Dynamic correlations and volatility linkages between stocks and sukuk: evidence from international markets

An understanding of volatility and co-movements in financial markets is important for portfolio allocation and risk management practices. The current financial crisis caused a shrinkage in values of most assets, an increased volatility and a threat to the survival of several institutional investors. Managing risks and returns within the classic portfolio theory, when correlations across securities soar, is increasingly challenging. In this paper, we investigate the volatility behavior and the co-movements between sukuk and international stock indexes. Symmetric multivariate GARCH models with dynamic conditional correlations (DCC) were estimated under student-t distribution. We provide evidence of high correlations between sukuk and US and EU stock markets, without finding the well-known flight to quality behavior affecting Islamic bonds. We also show that volatility linkages between sukuk and regional market indexes are higher during financial crisis. We argue that investors could obtain diversification benefits including sukuk in a well \u2013diversified equity portfolio, given their lower volatility compared to equity. But higher volatility linkages and dynamic correlations during financial crises show that they are hybrid instruments between bonds and equity. Our findings are relevant for institutional investors and asset managers, that include Islamic bonds in a diversified portfolio

The Korea discount and chaebols

Finance practitioners frequently claim that stocks of Korean firms are undervalued and trade at a discount relative to foreign firms. This phenomenon is commonly called «the Korea discount». It is based on anecdotal evidence comparing either the price- earnings ratios of different market indexes or those of different individual stocks. This paper provides empirical evidence on the existence of such a discount using a large sample of stocks from 28 countries over the period 2002-2016. We find that Korean stocks have significantly lower price-earnings ratios than their global peers. We also investigate the role of large business groups called chaebols, which are often considered to be the main cause of the discount because of their poor corporate governance. Our findings show that it is not the case
