Construction of Minimum Spanning Trees from Financial Returns using Rank Correlation

  title={Construction of Minimum Spanning Trees from Financial Returns using Rank Correlation},
  author={Tristan Millington and Mahesan Niranjan},
The construction of minimum spanning trees (MSTs) from correlation matrices is an often used method to study relationships in the financial markets. However most of the work on this topic tends to use the Pearson correlation coefficient, which relies on the assumption of normality and can be brittle to the presence of outliers, neither of which is ideal for the study of financial returns. In this paper we study the inference of MSTs from daily US financial returns using Pearson and two rank… Expand

Stability and similarity in financial networks—How do they change in times of turbulence?
Abstract Diversified portfolios are a key component of modern portfolio theory, based on the idea of choosing uncorrelated or unrelated stocks to minimize risk. With this in mind, we use networks toExpand


Comparing minimum spanning trees of the Italian stock market using returns and volumes
We have built the network of the top 100 Italian quoted companies in the decade 2001–2011 using four different methods, comparing the resulting minimum spanning trees for methods and industryExpand
Clustering and information in correlation based financial networks
Abstract.Networks of companies can be constructed by using return correlations. A crucial issue in this approach is to select the relevant correlations from the correlation matrix. In order to studyExpand
Spanning Trees and bootstrap Reliability Estimation in Correlation-Based Networks
It is shown that the Average Linkage Minimum Spanning Tree recognizes economic sectors and sub-sectors as communities in the network slightly better than the Minimumspanning Tree and the average reliability of links is slightly greater than the average unreliable links in the average linkage minimum Spanning tree.

Partial correlation financial networks
This paper constructs both correlation and partial correlation networks from S&P500 returns and shows that the partial correlation Networks have a smaller and much less variable intensity than the correlation networks but in fact are less stable. Expand
Dynamics of market correlations: taxonomy and portfolio analysis.
The time dependence of the recently introduced minimum spanning tree description of correlations between stocks, called the "asset tree", has been studied in order to reflect the financial market taxonomy and the basic structure of the tree topology is very robust with respect to time. Expand
Quantifying Influence in Financial Markets via Partial Correlation Network Inference
By measuring the centrality of the various sectors in the network it is found that the financial sector is regarded as the most important for the majority of the dataset. Expand
Degree stability of a minimum spanning tree of price return and volatility
We investigate the time series of the degree of minimum spanning trees (MSTs) obtained by using a correlation-based clustering procedure which starts from (i) asset return and (ii) volatility timeExpand
Network analysis of a financial market based on genuine correlation and threshold method
This paper uses Random Matrix Theory (RMT) notion for specifying the largest eigenvector of correlation matrix as the market mode of stock network and shows that this network follows a power-law model in certain intervals. Expand
Bootstrap validation of links of a minimum spanning tree
Abstract We describe two different bootstrap methods applied to the detection of a minimum spanning tree obtained from a set of multivariate variables. We show that two different bootstrap proceduresExpand
Sector analysis for a FTSE portfolio of stocks
Using a portfolio of stocks from the London Stock Exchange FTSE100 index (FTSE), we study both the time dependence of their correlations and the normalized tree length of the associated minimalExpand
