Filing Risk-Factor Changes: A Reproducible Research Method

Direct Answer

Comparing risk factors between 10-K filings can reveal how a company describes changing exposures, but textual change is not automatically economic change. A reproducible analysis should align reporting periods, preserve the original wording, classify additions and removals, and verify interpretations against the full filing.

Key Takeaways

• AI is a research aid, not a guarantee of investment performance.
• Verify material financial claims against current primary sources.
• Record source dates, data periods, assumptions, and limitations.

Collect comparable filings

Use the same issuer and comparable reporting periods. Record accession numbers, filing dates, fiscal periods, and whether a filing was amended.

Normalise without erasing meaning

Remove formatting noise while preserving headings, lists, qualifiers, and paragraph boundaries. Do not treat a changed sentence as meaningful without reading its context.

Classify changes

Separate new risks, removed risks, expanded language, narrowed language, reordered sections, and wording changes that do not alter substance.

Validate against primary evidence

Compare the risk-factor change with the business, financial statements, earnings commentary, and other disclosures. Publish examples and limitations with the method.
