What are the risks when investing in thin emerging equity markets: Evidence from the Arab world

This study attempts to identify the risks involved when investing in five emerging Arab capital markets. We first find that a constant beta is not a good proxy for risk in these thinly traded emerging markets. However, firms’ fundamentals and country risk rating factors prove significant in explaining the cross-sections of stock returns. The paper provides three important contributions to the literature on asset pricing in emerging capital markets: (i) we show how country risk ratings can be aggregated into a country risk factor; (ii) we add to a growing literature suggesting that, in markets other than the US, it is possible to find large and growth stocks to be riskier than small and value stocks; (iii) we determine that despite economic, financial and political reforms, issues related to financial transparency and political instability are still powerful obstacles to investments in these nascent emerging markets.     

Political Uncertainty, Financial Crisis and Market Volatility

This paper examines the impact of political uncertainty on financial crises using a panel of 22 emerging markets. By examining political election cycles, we find that eight out of nine of the financial crises happened during the periods of political election and transition. Using a combination of probit and switching regression analysis, we find that there is a significant relationship between political election and financial crisis after controlling for differences in economic and financial conditions. We observe increased market volatility during political election and transition periods. Our results suggest that political uncertainty could be a major contributing factor to financial crisis. Thus, politics does matter in emerging markets. Since the odds of financial crisis tend to be much larger during the political election periods, institutional investors should take that into account when making emerging market investment during those time periods.     

The transmission of market shocks and bilateral linkages: Evidence from emerging economies

The linkage between emerging and developed economies spans beyond the usual trade in goods and services. Underlying trade is the flow of capital for foreign direct investment and for speculation in markets, which renders emerging economies vulnerable to shocks from the developed world. As such, equity return volatility in emerging markets is partly attributable to this dependence. To gauge the importance of bilateral economic and cultural factors in driving economic integration, we adopt a two-step process. First, we use Diebold and Yilmaz's spillover index methodology to extract spillover indices representative of the return volatility spillover effects of the United States, the developed portion of the Euro area, and Japan on financial markets in Asia, the Gulf Cooperation Council countries, Eastern and Central Europe, Africa, and Latin America. Second, we test whether these indices are governed by economic and cultural factors. Our results show that the spillover effects vary across markets and that a strong correlation exists with the volume of trade, security investment, common language, distance, and market capitalization.     

Financial reforms and time-varying microstructures in emerging equity markets

This paper seeks to investigate the impact of financial reforms on time-varying microstructures in emerging equity markets. We develop annual indicators of informational efficiency, market volatility and transaction costs, using daily data for a panel of 28 emerging markets over the 1996–2007 period. We then analyze the impact of insider trading regulations, trading system automation and accounting standardization on microstructures through a set of panel regressions controlling for financial development and simultaneous reforms. Our results suggest that emerging market microstructures are affected by economic and political context, are strongly related to one another and depend on specific institutional reforms.     

Empirical Evidence of the Existence of Investable Premiums in Emerging Market Investable Stocks

This paper shows that portfolios of more investable securities bear a premium when compared to portfolios of less investable stocks, reflecting compensation for local risk factors. The investable premium is overwhelmingly priced across 3,782 companies traded in 29 emerging markets from 1988 to 2006. The investable premium impacts stock returns at least as much as other fundamental premiums such as size, value, momentum, and loads on political, economic, and financial risk factors. The impact of the investable premium on emerging stocks returns has increased in strength, implying that foreign ownership has greater influence on local markets in recent years.     

SECURITIZATION: A FINANCING STRATEGY FOR EMERGING MARKETS FIRMS

With emerging markets now in crisis, companies in developing countries are finding it difficult to obtain financing. Securitization, a transaction structure in which the securities sold to investors are backed by a company's receivables, is one of the few vehicles with at least the potential to provide financing at economic rates in the current environment of uncertainty.
Unlike U.S. securitization issues, emerging markets transactions often use a structure known as "future flows" securitization, in which the securities are backed by receivables that are not expected to be generated until after issuance. This article begins by describing how the process of future flows securitization carves out securities with levels of political risk acceptable to foreign capital market investors. Then it traces the history of emerging markets securitization from its origins in Latin America to its more recent uses during the Asian crisis. Securitization helped bring foreign investors back to Latin America after its debt crisis of the early 1980s. And while the Asian crisis has sharply reduced new issuance for all kinds of emerging market financings, the volume of securitization issues appears to have declined less precipitously than other types of transactions geared to foreign investors. Moreover, investment bankers are now hard at work planning new securitization issues for companies in both Latin America and Asia.
In exploring the longer-term effects of securitization on both domestic issuers and their economies, the author suggests that securitization could play a pivotal role in restoring emerging markets companies' access to global financial markets. Indeed, with a few exceptions such as Malaysia, most emerging markets are now responding to the crisis by taking measures to protect investors, such as requiring greater financial transparency and dispelling legal uncertainties that have discouraged securitization in particular and overseas investment more generally.     

