Do Foreign Investors Promote Stock Price Efficiency in Emerging Markets?

This paper examines the role of foreign investors in promoting stock price efficiency in emerging stock markets relying on the fact that stock prices in these markets are influenced by both local and global factors. We employ a data sample of Vietnamese‐listed firms on the Ho Chi Minh City stock exchange over the period from 2006 to 2015. We utilize the panel data estimation analysis. The results show that foreign investors accelerate the incorporation of available information into local stock prices. The finding reinforces the important role of foreign investors in domestic stock markets of emerging economies.     

Do financial structures affect exchange rate and stock price interaction? Evidence from emerging markets

We investigated the relationship between stock prices and exchange rates in eleven emerging markets over the period of 1988 to 2014 using cointegration methodology and multivariate granger causality tests. We find that in emerging markets, the inner-financial structure, which reflects the proportion of direct financing and indirect financing, plays an important role in the link between exchange rates and stock prices. For ten out of the eleven emerging markets studied, the financial structure had a significant impact, either through the flow channel or stock channel. The effects of financial-economic structure (FIR) were much smaller.     

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.     

Stock price informativeness and analyst coverage

We examine whether more analyst coverage translates into more informative stock prices and apply this to both developed and emerging markets. We measure price informativeness using the association between current stock returns and future earnings. We argue that more informative stock prices contain more information about future earnings. Results indicate that analysts' activities do not contribute to the impounding of future earnings information into current stock prices, in accordance with the view that analysts are outsiders who do not have full access to firm‐level information. We also find that analysts specialize according to industry and that “industry expertise” is limited to developed countries. Overall, our evidence is consistent with the explanation that analysts focus on gathering and mapping industry‐ and market‐level information (macroeconomic information) into stock prices.

Economic determinants of emerging stock market interdependence

There is a wealth of literature on how integrated stock markets are, but very few studies attempts to determine why stock markets are integrated. However, it is arguably even more important to understand the driving forces behind stock market relationships than to know whether they exist. Such an understanding will provide a better grasp of the functioning of the global stock markets and allow investors and policy-makers to ask additional questions such as: Would an increase in bilateral trade between two countries, for example due to a new trade agreement, change the interdependence of their stock markets? If the growth rate of a particular emerging market falls due to the current global economic downturn, will its stock market drag along all the other stock markets or can it be known beforehand which stock markets are more likely to follow? This study empirically estimates cross-section and time-series models to determine the fundamental factors that influence the correlation and evolvement of the correlation between emerging stock markets.     

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.     

The nature and determinants of comovement between developed,emerging and frontier equity markets: Europe versus Asia‐Pacific

International investors are increasingly attracted towards emerging and frontier markets because of their potential to enhance diversification benefits of a global portfolio. This calls for a rigorous analysis of the nature and determinants of stock market comovement between developed, emerging, and frontier markets in Europe and Asia‐Pacific regions. The findings suggest that unlike their Asia‐Pacific counterparts, European developed, emerging, and frontier stock markets display a higher degree of comovement. Although Asia‐Pacific frontier markets provide good diversification opportunities, investors must be cautioned against their weak financial system. The volatility of returns, gross domestic product growth rate, and the 2008 global financial crisis (GFC) are the key determinants of stock market comovement in Europe. The mechanisms by which comovement in the Asia‐Pacific region is strengthened differ across markets. Comparative analysis of comovement and its determinants across different classes of equity markets and geographies is expected to provide valuable perspectives to global investors, portfolio managers, and policymakers.     

The role of stock markets on environmental degradation: A comparative study of developed and emerging market economies across the globe

It is well established in the literature that stock markets increase both economic activities and energy consumption across countries. Therefore, it is commonly believed that stock markets are expected to have a significant effect on CO₂ emissions. However, it is not known whether these stock markets can contribute to more or less CO₂ emissions. Hence, the goal of this study is to examine the impact of stock market indicators on CO₂ emissions across a global panel of both developed and emerging market economies. The results establish that stock market indicators have a significant negative and positive impact on carbon emissions in developed and emerging market economies, respectively. Furthermore, the findings illustrate the presence of the Environmental Kuznets Curve (EKC) hypothesis, implying that stronger stock markets lead to a further decline in carbon emissions. Given these findings, the study argues that the role of stock markets in the abatement of CO₂ emissions significantly varies across both developed and emerging market economies. Significant implications have to do with the fact that developed markets might have initiated effective policies on listed firms to minimize carbon emissions, while emerging markets are yet to achieve this.     

Relationship between portfolio diversification and value at risk: Empirical evidence

This research explores the risk associated with the stocks prices in the seventeen selected companies that are listed in Indian BSE (100) National as well as portfolios of investment that are constructed from these seventeen companies employed. Additionally, for considering the possibility of international diversification, construction of portfolios of investment form stock price indexes in various emerging markets and developed countries of the world is considered. Correlations for domestically as well as internationally diversified portfolios are computed to unveil the relationship between stock prices of various firms as well as domestic and internationally diversified portfolios of investments. Further, to understand the effect of diversification on the risk associated with each of the portfolios of investments employed, value at risk analysis (VaR) is undertaken for studying the benefits associated with domestic as well as international diversification (if any).The study results show that domestic diversification lowers the expected losses associated with each of the domestic portfolios of investment employed where the international diversification substantially mitigates the portfolio risks. Results from VaR analysis reveal that diversification lowers the portfolio risks and additional reduction in portfolio risks is realized by international diversification.     

