Uncertainty, volatility and the persistence norms of financial time series

  title={Uncertainty, volatility and the persistence norms of financial time series},
  author={Simon Rudkin and Wanling Qiu and Pawel Dlotko},
Norms of Persistent Homology introduced in topological data analysis are seen as indicators of system instability, analogous to the changing predictability that is captured in financial market uncertainty indexes. This paper demonstrates norms from the financial markets are significant in explaining financial uncertainty, whilst macroeconomic uncertainty is only explainable by market volatility. Meanwhile, volatility is insignificant in the determination of norms when uncertainty enters the…

Is economic uncertainty priced in the cross-section of stock returns?
We investigate the role of economic uncertainty in the cross-sectional pricing of individual stocks and equity portfolios. We estimate stock exposure to an economic uncertainty index and show that
The Macroeconomic Uncertainty Premium in the Corporate Bond Market
We examine the role of macroeconomic uncertainty in the cross-section of corporate bonds and find a significant uncertainty premium for both investment-grade (0.40% per month) and
Chaos and Nonlinear Dynamics: Application to Financial Markets
After the stock market crash of October 19, 1987, interest in nonlinear dynamics, especially deterministic chaotic dynamics, has increased in both the financial press and the academic literature.
Time-Resolved Topological Data Analysis of Market Instabilities
Approaching a ‘tipping point’ in natural and social systems is often preceded by a growing variability and rising auto and cross-correlation in observed time series. This behavior may become
Which uncertainty measures matter for the cross-section of stock returns?
Abstract Using recently developed various economic uncertainty measures, we provide a compar- ison of their pricing power for the cross-section of stock returns during the most recent period. We
Topological Data Analysis of Financial Time Series: Landscapes of Crashes
The study suggests that TDA provides a new type of econometric analysis, which goes beyond the standard statistical measures, and can be used to detect early warning signals of imminent market crashes.
Topological data analysis in investment decisions
An application of TDA in Enhanced Indexing (EI) that aims to build a portfolio of fewer assets than that in the index to outperform the latter is explored and it is shown that the proposed strategy delivers superior performance on several measures, including excess mean returns from the benchmark index and tail reward-risk ratios than some of the existing models of EI in the literature.
A Simple, Positive Semi-Definite, Heteroskedasticity and Autocorrelationconsistent Covariance Matrix
This paper describes a simple method of calculating a heteroskedasticity and autocorrelation consistent covariance matrix that is positive semi-definite by construction. It also establishes
Clustering and classification of time series using topological data analysis with applications to finance
RF-TDA is seen to perform quite well in the two experiments based on real-life stock-price data, which implies that the topological features of the time series of stock prices in the different sectors are not identical and have distinctive features that can be discerned through the use of TDA.
The Persistence Landscape and Some of Its Properties
Persistence landscapes map persistence diagrams into a function space, which may often be taken to be a Banach space or even a Hilbert space. In the latter case, it is a feature map and there is an