A comprehensive investigation on the predictive power of economic policy uncertainty from non-U.S. countries for U.S. stock market returns

This study uses economic policy uncertainty (EPU) indices for ten developed countries, three diffusion models, and five combination methods to forecast excess returns in the U.S. stock market. It shows empirically that, over the period January 1997 to January 2022, non-U.S. EPU indices have better predictive power for U.S. equity market excess returns than the U.S. EPU index itself. This illustrates how economic information from international markets can affect the U.S. stock market. This finding challenges the extensively recognized view that the U.S. is where important market signals are initially transmitted to other markets, suggesting that this belief is incomplete. Our outcomes are robust to a battery of tests covering model selection, model specification, forecast horizons, and the pandemic period, and their economic values are assessed. The findings are essential for the financial field to confront future fierce situations and crises.     

Islamic investing

Using a large international sample of 35 developed and emerging markets, we analyze whether Islamic indices exhibit a different performance to conventional benchmarks. While there is no compelling evidence of performance differences in robust Sharpe ratio tests and after controlling for market risk, we find a significantly positive four-factor alpha for the aggregate developed markets region. This outperformance stems, however, mainly from the U.S. and is largely attributable to the exclusion of financial stocks in Sharia-screened portfolios. As the extensive downturn of financials is related to the recent financial crisis, we do not argue that this outperformance will continue over time. The style analysis reveals that Islamic indices invest mainly in growth stocks and positive momentum stocks. This, for a passive portfolio intriguing result can, however, be explained by the strong sector allocation towards energy firms and their strong momentum characteristic during the sample period.     

试析国际金融危机与全球经济失衡的关系——兼评伯南克-保尔森“金融危机外因论”

伯南克和保尔森认为,以近年来新兴市场经济体储蓄快速增长为特征的全球经济失衡是当前国际金融危机爆发的一个重要原因。本文认为这个看法包含多个难以成立的论点。近年来新兴市场经济体出现的快速储蓄增长不是一种自发性行为,它们的外汇储备增长也不完全是经常账户顺差的结果,中美贸易平衡关系不具有对称性。从根本上说,新兴市场经济体外汇储备增长及其对美国金融市场的投资是国际资金回流当地的一种表现。美国金融市场上的资金供给主要由当地因素决定。国际金融危机的根本原因在于美国乃至世界金融体系风险控制功能的弱化,以美国持续性大规模经常账户逆差为特征的全球经济失衡在可见的未来很可能继续存在。     

Managing risk in an unstable world

With emerging markets like China and politically unstable countries like Saudi Arabia figuring more than ever into companies' investment calculations, business leaders are turning to political risk analysis to measure the impact of politics on potential markets, minimize risks, and make the most of global opportunities. But political risk is more subjective than its economic counterpart. It is influenced by the passage of laws, the foibles of government leaders, and the rise of popular movements. So corporate leaders must grapple not just with broad, easily observable trends but also with nuances of society and even quirks of personality. And those hard-to-quantify factors must constantly be pieced together into an ongoing narrative within historical and regional contexts. As goods, services, information, ideas, and people cross borders today with unprecedented velocity, corporations debating operational or infrastructural investments abroad increasingly need objective, rigorous assessments. One tool for measuring and presenting stability data, for example, incorporates 20 composite indicators of risk in emerging markets and scores risk variables according to both their structural and their temporal components. The indicators are then organized into four equally weighted subcategories whose ratings are aggregated into a single stability score. Countries are ranked on a scale of zero (a failed state) to100 (a fully institutionalized, stable democracy). Companies can buy political risk analyses from consultants or, as some large energy and financial services organizations have done, develop them in-house. Either way, a complete and accurate picture of any country's risk requires analysts with strong reportorial skills; timely, accurate data on a variety of social and political trends; and a framework for evaluating the impact of individual risks on stability.     

