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

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

How to make a simple algorithmic trading strategy with a 472% return using Python.

A thread. 🧵 Image
This strategy takes advantage of "flow effects", which is how certain points in time influence the value of an asset.

This strategy uses a simple temporal shift to determine when trades should exit relative to their entry for monthly boundary conditions. Image
The signals for when to go short, when to cover shorts, when to go long, and when to close longs are all linked to these recurring monthly cycles.

This periodic "flow" of signals—month-in, month-out—creates a systematic pattern. Image

Top 10 Algorithmic Trading Strategies (and how they work) 🧵 Image
1. Pairs Trading

Trades two correlated instruments simultaneously. It goes long on one asset and short on the other to profit from deviations from their historical relationship, expecting the correlation to eventually resume.
2. Scalping

Involves making numerous small trades to capture minimal price differences over a short time. For example, tape reading is used to analyze order flow and timing, enabling scalpers to profit from very brief price fluctuations.
