How to do Agentic RAG on SEC EDGAR Filings

Financial document analysis is the backbone of informed investing and corporate decision-making. Public companies are required to file periodic reports (10-K annual reports, 10-Q quarterly reports, etc.) with the SEC, and these filings are packed with critical information. Investors and analysts rely on SEC filings to evaluate company performance, risks, and growth prospects. However, combing through hundreds of pages of financial statements, footnotes, and management discussions is time-consuming and complex. In fast-paced markets, missing a key detail in an SEC EDGAR filing could mean overlooking emerging risks or opportunities. This is why automating and enhancing financial document analysis has become crucial. Recent advances in AI – particularly Large Language Models (LLMs) – offer new ways to digest these filings quickly. One promising approach is Retrieval-Augmented Generation (RAG), which grounds LLMs on relevant document data to generate accurate, context-informed answers. In this blog, we’ll explore how an agentic RAG framework can be applied to SEC EDGAR filings to supercharge financial analysis, appealing to both engineers (interested in the technical “how”) and financial analysts (focused on the actionable insights).

Why Automating Financial Document Analysis Is Crucial

Modern financial analysis often requires synthesizing information from multiple documents and periods. For example, to truly understand a company’s trajectory, an analyst might need to compare metrics across several 10-Qs and 10-Ks, read through management’s commentary in MD&A sections, and even look at earnings call transcripts. Critical insights – such as performance trends, changes in strategy, or shifts in sentiment – emerge from cross-document analysis​. Doing this manually is not only tedious but also prone to error and delay. In fact, traditional single-document analysis fails to capture the broader context needed for informed decision-making​.

The volume and complexity of SEC filings add to the challenge. A single annual report can exceed 200 pages of dense text and tables, often in inconsistent formats. Manually reading and extracting data from such filings (especially under time pressure) risks missing important details. There is little tolerance for error – a missed clause in the 10-K or a mis-read table can directly impact investment decisions. Furthermore, LLMs on their own are not a perfect solution: since they’re trained on historical data, they might not contain the latest filings, and they can “hallucinate” facts if asked questions beyond their knowledge cutoff. This makes a strong case for RAG-based systems that can inject up-to-date, authoritative data (like EDGAR filings) into the AI’s reasoning process​.

In summary, automating SEC filing analysis is both a necessity (to keep up with information flow and avoid blind spots) and an opportunity (to leverage AI for deeper, faster insight). The next sections introduce how Retrieval-Augmented Generation, especially with an agentic twist, addresses these needs.

What is Retrieval-Augmented Generation (RAG)?

Retrieval-Augmented Generation (RAG) is an AI framework that combines information retrieval with generative AI to produce answers that are both contextually relevant and grounded in real data. Instead of relying solely on a language model’s internal knowledge (which may be stale or insufficient), RAG actively searches a knowledge base for relevant documents and feeds those into the LLM to inform its output. This ensures the model’s responses are backed by actual source content, greatly reducing errors and hallucinations. The concept originated from a 2020 Facebook AI Research paper and has since become a go-to approach for applications like question answering, summarization, and knowledge extraction in specialized domains​.

In practice, a RAG system will take a user query, retrieve a set of documents or snippets (for example, sections of a 10-K that relate to the question), and then prompt the LLM with both the query and the retrieved content. The LLM’s job is to synthesize a coherent response that directly uses that content. By doing so, RAG grounds the generation on factual information – for instance, if asked “What were Acme Corp’s profit margins last year and how do they compare to the previous year?”, a RAG system would fetch the relevant parts of Acme’s last two annual reports and have the LLM base its answer on those figures (rather than the model guessing from training data).

Why is RAG beneficial for financial documents? Because it marries the best of both worlds: the precision of database or search systems with the flexibility of language generation. Financial filings are full of numbers and exact statements that must be quoted correctly – the retrieval component ensures the model has those facts on hand. Meanwhile, the generative component can interpret and narrate those facts, for example, explaining trends or summarizing a 100-page filing into a few bullet points. This combination is particularly powerful for SEC filings, where one might query unstructured text (“What litigation risks has the company mentioned?”) and need an answer that is both accurate and well-formulated. RAG provides an architecture to accomplish exactly that.

Introducing Agentic RAG for Financial Analysis

Basic RAG retrieves documents and answers questions, but Agentic RAG takes it a step further by making the retrieval and answering process iterative, adaptive, and self-correcting. In an agentic RAG framework, the system behaves as an “agent” that can plan, reason, and take multiple steps to fulfill a complex information request. This approach has been described in research as Corrective Retrieval-Augmented Generation (CRAG)​ – essentially RAG enhanced with feedback loops.

