Company signal research method

Q: What should the research method define before analysis?

Define the question, population, sample, observation period, inclusion rules, exclusions, and outcome before inspecting patterns.

Q: How should personal data be protected?

Use only data needed for the question, limit access and retention, and aggregate or suppress groups that could identify a person.

Q: Can an observed pattern become a hiring rule?

No. Report uncertainty and plausible alternatives, and keep observation separate from recommendation or prediction.

Q: When should the method be reviewed again?

Review it when the source, sample, definition, product behavior, or observation window changes, and keep the review date visible.

See the proposed inputs, sampling rules, exclusions, privacy safeguards, and reporting limits for company signal research method. No aggregate claim is published until the required evidence and review threshold is met.

Methodology explains a preparation signal; it does not turn the result into a hiring prediction.

Company signals should point back to a filing or dated event

Use SEC EDGAR and Open DART for source-linked disclosures. Keep hiring activity, financial facts, funding events, and employee sentiment as separate evidence types.

Which company changes are supported by an official filing, and which are only indirect signals?

Verified public facts

2026-08-27

SEC data APIs provide company submission history and extracted XBRL data as JSON without authentication or API keys.

How to use it: Linking a U.S. public company profile to its filing history and source documents.
What this data cannot establish: That every company has SEC filings or that a filing confirms workplace quality.

2026-08-27

SEC Company Facts returns a filer’s standardized XBRL concepts in one JSON response; comparisons still need aligned periods, units, and filing context.

How to use it: Source-linked financial trend tables for entities and concepts with compatible reporting context.
What this data cannot establish: A valuation, runway, funding round, or operating health score without further evidence.

2026-08-27

Open DART makes DART filing documents available as XML and exposes major disclosures, ownership reports, securities filings, and periodic-report data through APIs.

How to use it: Linking a Korean disclosure subject to filing dates, report types, and original documents.
What this data cannot establish: A complete private-company profile or a prediction of future hiring.

2026-08-27

Open DART provides major accounts, full financial statements, source XBRL files, and major financial ratios for covered periodic reports.

How to use it: Source-linked Korean company financial tables with filing and amendment dates.
What this data cannot establish: That the regulator guarantees accuracy or completeness; Open DART explicitly assigns responsibility to the filer.

Synthetic company-signal example

Synthetic example for interpretation practice—not an observed Refresh result.

Scenario input: Example only: one legal entity reports a filing for fiscal 2025 while the brand operates several entities.
Calculation and interpretation: Attach the signal to the filing entity and fiscal period.
Decision this supports: Use it to form a question about that entity
Comparability limit: Do not assign it to the whole brand or compare it with a calendar-year figure.

Research protocol and unpublished result fields

How the data is handled

Resolve the entity
Store the regulator identifier, legal name, former names, market, and source jurisdiction before attaching a filing.
Keep the event trail
Attach the filing identifier, filed date, reporting period, amendment status, and original document to each signal.

Definitions that travel with the result

Filed fact: A value or event present in a regulator-hosted filing, identified by entity, filing, period, and source URL.
Indirect signal: An observation such as a job posting or review that may add context but does not establish a financial or legal fact.

Awaiting observed data

Required result fields

Entity identifier
A source-native identifier such as CIK or DART corp_code.
string · required
Entity name
The legal or filing name attached to the source identifier.
string · required
Filing identifier
The filing accession or receipt number used to open the source document.
string · required
Filing date
The date the regulator received or disseminated the filing.
date · required
Reporting period
The fiscal period represented by the filing or fact.
string · required
Source URL
The exact page or record used for the observation.
string · required
Category

string · required
Observed at
The date Refresh retrieved or checked the record.
date · required

Publish only when: Publish only after entity matching and amendment checks; link every event to its original filing.
Awaiting observed data: No company signal is shown until the entity and original source are verified.

What this data cannot establish

A filing can be accurate for its stated period and still be a poor proxy for current team conditions.
Absence of a filing is not proof that an event did not happen, especially for private companies or non-material events.

How to use it

Open the filing and read the reporting period before treating a signal as current.

Official data sources

EDGAR submissions and XBRL data APIsU.S. Securities and Exchange Commission2026-08-27
Coverage
Public filing history by filer and standardized XBRL facts from financial statements, delivered as JSON.
Boundary
Filing data describes what an entity disclosed. Periods, units, taxonomies, amendments, and entity identity must be reconciled before comparison.
Open DART corporate disclosure APIFinancial Supervisory Service2026-08-27
Coverage
DART filing documents, major disclosure items, ownership reports, and periodic-report financial data.
Boundary
Filers are responsible for their statements. Corrected filings can change values, and coverage depends on disclosure obligations and reporting format.
