Corrections

Our position

We recompute public data automatically on every trading day, across thousands of companies. At that scale, we will not claim to be error-free. Instead we commit to three things.

• We fix it — confirmed errors are corrected without delay.
• We fix the cause — not just the page in question, but every other company affected by the same cause.
• We prevent recurrence — if a rule was at fault, an automated test is added so the same error cannot return on a later build.

What to report

• A metric that disagrees with the filing or market data (P/E, P/B, market cap, financial figures)
• A sector or sub-sector classification that doesn't match the actual business
• Statements about a company or its results that are factually wrong
• Filing links that are wrong or broken
• Display problems or pages that don't work

Please include the company name or ticker, which item is wrong and how, and where possible a source for the correct value (filing title or link). That makes verification much faster.

How to report

By email — [email protected] (adding [Correction] to the subject line gets it looked at first).

No sign-up or form is required. We do not ask for personal details, and we store nothing beyond the email address needed to reply.

Process and timeframe

• Acknowledgement — within three business days.
• Verification — we check the original filing or market data to establish whether there is an error.
• Correction — confirmed errors are applied on the next update build. High-impact cases such as wrong figures are recomputed and republished immediately.
• Root cause — we determine whether it was a data issue or a rule issue. Rule issues are reapplied across every company, with a regression test added.
• Reply — we tell you what we found and what changed.

Where the source data itself is wrong or not yet updated, we do not silently substitute our own value. We say so in our reply, and the correction flows through automatically once the source is fixed.

How corrections are marked

• Figures are corrected by overwrite on update; each page shows its price as-of date and last updated date.
• When wording or interpretation changes, the page's last-updated date changes with it.
• Rule-level errors affecting many companies are published in the log below.

Correction log

Significant corrections that affected multiple companies.

• 2026-07 · Valuation label wrong for below-book companies — companies trading under book value (P/B below 1) were escalated to “overvalued” by a sector-average adjustment. We added an exception to the rule, recomputed every company, and added an automated test for this case. Affected: 27 companies
• 2026-07 · Sector misclassification — a partial match on company names placed some companies in the wrong sector (for example, an aerospace company whose name ends in “…space” classified under payments). Name matching was changed to exact matching, companies were reclassified, and 30 regression tests were added. Affected: 36 companies
• 2026-07 · List and detail pages disagreed — the same company could show “overvalued” in the list and “undervalued” on its detail page. The displayed label was unified to a single source, and a check now blocks deployment if the two diverge.
• 2026-07 · Forward P/E overstated for fast-growing earnings — for companies whose profits rose sharply, this year's earnings were projected too conservatively, making forward P/E look higher than it should. The projection procedure was changed to follow quarterly trends consistently, and a consistency check across companies in the same industry cycle was added.
