Eigen-entropy measure to study phase separation in market behavior

One of the spectacular examples of a complex system is the financial market, which displays rich correlation structures among price returns of different assets. The eigenvalue decomposition of a correlation matrix into partial correlations - market, group and random modes, enables identification of dominant stocks or "influential leaders" and sectors or "communities". The correlation-based network of leaders and communities changes with time, especially during market events like crashes… Expand

The observation on the resemblance of volatility of fluctuations of daily novel coronavirus related number of deaths to the daily stock exchange returns suggests the applicability of a recently proposed temporal correlation-based network framework applied on financial markets. Expand

Structural Entropy: Monitoring Correlation-Based Networks Over Time With Application To Financial Markets
A new measure, “Structural Entropy”, is proposed, which relies on the finer-grained network communities (in contrast to the network’s connected components), and takes into consideration both the number of communities and their sizes, generating a single representative value. 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
Community detection for correlation matrices
This work introduces, via a consistent redefinition of null models based on random matrix theory, the appropriate correlation-based counterparts of the most popular community detection techniques, and can filter out both unit-specific noise and system-wide dependencies, and the resulting communities are internally correlated and mutually anti-correlated.

This article and the companion paper aim at reviewing recent empirical and theoretical developments usually grouped under the term Econophysics. Since the name was coined in 1995 by merging the wordsExpand
Statistical mechanics of complex networks
A simple model based on these two principles was able to reproduce the power-law degree distribution of real networks, indicating a heterogeneous topology in which the majority of the nodes have a small degree, but there is a significant fraction of highly connected nodes that play an important role in the connectivity of the network.

This article proposes a method for detecting communities, built around the idea of using centrality indices to find community boundaries, and tests it on computer-generated and real-world graphs whose community structure is already known and finds that the method detects this known structure with high sensitivity and reliability.

Topology of correlation-based minimal spanning trees in real and model markets.
The empirical tree obtained from a large group of stocks traded at the New York Stock Exchange during a 12-year trading period is found to have features of a complex network that cannot be reproduced by a random market model and by the widespread one-factor model. Expand