Do global factors impact BRICS stock markets? A quantile regression approach

This paper examines the dependence structure between the emerging stock markets of the BRICS countries and influential global factors. Using the quantile regression approach, our results for the period from September 1997 to September 2013 show that the BRICS stock markets exhibit dependence with the global stock and commodity markets (S&P index, oil, and gold) as well as changes in the U.S. stock market uncertainty (CBOE Volatility Index). This dependence structure is often asymmetric and affected by the onset of the recent global financial crisis. By contrast, the U.S. economic policy uncertainty has no impact on the BRICS stock markets.     

Stock index futures markets: stochastic volatility models and smiles

This study examined whether the inclusion of an appropriate stochastic volatility that captures key distributional and volatility facets of stock index futures is sufficient to explain implied volatility smiles for options on these markets. I considered two variants of stochastic volatility models related to Heston (1993). These models are differentiated by alternative normal or nonnormal processes driving log‐price increments. For four stock index futures markets examined, models including a negatively correlated stochastic volatility process with nonnormal price innovations performed best within the total sample period and for subperiods. Using these optimal stochastic volatility models, I determined the prices of European options. When comparing simulated and actual options prices for these markets, I found substantial differences. This suggests that the inclusion of a stochastic volatility process consistent with the objective process alone is insufficient to explain the existence of smiles. © 2001 John Wiley & Sons, Inc.

Exchange rate regimes, globalisation, and the cost of capital in emerging markets

This paper presents a multifactor asset pricing model for currency, bond, and stock returns for ten emerging markets to investigate the effect of the exchange rate regime on the cost of capital and the integration of emerging financial markets. Our results suggest that a fixed exchange rate regime system can help reduce the cost of capital in emerging markets by reducing the currency risk premia demanded by foreign investors.     

Oil and stock markets before and after financial crises: A local Gaussian correlation approach

The effect of financial shocks on the cross‐market linkages between oil prices (spot and futures) and stock markets is examined for four major crises. We employ the local Gaussian correlation approach and find that the two markets were regionalized for most of the 1990s and the early 2000s. Flights from stocks to oil occur in all crisis episodes, except the recent global financial crisis. The view that stock and oil markets behave like “a market of one” after the financialization of commodities is further supported by the presence of contagion between US stock markets and all the benchmark oil markets.

Experience-based corporate corruption and stock market volatility: Evidence from emerging markets

This paper reassesses how “experience-based” corporate corruption affects stock market volatility in 14 emerging markets. We match the World Bank enterprise-level data on bribes with a unique cross-country macroeconomics dataset obtained from the World Bank development indicators. It is found that wider coverage of “realized” corporate corruption in the emerging markets investigated reduces the stock market volatility, attributed to decrease in uncertainty about government policy with regard to the business environment, as implied by the general equilibrium model of Pastor and Veronesi (2012). Overall, our results suggest that stock price volatility decreases as the uncertainty about government policy becomes more predictable, which is consistent with the testable hypotheses of Pastor and Veronesi (2012).     

The valuation of inflation‐indexed and FX convertible bonds

This paper derives a valuation model of inflation‐indexed convertible bonds that incorporates the firm's stock price, inflation indexing and the firm's credit risk. The pricing of inflation‐indexed convertible bonds traded on the Tel‐Aviv Stock Exchange (TASE) was empirically tested by using a comprehensive database. The study is the first to empirically test the pricing of convertibles in emerging markets. It was found that the theoretical values for the bonds are, on average, 1.94% higher than the observed market prices. Unlike previous studies, it was found that the underpricing increases with the moneyness of the convertible. It was found that as the maturity lengthens, the underpricing increases. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:634–655, 2008     

It Is Time to Reexamine the Role of Stock Markets in Developing Economies

Although the many perceived benefits of a stock market may have led to their rapid formation and development aspirations across economies, emerging findings that stock markets may not be as useful as previously thought, even a detraction in the case of some developing economies, raises the question of how practical stock markets may be in different situations. In light of the foregoing and using Fiji as an example, this study argues that it is indeed time to reexamine the role of stock markets in developing economies with a view to restructuring the financial system for improved efficiency and effectiveness.     

Early warning indicators of asset price boom/bust cycles in emerging markets

We apply recently developed early warning indicator systems to a cross-section of emerging markets. We find that, with little or no modification, models designed to predict asset price booms/busts in advanced countries may be useful for emerging markets. The concept of monitoring a set of asset prices, real activity and financial indicators is generally found to be efficacious. We also find that, in addition to this set of variables, early warning indicator systems for emerging countries may be augmented with capital flow indicators.     

Does financial development reduce income inequality and poverty? Evidence from emerging countries

The objective of this paper is to examine whether bank and stock market development contributes to reducing income inequality and poverty in emerging countries. Using dynamic panel data methods with an updated dataset for the period 1987–2011, we assess the finance–inequality–poverty nexus by taking the separate and simultaneous impacts of banks and stock markets into account. Mixed explanatory findings on panel studies suggest that although financial development promotes economic growth, this does not necessarily benefit those on low-incomes in emerging countries. For the finance–poverty link, we find that neither banks nor stock markets play a significant role in poverty reduction.     

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.
