Introduction
To ensure the effectiveness and validity of the AI-driven stock purchase model under a value investing paradigm, a structured evaluation methodology will be employed. This section outlines the key approaches for assessing and evaluating study outcomes.
Identified Project Outcomes
- NLP-Based Market Sentiment Analysis: A Natural Language Processing system that analyzes financial news, social media, and earnings transcripts to assess negative stock market sentiment. Such sentiment often leads to depressed stock prices, providing excellent buying opportunities. A fundamental principle of value investing is to purchase securities at discounted prices, as investment returns are inversely proportional to the price paid (Buffett & Clark, 2011).
- Financial Performance Assessment Tool: A system that assesses key financial yardsticks to identify businesses with excellent performance, ensuring investments are backed by superior business metrics. Analyzing financial statements is numerically intensive but indispensable for understanding company performance (Greenwald et al., 2020).
- NLP-Based Competitive Advantage Identification: A Natural Language Processing system that analyzes qualitative data, business and trade press, analyst reports, and earnings calls to detect businesses with compelling competitive advantages (e.g., brand loyalty, high switching costs, legal protections, or network effects) (Buffett & Clark, 2011).
- Integrated AI Model for Investment Insights: A module that integrates the above-mentioned value investing processes into a metric that signals whether a company is suitable for investment.
- Backtesting and Performance Benchmarking: An evaluation of the AI model’s performance by comparing it to the S&P 500 over a ten-year period (2014–2023). This process will assess the model's validity using real-world data and confirm its viability as an investing tool.
Planned Project Timescales
The planned timeline for designing, developing, and assessing the model will be from April 29, 2025, to June 23, 2025.
