19 min readSep 8, 2024

The realm of algorithmic trading holds immense allure for those seeking to harness the power of data and computation to navigate the complexities of financial markets. At the heart of successful trading strategies lies portfolio optimization — the art and science of constructing a portfolio of assets that balances risk and return to maximize investment outcomes. While traditional optimization techniques often falter in the face of market noise and ever-changing dynamics, genetic algorithms emerge as a robust and adaptable solution.

This tutorial will guide you through the fascinating world of genetic algorithms, demonstrating how this powerful optimization technique, inspired by natural selection, can be applied to build superior investment portfolios. We will demystify the core concepts of genetic algorithms — chromosomes, fitness functions, selection, crossover and mutation — and empower you to implement them in Python.
