Plain English
The idea
A source note connects a claim to the evidence behind it. It should tell the reader where the fact came from, when it was observed, and how it was used.
Without source notes, research history becomes fragile. The reader may remember the conclusion but lose the filing, data release, transcript, or assumption that supported it.
Good source notes are practical. They do not need to be academic footnotes. They need enough detail for the reader to find the evidence again and decide whether it still supports the claim.
A source note links a specific claim to the material that supports it. It records the document, publication date, relevant passage or table, measurement period and limitations. The note should distinguish what the source states from the interpretation added by the reader.
A link to a large website is rarely enough. Another person needs to be able to find the same information and understand why it bears on the claim, without reconstructing the whole search.
Worked Example
Turning a note into a later check
Suppose a report says working capital pressure is temporary. A useful source note points to the filing section, the date, the management explanation, and the assumption made by the reader.
When the next filing arrives, the reader can compare the new data with the old note. The question becomes specific: did receivables normalise, did inventory clear, and did management repeat or change the explanation?
That is how source notes become research history rather than storage.
In the hypothetical inventory example, the company filing reports a rise in stock held for sale. Management says the build is temporary. A source note records both, but labels them differently: the reported balance is a disclosed measurement, while the expected reversal is management's forward-looking explanation.
The later checkpoint is whether subsequent filings show stock being sold and cash being collected. If the company changes its reporting definition, that also belongs in the note. The original explanation should not be silently replaced by the latest one.
| Claim |
Working capital pressure is temporary |
| Source |
Quarterly filing and management discussion |
| Assumption |
Inventory clears over the next two quarters |
| Later check |
Compare next filing with the original claim |
Reading the result
A citation supports a claim, not everything around it
Suppose a filing confirms higher inventory but says nothing about customer demand. It supports the inventory statement; it does not establish that demand is strong. A separate inference connecting the two should be labelled and tested against other evidence.
The same principle applies to summaries produced by people or software. A fluent explanation may combine a disclosed fact, a management forecast and an analyst assumption. Tracing each part back to its basis prevents a reputable source from lending undeserved authority to claims it never made. Several websites repeating one original release are also not independent confirmation.
Limits and assumptions
Access and reporting limits remain visible
Documents can be amended, links can move and economic series can be revised. Retain enough publication and location information to distinguish the version originally used from later material. In US filings, an amendment can be identified by the form's /A suffix; other reporting systems have their own conventions.
A source can be authentic yet incomplete, selective or unsuitable for the question. Management has an informed but interested perspective; an old estimate may no longer describe the business. Recording those limits makes the note more useful. It does not turn the source into a guarantee or remove the need to reassess the claim.
Common Mistake
Saving links without saving meaning
A saved link can become useless if the reader does not know why it was saved. The meaning of the evidence needs to be captured beside the source.
The better habit is claim, source, date, assumption, and later check. That small structure makes research easier to audit.
The quality of a note is not measured by the number of links attached. One directly relevant table with a clear limitation can be more useful than many general pages that never support the central statement.
Self-check
Check your understanding
How should the inventory balance and management’s explanation be recorded?
As different kinds of information: a reported measurement and a forward-looking interpretation. Keeping that distinction makes the later review more precise.
Do several articles quoting the same release provide independent confirmation?
Not necessarily. They may share one underlying source. Trace the claim to its origin before treating repetition as corroboration.
What if a cited page cannot be accessed or no longer supports the claim?
Record the limitation and seek a specific accessible source. Do not present an unverified citation as evidence merely because its institution is reputable.
Strata Research context
Check the evidence behind a revision
Strata Research reports include sources and evidence limits. When comparing saved versions, return to the cited material and check whether the relevant information is new, revised or still uncertain.
