About
This skill enables Claude to perform sophisticated equity performance analysis by calculating cumulative returns for specific stocks or entire indices. It uses a standardized methodology with a hardcoded S&P 500 benchmark to ensure consistent alpha measurement across all comparisons. The skill supports four distinct analysis scenarios, including specific year reviews and year-to-date tracking, and provides high-quality Bloomberg-style visualizations. It is particularly useful for financial analysts and developers who need to quickly rank index components or compare portfolio assets against the broader market directly within their workflow.
