针对马科维茨CLA在二次规划中的三个问题提出了层次风险平价模型(Hierarchical Risk Parity -- HRP)。虽然同样是基于协方差矩阵构建的分散化投资组合,HRP不仅不需要协方差矩阵可逆,甚至能在退化或奇异协方差矩阵下构建投资组合。 【正文】 马科维茨提出了Critical Line Algorithm (CLA)算法用于非等式限制条件下的二次优...
In particular, it contrasts these techniques with several competing risk‐based allocation paradigms, such as 1/N, minimum﹙ariance, standard risk parity and diversified risk parity. The chapter introduces hierarchical risk parity (HRP) strategies based on the Pearson correlation coefficient and also ...
In this post, I walk through a step-by-step guide introducing ML techniques for efficient portfolio allocation using hierarchical risk parity (HRP). This example uses Python with RAPIDS. Choosing an algorithm for efficient financial predictions In 1952, Harry Markowitz introduced a portfolio-optimizati...

With this course, you can learn to apply the hierarchical risk parity (HRP) approach on a group of 16 stocks and compare the performance with inverse volatility weighted portfolios (IVP), equal-weighted portfolios (EWP), and critical line algorithm (CLA) techniques....
此外,虽然 IVP 在测试期间的夏普比率高于 MPT ,但请记住,这两种方法都是risk-parity组合。他们的目标是将风险降至最低,不考虑回报。值得注意的是,在测试期间, HRP 的风险为 5.5% ,而 IVP 的风险为 9.4% 。 分析速度 另一个需要分析的是运行时与 CPU 的比较。您可以使用 SciPy 、 pandas 或...

This paper presents the Hierarchical Risk Parity (HRP) model and its implementation using assets of Latin American companies listed as ADRs on the NYSE. Two portfolios are optimized: HRP and Mean-Variance (MV). The in-sample results show better performance for the HRP portfolio; however, in ...

Hierarchical Risk Parity methods address instability, concentration, and underperformance in asset allocation by taking advantage of machine learning techniques to build a diversified portfolio. HRP methods produce a hierarchical structure to the correlation between assets by means of tree clustering that ...
