%0 Journal Article %T An Application of Correlation Clustering to Portfolio Diversification %A Hannah Cheng Juan Zhan %A William Rea %A Alethea Rea %J Quantitative Finance %D 2015 %I arXiv %X This paper presents a novel application of a clustering algorithm developed for constructing a phylogenetic network to the correlation matrix for 126 stocks listed on the Shanghai A Stock Market. We show that by visualizing the correlation matrix using a Neighbor-Net network and using the circular ordering produced during the construction of the network we can reduce the risk of a diversified portfolio compared with random or industry group based selection methods in times of market increase. %U http://arxiv.org/abs/1511.07945v1
