Aloosh, Arash; Ouzan, Samuel; Hussain Shahzad, Syed Jawad - 2022
This study examines the price explosiveness of stocks whose purchase Robinhood restricted during the GameStop episode. We find that those “meme stocks” comprise multiple periods of explosiveness, indicating that they are unlikely to be an epiphenomenon. We also document evidence of price...

Multiple Changes in Persistence vs. Explosive Behaviour : The Dotcom Bubble
de Medeiros, Otavio Ribeiro - 2012
Based on a method developed by Laybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the Nasdaq stocks. The results confirm the existence of the so-called Dotcom bubble around the last turn of the century...

Cointegration Test with Stationary Covariates and the CDS-Bond Basis During the Financial Crisis
Wu, Jason - 2011
This paper proposes a residual based cointegration test with improved power. Based on the idea of Hansen (1995) and Elliott & Jansson (2003) in the unit root testing case, stationary covariates are used to improve the power of the residual based Augmented Dickey Fuller (ADF) test. The asymptotic...

Testing for single bubble episode in the Nigerian stock market : an empirical investigation
Iliyasu, Jamilu; Saba, Ndayezhin D. - In: CBN journal of applied statistics 10 (2019) 1, pp. 29-49
This study evaluates a single bubble episode in the Nigerian Stock Exchange (NSE) by utilizing monthly data on nominal and real all-share index (ASI) from January 2010 to December 2017. Analysis of data based on Sup Augmented Dickey-Fuller (SADF) test for bubble detection suggests non-existence...

Stock Returns Declustering Under Time Dependent Hölder Exponent
Bianchi, Sergio - 2011
Two of the most important stylized facts well-known in finance relate to the non-Gaussian distribution and to the volatility clustering of stock returns. In this paper, we show that a new class of stochastic processes – called Multifractional Processes with Random Exponent (MPRE) – can...

Seasonal long memory in intraday volatility and trading volume of Dow Jones stocks
Voges, Michelle; Leschinski, Christian; Sibbertsen, Philipp - 2017 - This version: June 28, 2017
It is well known that intraday volatilities and trading volumes exhibit strong seasonal features. These seasonalities are usually modeled using dummy variables or deterministic functions. Here, we propose a test for seasonal long memory with a known frequency. Using this test, we show that...

Stock Return Predictability and Variance Risk Premia : Statistical Inference and International Evidence
Bollerslev, Tim - 2012
Recent empirical evidence suggests that the variance risk premium predicts aggregate stock market returns. We demonstrate that statistical finite sample biases cannot “explain” this apparent predictability. Further corroborating the existing evidence of the U.S., we show that country...
