SEC EDGAR Parser

This skill enables the agent to interact with the SEC's EDGAR system to retrieve corporate filings and extract financial data.

Workflow

1. Identify Company & Filing

  • Find CIK: Use the company ticker (e.g., AAPL, TSLA) to find the Central Index Key (CIK). The SEC maps tickers to CIKs via a public JSON file (company_tickers.json).
  • Select Filing Type: Determine which form is needed (e.g., 10-K for annual reports, 10-Q for quarterly, 8-K for current events).

2. Fetch Filing Metadata

  • Use the SEC's submission history API: https://data.sec.gov/submissions/CIK{cik_padded}.json
  • This JSON contains a list of all recent filings with their accession numbers, filing dates, and form types.

3. Locate & Download Document

  • Construct the URL for the specific filing document. The format typically involves the CIK (without leading zeros) and the Accession Number (with hyphens removed).
  • HTML URL Pattern: https://www.sec.gov/Archives/edgar/data/{cik}/{accession_number}/{primary_document}
  • Interactive Data (XBRL): Often available as XML or JSON.

4. Parse Content

  • Text Extraction: Use BeautifulSoup to strip HTML tags and extract sections (e.g., "Item 1A. Risk Factors", "Item 7. MD&A").
  • Table Extraction: Use pd.read_html() to convert HTML tables into Pandas DataFrames.

Key Requirements

  • User-Agent: The SEC requires a valid User-Agent header in the format Sample Company Name AdminContact@sample.com. Requests without this will be blocked.
  • Rate Limiting: The SEC limits requests to ~10 per second. Scripts should include slight delays if making many requests.

Bundled Scripts

scripts/sec_utils.py

A utility script to:

  1. Get CIK from Ticker.
  2. Get recent filings list for a company.
  3. Download a specific filing's text.

Example Usage

Get Recent 10-K Filings

from scripts.sec_utils import get_cik, get_filings

cik = get_cik("AAPL")
filings = get_filings(cik, form_type="10-K")
print(filings.head())

Download a Filing

from scripts.sec_utils import download_filing
# Use the URL from the filings dataframe
text = download_filing(filings.iloc[0]['url'])
