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.

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.
volatility ranks among the most active and successful areas of research in econometrics and empirical asset pricing finance over the past three decades. this two-volume collection of papers comprises some of the most influential published works from this burgeoning literature, both classic and contemporary. topics covered include garch, stochastic and multivariate volatility models as well as forecasting, evaluation and high-frequency data. together with an original introduction by the editors, this definitive compilation presents the most important milestones and contributions that helped pave the way to today's understanding of volatility.

motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. much less has been said regarding the influence of financial news on financial markets. we propose a novel measure of collective behaviour based on financial news on the web, the news cohesiveness index (nci) and we demonstrate that the index can be used as a financial market volatility indicator. we evaluate the nci using financial documents from large web news sources on a daily basis from october 2011 to july 2013 and analyse the interplay between financial markets and finance-related news. we hypothesise that strong cohesion in financial news reflects movements in the financial markets. our results indicate that cohesiveness in financial news is highly correlated with and driven by volatility in financial markets.

a long short-term memory neural network is applied to model s&p 500 volatility, incorporating google domestic trends as indicators of the public mood and macroeconomic factors and shows strong promise for better predicting stock behavior via deep learning and neural network models. we have applied a long short-term memory neural network to model s&p 500 volatility, incorporating google domestic trends as indicators of the public mood and macroeconomic factors. in a held-out test set, our long short-term memory model gives a mean absolute percentage error of 24.2%, outperforming linear ridge/lasso and autoregressive garch benchmarks by at least 31%. this evaluation is based on an optimal observation and normalization scheme which maximizes the mutual information between domestic trends and daily volatility in the training set. our preliminary investigation shows strong promise for better predicting stock behavior via deep learning and neural network models.

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.