What does this mean in practice? An agentic RAG system analyzing SEC filings will not just do a single retrieval pass. It will:

  • Plan the task: First, break down the query or task into parts (e.g., identify which company, which filings, which sections might be relevant).
  • Retrieve iteratively: Pull in information, then evaluate if that information is sufficient. If not, the system can reformulate queries, search different databases, or grab additional documents in a second pass.
  • Self-check and refine: Before producing the final answer, the system uses internal checks. For example, it can use an LLM to grade each retrieved chunk’s relevance to the query, filtering out anything off-topic. This corrective step ensures that only high-quality, pertinent info goes into the answer.
  • Act autonomously: This agent can decide on its own to fetch a missing piece of data (e.g., “No revenue info found in the 10-K MD&A – maybe check the 10-Q filings or a press release?”) without a human explicitly telling it to do so​.

By being “agentic,” the RAG system mimics what a diligent analyst would do: if one document doesn’t have the answer, look for another; double-check that the gathered data truly answers the question; and compile the findings into a coherent whole. The benefit is a more robust and accurate pipeline, especially important in finance where answers must be backed by facts from the right periods and sources.

Agentic RAG is particularly powerful for multi-document financial analysis. Researchers have demonstrated that such frameworks can consolidate and contrast insights from several filings, track performance over time, and even detect sentiment or language changes across reports. In essence, it automates the tedious parts of poring over documents, while an AI agent does the heavy lifting with attention to detail.

Next, let’s walk through a step-by-step guide on how to apply an agentic RAG approach to SEC EDGAR filings, from data ingestion all the way to generating useful insights.

Applying Agentic RAG to SEC EDGAR Filings: Step-by-Step

In this section, we’ll outline a practical, technical roadmap for implementing an agentic RAG workflow on SEC EDGAR filings. Whether you’re an engineer looking to build such a system, or a financial analyst curious about how the “AI magic” works under the hood, these steps will illustrate the process:

Step 1: Analyze the Query and Identify Relevant Filings

Everything begins with understanding the user’s query or task. In financial analysis, questions often specify a company (or multiple companies), a time frame, and a topic. For example: “Compare ACME Corp’s gross margin and revenue growth over the last 2 years.” An agentic RAG system first clarifies the task objective and scope​. Key sub-tasks include:

  • Identify the target company or companies: Map company names to their tickers (e.g., “Apple” → AAPL) to know which filings to retrieve​.
  • Determine the document types needed: For financial metrics like gross margin, the system should pull 10-Ks/10-Qs (annual and quarterly reports). If the query was about a specific event, maybe an 8-K or a press release is relevant​.
  • Determine the time range: Parse any date references (e.g., “last 2 years” means you need filings from the past two fiscal years)​.

By structuring the query, the agent defines which EDGAR filings are in scope. This might result in, for instance, a decision to fetch ACME’s 10-K filings for 2023 and 2022, plus the latest 10-Qs from 2024. Having this clarity up front prevents wasted effort on irrelevant data.

Step 2: Plan the Retrieval Strategy

Not all parts of a filing are equally useful for a given question. Once the relevant documents are identified, the next step is to devise a retrieval plan – essentially, deciding where in those documents to look and how to query them. This is crucial because SEC filings are large, and naively feeding an entire 200-page 10-K into an LLM is neither efficient nor feasible (due to context length limits and noise).

Important considerations for the retrieval strategy include:

  • Define the retrieval scope: Figure out which sections of the filing likely contain the answer. For instance, if the task is to extract financial metrics, the scope might be the financial statements or Selected Financial Data section. If the task is to summarize management’s perspective, the scope would be the Management Discussion & Analysis (MD&A). By narrowing scope, the system reduces noise and focuses on relevant chunks.
  • Effective chunk targeting: If summarizing an entire filing, maybe one representative chunk per major section (Business Overview, Risk Factors, Financial Statements, etc.) should be retrieved to give a holistic view. If answering a specific factual question, perhaps only a single table or paragraph is needed.
  • Query reformulation for vector search: The agent may transform the user’s natural language query into a more specific search query that matches how the information is stated in filings​. For example, the user asks “Provide revenue breakdown by product for Apple” – filings might not use those exact words. A better internal query might be “Net sales by product for the last six quarters: iPhone, Mac, iPad…” to directly retrieve the relevant table​. This increases the chance that the vector similarity search will surface the correct data.

The output of this planning step is essentially a set of targeted search queries and an understanding of which parts of each document to search within. This plan optimizes the subsequent retrieval so we pull only the most pertinent information.

