Some of the most important news about a company appears first in the company’s own publication: a Form 8-K, an ad hoc announcement, a public tender notice or a job posting. Coverage follows and summarizes. This page uses two documented cases to show what the source’s own wording contains and what a summary can drop. It then describes four explicitly hypothetical scenarios for typical roles, each with its limit.
If you are looking for a competitor analysis example in the sense of a template or a matrix, this page is about the step before that: where does the material that goes into the analysis come from? The answer argued here is that the advantage of reading the source lies less in speed than in wording. The source’s own document says who is speaking, what exactly is said, and what is explicitly left unchanged.
Two things this page does not claim. It does not claim a lead of hours or days, because none of the references opened for it documents one. What is documented is the order of events. And it does not claim that keyword alerts would have missed these cases. Any alert would have caught the coverage. The underlying idea is set out in the Source-First Manifesto.
Why market participants publish so much themselves first
Some publications are mandatory. That makes those channels dependable: when a defined event happens, a disclosure has to follow. Other publications are voluntary but still say something. Job postings are the best-known example.
Form 8-K in the US
A current report on Form 8-K exists so that investors do not have to wait for the next quarterly or annual report. According to the SEC’s Investor Bulletin “How to Read an 8-K” (opens in a new tab), companies must make most 8-K disclosures within four business days of the triggering event, and the public can find them on EDGAR. Several items are especially useful for anyone following competitors, suppliers or customers:
- Items 1.01 and 1.02: entering into, or terminating, a material definitive agreement. The bulletin’s own example is a significant customer ending a long-term supply agreement early.
- Item 2.05: restructuring plans with material charges, such as closing plants or laying off workers.
- Item 5.02: departures and appointments of directors and senior officers.
The bulletin notes that it is not a legal interpretation.
A second type of mandatory filing covers ownership. In a January 2025 litigation release (opens in a new tab), the SEC explains that beneficial ownership reporting exists to give investors information about accumulations by persons “who have the potential to change or influence control” of a company. The first case below turns on exactly this kind of filing.
Ad hoc announcements under Article 17 MAR in the EU
Listed issuers in the EU must disclose inside information that directly concerns them, under Article 17 of the Market Abuse Regulation (MAR). Germany’s financial regulator BaFin explains in its issuer guidelines on the conditions for ad hoc disclosure (opens in a new tab) (in German) that events coming “from outside” can also require disclosure, naming the receipt of a large order as an example. BaFin also states that periodic reporting cannot replace ad hoc disclosure. Inside information does not wait for the next quarterly report.
The route of publication is regulated too. According to BaFin, the announcement goes first to a bundle of media that distribute it across the EU, in practice through a distribution service. Publication on the issuer’s own website (opens in a new tab) may not happen before that distribution. Afterwards the announcement must stay on the website for at least five years, and BaFin recommends a section under investor relations.
For anyone following a listed company, this means the announcement appears first through the distribution service, while the investor relations page is where it is kept complete and permanent. Both are channels of the same source.
A note on the legal position: the EU Listing Act (Regulation (EU) 2024/2809) reforms Article 17 MAR as of 5 June 2026, mainly for protracted processes. BaFin says in the overview of its ad hoc guidance (opens in a new tab) that this guidance now applies only to a limited extent and will be revised. This page is not legal advice.
Public buyers: notices on TED
Public contracts above certain thresholds must be advertised across the EU. The platform is TED (Tenders Electronic Daily), which describes itself (opens in a new tab) as the online version of the Supplement to the Official Journal of the EU. More than 3,000 notices are published there every weekday, access is free, and registered users can turn search profiles into email alerts or RSS feeds.
What matters for observation is the type of notice. According to TED’s page on European public procurement (opens in a new tab), a competition notice announces a procedure, while a contract award notice announces the outcome, such as the suppliers who signed a contract with the public buyer. Planning notices are among the other types. The 2026 to 2027 thresholds listed there include EUR 140,000 for services and supplies bought by central government authorities and EUR 5,404,000 for public works.
