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.
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.