Spillovers among sovereign CDS,stock and commodity markets: A correlation network perspective

In the wake of the globalization of financial markets, studying spillovers among different asset markets, especially spillovers that include sovereign CDS markets, is of vital importance. This paper attempts to build a spillover network to investigate the complex interactions within the system of sovereign CDS, stock and commodity markets by adopting the spillover index based on forecast error variance (FEV) decomposition. The results reveal that emerging countries have larger average spillovers than developed countries with regard to sovereign CDS-to-stock returns spillovers, while the developed countries contribute more average spillovers than the emerging countries in the opposite direction. Moreover, the sovereign CDS market and the commodity market still demonstrate a relatively important role during certain periods although stock markets always occupy the dominant position during every phase. Our findings provide new insights into spillovers among the major global asset markets using a network perspective, which is valuable for regulation of financial markets, asset allocation and portfolio risk management.     

Overreaction and underreaction in the foreign exchange market

Research has documented overreaction and underreaction for stocks and stock market indices, but it has not yet analyzed these phenomena with regard to currency exchange rates. This paper examines exchange rate changes following extreme 1-day fluctuations for currencies in industrialized and emerging markets. In this study, the exchange rate is defined as the number of foreign currency units per US dollar. An overreaction phenomenon for currencies in emerging markets and an underreaction phenomenon for currencies in industrial markets are found. Each extreme 1-day currency fluctuation event is classified according to the type of underlying reason as described in the Wall Street Journal. Events for which no announcements (undefined events) were found are associated with a stronger tendency toward overreaction than those events for which an explanation was given (defined events). This suggests that investors overreact more when the source of the extreme fluctuation is largely unknown. The defined events are classified into two groups: economic events and political events. There is some evidence that political events are associated with a stronger tendency toward overreaction than economic events. These findings can be attributed to uncertainty. Political events (e.g., civil uprising) should be more difficult to assess than economic events (e.g., the release of an inflation report), and undefined events should be associated with the largest degree of uncertainty. Cross-sectional analysis is used to relate post-event exchange rate changes to the magnitude of the initial exchange rate change, leakage, day of the week effects, type of currency (from emerging or industrial market), and the type of announcement (economic, political, or undefined) that appeared in the Wall Street Journal. The cross-sectional analysis confirms that currencies in emerging markets experience stronger degrees of overreaction than those of industrial markets, even after controlling for potentially confounding factors. Moreover, it confirms that undefined events experience stronger degrees of overreaction than defined events, even when controlling for other factors.     

Financial market stability—A test

This paper proposes a definition for financial market stability and an econometric test. It analyzes the impact of systematic and systemic shocks on developed and emerging market stock indices in normal and extreme market conditions. Financial market stability is defined as a constant impact of systematic shocks in normal and extreme market situations. Empirical results show that the impact of systematic shocks is significantly larger in extreme market conditions than in normal conditions for emerging markets. In contrast, the relationship is stable for developed markets. Hence, only developed markets meet an essential condition for financial market stability.     

Do low-carbon investments in emerging economies pay off? Evidence from the Brazilian stock market

Climate change has created both challenges and opportunities for investors worldwide. Investing in carbon-efficient assets, for instance, may reduce investors' climate risks while contributing to global efforts for climate change mitigation. Investors need updated and robust information on the financial performance of low-carbon investments, especially in emerging markets, where climate finance initiatives are still scattered. In this work, we provide a first insight into the financial performance of a portfolio of shares from Brazilian carbon-efficient companies. To that end, we use as reference the Carbon Efficient Index (ICO2) and assess its financial performance from 2010 to 2019 through the lens of several classic and modern portfolio metrics. We find that the index outperformed both the Brazilian market benchmark and the country's broad sustainability index, and provided competitive risk-adjusted returns compared with other sectorial indices. The results thus indicate that investing in carbon-efficient companies in Brazil has so far positively contributed to portfolio performance while offering investors an opportunity to reduce climate risk exposure in stock markets.     

The 2008 financial crisis: Stock market contagion and its determinants

In this paper, we investigate worldwide contagion and its determinants during the 2008 financial crisis. Utilizing an international sample of returns from 2003 to 2009, we consider both uni- and bi-directional contagion. After controlling for crisis-related volatility, we find strong evidence that cross-market linkages increase among many financial markets. In contrast to previous crises, contagion following the 2008 global financial crisis is not confined to emerging markets. The United States and other mature financial markets in the sample transmit and receive contagion. Country markets are less influenced by regions than they are by other country markets. We also construct variables that represent relative changes in economic variables before and during the crisis. We find that both economic fundamentals such as trade structure, interest rates, inflation rates, industrial production, and regional effects, and investors’ risk aversion contribute to international contagion.     