Here the source is the public buyer, a specific contracting authority. TED is its channel.
Voluntary but revealing: job postings
Nobody has to publish job postings to inform investors. Research nonetheless shows that they say something about a company’s future. The evidence is summarized in its own section below.
Case 1: the Twitter stake appeared first in a regulatory filing
On 4 April 2022, Elon Musk filed a Schedule 13G on Twitter, Inc. with the SEC. The EDGAR filing detail (opens in a new tab) shows it as filed and accepted that day. The form itself (opens in a new tab) reports 73,486,938 shares, 9.2% of the common stock, and gives 14 March 2022 as the date of the event requiring the filing.
Coverage followed the same day and cited the filing. CBC News (opens in a new tab) wrote that Musk “was outed as owning almost 10 per cent of Twitter on Monday” and that “a filing showed” his holding. The Bloomberg report republished by Al Jazeera (opens in a new tab) said Twitter shares rose as much as 27% after the purchase “was revealed Monday in a regulatory filing”.
What the SEC later alleged
Almost three years later the SEC sued. According to its litigation release of 14 January 2025 (opens in a new tab), Musk should have filed by 24 March 2022. The SEC alleges that he bought more than $500 million of Twitter stock between 25 March and 1 April 2022 and underpaid by at least $150 million as a result. These are allegations in a complaint, not findings of a court (as of the release of 14 January 2025).
What the case shows, and what it does not
The case shows the order of events: first the mandatory filing of a specific person, then the reports. Reading the filing also shows details that rarely make a headline, such as the type of form. The Bloomberg report pointed out that this type of form often indicates the investor is not seeking to acquire control.
The case also shows the limit. Before 4 April there was nothing to read. If a mandatory filing comes late, which is what the SEC alleges here, even the closest attention to the source does not help. And news about someone this prominent would have reached anyone through an ordinary news alert.
Case 2: Siemens Energy discloses the Gamesa problems in its own words
On 22 June 2023 at 19:22 CEST, Siemens Energy AG published an ad hoc announcement under Article 17 MAR (opens in a new tab), distributed through EQS News. It said that a technical review at its subsidiary Siemens Gamesa suggested that reaching the targeted quality of certain onshore platforms would cost significantly more than assumed, “likely to be in excess of 1 bn Euro”. Siemens Energy withdrew its profit guidance for fiscal year 2023.
The next day CNBC (opens in a new tab) reported that the company had “announced late Thursday” the findings of the review, and that the shares fell more than 37% on Friday.
What the announcement said, including what stayed unchanged
The CNBC headline led with the share price. CNBC quoted the announcement as saying it was “too early to have an exact estimate of the potential financial impact”. But the announcement also named what was not withdrawn: “We maintain our revenue guidance for the Group as well as all our assumptions for Gas Services, Grid Technologies and Transformation of Industry.” The report did not carry that sentence.
For a customer, supplier or competitor of one of those businesses, that sentence is the signal. It says where nothing changes. A report explaining a share price collapse has little room for it.
The announcement also said further details would follow with the third-quarter results. The earnings release of 7 August 2023 (opens in a new tab) then reported charges at Siemens Gamesa totaling €2.2bn and an expected net loss of around €4.5bn for the fiscal year. Following the source gives you both, the first announcement and the later figures, in the company’s words and with a date.
What research says about job postings
Two studies link job postings to how companies later perform. A third shows that a strategic shift, in this case the adoption of AI, can be read from job postings.
Chen and Li, in the Review of Accounting Studies (2023) (opens in a new tab), measured how long vacancies at US public firms stay open, using the creation and deletion dates of job postings. Firms that fill low-skill vacancies quickly and take longer over high-skill ones show higher future profitability. The authors find that this information “is not incorporated timely in the capital markets”, as seen in pessimistic analyst forecasts.
In a study published in 2020, Lo, Koedijk, Gao and Hsu analyzed job postings by publicly listed companies in Taiwan, collected with a web crawler. Their result in the Pacific-Basin Finance Journal (opens in a new tab): “new job openings foreshadow a firm’s operating performance”.
