Single Stock Futures

This paper investigated the price discovery and asymmetric volatility spillover effects between single stock futures and spot markets. For this purpose we employ 4 largest Korean financial holding companies's daily data covering the period from May 7, 2008 to the end of December, 2010. We introduce the Nelson (1991)'s Exponential GARCH models and the major empirical results are as follows; First, according to Johansen co-integration test, there is a long run relationship between the level variables of 4 financial holding companies' futures and cash markets. Second, based on Granger causality test, 3 financial holding companies's futures contracts among 4 have an impact on the spot returns at a significant level. Third, financial holding companies' futures and spot markets are influenced at 10% to 27% by previous price changes of each market. Fourth, there is a asymmetric volatility spillover effects in 4 financial holding companies futures markets. From this result we infer that individual futures and spot markets in banking area are more sensitive to bad news than good news. These empirical results are consistent with the those of Sakthivel and Kamaiah (2010), Chan et al.(1991), Lien and Tse (2000), Yang et al.(2001) and from these results we infer that 4 single stock futures market are more efficient than those of there spot markets.

Asymmetric Volatility

This paper investigates the price discovery, volatility spillover, and asymmetric volatility spillover effects between the KOSPI 200 market and its futures contracts market. The investigation was performed using the VECM-DCC-GARCH approach. In the case of returns, we found a significant unidirectional information flow from the futures market to the spot market; this implies that the KOSPI 200 futures market plays an important role on the price discovery in the spot market. In addition, we found a strong bi-directional casualty involving the volatility interaction between the spot and futures markets; this implies that market volatility originating in the spot market will influence the volatility of the futures market and vice versa. We also found strong asymmetric volatility spillover effects between the two markets.

Purpose With a substantial return and volatility characteristic of Bitcoin, which may be seen as a new category of investment assets, better understanding of the nature of return and volatility spillover can help investors and regulators in achieving the potential goal from portfolio diversification. The paper aims to discuss these issues. Design/methodology/approach This paper explores the return and volatility transmission between the Bitcoin, as the largest cryptocurrency, and other traditional asset classes, namely stock, bond and currencies from the standpoint of Turkey over the period July, 2010–June, 2018 using the newly developed multivariate econometric technique, VAR–GARCH, in mean framework with the BEKK representation. Findings The empirical results reveal the existence of the positive unilateral return spillovers from the bond market to Bitcoin market. Regarding the results of shock and volatility spillovers, there exists strong evidence of bidirectional cross-market shock and volatility spillover effects between Bitcoin and all other financial asset classes, except US Dollar exchange rate. Originality/value The important extention is the adoption of a newly developed multivariate econometric technique, VAR–GARCH, in mean framework with the BEKK representation, proposed by Engle and Kroner (1995), which is employed for the first time specifically to examine the extent of integration in terms of volatility and return between Bitcoin and key asset classes. Second, Bitcoin has experienced a rapid growth since around a decade and a number of investors are showing interest in its potential as an integrative part of portfolio diversification. The information provided by empirical results gives empirical bases from which to address topics concerning hedging purposes and optimal portfolio allocation. It is also increasingly important to analyze the current behavior of Bitcoin in relation to other assets to provide policy makers and regulatory bodies with guidance on the role of the Bitcoin as an investment asset in Turkey. Thus, this is the first serious attempt at exploring the potential for Bitcoin to offer diversification opportunities in the context of Turkey.
