The world stock markets under geopolitical risks: Dependence structure

This paper reveals joint stochastic behaviours of the world’s stock markets and geopolitical risk by a copula approach for the 37 world’s stock markets over the period of June 1997 to December 2017. The various bivariate copulas show the different degrees of tail dependences and rank correlations. The differences between overall geopolitical risk index and action‐related geopolitical risk index lie in the higher tail dependence with overall geopolitical risk index, the dominancy of concordant movements of stock market indexes with overall geopolitical risk and that of discordant movements of stock market indexes with action‐related geopolitical risk index. The results illustrate that action‐related geopolitical risk is more often adversely related to the world’s stock market performances with less tail dependence.     

New evidence on hedges and safe havens for Gulf stock markets using the wavelet-based quantile

This paper examines the dynamic tail dependence structure for the Gulf equity indices, using the Dow Jones Islamic world emerging equity index and four macroeconomics factors (the three-month U.S. Treasury bill rate, the VIX index, gold prices and oil prices) under different market conditions and scale or investment horizons. We find little or insignificant dependence at the short investment horizon but strong asymmetric dependence at the middle and long investment horizons. Gold is a strong hedge and a safe haven at the short, middle and long run horizons for all Gulf markets.     

Measuring transparency and disclosure at firm-level in emerging markets

Transparency and disclosure are integral to corporate governance. In this paper, we use a new dataset to analyze Transparency & Disclosure scores (T&D score) in 19 emerging markets for 354 firms representing 70% of S&P/IFCI Index market capitalization over the 3 years ending in 2000. We analyze differences across countries, economic sectors and trend over the 3 years. We find that the Asian emerging markets and South Africa have significantly higher transparency and disclosure compared to the Latin American, Eastern European, and Middle Eastern emerging markets. The gap between the Asian emerging markets and South Africa over other emerging markets has increased over the last 3 years. We do not find any significant differences in T&D scores among economic sectors. Changes in the T&D scores over the last 3 years, however, differ by economic sectors for the 6 markets with the largest investable market capitalization and/or number of observations, viz. Brazil, Poland, South Africa, India, Thailand, and Korea. We then study the relationships between T&D scores and cross-holdings for the 6 emerging markets. For the 6 markets except Korea, correlation between cross-holdings and T&D scores is negative. For the 6 markets except South Africa, correlation between price-to-book ratios and T&D scores is positive. We conclude with a discussion on further research.     

Which is the safe haven for emerging stock markets,gold or the US dollar?

This paper examines whether gold or the US dollar is a safe haven for emerging stocks. By calculating the low-high tail dependence between markets via copulas and the downside risk gains of portfolios, we find that both gold and the US dollar can serve as a safe haven for emerging stocks; that the US dollar is better than gold in most cases, while its superiority in hedging infinitely extreme risks is weakened in the subsample of global financial crisis and the out-of-sample; and that the downside risk gains offered by the US dollar for China and Thailand are very attractive.     

Dependence of stock and commodity futures markets in China: Implications for portfolio investment

We examine the recent trends in dependence structure between the fast-growing commodity markets and the stock markets in China. We address this issue by using copula functions that allow for measuring both average and tail dependence. Our results provide evidence of low and positive correlations between these markets, suggesting that commodity futures are a desirable asset class for portfolio diversification. By comparing the market risks of alternative portfolio strategies, we show that Chinese investors can take advantage of commodity futures during different times to realize risk diversification and downside risk reduction benefits.     

Extreme Dependence under Uncertainty: an application to Stock,Currency and Oil Markets

We explore the impact of uncertainty on financial markets in the aftermath of the global financial crisis. In particular, we investigate the temporal dynamics of the dependence structure of stock, currency and oil markets in the United States using a nonparametric copula approach. Policy uncertainty is modeled via the EPU index of Baker et al. ( 2013 ). We find evidence of a pronounced extreme tail asymmetric interrelationship between the crude oil market and economic uncertainty.     

