How we cover markets
Our market coverage is produced by an automated pipeline. This page explains what it tracks, how each article is made and checked, where the numbers come from, and how to get something corrected. Last updated .
What we track
We follow a fixed list of instruments — the S&P 500, the FTSE 100, India's Nifty 50 and the DAX — and, separately, the largest cryptocurrencies by market value. The list is maintained by hand and every instrument in it is listed on our markets page. We do not cover every instrument that moves; we cover the ones we track.
Tracking an instrument is not the same as reporting on it. We publish a report only where we can verify what lay behind a move, which today means US-listed companies, whose disclosures are public and current through the SEC. Instruments listed elsewhere are tracked, priced and listed in our daily round-up, and we will widen the reporting as sources for those markets are added.
When a move becomes an article
A price move alone is not a story. A move of 2% or more in a share, ETF or index — 5% or more in a cryptocurrency — starts an investigation, not an article.
We publish only when we can identify a verified reason for the move, supported by at least two independent sources, at least one of them primary: a company announcement, a regulatory filing, an exchange notice or a central bank statement. Where no reason can be verified, the move appears in our daily round-up and gets no article of its own.
Moves are measured close to close in the currency the instrument trades in. We suppress moves caused by corporate actions — ex-dividend dates, share splits and consolidations — and moves in instruments too thinly traded for a price change to mean anything.
Cryptocurrencies are covered differently
Crypto markets never close and there is no closing price, so the daily crypto report measures each move over the 24 hours between one reading and the next, at the same time every day, and says in the piece which window it used. If a reading is missed the window is longer and the report states the longer figure rather than calling it a day.
We cover the largest coins by market value and turnover, excluding stablecoins, and we report a move of 5% or more. Market capitalisation is the price we print multiplied by circulating supply, so the two figures in a row always agree with each other.
The crypto report says what moved, not why. For a listed company we can point at the company's own filing; there is no equivalent disclosure behind a token, and the sources that do cover crypto day to day are not ones we are willing to rest a causal claim on. So the report states the moves and the figures behind them, and every draft is checked for causal language before it is published — a sentence explaining why something rose is treated as an error, not as colour.
How each article is checked
Before an article is published, it must pass every one of these checks:
- Every figure in the text is re-derived from the stored price snapshot the article was written from. A number that does not match the snapshot blocks publication.
- At least two independent sources, each a live link, none of them our own site.
- No statement that one thing caused another without a source attached to that sentence.
- No recommendation language — no buy, sell, hold, price target or similar. We report; we do not advise.
- A check against recent articles, so we do not publish near-identical pieces.
Any failure stops publication. Articles carry a note saying whether a person reviewed them before they went out.
Where the data comes from
- Prices and reference data come from our licensed market-data provider, credited on each article. Prices are delayed and the delay is stated with the timestamp.
- Charts are provided by TradingView, which serves its own data. Some exchanges, including the London Stock Exchange, cannot be charted this way; those pages link to the chart instead of embedding it.
- Reasons for a move come from company announcements and filings, regulators and exchanges, central banks and statistics offices, and licensed news wires. Sources are linked in every article.
Prices can be restated by the source after publication. A price in an article is a record of what the data said at the timestamp shown, not a live quote.
What this coverage is not
It is not investment advice, and it is not a recommendation to buy or sell anything. We do not publish price targets, forecasts or ratings, and nothing here takes account of your circumstances. If you are making an investment decision, take independent advice.
Corrections
If something is wrong, tell us and we will fix it. Email info@gbafmag.com with the article link and what is wrong.
- A wrong figure or a wrong attribution is corrected as soon as we have confirmed it, and the article carries a dated correction note.
- An article that should not have been published is taken down, and the reason is recorded.
- If a move reverses after we publish, we add a dated update rather than quietly rewriting the piece.
Corrections and takedowns are the responsibility of the editor named on our contact page.
