including upper and lower bounds, implied volatility, and the visual chart showing volume distribution across strikes within the expected range.
Make Informed Decisions
Use the expected move range to inform your trading strategy. Sell options outside the range for premium collection, or buy options if you expect movement beyond the expected range.

Understanding Expected Move Calculations
The Formula
Expected Move = Stock Price × Implied Volatility × √(Days to Expiration / 365)
This formula calculates the one standard deviation move, which statistically means there's approximately a 68% probability that the stock will close within this range by expiration.
Implied Volatility (IV)
Implied volatility represents the market's expectation of future volatility. It's derived from options prices using pricing models like Black-Scholes. Higher IV indicates the market expects larger price swings, resulting in a wider expected move range.
Confidence Levels
- 68% (1σ):The standard expected move range shown by default in this tool
- 95% (2σ):Double the expected move for a wider confidence interval
- 99.7% (3σ):Triple the expected move, covering extreme scenarios
Practical Applications
Earnings Trades: Expected move is particularly useful before earnings announcements. Compare the expected move to historical earnings moves to gauge if options are pricing in a typical or unusual reaction.
Option Selling: Sell options with strikes outside the expected move range to collect premium with a statistical edge, as the market expects the stock to stay within the range.
Directional Trades: If you expect a move larger than the expected range, buying options can offer asymmetric risk/reward as you're betting against the market consensus.
Risk Management: Use expected move to size positions appropriately and set stop losses that account for normal volatility.
Frequently Asked Questions
What does expected move tell me?
Expected move tells you the price range where the market expects a stock to trade by a specific expiration date, based on current options pricing. It's a forward-looking measure derived from implied volatility, giving you insight into market expectations for future price movement.
How accurate is expected move?
Expected move is based on statistical probabilities. The one standard deviation range (68% confidence) means that historically, stocks close within this range about 68% of the time by expiration. However, it's not a guarantee—markets can and do move beyond expected ranges, especially during unexpected events.
When is expected move most useful?
Expected move is particularly valuable before earnings announcements, FDA decisions, economic data releases, or other binary events. It helps traders understand if options are pricing in a normal or elevated move, and can inform decisions about whether to buy or sell options around these events.
Why does expected move change?
Expected move changes as implied volatility changes. IV typically increases before known events (like earnings) as uncertainty rises, then decreases after the event (IV crush). Changes in the stock price and time decay also affect the expected move calculation.
Can I use this for any stock?
Yes, you can calculate expected move for any stock that has listed options. However, the calculation is most reliable for liquid stocks with active options markets, as these have more accurate implied volatility pricing. Thinly traded options may produce less reliable expected move estimates.
Is this tool completely free?
Yes, the Expected Move Chart tool is 100% free to use with no registration required. You get access to real-time options data, expected move calculations, and interactive charts at no cost.
