The most recent Daily List is available in two formats: view (HTML) and download (ASCII text file). The Daily List may be initially posted at 8:30 p.m. Eastern Time (ET) before each trading day, then once per hour from 9:00 p.m. ET until 6:00 p.m. ET the following day, or simply updated once per hour from 8:00 a.m. to 6:00 p.m. ET on each trading day depending on the file type. To have the most up-to-date information during the trading day, market data distributors should process each of the updated files for all Daily Lists.
CUSIP numbers are the property of the American Bankers Association (ABA) and are administered by Standard & Poor's. Since IEX neither owns nor controls CUSIP numbers, distributors cannot be authorized to receive the daily list or fundamental data files including CUSIP Data unless they have a license in place with CUSIP. Please note that IEX is not responsible for obtaining written approval from CUSIP prior to authorizing data distributors to externally redistribute CUSIP data; it is the responsibility of the data distributor to obtain such CUSIP permission for their downstream customers.
Participants who wish to access the CUSIP version of these files must provide their CUSIP license information when creating an account for the website. Access to download the CUSIP version will be granted only after IEX has verified licensing.
Note that all securities are represented using INET sybmology below, however IEX provides securities in SIAC/CQS symbology and CMS symbology in the details or download version of each record.
