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 ...
This example will walk you through the steps to build an asset allocation strategy based on Hierarchical Risk Parity (HRP). You will: Learn how to use statistics and machine learning techniques to cluster assets into a hierarchical tree structure. Understand how to develop allocation strategies ...

Drawing on a recent contribution to the literature on risk budgeting (RB), the author investigates an RB approach based on the filtered similarity matrix generated by hierarchical clustering. Like the hierarchical risk parity (HRP) approaches, the resulting RB approach, which the author calls hierarc...
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 ...