Acemoglu, Autor, Hazell and Restrepo drew on the near-universe of US online vacancies from 2010 onwards in a 2020 NBER working paper (opens in a new tab). The peer-reviewed version appeared in 2022 in the Journal of Labor Economics (opens in a new tab); the details below follow the working paper’s abstract. Establishments whose tasks were exposed to AI posted rapidly growing numbers of AI-related vacancies between 2010 and 2018 and reduced hiring in non-AI positions. At the level of whole occupations or industries, the authors found no discernible relationship between AI exposure and employment or wage growth.
Harvard Business Review put the idea this way in 2026: many companies analyze earnings calls and press releases yet overlook “one of the clearest and most accessible signals of strategic intent” (opens in a new tab), the jobs their competitors are trying to fill.
What these studies measure matters: statistical relationships across many firms. None of them predicts what one particular company will do. A job posting is content; only interpretation in context turns it into a signal.
Hypothetical scenarios for typical roles
The following scenarios are invented. They describe no real companies and no results. Each rests on one of the documented mechanisms above.
Product marketing: competitors’ career pages
Suppose the product marketing team at a software vendor follows the career pages of three competitors. One of them advertises several roles for a new team that is to build a product line in an adjacent segment. The product has no name yet, so there is no keyword for an alert to match. The team checks whether its own positioning in that segment holds up.
What limits this is that a job posting shows an intention, not an announcement. Roles get withdrawn, and the studies above describe many firms, not this one competitor.
Strategy: key suppliers’ mandatory disclosures
Suppose a strategy team follows the 8-K filings and, for European issuers, the ad hoc announcements of its five most important listed suppliers. One supplier reports a restructuring under Item 2.05 or withdraws its guidance. The team reads the wording and works out which plants and divisions are affected, and which are explicitly not, before reacting to headlines. The Siemens Energy case shows why the second part matters.
This works only as long as the supplier is listed. A privately held supplier discloses none of this.
Sales: contracting authorities on TED
Suppose a vendor that sells to the public sector uses TED to follow the notices of specific contracting authorities rather than keywords alone. Planning notices show intended purchases. Contract award notices show which competitor won which contract with which buyer. The sales team prepares for the next round with that knowledge.
Only contracts above the EU thresholds, however, must appear on TED. Smaller contracts go through national portals or are not published at all.
Competitive intelligence: ownership filings
Suppose a competitive intelligence team follows the ownership filings on its main competitors. When a new large shareholder appears, the team reads the filing itself, including the form type and any stated purpose. From then on, that investor is one of the sources the team follows.
The Twitter case shows, however, that a filing can come late, and until it arrives there is nothing to read.
Where keyword monitoring still fits
The opposing view deserves a straight answer. You would have heard about both cases on this page through keyword alerts, because the press covered them widely. And if you want to know how people talk about a company, you need media monitoring or social listening anyway. There, what third parties say is exactly the point.
The difference lies elsewhere. A report selects; a mandatory disclosure is complete and has a sender who is accountable for it. Beyond the two cases, one assessment follows: the smaller and less known a market participant is, the less likely anyone reports on its disclosures at all. For a mid-sized supplier or a regional contracting authority, the source’s own publication is often the only one. How to choose such sources and decide which of their channels to follow is covered in Source-First in practice. How this relates to competitive and market intelligence is set out in Source-First in context.
Limits
Every example on this page rests on content that the sources made public themselves: mandatory filings, public notices, job postings. This is about reading public documents with an identifiable sender, not about covert information gathering.
Mandatory channels are dependable but narrow. They cover only what the law requires, and only for the companies it applies to. Voluntary channels such as career pages are broader but less certain in what they mean. A useful list of sources and channels combines both and knows, for each channel, what it is good for and what it is not.
The statements on MAR and US rules summarize BaFin’s issuer guidelines and SEC publications. They are not legal advice.
