The most recent Daily List is available in two formats: view and download. The IEX-Listed Symbol Directory Daily List is initially generated and posted to the IEX website at 8:30 p.m. Eastern Time (ET) before each trading day, and then once per hour from 9 p.m. until 6 p.m. ET the following day. The IEX Corporate Actions, IEX Dividends, and IEX Next Day Ex-Date Daily Lists are generated and posted to the IEX website once per hour from 8:00 a.m. to 6:00 p.m. ET on each trading day.
If, under extraordinary circumstances, IEX must publish an ad-hoc change to any daily list, a new file will be posted to the website immediately and a notice will be disseminated.
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 IEX Account. Access to view or download the CUSIP version will be granted only after IEX has verified licensing. Please see the Appendix of the IEX Daily List Specification for step-by-step instructions. To view or download CUSIP data once authorized, first log in, then return to daily list of interest to either “View details” or “Download.”
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.
