EPC Expected Move

What is Expected Move?

Expected move represents the market's prediction of how far a stock's price might move by a specific date. It's derived from the current market price of options. It's a key statistical metric that traders use to estimate the potential range of a stock price over time.

The expected move is based on a one standard deviation range, meaning there is a 68% probability of the stock price ending within the expected move range. For example, a stock that has a price of $100 with an expected move of $5.72 in 30 days suggests there is a 68% probability of the stock price being within the range of $94.28 to $105.72 at the end of that period.

There are a couple of ways to calculate it. We use the following formula which is based on the current market price of at-the-money (ATM) straddles:

How do traders use Expected move in option trading?

There are a few ways traders use expected move:

• Understanding market sentiment: The expected move reflects the market's consensus on future volatility. Higher expected moves suggest the market anticipates significant price changes, perhaps due to an earnings report, while lower expected moves indicate calmer expectations.
• Setting Profit Targets and Stop-Loss Levels: The expected move provides a range within which the stock is likely to trade. Traders often use this to set profit targets or stop-loss levels. For example, if the expected move is $5.72 on a $100 stock, a trader might set a profit target at $105.72 and a stop-loss at $94.28.
• Evaluating strategies: Traders can assess whether a trade's potential move justifies their risk. For example, if a trader expects the stock to move beyond the expected range (e.g., more than $5.72), they might buy call or put options to profit from a larger price swing. If they think the stock will move less than the expected range, they might sell options to collect premium, betting that the stock stays within the predicted bounds.

Understanding the Chart

The Expected Move Chart displays both where a stock has been and where the market expects it to go. The blue line shows historical price movement up to today. From today forward, the chart shows future market expectations — green dotted line marking the upper expected move and red dotted line showing the lower expected move. These boundaries form a shaded area that represents the expected price range. Simply hover over any area of the chart to see its specific move at that date.

Each expiration date is marked by a green or red solid circle on the chart. The expected move widens as you look further out in time. At the top of the chart, you'll always see a dropdown menu for selecting an expiration date. You can change the selected expiration date to highlight on the chart the expected move for that expiration, which is indicated by a vertical red line.
