Uncertainty, volatility and the persistence norms of financial time series

نویسندگان

چکیده

Norms of Persistent Homology introduced in topological data analysis are seen as indicators system instability, analogous to the changing predictability that is captured financial market uncertainty indexes. This paper demonstrates norms from markets significant explaining uncertainty, whilst macroeconomic only explainable by volatility. Meanwhile, volatility insignificant determination when enters regression. Persistence therefore have potential a further tool asset pricing, and also means capturing signals time series beyond

Overlaying Time Scales and Persistence Estimation of Financial Volatility Data

A common finding in the empirical literature is that financial volatility exhibits high persistence, or slow mean reversion of the order of months. We present evidence that financial volatility data contains more than a single time scale. When occasional parameter changes are not accounted for in global GARCH(1,1) estimations, they lead to an estimated persistence far above the average data-gen...

Volatility, persistence, and survival in financial markets.

We study the temporal fluctuations in time-dependent stock prices (both individual and composite) as a stochastic phenomenon using general techniques and methods of nonequilibrium statistical mechanics. In particular, we analyze stock price fluctuations as a non-Markovian stochastic process using the first-passage statistical concepts of persistence and survival. We report the results of empiri...

Asset returns and volatility clustering in financial time series

An analysis of the stylized facts in financial time series is carried out. We find that, instead of the heavy tails in asset return distributions, the slow decay behaviour in autocorrelation functions of absolute returns is actually directly related to the degree of clustering of large fluctuations within the financial time series. We also introduce an index to quantitatively measure the cluste...

Financial Time Series and Volatility Prediction using NoVaS Transformations

We extend earlier work on the NoVaS transformation approach introduced by Politis (2003a,b). The proposed approach is model-free and especially relevant when making forecasts in the context of model uncertainty and structural breaks. We introduce a new implied distribution in the context of NoVaS , a number of additional methods for implementing NoVaS and we examine the relative forecasting per...

Irregularity, volatility, risk, and financial market time series.

The need to assess subtle, potentially exploitable changes in serial structure is paramount in the analysis of financial data. Herein, we demonstrate the utility of approximate entropy (ApEn), a model-independent measure of sequential irregularity, toward this goal, by several distinct applications. We consider both empirical data and models, including composite indices (Standard and Poor's 500...
