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 ...
Hierarchical Risk ParityTail DependenceWe investigate portfolio diversification strategies based on hierarchical clustering. These hierarchical risk parity strategies use graph theory and unsupervisedoi:10.2139/ssrn.3513399Lohre, HaraldRother, CarstenSchfer, Kilian Axel...

Further, while IVP has a higher Sharpe ratio than MPT over the testing period, remember that both of these methodologies are risk-parity portfolios. They aim to minimize risk and do not take return into account. It may be more pertinent to notice that over the testing period HRP has a 5.5...

However, TLEF combines GA and DE using a mechanical parity-interleaved approach, while HAEF intelligently selects the evolutionary path. 6.1.3 Convergence curves This subsection presents convergence curves of DFS, ID-DGA, TLEF and HAEF at \(t=0.2\) in Figures 7 and 8. These curves offer ...
By parity of reasoning, all two-segment TMs except TM15 are recognized by SVM_Ⅱ. If the test sample does not belong to the above three types of TMs, the nearest PME is directly output, which means that there are no TMs at present. It should be noted that the recognition priority of...

The results suggest that, in general, hierarchical risk parity does not report the best performance but, in some performance measures, performs equally well to other approaches. Overall, hierarchical risk parity outperforms the market index.Reis, Felipe...
