Identifiers that outlive a ticker

One row for each of the 10,868 funds and stocks with a file here: ticker, name, asset type, the exchange it is listed on, its composite and share class FIGIs from OpenFIGI, its SEC CIK and, for a fund, its SEC series and class ids, in one file of 1.3 MB, and the same rows in /api/v1/identifiers.csv. A ticker can change, and a ticker given up can pass to another security. Key your records on the composite FIGI or, for a fund, its SEC class id, not on the ticker: neither changes with the ticker nor passes to another security. A CIK names the company or trust that files with the SEC, and several securities can share one. Of them, 10,773 have a FIGI, 9,849 a CIK and 5,444 a series id; a field is null where its source does not list the security yet. Each fund and stock file carries its row's values under identifiers.
