Master Index Data

The SEC/EDGAR website provides various indexes of all company filings for each year/qtr. We use the "master.idx" file to create the resources on this website. The master index contains the CIK, Company Name, Form Type, Date Filed, and Filename for each filing. The historical data is not a fixed archive and will on rare occasions add/modify/delete a file. For this reason, we provide the master.index files used in producing our data.

The master.idx files for 1993-2020 were downloaded on 1/15/2021. The 2021 files were downloaded on 1/9/2022.
