Corrections

How Quantfil handles updates and corrections.

If a page contains a stale figure, misleading summary, broken filing link, or rights-related issue, Quantfil should make it easy to raise that concern and review it.

What we review

Correction requests can relate to stale numbers, broken links, misleading wording, unsupported claims, or problems in the way a company page summarizes the underlying filing. The site is informational, but that still requires care.

Because Quantfil relies on static generation and structured public data, some fixes involve the source data pipeline while others involve editorial copy. Both should be reviewed seriously.

What happens next

Requests are reviewed against the current source filing, the relevant static payload, and the live page output. If the issue is valid, the page should be corrected, updated, noindexed, or removed from the sitemap depending on what the evidence supports.

Rights and privacy matters should continue through the dedicated public intake pages when applicable.

How to report an issue

Use the public channels that match the problem

Figures or wording

If a guide or company page contains a stale figure, broken source link, or misleading summary, report it through the general contact path.

Rights and privacy issues

Rights, takedown, and privacy matters should use the dedicated intake paths so the issue reaches the right workflow quickly.

Possible page outcome

A valid issue can lead to a correction, a stronger clarification, a noindex decision, or removal from the sitemap if the page should not compete in search yet.

Material changes

September 10, 2026: reporting-period and comparison corrections

The data extractor now requires facts to match the selected filing accession, report end, duration, and supported units. Quarterly cash-flow figures are labeled year to date; missing values are not replaced with figures from a different quarter. Percentage comparisons from zero or negative baselines are omitted in favor of an explicit comparison note.

Automated positive and negative investment judgments were removed from company reference pages. Those pages provide reported data and direct sources, not a claim of editorial review.

September 10, 2026: case-study scope and teaching examples

The NVIDIA and Tesla case-study pages were replaced with fixed-period notebooks containing source tables and reproducible calculations. NVIDIA's notebook now explicitly covers FY2025 rather than claiming to describe the latest filing. The Meta notebook covers FY2024. General guides now distinguish hypothetical worked exercises from actual company disclosures.

Read the maintained notebooks or review the current source methodology.
