Start with expectations, not the good-news label
A strong economic release can be followed by a price fall, while a weak one can be followed by a rise. To interpret the mismatch, ask what was expected before the release, what new information appeared and which price you are observing. “Good news” describes neither the expectation benchmark nor the full set of reasons a price might change.
Keep two questions separate: how the release differed from a named forecast, and why an asset price moved over a specified window. The first can be a calculation. The second needs evidence about expectations, possible valuation channels and other information arriving at the same time.
Match the release to a named, time-stamped benchmark
A forecast comparison needs more than a number labelled consensus. Record who produced it, how forecasts were collected or combined when that information is available, and when the benchmark was observed. Match its reference period, series, units and seasonal adjustment to the release. A forecast recorded after publication is not a pre-release benchmark.
A surprise is relative to that comparison, not simply to the previous month's result. Revisions add another distinction: a new estimate for the current month and a changed estimate for an earlier month are different pieces of information. The nonfarm payrolls guide explains those jobs and release-vintage labels; the CPI guide covers inflation series, comparison periods and adjustment.
Research by Ben Bernanke and Kenneth Kuttner separates expected and unexpected policy changes when examining historical US equity reactions. It also notes that an unchanged policy decision can surprise if a change had been anticipated. The study concerns US monetary-policy events from 1989 to 2002, rather than a fixed response to every kind of news. [1]
One fictional release, two different surprises
Assume a fictional first release R1 reports a seasonally adjusted monthly increase of 180 thousand US total-nonfarm payroll jobs. Compare two alternative pre-release benchmark scenarios for that same series, month and estimate vintage. These invented scenarios do not report actual BLS data or two measured consensus forecasts.
| Alternative scenario | Pre-release forecast | Reported estimate in R1 | Release minus forecast |
|---|---|---|---|
| Benchmark A | +150 | +180 | 180 − 150 = +30 |
| Benchmark B | +200 | +180 | 180 − 200 = −20 |
The same reported increase is 30,000 jobs above Benchmark A and 20,000 below Benchmark B. Both comparisons still describe an increase of 180,000 jobs. Neither difference is a percentage, a probability or a prediction of an asset return. Here, reported or “actual” means the estimate in R1, not an error-free count.
The exercise shows why the benchmark belongs beside the release. It does not tell you which forecast best represents participants' expectations, how dispersed their views were, or whether any particular asset will rise or fall.
Company earnings: separate EPS, consensus and guidance
For a company release, earnings per share (EPS) expresses earnings on a per-share basis. It is not a dividend paid into an account. A reported EPS result, an analyst consensus and management guidance have different sources and roles, even when all three use a number labelled EPS.
| Item | What it represents | What to retain |
|---|---|---|
| Reported result | The company’s reported figure for a completed period | Fiscal period, release version and accounting basis |
| Analyst consensus | A provider’s aggregation of analysts’ forecasts | Provider, aggregation method if known, and snapshot before release |
| Company guidance | Management’s forward-looking outlook | Target period, measure, assumptions and publication date |
Match the fiscal quarter or year, currency per share, basic or diluted EPS, and accounting or adjustment definition. Do not silently compare GAAP EPS with an adjusted consensus. For US reporting, SEC staff guidance says non-GAAP per-share performance measures should be reconciled to GAAP EPS. Adjusted labels alone do not establish a common definition.
Suppose fictional Company A reports Q1 adjusted diluted EPS of 1.20 currency units (CU) per share. A fictional provider’s pre-release Q1 consensus was 1.00 CU per share on the same defined basis. The matched difference is +0.20 CU per share. It is neither a price return nor a dividend. The provider’s consensus does not measure every participant’s expectation.
At the same announcement, management might give Q2 guidance of 0.90–1.10 CU per share on that basis. That future range is not Q1’s result or a Q2 analyst consensus. Without an earlier, comparable Q2 outlook, it does not establish a guidance cut. All these figures are invented; none determines the share-price reaction.
A historical Microsoft release dated 29 October 2025 illustrates separately labelled GAAP and non-GAAP diluted EPS, reconciliation and forward-looking outlook. It is a reporting example, not a current company forecast or an observed consensus for this exercise.
