Where our stock data comes from, and how it is checked
Every figure traces back to one of three places: what the company filed, what the market priced, or what a public agency published. No number is typed in by hand and none is invented by a model.

Everything on a company page traces back to one of three places: what the company filed, what the market priced, or what a public agency published. No number is written by hand and none is invented by a model.


Company fundamentals
Revenue, margins, balance sheet, cash flow and share counts come from companies' own regulatory filings. That is the primary record, it is what auditors signed, and it is what everyone else derives their figures from anyway.
Guidance (what a company tells investors to expect) is lifted from the earnings releases filed alongside results, so what a company promised is quoted rather than paraphrased. Earnings call material comes from what companies publish openly on their own investor relations pages. Where a company puts its call behind a registration wall we leave it alone, which is why that section sits empty for a few companies.
Prices
Prices refresh through the US trading day rather than streaming, and there is a lag, always. If you need a price accurate to this second, use your broker. This is a research tool and it is not trying to be a terminal.
World events and macro
The event map is assembled from public agency feeds: geological surveys for earthquakes, meteorological agencies for storms, satellite fire detection, public health bodies, humanitarian reporting, and the published sanctions lists of the US, EU, UK and UN. Macro releases come from the official statistical sources that publish them.
These are worth citing by name. Public agencies publish this data precisely so it gets used, and saying where it came from lets you go and check.
Checks
The data we take in runs through automated quality checks on a daily cycle. They look for the specific ways this kind of data goes wrong: a fundamental that moved implausibly between filings, a price that has stopped updating, a corporate action (a split, say, or a buyback) that changed a share count without a matching filing, a figure that arrived in the wrong unit.
What checks can and cannot do
These catch breakage. They cannot certify that every figure is correct, and we are not going to claim otherwise. Anything material you are relying on is worth confirming against the filing itself, which is public and which we would rather you read than take our word for.
When something is wrong
Tell us. There is no cost to us in a corrected number and a real one in a wrong number that stays up. Corrections that affect scoring show up the next time scores are recomputed.
What we deliberately do not ship
Returnolio is not an intraday product. No streaming quotes, no one-minute bars, no order routing, nothing optimised for short-term timing. See What Returnolio is not.