Step 3: Ingest and Chunk the Filings

With a plan in hand, it’s time to fetch the actual documents and prepare them for retrieval. SEC EDGAR filings can be obtained via EDGAR’s API or by scraping the HTML/text of the filings from SEC’s website. Once retrieved, we need to preprocess and chunk these documents for our vector database or search index.

Document chunking is the process of splitting a long document into smaller, semantically meaningful pieces (chunks). Proper chunking is vital for two reasons: it ensures that each chunk can fit in the LLM context if retrieved, and it improves the relevance of search results by keeping chunks focused. Here’s how to approach it for SEC filings:

  • Clean and normalize text: Remove unnecessary formatting, fix OCR errors if any, and unify units or terms if needed (for example, ensure consistent use of terms like “Net Sales” vs “Revenue” if combining sources).
  • Segment into logical sections: Use the document structure – SEC filings are usually well-structured with sections and headings. For a 10-K, you might chunk it by major headings (Business Overview, Risk Factors, MD&A, Financial Statements, Notes, etc.), and further subdivide large sections into paragraphs or bullet-point groups. Each chunk should ideally represent a standalone idea or data set (e.g., one risk factor, or one table).
  • Add metadata: Tag each chunk with useful metadata such as the company name, report type (10-K or 10-Q), filing date or fiscal period, and the section title it came from​. This metadata will later help in filtering or prioritizing results. For instance, if we know we only need Q4 2023 data, we can instruct the retriever to prioritize chunks with that period tag. The paper implementing agentic RAG highlights how tagging sections like “Revenue Breakdown” with the corresponding fiscal period improves retrieval accuracy.

This ingestion and chunking process might be done on-the-fly, but in practice, it’s often done offline as a pre-processing step for an entire repository of documents​. Engineering-wise, one could process a batch of filings, chunk them, and load them into a vector database ahead of time, so that at query time, the retrieval is fast and doesn’t require reprocessing the raw text.​

Step 4: Retrieve Relevant Chunks

Now that the filings are chunked and indexed (typically in a vector store for semantic search, or alternatively using keyword search indices), the agent performs the retrieval step. This involves taking the refined queries from Step 2 and searching for the most relevant chunks in our corpus.

Using a vector similarity search, each chunk of text has an embedding, and we compare the embedding of the query to find similar content. For example, an embedding of the query “gross margin last 2 years” should closely match chunks that contain gross margin figures from the last two years of filings. We then retrieve the top-n most similar chunks above a certain similarity threshold​.

Key points for retrieval:

  • How many chunks to retrieve? This can be a fixed number (e.g., top 5 chunks) or dynamic based on a similarity cutoff. One strategy is to take all chunks above a similarity score (or within a top percentile of relevance)​. Another is a hybrid: always take top 3, but also include any others that are very close in score to the top ones. The goal is to capture all relevant info but avoid too much data that might confuse the model.
  • Multi-file, multi-section retrieval: Because our use case is multi-document, the retrieved set might include, say, a chunk from the 2023 10-K MD&A where gross margin is discussed, another chunk from the 2022 10-K with the prior year’s number, and perhaps a piece of a quarterly report if needed. The agent keeps track of which document each chunk came from (via metadata) so we maintain context.

At this stage, we have a collection of candidate text snippets that likely contain the answers or information needed for the query. However, not all of these may actually be relevant or high-quality, which leads us to a critical corrective step.

Step 5: Apply Corrective Retrieval Mechanisms

One hallmark of an agentic RAG system is the inclusion of a feedback loop to refine the retrieved information before final answer generation. There are two major mechanisms here: relevance filtering and fallback retrieval.

(a) Relevance Filtering (Document Grading): The agent uses an LLM (or other classifier) to review each retrieved chunk and decide if it truly helps answer the question​. Essentially, the model is asked (internally) a yes/no: “Is this chunk about what the user is asking?” For instance, if the query is about gross margins and one retrieved chunk is about a different metric (say, a balance sheet item or an unrelated footnote), the LLM can flag it as irrelevant. Chunks deemed irrelevant are dropped from the context. This ensures that the final context given to the answer generator is noise-free and precise​​. Such self-reflection by the agent prevents garbage-in, garbage-out issues.

(b) Fallback Retrieval: If after filtering, the agent finds that not enough information remains (or perhaps the information looks incomplete – e.g., we got data for 2023 but not 2022 in our margin question), it can proactively attempt alternative retrievals​​. Some fallback strategies include:

  • Refine the search query: Perhaps the initial query missed a keyword. The agent might reformulate or broaden the query and hit the vector store again to grab more chunks​.
  • Switch document sources: If the expected info isn’t in the documents you thought, consider other filings. For example, if a detail wasn’t in the 10-K, maybe the earnings call transcript or a 8-K filing has it​. The agent can pull those in if available.
  • External search: In cases where the data might not be in any internal documents (or if the internal data is insufficient), an advanced agent could even do a web search for supplementary info​ (for instance, checking if a number was mentioned in a press release or financial news). This is less common for structured finance questions but useful for context or definitions.

