Parse SEC EDGAR HTML documents into a tree of elements that correspond to the visual structure of the document.

See Demo | Read Docs | Join Discussions | Join Discord

Overview

The sec-parser project simplifies extracting meaningful information from SEC EDGAR HTML documents by organizing them into semantic elements and a tree structure. Semantic elements might include section titles, paragraphs, and tables, each classified for easier data manipulation. This forms a semantic tree that corresponds to the visual and informational structure of the document. If you're familiar with the Image Semantic Segmentation concept, it's the same but applied to HTML documents.

This tool is especially beneficial for Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLM) applications by streamlining data pre-processing and feature extraction.

Key Use-Cases

sec-parser is versatile and can be applied in various scenarios, including but not limited to:

Financial and Regulatory Analysis

• Financial Analysis: Extract financial data from 10-Q and 10-K filings for quantitative modeling.
• Risk Assessment: Evaluate risk factors or Management's Discussion and Analysis sections for qualitative analysis.
• Regulatory Compliance: Assist in automating compliance checks for the legal teams.
• Flexible Filtering: Easily filter SEC documents by sections and types, giving you precisely the data you need.

Analytics and Data Science

• Academic Research: Facilitate large-scale studies involving public financial disclosures, sentiment analysis, or corporate governance exploratory.
• Analytics Ready: Integrate parsed data seamlessly into popular analytics tools for further analysis and visualization.

AI and Machine Learning

• Cutting-Edge AI for SEC EDGAR: Apply advanced AI techniques like MemWalker to navigate and extract and transform complex information from SEC documents efficiently. Learn more in our blog post: Cutting-Edge AI for SEC EDGAR: Introducing MemWalker.
• AI Applications: Leverage parsed data for various AI tasks such as text summarization, sentiment analysis, and named entity recognition.
• Data Augmentation: Use authentic financial text to train and test machine learning models.

Causal AI

• Causal Analysis: Use parsed data to understand cause-effect relationships in financial data, beyond mere correlations.
• Predictive Modeling: Enhance predictive models by incorporating causal relationships, leading to more robust and reliable predictions.
• Decision Making: Aid decision-making processes by providing insights into the potential impact of different actions, based on causal relationships identified in the data.

Large Language Models

• LLM Compatible: Use parsed data to facilitate complex NLU tasks with Large Language Models like ChatGPT, including question-answering, language translation, and information retrieval.

These use-cases demonstrate the flexibility and power of sec-parser in handling both traditional data extraction tasks and facilitating more advanced AI-driven analysis.

Getting Started

This guide will walk you through the process of installing the sec-parser package and using it to extract the "Segment Operating Performance" section as a semantic tree from the latest Apple 10-Q filing.

Tip

To run the example code in a ready-to-code environment, you can use GitHub Codespaces. Click the button below to open the example code below in a codespace and start experimenting with sec-parser:

Installation

First, install the sec-parser package using pip:

pip install sec-parser

To run the example code in this README, you'll also need the sec_downloader package:

pip install sec-downloader

Usage

Once you've installed the necessary packages, you can start by downloading the filing from the SEC EDGAR website. Here's how you can do it:

from sec_downloader import Downloader

# Initialize the downloader with your company name and email
dl = Downloader("MyCompanyName", "[email protected]")

# Download the latest 10-Q filing for Apple
html = dl.get_filing_html(ticker="AAPL", form="10-Q")

Note

The company name and email address are used to form a user-agent string that adheres to the SEC EDGAR's fair access policy for programmatic downloading. Source

Tip

Read sec-downloader documentation (and examples) for more advanced usage (such as downloading three latest Apple 10-Q filings instead of just one, or downloading based on a specific CIK or Filing ID (i.e. accession number)).

Now, we can parse the filing HTML into a list of semantic elements:

# Utility function to make the example code a bit more compact
def print_first_n_lines(text: str, *, n: int):
    print("\n".join(text.split("\n")[:n]), "...", sep="\n")

import sec_parser as sp

elements: list = sp.Edgar10QParser().parse(html)

demo_output: str = sp.render(elements)
print_first_n_lines(demo_output, n=7)

TopSectionTitle: PART I  —  FINANCIAL INFORMATION
TopSectionTitle: Item 1.    Financial Statements
TitleElement: CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)
SupplementaryText: (In millions, except number of ...housands and per share amounts)
TableElement: Table with 24 rows, 80 numbers, and 1058 characters.
SupplementaryText: See accompanying Notes to Conde...solidated Financial Statements.
TitleElement: CONDENSED CONSOLIDATED STATEMEN...OMPREHENSIVE INCOME (Unaudited)
...

Tip

FAQ: How do I get the text of each element (or all of the document)? How do I get all of the text in a specific section?

Use the element.text field. Check out this notebook for a full example.

We can also construct a semantic tree to allow for easy filtering by parent sections:

tree = sp.TreeBuilder().build(elements)

demo_output: str = sp.render(tree)
print_first_n_lines(demo_output, n=7)

TopSectionTitle: PART I  —  FINANCIAL INFORMATION
├── TopSectionTitle: Item 1.    Financial Statements
│   ├── TitleElement: CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)
│   │   ├── SupplementaryText: (In millions, except number of ...housands and per share amounts)
│   │   ├── TableElement: Table with 24 rows, 80 numbers, and 1058 characters.
│   │   ├── SupplementaryText: See accompanying Notes to Conde...solidated Financial Statements.
│   ├── TitleElement: CONDENSED CONSOLIDATED STATEMEN...OMPREHENSIVE INCOME (Unaudited)
...

Tip

Feel free to experiment with the example code provided above. You can easily do this by launching a GitHub Codespace for the sec-parser repository, which will set up a development environment for you in the cloud:

This is a great way to play around with the code without having to set up anything on your local machine. Give it a try!

For more examples and advanced usage, you can continue learning how to use sec-parser by referring to the User Guide, Developer Guide, and Documentation.

This was an example of 10-Q SEC Form parsing. How do we parse other SEC Form types, such as 10-K, 8-K, S-1, etc.?

Please refer to this document.

Best Practices

How to Import Modules In Your Code

To ensure your code remains functional even when we change the internal structure of sec-parser, it's recommended to avoid deep imports. Here is an example of a deep import (not recommended):

Caution

from sec_parser.semantic_tree.internal_utils.core import SomeInternalClass

Instead, use the suggested ways to import modules from sec-parser:

Root Import (prefix)

• import sec_parser as sp. This imports the main package as sp. You can then access its functionalities using sp. prefix.

Root Import (direct)

• from sec_parser import SomeClass: This allows you to directly use SomeClass without any prefix.

Submodule Import (prefix)

• import sec_parser.semantic_tree: This imports the semantic_tree submodule, and you can access its classes and functions using semantic_tree. prefix.

Submodule Import (direct)

• from sec_parser.semantic_tree import SomeClass: This imports a specific class SomeClass from the semantic_tree submodule.

Note

The main package sec_parser contains only the most common functionalities. For specialized tasks, please use submodule or submodule-level imports.