The transmission of emerging market shocks to global equity markets

The paper analyzes whether, and to what extent, emerging market economies (EMEs) have systemic importance for global financial markets, above and beyond their influence during crises episodes. Using a novel database of exogenous economic and political shocks for 14 systematically relevant EMEs, we find that EME shocks not only have a statistically but also economically significant impact on global equity markets. The economic significance of EME shocks is in particular underlined by their remarkably persistent effects over time. Importantly, EMEs are found to influence global equity markets about just as much in “good” times as in “bad” times, though they tend to be stronger during crises or periods of financial turbulence. Finally, we detect a large degree of heterogeneity in the transmission of EME shocks to individual countries' equity markets, stressing the different degrees of financial exposure, which is relatively higher for European equity markets.     

Sources of Fluctuations in Islamic,U.S., EU,and Asia Equity Markets: The Roles of Economic Uncertainty,Interest Rates,and Stock Indexes

This article analyzes the economic and financial sources of fluctuations among the U.S. federal funds rates, the U.S. economic policy uncertainty, and the indices of the U.S., European, Asian, and Islamic stock markets. The impulse response analysis shows that the U.S. economic policy uncertainty shocks have significant and negative effects unanimously on the U.S., European, Asian, and Islamic stock markets. A contractionary monetary policy shock, in terms of a higher federal funds rate, has also a statistically significant and negative effect on all of the stock markets. The variance decomposition results indicate that the Islamic stock index is mainly affected by the U.S. stock index shock, thus negating its dichotomy hypothesis. The U.S. economic uncertainty shock explains an important portion of fluctuations for all four stock indices. The degree of synchronization between the EU stock market and other markets has weakened after the U.S. financial crisis.     

What drives portfolio investments of German banks in emerging capital markets?

After decades of steady liberalization and financial market development, emerging capital markets experienced unparalleled capital inflows in the aftermath of the emerging markets crisis of the 1990s. This paper studies portfolio investment decisions of German banks in emerging capital markets from 2002 to 2007. The use of a dynamic time-series cross-section framework and the micro database External Position Report provided by Deutsche Bundesbank permit insights into the various determinants of portfolio investments in ECMs. For example, there is evidence that German banks take into account the various dimensions of financial market development in their portfolio investment decisions and anticipate the special risks inherent in emerging markets. Proxies for the overall development and efficiency of capital markets have the highest economic significance of all variables. The introduction of depositary receipts programs has a positive impact on stock market investment. Moreover, there is evidence that global risk aversion exerts a significant influence in times of financial turmoil.     

波动溢出网络视角的金融风险传染研究

当前各类经济风险交叉关联,金融系统的风险溢出效应备受关注,为刻画我国金融系统性风险传染的路径特征,本文从波动溢出网络的视角分析金融系统内部的风险传染机制。首先使用广义动态因子模型对收益波动的共同波动率成分和特质性波动率成分进行区分。然后,根据货币市场、资本市场、大宗商品交易市场、外汇市场、房地产市场和黄金市场之间的特质性波动溢出效应,利用基于TVP-VAR模型的方差分解溢出指数分析金融系统波动溢出的动态联动性和风险传递机制。在分析方向性波动溢出效应的基础上,采用方差分解网络方法构建起信息溢出复杂网络,从网络视角分析金融系统内部的风险传染特征。实证研究发现,房地产市场和外汇市场的净溢出效应绝对值相较于其他市场更大,其受其他市场风险冲击的影响强于对外风险溢出效应,而股票市场的单向对外风险溢出效应强度最大。在波动溢出的基础上,进一步考虑股市波动率指数与其他市场波动率指数进行投资组合的资产配置权重,计算了波动率指数投资组合的最优组合权重和对冲策略。研究结论有助于更好地理解我国金融系统的风险传染机制,对监管机构加强宏观审慎监管、投资者规避投资风险具有重要意义。     

A note on cointegration of international stock market indices

Cointegration is frequently used to assess the degree of interdependence of financial markets. We show that if a stock's price follows a stock specific random walk, market indices cannot be cointegrated. Indices are a mere combination of n different random walks which itself is non-stationary by construction. We substantiate the theoretical propositions using a sample of 28 stock indices as well as a simulation study. In the latter we simulate stock prices, construct indices and test whether these indices are cointegrated. We show that while heteroscedasticity misleads cointegration tests, it is not sufficient to explain the high correlation between stock market index returns. A common random walk component and correlated price innovations are necessary to reproduce this feature.
