The SEC filings index is split in quarterly files since 1993 (1993-QTR1, 1993-QTR2...). By using python-edgar and some scripting, you can easily rebuild a master index of all filings since 1993 by stitching quarterly index files together. The master index file can be then feed to a database, a pandas dataframe, stata, etc...
An index file is a csv-like (pipe | separated) file that contains the following information:
- Company name (eg.
TWITTER, INC) - Company CIK (eg.
0001418091) - Filling date (eg.
2013-10-03) - Filling type (eg.
S1) - Filling URL on EDGAR (
edgar/data/1418091/0001193125-13-390321.txt)
Once python-edgar is finished downloading index files, you can open an index file with csv.csvreader or pandas.read_csv to have the data programmatically usable. Remember that the delimiter character is |!
python-edgar can be used as a library called from another python script, or as a standalone script.
- Compliant: Follows fair acces guidelines established by the SEC at https://www.sec.gov/os/accessing-edgar-data
- Efficient: retrieve compressed archives instead of raw index file that are 10 times bigger
- Import as a library in your python project or run as a standalone script
- Python 3 only with 0 external dependencies (Python 3 only as of v3.0.0)
Install from pip in a virtualenv
pip install python-edgarCall the library
import edgar

You will need to wrap your code in main() function to be able to run it on Windows:
def main():
import edgar
edgar.download_index(".", 2020, skip_all_present_except_last=False)
if __name__ == '__main__':
main() I am using python 2 ...
Python 2 support has been dropped as of October 2019. See https://pythonclock.org.
python-edgar does only one thing and does it well: getting and cleaning uncompressed quarterly index files to your computer. Use command line tools, in the spirit of unix philosophy, to stitch these index files together and create our master index file.
In this example, we called python run.py without arguments. It'll download every quarterly index file since 1993.
python run.py -y 1993

$ du -h master.tsv
2.3G master.tsvNow you have this master index file. It's not sorted but that's easy to do (hint: Look into the sort command)
Now that we have downloaded the index files it becomes easy, with a bit of command line scripting, to quickly filter by company and extract URLs to the filings we want with grep . In the following example we grep by CIK (1000045), store the output in an intermediate text file, which we re-open with cat and grep again by form 10-K. Prefix the paths with https://www.sec.gov/Archives/ and you'll get the full URL.

Use with caution: q does not use indexes so running queries against the master index will be very slow since it's rather large. Sorting the master index or narrowing the data to a smaller subset will make search faster. Ultimately you want to load the master index file into a proper database that's able to handle the size.
Some queries you may want to try
q "SELECT COUNT(1) FROM 1999-QTR4.tsv"q -d"|" "SELECT * FROM master.tsv where c1 = 1418091 and c3 = '10-Q' order by c4"
