Modern Portfolio Theory Optimizer

This project is a Python implementation of Modern Portfolio Theory (MPT) to optimize a portfolio of stocks using historical data. The goal is to maximize the Sharpe ratio, which represents the risk-adjusted return of the portfolio.

Methodologies

Two separate methodologies are presented:

  • using Scipy optimizer
  • using a MonteCarlo simulation across 100,000 samples

Features

  • Fetch stock price data using yfinance library
  • Calculate daily returns, mean returns, and covariance matrix
  • Optimize the portfolio by maximizing the Sharpe ratio
  • Display individual stock performance, optimized portfolio weights, and overall portfolio performance

Dependencies

  • numpy
  • pandas
  • yfinance
  • datetime
  • scipy

To install the dependencies, run:

pip install numpy pandas yfinance datetime scipy

Usage

  1. Define the stocks in your portfolio by modifying the stocks list:

stocks = ['BHP.AX', 'BXB.AX', 'CSL.AX', 'MQG.AX', 'NAB.AX', 'RIO.AX', 'RMD.AX', 'SHL.AX', 'TCL.AX', 'WDS.AX', 'WTC.AX', 'TNE.AX', 'TLX.AX', 'APA.AX', 'TLS.AX']

  1. Set the time period for the analysis by modifying the start_date and end_date variables:

end_date = datetime.datetime.now() start_date = end_date - datetime.timedelta(days=180)

  1. Run the script to fetch stock price data, calculate returns and optimize the portfolio:

python mpt_optimizer.py

  1. The script will display the individual stock performance, optimized portfolio weights, and overall portfolio performance, including expected return, volatility, and Sharpe ratio.
