Big Tech Earnings Ahead: How to Read the Options Market’s Expected Move
Option prices offer a useful benchmark for earnings uncertainty. Understanding how that benchmark works—and where it breaks down—can help you evaluate a trade before risking money.
A technology company delivers strong earnings. Revenue beats estimates. Management sounds confident. The stock rises.
And someone who bought calls before the announcement still loses money.
How does that happen?
The purchase price matters. Before an earnings announcement, options already reflect uncertainty about the report and the stock’s possible reaction. A favorable move may be too small to justify the premium paid.
That is why the options market’s expected move, also called the implied move, deserves attention.
It helps answer a practical question: How much movement is already reflected in option prices?
For investors following big technology companies, this provides a benchmark for evaluating earnings reactions, comparing potential trades, and understanding the price of protection.
What does “expected move” actually mean?
An expected move is an estimate of the magnitude of price movement implied by options over a specified period.
The period matters. An estimate for options expiring Friday covers the time remaining until Friday’s expiration. If earnings arrive Wednesday evening, that window also includes trading before the announcement and afterward.
It does not isolate the earnings reaction perfectly.
There is also no single universal calculation. A platform might use an at-the-money straddle, an adjustment to that straddle, or an implied-volatility model. Two services can therefore display different figures without either having a data error.
Always check the expiration, quote timestamp, and calculation method before comparing estimates.
A practical starting point: the at-the-money straddle
A straddle combines a call and a put with the same strike price and expiration date. For a quick earnings benchmark, traders often examine the strike closest to the stock’s current price.
Adding the two premiums gives a straightforward estimate of the movement being priced into that combination. Fidelity describes straddle prices as reflecting market participants’ expectations about movement before expiration.
Consider this hypothetical example, using invented prices rather than a live options chain:
| Item | Hypothetical value |
|---|---|
| Stock price | $200 |
| Earnings announcement | Wednesday after the close |
| Selected expiration | Friday, after earnings |
| Strike price | $200 |
| Call midpoint | $6.20 |
| Put midpoint | $5.80 |
| Combined straddle premium | $12.00 |
The simple calculation is:
Straddle-based move = $6.20 + $5.80 = $12
As a percentage of the share price:
$12 ÷ $200 × 100 = 6%
This produces a rough reference of $200 plus or minus $12, or $188 to $212.
Those boundaries also happen to be the expiration breakevens for this particular straddle if purchased for exactly $12 per share, before trading costs.
That connection is useful. It also creates a common misunderstanding.
An implied range is not a price fence
A $188–$212 reference does not mean the stock must stay inside those levels. It does not establish support at $188 or resistance at $212.
A sufficiently surprising announcement can produce a much larger move.
Nor does the simple straddle calculation automatically establish a 68% probability of finishing inside the range.
Some platforms display a model-based, one-standard-deviation range using an approximation such as:
Stock price × annualized implied volatility × √time in years
That is a different calculation from simply adding a call and a put. Attaching a probability to the result requires assumptions about how prices behave.
Earnings are particularly challenging because information arrives at a scheduled time and can cause an abrupt jump. Research on earnings-option pricing explicitly models that jump and distinguishes options-implied distributions from historical ones.
Treat an expected move as a pricing reference with a methodology behind it. Ask what the number measures before deciding what it means.
What happens to the hypothetical straddle?
Suppose you buy the $200 call and $200 put for a combined $12 per share.
For one standard, unadjusted equity-options combination covering 100 shares, the premium outlay is $1,200, excluding fees.
If held to expiration, the outcomes would look like this:
| Stock price at expiration | Combined option value per share | Profit or loss per combination* |
|---|---|---|
| $180 | $20 | +$800 |
| $188 | $12 | $0 |
| $194 | $6 | −$600 |
| $200 | $0 | −$1,200 |
| $206 | $6 | −$600 |
| $212 | $12 | $0 |
| $220 | $20 | +$800 |
Assumes purchase at exactly $12, a standard 100-share multiplier, and excludes commissions, fees, and exercise-related costs.
A move from $200 to $206 is a 3% gain in the stock. In this example, the long straddle still loses half its purchase price at expiration.
A trader who bought only the hypothetical call for $6.20 would have a different expiration breakeven: $206.20. Each position must be evaluated using its own entry price and payoff.
Why the morning after earnings can look different
The table describes expiration outcomes.
If you sell the options earlier, they may retain time value. Their prices will also reflect the stock’s new level, remaining uncertainty, and current market conditions.
This is where implied volatility crush enters the discussion.
Before earnings, traders pay for exposure to an unresolved announcement. Once the report arrives, some uncertainty disappears, and implied volatility often falls. Research documents this pattern in earnings-related options, although the size and timing vary.
Falling implied volatility can reduce purchased-option values, all else equal. A favorable stock move must be assessed alongside that repricing and the passage of time.
A stock moving beyond your straddle-based benchmark can be encouraging for a long-volatility position. Your actual result still depends on what you paid and when, and at what prices, you exit.
What option prices cannot tell you
They cannot reliably tell you direction. A large implied move reflects substantial priced uncertainty. The straddle calculation itself supplies no bullish or bearish forecast.
They cannot tell you whether strong earnings will satisfy investors. Revenue, margins, guidance, capital spending, and management commentary can all affect the reaction. The benchmark does not explain which detail will dominate.
They cannot guarantee that an option is cheap or expensive. A premium that looks high can precede an even larger surprise. A premium that looks modest can still be costly if little movement follows.
They cannot establish your personal trading edge. Observing the same expected move everyone else can see is a starting point for analysis. You still need a reason to believe a particular position offers an attractive balance of potential return and risk.
For big technology companies, useful research questions might include whether cloud growth supports spending plans, whether advertising margins are improving, or whether AI products are producing measurable revenue. These questions help develop scenarios; none makes the earnings reaction certain.
Compare history carefully
Historical earnings reactions can provide context, but the comparison needs a consistent measurement.
An overnight opening gap differs from a close-to-close return. An intraday high differs from Friday’s closing price.
If your implied estimate covers several days through expiration, comparing it only with the first after-hours jump mixes two different horizons.
A research worksheet can record:
- The pre-announcement closing price.
- The next session’s opening and closing prices.
- The closing price at the selected expiration.
- The largest recent earnings reactions.
- The implied estimate recorded before each announcement.
Use several observations and examine unusually large moves. A small historical sample can miss the event that matters most to a leveraged position.
Past reactions also occurred under different valuations, expectations, and market conditions. They provide context for a hypothesis rather than proof that today’s premium is mispriced.
How to use the number before placing a trade
Start by confirming the earnings date and whether the announcement occurs before the open or after the close. Then choose an expiration that actually includes the event.
Record the stock price and contemporaneous call and put quotes. Midpoints are useful for analysis, but an order may fill at a less favorable price. Wide bid–ask spreads can materially change the economics.
Next, calculate the position’s own breakevens and potential loss. An expected-move figure cannot replace a payoff analysis.
Finally, model several outcomes: a small reaction, a move near the benchmark, and a much larger surprise in either direction. Include an exit before expiration if that is your plan.
Options can also be used to hedge existing shares, although protection carries a cost. Fidelity discusses protective puts as one way investors can reduce downside exposure around an earnings announcement.
The decision should follow from the position you own, the risk you can carry, and the price available.
Before the next big technology report, put two numbers next to each other: the move you think is plausible and the move reflected in the options you are considering.
Then examine the evidence behind the difference.
That is where an expected-move estimate becomes useful: it gives your earnings thesis a price to contend with.
