Portfolio-Analytics-Lab: Professional Risk & Performance Engine
Hello World! 
I’m excited to share my Portfolio-Analytics-Lab, an interactive application designed to help investors reconstruct, evaluate, and understand their portfolios through a professional-grade analytics pipeline.

Accurate Measurement: Measure performance correctly (Time-Weighted vs Money-Weighted).
-
Alpha Identification: Pinpoint exactly where your returns are coming from.
