Price Movement Indicator: Market Maker Move

August 28, 2023 Advanced
Is the market pricing in a greater-than-typical move in a stock? Check the Market Maker Move™ indicator on the thinkorswim® platform. It can help inform your trading decisions.

When trading short-term fluctuations, it can be difficult to profit from a stock or option that doesn't move. But an unexpected spike in implied volatility (IV)1 can also potentially wreak havoc on a portfolio or trading strategy. Traders can attempt to guard against this—and potentially use it to their advantage—by monitoring the Market Maker Move™ (MMM) indicator on the thinkorswim® platform.

What is the Market Maker Move?

The Market Maker Move (MMM) uses some of the same inputs that market makers do, such as stock price, volatility differential, and time to expiration. A proprietary calculation then reverse-engineers the options pricing model based on assumptions about IV, creating an estimate of potential daily price movement.

Note that the MMM value does not guarantee a stock will move by a certain magnitude, nor does it indicate in which direction a move might occur. It only means the options market has priced in an expected move—up or down—over and above that of a typical trading day.

Let's look at an example. Say XYZ is trading at $100 and has an MMM of ±10. This tells the trader the options market has priced in a $10 move, whether as low as $90 or as high as $110, in light of an upcoming event like earnings. Of course, there are no guarantees. The actual move could be more or less, up or down, or there could be no reaction at all.

What if there isn't a MMM value?

In many instances, there's no MMM value present. It shows up only when "excess volatility" is detected. Typically, that means the IV in the current-week options expiration is higher than that of the next expiration date.

If there's currently a MMM, you'll see it on thinkorswim under the Trade tab > All Products. The MMM is shown on the same line as the symbol box, to the right of the bid and ask.

If MMM isn't showing up on the screen, it means the options market isn't pricing in any excess volatility. In normal markets, IV is lower in the front-month options contract than it is in deferred months. When the market is pricing in a potentially outsize move, such as right before an earnings release or other company announcement, front-month IV might be higher. That's when you'll see the MMM displayed as shown in the image below.

The image above shows a stock trading at $216.88 with an MMM of ±16.74. This tells a trader the options market has priced in a move to as low as $200.14 and as high as $233.62.

The MMM can be a powerful tool for traders during events like:

  • Earnings season, especially when holding shares of a company that's about to report
  • Pending company news, such as a new product release, potential merger/acquisition talks, or legal/regulatory action

How to use the MMM for earnings

When trading around earnings, there are some strategies that can be used with the help of the MMM:

  • Risk budgeting. Suppose you have an existing position going into earnings. Checking the MMM might be a good way to decide if it's worth the risk to hold through the event. For example, if your stock is trading at $216 and there's a MMM of ±5.4, you might be comfortable with an event risk of 2.5%. The image above, though, shows MMM is implying a potential 7.7% move. Whether you want to hold in this situation depends on your overall risk tolerance. You might decide that holding this position doesn't work for you if a risk event does materialize. 
  • Picking points. When reviewing your chart and trying to decide your entry or exit point, the MMM might add a level of possible validation to your entry point, profit target, or stop order level. Remember, though, if a stop order is triggered, it competes with other market orders. 
  • Choosing options strikes. Some option traders might use an iron condor2 in an attempt to capitalize on the expected collapse of IV that often comes after the market's initial reaction to earnings releases. In this instance, a trader might set strikes outside the MMM range. Or, if a trader wanted to put on a purely directional trade using a put or call, they could compare the at-the-money (ATM) options to the MMM. For example, if the ATM options are trading equal to or more than the MMM, they'd have a lower chance of profiting on the trade. But if the ATM is trading for less than the MMM—implying a potentially larger move than is being priced in—it might be a trade worth considering.

The MMM can be a helpful tool to inform a trader's strategy. However, it's important to remember it's a probabilistic measure that reflects the expectation of the potential magnitude (but not direction) of market movement. Even so, it can be a data point that helps traders make more informed trading decisions.

1The market's perception of the future volatility of the underlying security directly reflected in the options premium. Implied volatility is an annualized number expressed as a percentage (such as 25%), is forward-looking, and can change.

2A defined-risk short spread strategy constructed of a short put vertical and a short call vertical. You assume the underlying will stay within a certain range (between the strikes of the short options). The goal: As time passes and/or volatility drops, the spreads can be bought back for less than the credit taken in or expire worthless, resulting in a profit. The risk is typically limited to the largest difference between the adjacent and long strikes minus the total credit received.
