Correctiebeleid

Data corrections. Figures on this site come from automated pipelines. When a source revises a value, the next scheduled refresh overwrites ours and the as-of date updates — quotes hourly, fund metadata and analytics daily, full holdings weekly. Systematic errors (a wrong formula, a mislabeled unit) are treated as bugs: fixed in code, recomputed across every affected fund, and noted in the project changelog.

Editorial corrections. In-house data briefs are regenerated at least daily from current figures; a brief based on later-revised data is superseded automatically by the next run. Aggregated headlines belong to their publishers — factual issues in an article should go to the original outlet, which every item links to.

Reporting an error. Use Contact with the page URL and what looks wrong. Confirmed errors are corrected with the next deploy or pipeline run, and material methodology changes are documented on the Methodology page.
