Forecasting the variability of stock index returns with the multifractal random walk model for realized volatilities
Sattarhoff, Cristina; Lux, Thomas - 2021
We adapt the multifractal random walk model by Bacry et al. (2001) to realized volatilities (denoted RV-MRW) and take stock of recent theoretical insights on this model in Duchon et al. (2012) to derive forecasts of financial volatility. Moreover, we propose a new extension of the binomial...

Expected lifetime range ratio to find mean reversion : evidence from Indian stock market
Shaik, Muneer; Maheswaran, S. - In: Cogent economics & finance 6 (2018) 1, pp. 1-23
We use the expected lifetime range (ELR) ratio based on the extreme values of asset prices to detect the presence of mean reversion in stock returns. We find that the actual cross-sectional average of the ELR ratio is significantly less than its bootstrap means, thereby indicating a considerable...

The modeling of earnings per share of Polish companies for the post-financial crisis period using random walk and ARIMA models
Kuryłek, Wojciech - In: Journal of banking and financial economics 19 (2023) 1, pp. 26-43
The proper forecasting of listed companies' earnings is crucial for their appropriate pricing. This paper compares forecast errors of different univariate time-series models applied for the earnings per share (EPS) data for Polish companies from the period between the last financial crisis of...

Intrinsic Bubbles and Fat Tails in Stock Prices : A Note
Bidarkota, Prasad V. - 2019
dividend stream is modeled as a random walk with innovations drawn from the family of stable distributions. We derive an exact …-driven intrinsic bubbles to explain the observed variation in annual U.S. stock prices. We compare results obtained in this setting …

Intrinsic Bubbles in Stock Prices Under Persistent Dividend Growth Rates
Awwal, Faisal M. - 2019
We extend the constant discount factor model with intrinsic bubbles developed in Froot and Obstfeld (1991) to account … for serial correlation in dividend growth rates. We derive an exact analytical expression for both the present value stock … price and an intrinsic bubble component when dividend growth rates evolve as a Gaussian first-order autoregressive process …

Multivariate variance ratio statistics
Hong, Seok Young; Linton, Oliver; Zhang, Hui Jun - 2014
We propose several multivariate variance ratio statistics. We derive the asymptotic distribution of the statistics and scalar functions thereof under the null hypothesis that returns are unpredictable after a constant mean adjustment (i.e., under the Efficient Market Hypothesis). We do not...
