Portfolio Analytics Lab

[Dame-Sky]

Hi Ranaroussi,
I don't know if this is allowed but your script inspired me to create something of my own and given your expertise, i was hoping you could give me some pointers.
This report i have embedded is where it all began for me:
Equal_Weight_Portfolio vs JSE Main Index.html

I realized that it was possible to actively trade with tools to help you make better decisions, but I realized that i needed more though.

So, 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.

🧲 What the app does:
Users can manually input transactions or bulk upload datasets using a provided template. The system then rebuilds holdings, valuations, performance attribution, and risk metrics from first principles.

🚀 Key Capabilities:

• Deep Construction: Understand exactly how your portfolio is built.
• Accurate Measurement: Measure performance correctly (Time-Weighted vs Money-Weighted).
• Alpha Identification: Pinpoint exactly where your returns are coming from.
• Risk Evaluation: Assess diversification and volatility metrics.
• Financial Intuition: Interactive tools to build a better “feel” for market structures.

🛠️ Tech Stack:

• Frontend: Streamlit
• Visuals: Plotly (Interactive) & Matplotlib (Static)
• Compute: NumPy & SciPy (Heavy-duty financial math)

I’d love to hear your thoughts or feedback on the analytics!
