Asymmetric volatility

This study aims to investigate the interactions, volatility spillovers and smooth transition effects between stock and foreign exchange markets in emerging versus developed countries by the Smooth Transition Vector Error Correction-Smooth Transition GARCH with Dynamic Conditional Correlation model (STVESTGARCH-DCC). The empirical results yield several findings. Firstly, boom stock markets in emerging countries will trigger their domestic currency appreciation, while prosperous stock markets in developed countries result in currency depreciation.

In this paper, employ asymmetric multivariate GARCH approaches to examine their performance on the volatility interactions between global crude oil prices and seven major stock market indices. Insofar as volatility spillover across these markets is a crucial element for portfolio diversification and risk management, we also examine the optimal weights and hedge ratios for oil-stock portfolio holdings with respect to the results.

This paper studies the volatility of Maersk’s stock return series. Data is collected for the period of more than 16 years, with more than 4000 observations obtained to secure the stability of model estimation. It is worth noticed that the largest volatility occurs during the global finance crisis. The author finds that ARCH effects exist in the series. Thus, GARCH models are employed for further estimation. While GARCH (1,1) helps remove all ARCH effects of the process, TGARCH (1,1) suggests that asymmetric effects exist in the series.

This study investigates models for overnight interest rate volatility in Turkey and USA using the Asymmetric GARCH models and determines the best forecasting volatility models. These models are then completed with the use of out of sample forecasting. The best forecasting volatility models were chosen as the best forecasting is done with taking importance of the choosing criteria.

This study investigates (i) the impact of first- and second-moment exchange rate exposure on individual firm value and the stock return volatility underlying exchange rate fluctuation, (ii) the time-varying exchange rate exposure following the 1997 Asian financial turmoil and the global financial crisis which started in 2007. We find a high percentage of exposed firms before the two crises but if this percentage decreases dramatically after, the exposure level is much larger. The two crises affect also the asymmetric profile of the firms and volatilities.

Utilizing forty-five years of daily London gold price fixes, this paper finds the presence of dual long-memory processes in the 10:30am fix and the 3:00pm price fix utilizing ARFIMA-FIGARCH and ARFIMA-FIEGARCH models, respectively. This research proves that the return and volatility of the London Gold price fixes have predictable structures and does not conform to the weakform efficient assumption of Fama (1970). This study also suggests that the London gold price fixes do not exhibit leverage effects and asymmetric volatility response properties.

This study aims to provide an empirical analysis of the return-volume and volatility-volume linkages, using both market- and sector-level data from the emerging equity market of Qatar. The OLS and VAR modelling approaches are employed to explore the contemporaneous and dynamic relations, respectively, between index returns and trading volume, while the volatility-volume relation is examined using an EGARCH-X(1,1) model. The results suggest a positive contemporaneous return-volume relation across almost all sectors, and this relation is found to be asymmetric.

This paper investigates the implementation of asymmetric models and skewed distributions when managing market risk using the Value-at-Risk. The comparative analysis of the VaR estimations is executed by consideration of the time dynamics and the sequence of potential violation of the model.

In light of increasing global financial market volatilities, firms are encountering a more uncertain cash flow than ever. To avoid missing investment opportunities, firms will hold cash as a precautionary measure. We investigate whether cash holdings in Taiwanese firms is indeed driven by the uncertainty of cash flow. Our empirical results confirm that uncertainty of cash flow is the most important factor that explains why firms hold cash.

Known as one of the key risk measures, volatility has attracted the interest of many researchers. These aim, in particular, to estimate and explain its evolution over time. Several results reveal that volatility is characterized, among other things, by its asymmetric variations (Chordia and Goyal 2006, Mele 2007, Shamila et al 2009, etc.). In this article, we seek to analyze and predict the volatility of the BRVM through these two indices. The data used are daily and start from the period from 04 January 2010 to 25 May 2016.

This paper aims to study the asymmetric relation between stock returns and volatility in ASEAN-6 stock markets by applying EGARCH model to the daily ASEAN-6 returns stock markets over the period of July 31, 2000 to April 1, 2015. Our results also showed that conditional volatility react to good and bad news asymmetrically.