Through these corrective mechanisms, the RAG workflow becomes robust. It doesn’t stop at the first try; it mimics how an analyst might realize “I need more data on that, let me dig deeper.” The outcome is a set of verified-relevant chunks that cover the question comprehensively. Now we’re ready to synthesize the answer.

Step 6: Synthesize Insights from Multiple Filings

Finally, with a curated set of context snippets at hand, the system uses the LLM to generate the output. The user’s original query is combined with the filtered, relevant chunks as the prompt to the generative model​. Because the model now has factual data points in its context window, it can produce a response that is grounded in those facts.

During this generation step, the agent can be instructed to produce certain formats depending on the task:

  • Narrative answers (unstructured): e.g., a written analysis that compares the metrics and explains trends.
  • Bullet points: if the user asked for key highlights.
  • Tables or JSON (structured output): This is particularly useful for financial data extraction tasks. For example, the model could output a JSON object or a Markdown table of the gross margins for each year, which can then be easily read or further processed​. Advanced workflows like the one used by Captide even enforce JSON schemas to ensure consistency of output when needed​.

The generative model, guided by the retrieved evidence, might produce something like:

ACME Corp’s gross margin was 45.2% in 2023, up from 42.5% in 2022​. This improvement was primarily driven by a more profitable product mix and cost efficiencies in 2023, as noted in the MD&A​. Over the same period, revenue grew 10%, from $10.0B in 2022 to $11.0B in 2023, indicating that the margin expansion contributed significantly to the bottom line​.”

This final answer synthesizes data from multiple filings: it took the gross margin from 2022’s 10-K and 2023’s 10-K, and also pulled an explanatory sentence from the MD&A. An analyst reading this gets a concise answer with evidence, which is exactly the power of RAG applied to financial documents.

Benefits of Agentic RAG in SEC Filing Analysis

By following the above steps, we create a pipeline that greatly accelerates and enhances financial analysis. To summarize the key benefits of applying agentic RAG to EDGAR filings:

  • Speed and Efficiency: What used to take an analyst days of reading can be answered in minutes. The automation sifts through large documents at lightning speed and surfaces exactly what’s needed.
  • Cross-Document Insight: The agent can seamlessly pull together information from multiple filings (e.g., a 10-K and several 10-Qs) to provide a consolidated answer. This is invaluable for time-series analysis, trend identification, and consistency checks across reports​​.
  • Improved Accuracy and Compliance: Because answers are directly drawn from official filings, the likelihood of factual errors is minimized. Plus, the approach naturally lends itself to providing citations or references (so you can always double-check the source in the SEC document). This transparency is a big win in an industry where trust and verification are important.
  • Handles Complexity: Financial filings include tables, text, legal jargon, and more. An agentic RAG system can be taught to handle different sections appropriately – for example, splitting out tables for data extraction, reading footnotes for context, and understanding that “MD&A” contains forward-looking commentary.
  • Reduced Cognitive Load: For financial analysts, this means they spend less time on rote information gathering and more time on high-level analysis and decision-making. They can ask deeper or more “what-if” questions because getting answers is easier.
  • Adaptability: Need to analyze a new company or a different metric? The same pipeline can be quickly re-directed without starting from scratch. As new filings come out, they can be added to the database, keeping the knowledge base always up-to-date.

In essence, agentic RAG acts like a tireless research assistant: it combs through EDGAR for you, cross-checks information, and presents digestible insights. This doesn’t replace the analyst, but rather augments their capabilities – allowing humans to focus on judgment and interpretation armed with the AI-curated facts.

From Theory to Practice: Agentic RAG in Action

Building an agentic RAG pipeline for SEC filings from scratch involves many moving parts – from data ingestion and vector databases to LLM integration and agent logic. It’s a rewarding endeavor for engineers, but it can also be resource-intensive to maintain and fine-tune (think of the constant updates to embeddings, new filings every quarter, and the need to ensure accuracy at every step)​. This is where leveraging a specialized solution can save tremendous time.

One emerging solution is the Captide API, which encapsulates the entire agentic RAG workflow as a service. The Captide platform is designed specifically for financial analysis use cases, automating the extraction of insights and metrics from regulatory filings and other financial documents​.
