Sure, I can help you with that. The Markowitz model is a portfolio optimization model that focuses on minimizing risk while maximizing returns. To implement this model in Python, you can follow the below steps:
1. Import the necessary libraries such as pandas, numpy, and matplotlib.
2. Load the historical stock price data for the assets you want to include in your portfolio.
3. Calculate the daily returns of each asset.
4. Compute the mean and covariance matrix of the returns.
5. Define the optimization objective function that minimizes the risk of the portfolio.
6. Define the constraints, which include the minimum and maximum allocation for each asset, and the sum of all allocation weights is equal to one.
7. Solve the optimization problem using a quadratic programming solver, such as cvxopt.
8. Display the optimal portfolio weights and other important metrics, such as the expected return and risk.
Hope this helps! Let me know if you have any further questions.
