概要
This skill enables Claude to perform sophisticated macro-financial analysis by establishing a leading relationship between the US Treasury yield spread (e.g., 2Y-10Y) and future relative returns of equity sectors like Nasdaq 100 (QQQ) versus Healthcare (XLV). It automates data collection from FRED and Yahoo Finance, performs lead-lag correlation scanning to find optimal prediction windows, and generates Bloomberg-style visualizations. It is particularly useful for quantitative analysts and traders seeking to validate historical macro patterns and project future sector rotations based on economic cycle expectations.