Keep possible channels separate from the observed move
News can bear on more than one part of an equity valuation. Bernanke and Kuttner examine changes in expectations about dividends, rates and excess returns to help interpret their historical policy-event results. Their decomposition does not supply a universal set of effects or a coefficient you can apply to the next release. [1]
- Expected cash flows
- Does the new information change expectations about future company earnings or distributions?
- Rates used in valuation
- Does it change expectations about future rates and the discounting of future cash flows?
- Required risk compensation
- Does it change the extra return investors require for bearing uncertainty?
- Observed price window
- Which asset, price measure and start/end observations are being compared, and what else happened in that interval?
Those questions can point to competing explanations. A favorable assessment of activity does not, on its own, settle the rate or risk-compensation channels. Nor does the final price change reveal each channel's contribution. Describing a move after a release establishes timing; attributing the entire move to that release requires more evidence.
Treat “buy the rumor, sell the news” as a possibility, not a rule
The maxim is a shorthand for a possible pattern: expectations build before an announcement, and the eventual news does not sustain the earlier price. It is not a test that identifies which rumor is credible, whether a price has moved too far or when a reversal will occur.
Likewise, saying that news was “priced in” is a claim about expectations already reflected in a price. One headline cannot establish that every relevant detail was anticipated. Identify what was expected, by whom or through which benchmark, and at what time. Leave the extent of anticipation uncertain when the evidence cannot establish it.
Build a short matched-news record
Use a record to keep the numerical comparison and the explanation of the price move from replacing each other. An empty field is useful information: it shows which part of the interpretation is still unsupported.
| Record | What to write down | What it cannot establish alone |
|---|---|---|
| Prior benchmark | Publisher, aggregation method if known, forecast vintage and observation time before release. | That every participant held the same expectation. |
| Release | Source, reference period, series, units, adjustment and release version. | That an initial estimate is permanently final. |
| Matched difference | Release minus that benchmark, retaining the original units. | A price return, causal effect or probability. |
| Possible channels | Separate cash-flow, rate and risk-compensation hypotheses and their evidence. | The size or net sign of their effects. |
| Observed move | Asset, price or quote definition, start/end times, and other information in the window. | That one announcement caused the entire change. |
For policy-related news, the FedWatch reading guide explains why a futures-based meeting estimate, a participant projection and an event-contract price need different labels. A contract also has its own question, source, deadline and payout rules. Understanding a release does not establish that such a contract exists or that you are eligible to use it.
A correct interpretation can still lead to a losing position: the entry price, actual fill, costs and contract outcome remain separate. This record organizes information; it has not been shown here to predict prices, improve returns or recover losses.
Common questions
Why can good news be followed by a price fall?
The news label leaves out the prior benchmark and possible valuation channels. A favorable release may fall short of an expectation or be accompanied by other information. A fall after the release does not, by itself, identify the explanation.
Does a strong result mean the market expected too little?
No. Compare the result with a named, time-stamped forecast for the same measure. In the fictional example, +180 thousand jobs exceeds a +150 benchmark but misses a +200 benchmark. Neither scenario measures everyone's expectations.
Can an unchanged policy decision be a surprise?
Yes. No change can differ from an anticipated change. That distinction appears in the historical monetary-policy research cited here; it does not provide the expectation or likely reaction for a current meeting.
Can a headline show that news was fully priced in?
No. You need evidence about the expectations and price observations being compared. The phrase does not certify that every detail was already anticipated or rule out other influences on the move.
Does interpreting news correctly guarantee a profitable contract?
No. A release comparison is different from a contract's rules, entry price, fills, fees and outcome. Real-money positions can lose money; understanding the news is not a reliable income source or a way to recover earlier losses.

Sources and scope
The 2004 Bernanke–Kuttner study concerns US monetary-policy events from 1989–2002 and supports the expected/unexpected distinction and discussion of valuation channels. It does not establish a universal response coefficient. The source was consulted in the 18–19 October 2026 evidence window. All payroll numbers and benchmark scenarios here are fictional. No current forecast, market move or trading performance is reported.
The added company-earnings comparison uses SEC reporting explanations and Microsoft’s historical 29 October 2025 release; source texts were checked on 20 October 2026. The EPS figures and provider snapshot in the example are fictional, not a current company forecast or observed consensus.
