  3. Chain of Thoughts Technique: This approach takes AI through a logical progression of thought, ideal for detailed financial analyses and predictions.


Introduction to Prompt Engineering

Ever wondered how an AI could sift through the vast seas of data and pull out not just any answer, but the right answer? Welcome to the world of prompt engineering, the unsung hero of the AI workflow. Prompt engineering is not just about asking questions; it’s about asking the right questions in the right way. This is crucial in finance, where the accuracy of an answer can mean the difference between profit and loss.

Tips and Tricks for Effective Prompts

  1. Structured Formats Like JSON/XML: Think of JSON or XML as the polite way of speaking to your AI. By structuring your prompts in these formats, you're essentially giving the AI a roadmap of what to look for, making it easier for it to parse and process complex financial queries. For instance, when asking an AI to analyze quarterly financial reports, structuring the prompt with clear markers for "revenue," "expenses," "net profit," and "year-over-year growth" can lead to more accurate and relevant responses.


Let's consider an example where a financial analyst wants to use an LLM to extract key data from a quarterly earnings report. The data includes revenue, expenses, net profit, and year-over-year growth. Here's how you could structure this request using JSON format versus a non-JSON format, highlighting the clarity and organization provided by JSON:

Non-JSON Prompt:

"Please read the attached quarterly earnings report and tell me the revenue, expenses, net profit, and year-over-year growth."

JSON-Formatted Prompt:

{ "document": "Quarterly Earnings Report", "queries": [ { "query": "Extract revenue", "context": "total revenue for the current quarter" }, { "query": "Extract expenses", "context": "total operating expenses for the current quarter" }, { "query": "Extract net profit", "context": "net profit after taxes for the current quarter" }, { "query": "Year-over-year growth", "context": "compare current quarter revenue to the same quarter last year" } ] }

Comparison and Explanation:

Non-JSON Prompt:

  • The request is straightforward but lacks structure. The LLM has to interpret the task and decide how to search for each piece of information within a potentially long document. It might miss specifics such as the time frame for "year-over-year growth" or the precise definition of "expenses."

JSON-Formatted Prompt:

  • Structured and Clear: Each part of the request is clearly separated into distinct queries, making it easier for the LLM to process each task individually.

  • Context Provided: By including a specific context for each query, the LLM can focus its search and extraction process more accurately. For example, specifying "for the current quarter" or "compare current quarter revenue to the same quarter last year" helps the model to locate and extract the exact figures needed without ambiguity.

  • Enhanced Accuracy: The structured format reduces the likelihood of errors in interpreting the prompt. The LLM can more reliably match the queries to the correct sections of the document, leading to more accurate results.

By using JSON to structure the prompt, the financial analyst can guide the LLM more effectively, ensuring that the AI understands each part of the request and responds with precise information. This method is particularly useful in finance, where data accuracy is crucial and documents can be complex and densely packed with figures.


  1. Example Formatting: Sometimes, the best way to teach is by example. When crafting prompts, including examples can guide the AI in understanding the context and the specificity of the information required. For example, if you need an AI to extract risk factors from investment prospectuses, showing it a formatted example of how those factors are typically discussed can significantly improve the relevance of its extractions.

  2. Chain of Thoughts Technique: This technique involves guiding the AI through a logical progression of thought, almost like solving a puzzle piece by piece. It’s especially useful in complex financial analyses where one question leads to another. For instance, you might start by asking the AI to identify the most volatile stocks in the last quarter, then follow up with prompts that ask why those stocks were volatile, and what external factors influenced their performance.


Let's consider an example involving financial forecasting where we want to assess the impact of an upcoming economic policy change on stock market volatility. This example will compare the effectiveness of a standard prompt versus a prompt enhanced with a Chain of Thoughts (COT) technique.

Non-COT Prompt:

"Analyze how the new economic policy announced last week might affect stock market volatility."

Chain of Thoughts (COT) Prompt:

"First, identify the main elements of the new economic policy announced last week. Next, analyze how similar policies have affected stock markets in the past. Then, consider the current economic conditions and market sentiment. Finally, synthesize this information to predict how this policy might affect stock market volatility."

Explanation and Comparison:

Non-COT Prompt:

  • The prompt is straightforward but broad and leaves much up to the AI's interpretation and approach. The model might directly attempt to answer the query without a structured method of analysis, leading to potentially superficial or generalized insights.

  • Lack of specificity can result in the LLM missing crucial steps in the thought process, such as examining historical precedents or considering current market conditions, which can lead to less accurate or insightful predictions.

Chain of Thoughts (COT) Prompt:

  • Structured Analysis: The COT prompt breaks down the task into a sequence of logical steps. This guides the LLM through a detailed and methodical analysis, improving the depth and relevance of the output.

  • Historical Context and Comparison: By instructing the LLM to analyze how similar policies have impacted the market in the past, the model can draw more informed parallels and contrasts, which enhances the predictive accuracy.

  • Consideration of Current Conditions: Including steps to consider current economic conditions and market sentiment ensures that the analysis is not only historical but also tailored to the present situation. This is crucial in financial forecasting where current conditions can significantly influence outcomes.

  • Synthesis for Prediction: Finally, the prompt directs the LLM to synthesize the gathered insights to make a prediction. This step ensures that the answer is comprehensive and considers all aspects mentioned earlier, leading to a more robust and thoughtful conclusion.

The COT technique results in a more thorough and nuanced exploration of the query, enhancing the reliability and depth of the analysis. It mirrors the thought process a human expert might follow, making it particularly useful for complex analytical tasks in fields like finance.



III. Advanced Data Pipelines and the Role of RAG in Enterprise AI
