Detect market regimes using Hybrid ML with HMM, K-Means, and PCA in Python

intermediate Published 12 Apr 2026
Action Steps
  1. Import necessary libraries using pip install numpy pandas matplotlib scikit-learn
  2. Load historical data for SPY, IWM, HYG, LQD, VIX using Yahoo Finance or Quandl
  3. Apply PCA to reduce dimensionality and improve model performance
  4. Implement Hidden Markov Model to identify regime transitions
  5. Use K-Means clustering to group regimes and visualize results
  6. Evaluate model performance using metrics such as accuracy and F1-score