Monetary Policy,Vagabonding Liquidity and Bursting Bubbles in New and Emerging Markets: An Overinvestment View

‘Capitalism without failure is like religion without sin’. Charles Kindleberger's book Manias, Panics and Crashes points out that speculation and crises have always been present: the world economic crisis of the 20th century, the South Sea bubble in the 18th century, and the tulip mania in the first part of the 17th century. Starting with the Japanese bubble in the 1980s we take the reader on a tour through 20 years of bubbles in emerging markets and industrial countries which have recently culminated in the 2007/08 US subprime market crisis. We explain the global stock market and real estate booms based on the real and monetary overinvestment theories of Hayek, Wicksell and Schumpeter, arguing that ample liquidity supply originating in the large industrialised countries has contributed – independent from the exchange rate regime – to overinvestment cycles in new and emerging markets around the globe. The policy implication is to keep interest rates not too low for too long in response to bursting bubbles.     

Law,finance, and emerging market returns

This paper investigates how legal foundation influences the return distribution, the growth rate of market capitalization, the ratio of market capitalization to gross domestic product (GDP) and the correlation structure of emerging market indices with developed market indices. Using a sample of 24 emerging markets, we find that emerging markets from the French [civil] law systems earned higher returns, have higher correlations with the world market portfolio, higher average growth rates in market capitalization and lower average market capitalization to GDP than their English common law counterparts. Finally, most emerging markets returns are more highly correlated to the returns of developed markets with an English common law tradition. Our results suggest that diversification potential is highest with the English common law emerging markets but that the diversification benefits come at the cost of reduced returns.     

Extreme dependence and risk spillovers between oil and Islamic stock markets

This paper examines the downside and upside risk spillovers and dependence structure between five Islamic stock markets (the Islamic Market World index, Islamic indices of USA, UK, Japan and the Islamic Financials sector index) which are of paramount importance for faith-oriented investors and particpants in the oil market. The results underscore the presence of time-varying lower tail dependence between the oil and Islamic stock markets. Furthermore, we provide supportive evidence of asymmetric down- and up-side risk spillovers from oil to the Islamic stock markets and vice versa. Finally, these asymmetric risk spillovers have significantly increased after the global financial crisis.     

The kidnapping of Europe: High-order moments' transmission between developed and emerging markets

The paper proposes a semi-nonparametric methodology consistent with dynamic conditional correlations and high-order moments to jointly estimate transmissions in volatility, skewness and kurtosis in highly volatile scenarios among developed and emerging markets. As a by-product of the SNP-VSK model, we measure co-movements between conditional correlations and high-order moments, and tail dependence. Our results depict European markets as full receivers and North American and Asia-Pacific as transmitters of high-order moments' risk. The analyses also indicate that conditional correlation is positively correlated to volatility and kurtosis and negatively correlated to skewness, and that conditional kurtosis between markets is high and positive.     

Clustering in emerging equity markets

We consider pairwise tail behavior of return series for identifying the most important emerging markets clusters. Pairs of markets belonging to the same group present similar type and strength of interdependence during stressful times, represented by a common copula and a statistically equivalent measure of tail dependence. By collapsing data from d markets in to a group we overcome the difficult problem of finding their (higher dimensional) d-variate distribution. Results may help portfolio managers to deal with risk due to co-movements within clusters. We provide examples on how this can be done. Our study contributes to the discussion about the international association among stock markets during turbulent periods, and does not confirm the intuition that the observed association between extremes should be credited to linkages to leading markets. The study also confirms the importance of stock selection, particularly among the non-dominant stocks, instead of holding market-value weighed portfolios of stocks from countries within the same region.

Business innovations from emerging market countries into developed countries: Implications for multinationals from developed countries

This article addresses innovation and emerging‐market countries. Both are important topics in the business world today. The focus of this article is on the importance of innovation and market development in emerging‐market countries by Western multinational companies typically based in North America and Western Europe. The authors of this article argue that as Western multinationals innovate and develop emerging markets, this will give multinationals the opportunity not only to compete effectively in emerging markets but also to protect their home markets in developed countries. Implications for Western multinationals are discussed. © 2012 Wiley Periodicals, Inc.

Foreign Ownership Restriction and Momentum – Evidence from Emerging Markets

This study investigates the impact of foreign investors on stock price efficiency and return predictability in emerging markets. It finds that stocks fully investible for foreign investors exhibit stronger price momentum than non‐investible stocks. The difference in momentum effects between stocks with different levels of investibility cannot be fully explained by world market risk, size, turnover, or country‐specific factors. Further tests show that fully investible stocks have no post‐earnings‐announcement drift (PEAD), and their short‐term momentum reverses over a longer horizon. These results show that the stronger momentum of highly investible stocks does not appear to be driven by foreign investors' underreaction to firm‐specific information, but is more likely to be generated by their positive feedback trading.     

