In recent years, advancements in machine learning (ML) and deep learning (DL) technologies in the financial markets have significantly impacted the efficiency and performance of algorithmic trading. In particular, ML-based trading strategies enable better investment decisions through the automation of data analysis. This article will Explore & Explain the HRP (Hierarchical Risk Parity) backtesting method based on ML trading strategies.
Basic Concepts of Machine Learning and Deep Learning
1.1 Overview of Machine Learning
Machine learning is a field of artificial intelligence (AI) that empowers computers to learn from data and make predictions. ML algorithms are primarily used for pattern recognition and predictive modeling, allowing them to estimate future outcomes based on past data.
1.2 Overview of Deep Learning
Deep learning is a subset of machine learning that utilizes artificial neural networks to analyze data. It demonstrates exceptional performance in analyzing unstructured data (e.g., images, text) and is being utilized in various ways in the financial markets recently.
What is HRP Backtesting?
The HRP (Hierarchical Risk Parity) strategy is a method that considers the correlations between asset classes to diversify risk. This approach is known for minimizing portfolio risk while maximizing returns. HRP generates a hierarchy based on the similarities between assets and optimizes the asset proportions in each layer to manage risk.
2.1 How HRP Works
HRP operates in the following steps:
- Analyzing the correlations among assets.
- Creating a hierarchy by clustering similar assets based on the correlation matrix.
- Optimizing the asset weights in each cluster to spread the risk.
2.2 Advantages of HRP
The main advantages of HRP are as follows:
- It balances maximizing returns with optimizing risk.
- It provides a systematic understanding of relationships among assets.
- Portfolio adjustments are easier depending on market conditions.
Establishing ML Trading Strategies
Establishing an ML trading strategy involves data collection, model selection, and backtesting phases. The following steps can be followed to develop an ML trading strategy:
3.1 Data Collection
Diverse types of data are required to build an efficient ML model. Stock prices, trading volumes, technical indicators, and economic indicators need to be collected. Data collection can primarily be performed through APIs or crawling techniques.
3.2 Data Preprocessing
The collected data is preprocessed to convert it into a suitable format for the model. Major preprocessing steps include quality checks, handling missing values, and scaling.
3.3 Model Selection
The most suitable model must be selected from several machine learning models. Commonly used models include regression, decision trees, random forests, and neural networks. Optimal performance can be achieved through hyperparameter tuning for each model.
Performing HRP Backtesting
HRP backtesting evaluates the model’s performance based on historical data. This consists of the following steps:
4.1 Setting Up the Backtest Environment
Set up the necessary libraries and tools for backtesting. In Python, libraries such as Pandas, NumPy, Matplotlib, and Scikit-learn are commonly used.
4.2 Portfolio Construction
Construct the portfolio based on the HRP model. Calculate the weights of each asset and measure the overall portfolio risk.
4.3 Performance Evaluation
Evaluate the performance based on the backtesting results. Key metrics include the Sharpe ratio, maximum drawdown, and annualized return. These metrics can help verify the effectiveness of the trading strategy.
Case Study: Implementation of ML-Based HRP Backtesting
