Version 1.0

Using Python, take a list of Stock Ticker Symbols from a file and (if it exists) get the associated SEC CIK with the Company Name written into a JSON output file. This uses python script uses the SEC Edgar website's searching functionality.

To run this have the python dependencies installed: beautifulsoup json pickle requests

Compile the latest Stock Ticker Symbols into a single file. For this build I used the NASDAQ csv's available here: http://www.nasdaq.com/screening/company-list.aspx

After copying and appending them into a single file I sorted and filtered one uniques

cat unsorted_single_entry_file | sort | uniq > data/newest_ticker_symbol_file.txt

Make sure to update the TICKERS_FILE line too in convert_ticker_to_cik.py

Defaults for reference assume the all_tickers and output file go in the ./data directory:

TICKERS_FILE = "data/all_tickers.txt"

OUTPUT_JSON_FILE_PATH = "data/ticker_to_cik_mapping.json"

To run: ./convert_ticker_to_cik.py