China's segmented stock market: An application of the conditional international capital asset pricing model

China's segmented stock market provides an opportunity to study conditional international asset pricing from multiple viewpoints—domestic and foreign. We use the multivariate GARCH-M framework of De Santis and Gérard [De Santis, G., and Gérard, B., 1998. How big is the premium for currency risk? Journal of Financial Economics 49, pp. 375–412.], but add conditional local specific risk and find global, local, and currency risk to be priced and time-varying in Chinese markets, suggesting mild segmentation for developing country markets. The time-varying price of currency risk indicates that the strict currency restrictions in China do not sufficiently reduce currency risk to stabilize the price of currency risk. We also find that the price of local risk in the Chinese A stock market is non-time-varying relative to the developed market, but time-varying relative to the emerging market. This finding implies that the Chinese A stock market is more comparable to a developed market than an emerging market. However, results on Chinese B shares show the opposite relationship: from a foreign investor's perspective, Chinese B shares are better categorized as being emerging than developed. This is further supported by an Engle–Granger cointegration test.     

Liquidity and stock returns in emerging equity markets

Using data for 27 emerging equity markets for the period January 1992 through December 1999, we document the behavior of liquidity in emerging markets. We find that stock returns in emerging countries are positively correlated with aggregate market liquidity as measured by turnover ratio, trading value and the turnover–volatility multiple. The results hold in both cross-sectional and time-series analyses, and are quite robust even after we control for world market beta, market capitalization and price-to-book ratio. The positive correlation between stock returns and market liquidity in a time-series analysis is consistent with the findings in developed markets. However, the positive correlation in a cross-sectional analysis appears to be at odds with market microstructure theory that has been empirically supported by studies on developed markets. Our findings regarding the cross-sectional relation between stock returns and liquidity is consistent with the view that emerging equity markets have a lower degree of integration with the global economy.     

Size, value and liquidity. Do They Really Matter on an Emerging Stock Market?

The paper extends the evidence on factors determining stock prices on emerging markets by focusing on the most advanced stock market in Central and Eastern Europe, the Polish market. Besides market, size and value factors, we investigate whether liquidity is a priced risk factor, addressing the hypothesis of its particular relevance in emerging markets. Our results support existing evidence for developed markets regarding market, size, and value factors. Contrary to the expectation that liquidity is a priced factor on emerging markets, we do not find evidence supporting this hypothesis. Analyzing specific market characteristics, we consider possible explanations behind these findings.     

Market integration and contagion: Evidence from Asian emerging stock and foreign exchange markets

This paper examines whether Asian emerging stock markets (India, Korea, Malaysia, Philippines, Taiwan, and Thailand) have become integrated into world capital markets since their official liberalization dates by estimating and testing a dynamic integrated international capital asset pricing model (ICAPM) in the absence of purchasing power parity (PPP) using an asymmetric multivariate GARCH(1,1)-in-Mean approach. Also examined in this paper is whether there are pure contagion effects between stock and foreign exchange markets for each Asian country during the 1997 Asian crisis. The empirical results show that first, both currency and world market risks are priced and time-varying, suggesting that an international asset pricing model under PPP and constant price of risk might give rise to model misspecification. Second, the stock markets for India, Korea, Malaysia, Philippines, and Thailand were segmented from the world capital markets before their liberalization dates, but all six markets have become fully integrated since then. Third, the market liberalization has reduced the cost of capital and price volatility for most of the countries. Finally, as for the contagion effects, strong positive impact of return shocks originating from the domestic stock market to its foreign exchange market during the crisis is found. This dynamic relationship between stock market and foreign exchange market is consistent with stock-oriented exchange rate models.     

Are the East Asian markets integrated? Evidence from the ICAPM

We test a conditional international asset pricing model with both world market and domestic risk included as independent pricing factors for five East Asian markets, the US and World markets. We model second moments and risk exposures using a bi-diagonal multivariate GARCH(1,1) process. We document that this novel GARCH specification provides a significantly better fit of the return process than a standard diagonal specification. Although exposure to world market risk carries a significant premium across all markets, we find little support for the hypothesis that exposure to residual country risk is rewarded. However, residual country returns are significantly related to exchange rate changes. Hence, we find surprisingly little evidence of market segmentation in East Asia over the period 1985–1998.
