Crawl and fetch all publicly-traded companies annual reports from SEC's EDGAR database.

edgar-crawler is an optimized toolkit that retrieves textual information from financial reports, such as 10-K, 10-Q or 8-K filings.

More specifically, it can:

• Crawl and download financial reports for each publicly-traded company, for specified years, through the edgar_crawler.py module.
• Extract and clean specific text sections, such as Risk Factors, MD&A, and others, through the extract_items.py module. Currently, we only support extraction of 10-K filings (i.e., annual reports).

The purpose of EDGAR-CRAWLER is to speed up research and experiments that rely on financial information, as they are widely seen in the research literature of economics, finance, business and management.

• 2023-01-16: EDGAR-CORPUS, a derivative dataset generated from EDGAR-CRAWLER, is available as a HuggingFace 🤗 dataset card. See Accompanying Resources for more details.
• 2022-10-13: Updated documentation and fixed a minor import bug.
• 2022-04-03: EDGAR-CRAWLER is available for Windows systems too.
• 2021-11-11: We presented EDGAR-CRAWLER at ECONLP 2021, which took place in conjunction with EMNLP at the Dominican Republic.
• 2021-09-16: The research paper is accepted at the 3rd Economics and Natural Language Processing Workshop.

• Before starting, it's recommended to create a new virtual environment using Python 3.8 or greater. We recommend installing and using Anaconda for this.
• Install dependencies via pip install -r requirements.txt

• Before running any script, you should edit the config.json file.

  • Arguments for edgar_crawler.py, the module to download financial reports:
    • --start_year XXXX: the year range to start from (default is 2021)
    • --end_year YYYY: the year range to end to (default is 2021)
    • --quarters: the quarters that you want to download filings from (List).
      Default value is: [1, 2, 3, 4].
    • --filing_types: list of filing types to download.
      Default value is: ['10-K', '10-K405', '10-KT'].
    • --cik_tickers: list or path of file containing CIKs or Tickers. e.g. [789019, "1018724", "AAPL", "TWTR"]
      In case of file, provide each CIK or Ticker in a different line.
      If this argument is not provided, then the toolkit will download annual reports for all the U.S. publicly traded companies.
    • --user_agent: the User-agent (name/email) that will be declared to SEC EDGAR.
    • --raw_filings_folder: the name of the folder where downloaded filings will be stored.
      Default value is 'RAW_FILINGS'.
    • --indices_folder: the name of the folder where EDGAR TSV files will be stored. These are used to locate the annual reports. Default value is 'INDICES'.
    • --filings_metadata_file: CSV filename to save metadata from the reports.
    • --skip_present_indices: Whether to skip already downloaded EDGAR indices or download them nonetheless.
      Default value is True.
  • Arguments for extract_items.py, the module to clean and extract textual data from already-downloaded 10-K reports:
    • --raw_filings_folder: the name of the folder where the downloaded documents are stored.
      Default value s 'RAW_FILINGS'.
    • --extracted_filings_folder: the name of the folder where extracted documents will be stored.
      Default value is 'EXTRACTED_FILINGS'.
      For each downloaded report, a corresponding JSON file will be created containing the item sections as key-pair values.
    • --filings_metadata_file: CSV filename to load reports metadata (Provide the same csv file as in edgar_crawler.py)
    • --items_to_extract: a list with the certain item sections to extract.
      e.g. ['7','8'] to extract 'Management’s Discussion and Analysis' and 'Financial Statements' section items.
      The default list contains all item sections.
    • remove_tables: Whether to remove tables containing mostly numerical (financial) data. This work is mostly to facilitate NLP research and often numerical tables are not useful
    • skip_extracted_filings: Whether to skip already extracted filings or extract them nonetheless.
      Default value is True.

• To download financial reports from EDGAR, run python edgar_crawler.py

• To clean and extract specific item sections from already-downloaded 10-K documents, run python extract_items.py.

  • Reminder: We currently support the extraction of 10-K documents.
