this study examines the volatility of nine leading cryptocurrencies by market capitalization—bitcoin, xrp, ethereum, bitcoin cash, stellar, litecoin, tron, cardano, and iota-by using a bayesian stochastic volatility (sv) model and several garch models. we find that when we deal with extremely volatile financial data, such as cryptocurrencies, the sv model performs better than the garch family models. moreover, the forecasting errors of the sv model, compared with the garch models, tend to be more accurate as forecast time horizons are longer. this deepens our insight into volatility forecast models in the complex market of cryptocurrencies.

in this paper we use malliavin calculus techniques to obtain an expression for the short-time behavior of the at-the-money implied volatility skew for a generalization of the bates model, where the volatility does not need to be a diffusion or a markov process, as the examples in sect. 7 show. this expression depends on the derivative of the volatility in the sense of malliavin calculus.

wind power forecasting is of great significance to the safety, reliability and stability of power grid. in this study, the garch type models are employed to explore the asymmetric features of wind power time series and improved forecasting precision. benchmark symmetric curve (bsc) and asymmetric curve index (aci) are proposed as new asymmetric volatility analytical tool, and several generalized applications are presented. in the case study, the utility of the garch-type models in depicting time-varying volatility of wind power time series is demonstrated with the asymmetry effect, verified by the asymmetric parameter estimation. with benefit of the enhanced news impact curve (nic) analysis, the responses in volatility to the magnitude and the sign of shocks are emphasized. the results are all confirmed to be consistent despite varied model specifications. the case study verifies that the models considering the asymmetric effect of volatility benefit the wind power forecasting performance.

understanding the irrational sentiments of the market participants is necessary for making good investment decisions. despite the recent academic effort to examine the role of investors’ sentiments in market dynamics, there is a lack of consensus in delineating the structural aspect of market sentiments. this research is an attempt to address this gap. the study explores the role of irrational investors’ sentiments in determining stock market volatility. by employing monthly data on market-related implicit indices, we constructed an irrational sentiment index using principal component analysis. this sentiment index was modelled in the garch and granger causality framework to analyse its contribution to volatility. the results showed that irrational sentiment significantly causes excess market volatility. moreover, the study indicates that the asymmetrical aspects of an inefficient market contribute to excess volatility and returns. the findings are crucial for retail investors as well as portfolio managers seeking to make an optimum portfolio to maximise profits.

the authors examine the relation between price returns and volatility changes in the bitcoin market using a daily database denominated in us dollar. the results for the entire period provide no evidence of an asymmetric return-volatility relation in the bitcoin market. the authors test if there is a difference in the return-volatility relation before and after the price crash of 2013 and show a significant inverse relation between past shocks and volatility before the crash and no significant relation after. this finding shows that, prior to the price crash of december 2013, positive shocks increased the conditional volatility more than negative shocks. this inverted asymmetric reaction of bitcoin to positive and negative shocks is contrary to what one observes in equities. as leverage effect and volatility feedback do not adequately explain this reaction, the authors propose the safe-haven effect (baur, asymmetric volatility in the gold market , 2012). they highlight the benefits of adding bitcoin to a us equity portfolio, especially in the pre-crash period. robustness analyses show, among others, a negative relation between the us implied volatility index (vix) and bitcoin volatility. those additional analyses further support the findings and provide useful information for economic actors who are interested in adding bitcoin to their equity portfolios or are curious about the capabilities of bitcoin as a financial asset.
