SharpeSense

SharpeSense is a web app (with optional desktop CSV uploader) that calculates and explains risk-adjusted performance for real portfolios, not just toy examples. Users connect broker exports or upload statements, map holdings, and get standardized metrics: Sharpe, Sortino, Calmar, max drawdown, rolling volatility, downside deviation, and factor-adjusted alpha. The app flags misleading results (short histories, regime changes, illiquid assets, stale pricing) and shows confidence bands so users don’t over-trust a single ratio. It also benchmarks against relevant indices and a simple risk-parity baseline, then generates a short “what changed” report for monthly reviews. This is a combination traditional + AI app: traditional analytics for accuracy, AI for plain-English explanations, anomaly detection, and automated commentary. It’s built for investors who want honest performance attribution without paying institutional platform prices.
