Stock Correlation

This is a well-structured financial analysis tool that finds stocks that move together using historical price data from Yahoo Finance. It routes between four sub-skills depending on what you ask: discovering correlated peers for a single ticker, analyzing the relationship between two specific stocks, clustering groups of tickers, or examining time-varying correlations. The peer discovery is thoughtfully designed to build universes dynamically using yfinance screeners rather than hardcoded lists, and it pulls from same-industry, sector, and adjacent thematic groups. Each sub-skill returns practical metrics like Pearson correlation, beta, R-squared, and spread z-scores with clear interpretation guides. Good for research and pair trading ideas, though the disclaimer is right that this is educational only.
