sec-cik-mapper

sec-cik-mapper is a Python package for generating mappings between stock and mutual fund identifier data provided by the SEC.

Features

Generate up-to-date mappings from the SEC as native Python dictionaries
Mappings for both stocks and mutual funds
Mapping data exposed as a raw pandas dataframe for custom data processing and usage
Full support for PEP 484-style type hints and the mypy type checker
Pre-generated mappings, updated daily, available from GitHub and jsDelivr for use outside of Python
Support for Python 3.6+

Quick Start

Installation

Install and update this package using pip:

$ pip install -U sec-cik-mapper

Basic Usage

Stocks

>>> from sec_cik_mapper import StockMapper
>>> from pathlib import Path

# Initialize a stock mapper instance
>>> mapper = StockMapper()

# Get mapping from CIK to tickers
>>> mapper.cik_to_tickers
{'0000320193': {'AAPL'}, '0000789019': {'MSFT'}, '0001652044': {'GOOG', 'GOOGL'}, ...}

# Get mapping from ticker to CIK
>>> mapper.ticker_to_cik
{'AAPL': '0000320193', 'MSFT': '0000789019', 'GOOG': '0001652044', ...}

# Get mapping from CIK to company name
>>> mapper.cik_to_company_name
{'0000320193': 'Apple Inc.', '0000789019': 'Microsoft Corp', '0001652044': 'Alphabet Inc.', ...}

# Get mapping from ticker to company name

Supported Mappings

Mappings can be formed between the following SEC identifiers and metadata:

Key	Value	`StockMapper`	`MutualFundMapper`
`CIK`	`Set(Tickers)`	✅	✅
`CIK`	`Company Name`	✅
`CIK`	`Exchange`	✅
`Exchange`	`Set(CIKs)`	✅
`Exchange`	`Set(Tickers)`	✅
`Ticker`	`CIK`	✅	✅
`Ticker`	`Company Name`	✅
`Ticker`	`Exchange`	✅
`CIK`	`Set(Series IDs)`		✅
`CIK`	`Set(Class IDs)`		✅
`Class ID`	`CIK`		✅
`Class ID`	`Ticker`		✅
`Series ID`	`CIK`		✅
`Series ID`	`Set(Class IDs)`		✅
`Series ID`	`Set(Tickers)`		✅
`Ticker`	`Class ID`		✅
`Ticker`	`Series ID`		✅

Pre-generated Mappings

Pre-generated mappings are also available for download and use outside of Python (e.g. manually or via automated scripts/curl requests). These mappings are updated daily via a fully automated daily CRON job, which fetches, transforms, validates, and uploads the latest mapping data from the SEC to GitHub (save location: sec-cik-mapper/mappings · GitHub). These mappings are available for download and usage from both GitHub and the jsDelivr CDN.

Example Usage

Example curl commands, which download the specified mapping files and saves them to the current working directory:
