1. AI-Powered Stock Screeners to Discover Undervalued Opportunities

Introduction
Traditional screeners apply static filters—P/E ratios, market caps, dividend yields. AI-powered screeners go further, learning from historical patterns to identify stocks with hidden upside.

Core Components

• Data Aggregation: Gather fundamentals (income statements, balance sheets), price histories, analyst estimates, and sentiment data from news and social media.

• Feature Engineering: Construct composite indicators such as momentum‐adjusted growth scores and sentiment‐volume deltas.

• Model Training: Use supervised algorithms (Random Forest, XGBoost) labeled by past outperformance (e.g., top decile returns) to learn feature importances.

• Real-Time Scoring: Score thousands of tickers daily and flag top candidates.

Step-by-Step Implementation

1. Data Collection: Use APIs (Alpha Vantage, IEX Cloud) to fetch 5+ years of daily OHLCV and quarterly fundamentals.

2. Feature Creation: Compute rolling revenue momentum, analyst‐revision differentials, and sentiment shifts with Python’s pandas and NLP libraries.

3. Modeling: Split data chronologically—train on 2015–2019, validate on 2020–2021; fine‐tune hyperparameters with grid search.

4. Backtesting: Simulate a long‐only portfolio of top 5% scored stocks, include realistic slippage and commissions.

5. Deployment: Wrap the pipeline in Docker; schedule daily runs with a cron job and generate an alert list.

Example Outcome
An AI screener identified a small-cap semiconductor stock five quarters before upgrades, yielding a 60% gain in six months.

Conclusion
By leveraging machine learning, you can uncover non‐obvious value and momentum signals that traditional screeners miss—turning data overload into actionable trade ideas.
