The essentials in 30 seconds
- An earnings “beat” exceeds a chosen estimate; it does not promise a share-price rise.
- The outlook may matter more than the quarter that has just ended.
- Revenue, profit, margin and cash flow tell different parts of the story.
- Valuation, the prior price move and investor positioning also shape the reaction.
- Implied volatility can fall after the event. A bought option can lose value even when the share moves in a favourable direction.
The market compares results with expectations
“Good earnings” often means revenue or profit grew from last year. But a share price before the release can already reflect expectations of even stronger growth. The report changes the price only insofar as it changes that outlook.
The consensus is an aggregate of analyst estimates. It is a useful reference, not every investor’s expectation. A number above consensus is called a beat, yet some investors may have expected more.
“Priced in” means a belief has already influenced buying and selling decisions. There is no visible label showing one exact expectation embedded in the price. What matters is how the report alters the previous view of the company.
A strong past quarter, a weaker outlook
The company and all figures in this example are hypothetical. We follow one sequence to separate backward-looking results from forward-looking expectations.
Before the report
Last year’s quarterly earnings per share: €1.50. Current-quarter estimate: €1.80. Next-quarter estimate: €2.10.
In the report
Current earnings per share: €1.85, above last year and consensus. But management forecasts only €1.90 for the next quarter.
Possible reassessment
In this assumed scenario, the share drops from €100 to €96 as investors give more weight to the weaker outlook than to the small beat.
This is one possible reaction, not a price formula. The same figures could be judged differently in another setting.
Reported profit is about 23.3% above last year but only 2.8% above consensus. Guidance is about 9.5% below the previous next-quarter estimate. A positive headline and a negative price reaction can therefore coexist.
Guidance, margins and earnings quality
Guidance is management’s outlook for measures such as revenue, profit or margin, sometimes expressed as a range. Lower guidance can change assumptions about future cash flows.
A margin is the share of revenue left after a defined set of costs. Revenue can rise while margins narrow because of prices, product mix or expenses. Compare the same margin definition across periods.
Where profit comes from also matters. A one-off asset sale or tax effect may lift reported profit without strengthening the core business. Cash flow tracks cash movements and differs from accounting profit.
“Adjusted” earnings exclude certain items. In US reporting, GAAP and non-GAAP figures may differ. Meaningful comparisons need the same definition, period and adjustments.
Why the share price beforehand matters
A company can deliver good results while its shares are already valued for exceptional future growth. A merely solid quarter may add little positive information, while small doubts about future growth gain weight.
During the conference call after the release, management may discuss demand, costs or orders that add to the first headline. A share can initially rise and later fall without the reported numbers changing.
The wider market and investor positioning also matter. Profit taking, hedging and changing sentiment can contribute. “Sell the news” describes some outcomes, not a rule for every release.
The options link: right direction, lower premium
Before earnings, the size of the coming share move is uncertain. That event uncertainty can raise option premiums and implied volatility (IV), a volatility measure inferred from option prices rather than a direction forecast.
After the report, some uncertainty disappears. IV can fall, sometimes sharply; this is often called an IV crush. It does not happen by a fixed amount after every report. New uncertainty can keep IV high or push it higher.
Same hypothetical share move · bought put
A put with a €100 strike costs €6 per share before the report. With the share at €100, it has no intrinsic value. After the assumed fall to €96, its intrinsic value is €4. Assume its new option price is €5.
| Component | Before | After |
|---|---|---|
| Share price | €100 | €96 |
| Put intrinsic value | €0 | €4 |
| Time value | €6 | €1 |
| Option price | €6 | €5 |
Intrinsic value rises by €4, but time value drops by €5. The put price falls by €1 per share, or €100 per contract with an assumed 100-share multiplier, before fees.
A put’s intrinsic value is the positive difference between strike and share price. Time value is the rest of the option price. Falling IV and less remaining time can reduce it; this example does not attribute the full €5 time-value decline to IV alone.
How to read the reaction more carefully
Compare the same measure with the same prior estimate. Then examine guidance and its assumptions, followed by revenue, margin and cash flow. This gives the price move useful context.
For an option, ask another question: How much movement and uncertainty was already reflected in the premium? A share and its options respond to the same news but have different price drivers.
Our earnings calendar helps you see event dates; the date alone predicts neither a surprise nor a reaction.
Further detail: show assumptions and context
Example arithmetic: (1.85 / 1.50 − 1) × 100 ≈ 23.3%; (1.85 / 1.80 − 1) × 100 ≈ 2.8%; (1.90 / 2.10 − 1) × 100 ≈ −9.5%. Current earnings and guidance concern different quarters.
The option quotes are assumed observations, not a Black–Scholes result. Put intrinsic value = max(strike − share price, 0); time value = option price − intrinsic value. Here, (4 − 0) + (1 − 6) = −€1 per share. The decomposition does not calculate an isolated vega or exact IV effect.
Vega measures local sensitivity to IV. Delta, theta and other factors can change at the same time. Exact attribution requires a valuation model and consistent inputs.
