Revisiting the sudden changes and volatility persistence in European capital markets: Some empirical evidence

Sudden changes in volatility: The case of five central European stock markets

This paper investigates sudden changes in volatility in the stock markets of new European Union (EU) members by utilizing the iterated cumulative sums of squares (ICSS) algorithm. Using weekly data over the sample period 1994–2006, the time period of sudden change in variance of returns and the length of this variance shift are detected. A sudden change in volatility seems to arise from the evo...

Volatility spillovers across equity markets: European evidence

This paper examines the issue of volatility spillovers across the three largest European stock markets, namely London, Frankfurt and Paris. The Exponential Generalized Autoregressive Conditional Heteroscedasticity model is used to capture potential asymmetric effects of innovations on volatility. During the period from 01/01/84 to 07/12/93, reciprocal spillovers are found to exist between Londo...

Modeling sudden volatility changes: Evidence from Japanese and Korean stock markets

In this study, we have investigated sudden changes in volatility and re-examined the persistence of volatility in Japanese and Korean stock markets during 1986–2008. Using the iterated cumulative sums of squares (ICSS) algorithm, we have determined that the identification of sudden changes is generally associated with global financial and political events. We have also demonstrated that control...

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...
