In 10 lines of Python code, I can do a full portfolio optimization.

This is wild. Let me show how: Image
1. Load Python libraries

These are the python packages and functions we'll use. Image
2. Create a Maximum Sharpe Ratio Portfolio

We create a Maximum Sharpe Ratio model and then fit it on the training set.

portfolio_params are parameters passed to the Portfolio returned by the predict method. Image
3. Create a Benchmark

This is an inverse volatility portfolio that I'll compare my Max Sharpe portfolio against. Image
4. Out-Of-Sample Performance

Use Predict Method to get out-of-sample Portfolio Performance Image
5. Portfolio Composition

The visualizations from skfolio are incredible. Image
6. Cumulative Returns

In 1 line of code, we can get cumulative returns for our portfolio and benchmark. Image
7. Performance Tear Sheet

In 1 line of code, I get a comprehensive performance tear sheet to share with clients. Image

In investing, your track record is everything.

In 2 minutes, I'll uncover the secrets hedge funds use to track their portfolio performance: 🧵 Image
There are 3 main areas that smart investors care about:

1. Profits (Returns)
2. Risks
3. Drawdowns

Let's break them down using the snapshot:
1. Profitability Insights

Annual Return: 22.44%—strong growth!

CAGR: 23.78%—compounded gains over time.

MAR: 0% (minimum acceptable)—room to beat risk-free rates.

Significance level (5%) sets the risk benchmark.

How to create a Black-Litterman portfolio in Python.

A thread: 🧵 Image
1. What is Black-Litterman?

Black-Litterman starts with market equilibrium returns (from CAPM) and lets you add your views (e.g., “Tesla will outperform”).

It balances both to create optimal weights. No overfitting, just math.
2. How it works

Using skfolio in Python, you:

- Compute market returns (e.g., S&P 500).
- Add views (e.g., 5% outperformance for tech).
- Blend with confidence levels.
- Optimize weights.
