Workflow

Setup

Download index files, which contain the firm CIK, name, filing date, type, and URL of the filing.

edgar-analyzer download_index --user_agent "MyCompany [e-mail]" --output "./index"

Build a database of the previously download index files for more efficient queries.

edgar_analyzer build_database --inputdir "./index" --database "edgar-idx.sqlite3"

Download filings, only filings in the database but not downloaded yet will be downloaded. Download speed will be auto throttled as per SEC's fair use policy.

edgar-analyzer download_filings --user_agent "MyCompany [e-mail]" --output "./output" --database "edgar-idx.sqlite3" --file_type "8-K" -t 4

Example

Just a simple example of the job find_event_date. Based on the 1,491,368 8K filings (2004-2022), the table below shows the reporting lags (date of filing minus date of event).

We can find that most filings are filed on the same day as the event reported, and that over 99.99% of filings are filed within 4 calendar days (SEC requires 4 business days).

Filing lag (calendar days)	Frequency	Percentage	Cumulative
0	1470089	98.57%	98.57%
1	20761	1.39%	99.97%
2	285	0.02%	99.98%
3	89	0.01%	99.99%
4	47	0.00%	99.99%
5	26	0.00%	100.00%
6	14	0.00%	100.00%
7	6	0.00%	100.00%
8	4	0.00%	100.00%
9	3	0.00%	100.00%
10 or more	44	0.00%	100.00%
