Socially responsible investing and stock performance: New empirical evidence for the US and European stock markets

This paper empirically examines the theoretically ambivalent relationship between socially responsible investing (SRI) and stock performance. It contributes to the existing literature by considering both the US and the entire European stock markets and by using consistent world-wide corporate sustainability performance data. Our portfolio analysis from 1998 to 2009 is based on the common four-factor model according to Carhart (1997), which comprises market return, size, value, and momentum factors. We show for the US and the European stock markets that SRI is associated with large-sized firms. The insignificant abnormal stock returns for SRI in both regions are the main result of our paper. Therefore, our study supports the view that SRI stocks are correctly priced by market participants, although we cannot rule out that a corresponding mispricing has existed before the beginning of our observation period in 1998.     

Selecting a portfolio with skewness: Recent evidence from US,European, and Latin American equity markets

Polynomial goal programming, in which investor preferences for skewness can be incorporated, is utilized to determine the optimal portfolio from Latin American, US and European capital markets. The empirical findings suggest that the incorporation of skewness into an investor’s portfolio decision causes a major change in the resultant optimal portfolio. The empirical evidence indicates that investors do trade expected return of the portfolio for skewness.     

New ESG rating drivers in the cross-section of European stock returns

We assess the performance of two quantitative signals based on ESG scores across a large, multi-national cross-section of European stock returns. We test whether the cost of equity capital is more influenced by the upward momentum (measured over time) of the ESG scores of the firms issuing stocks or by their stability (identified as the volatility of the scores over time), measured around a changing mean level. We find that short-term ESG momentum over 1 month has a significant impact on the cross-section of stock returns, lowering the anticipated cost of capital and leading to positive average abnormal returns. This suggests that short-term ESG momentum may represent a novel, priced systematic risk factor. Furthermore, we find strong evidence that an ESG volatility spread strategy which buys low ESG score volatility stocks and sells high volatility ones, generates a substantial alpha and affects the ex-ante cost of capital. Both quantitative ESG signals result in portfolio sorting and long-short strategies that enhance the overall sustainability profile of the issuing firms without compromising the raw average of their ESG scores.     

Risk and return implications from investing in emerging European stock markets

The dynamic linkages and the effects of time-varying volatilities are investigated for major emerging Central European (CE) and developed stock markets. Risk and return implications for portfolio diversification to these markets are assessed, causal lead–lag relationships are identified and asymmetric volatility effects are evaluated. The presence of one cointegration vector indicates market comovements towards a stationary long-run equilibrium path. Central European markets tend to display stronger linkages with their mature counterparts rather than their neighbors. An asymmetric EGARCH model indicates varying but persistent volatility effects for the CE markets. International portfolio diversification can be less effective across cointegrated markets because risk cannot be reduced substantially and return can exhibit a volatile reaction to domestic and international shocks. The possibility of arbitrage short-run profits, however is not ruled out.     

Selecting macroeconomic variables as explanatory factors of emerging stock market returns

Emerging stock markets have been identified as being at least partially segmented from global capital markets. As a consequence, it has been argued that local factors rather than global factors are the primary source of equity return variation in these markets. This paper seeks to address the question of whether local macroeconomic variables have explanatory power over stock returns in emerging markets. Moderate evidence is found to support this contention. Furthermore, using a principal components approach, two types of commonality in returns are examined. Evidence is found that supports commonality in the factors that drive return variation across emerging markets. A test is also conducted for identical sensitivity to a common set of extracted factors. While little evidence of common sensitivities is found when emerging markets are considered collectively, considerable commonality is found at the regional level. These results have implications for international investors as they suggest that the benefits from diversification are enhanced when the allocation of funds is spread across, rather than within, regions.     

The Timeliness of Income Recognition by European Companies: An Analysis of Institutional and Market Complexity

This study examines international differences in the asymmetric timeliness of accounting earnings by modelling international exposure to different jurisdictions as a firm-specific effect, using an index of regulatory complexity that relates to conditions in each of the capital markets in which the firm's equity is listed. The companies investigated are those with shares cross-listed on European stock exchanges, some of which are also listed in New York. Variation across jurisdictions and markets with respect to earnings timeliness and conservatism can be explained in part as an interaction of market effects and regulatory effects, with some evidence of opposition between the two, and the sensitivity of earnings to stock price changes shows a common, converging trend towards greater accounting conservatism in Europe.     

An investigation of the stability of returns in Western European equity markets

This paper investigates the temporal stability of various dimensions of the returns of 16 European stock markets that are relevant to an analysis of international portfolio diversification. The basic data consist of daily stock market price indices for these markets. This group of indices comprehends a wide range of stock markets differentiated by size, age and technological sophistication, but in each case located in Western Europe. Two main tests were conducted: (a) ANOVA to identify inter-temporal variability and inter-market variability over 24 three-month sub-periods from January 1989 to December 1994, and (b) cluster analysis to identify groups of markets that exhibit similar behaviour patterns. The findings suggest that, while the potential gains from an internationally diversified portfolio restricted to the equities of Western European markets appear to be substantial, the lack of inter-temporal stability in the composition of the optimal portfolio from one period to another makes these gains difficult to achieve in practice.     

European integration and corporate financing

This paper explores the importance of supply of capital for corporate financing. To identify this relation, we examine the impact of two exogenous events, entry to the EU and the adoption of Euro, which caused shifts in equity and credit markets during European integration. Following membership to EU, which eased access to equity capital, firms increase equity financing. Firms increase debt financing after the adoption of Euro, which improved access to international debt capital. We control for globalization, ongoing developments in equity and credit channels, firm characteristics, and the moderating effects of the country of origin.     

Determinants of heterogeneity in European credit ratings

In this study, we empirically analyze the determinants of heterogeneity in rating assessments across different segments of the European loan market. We conduct a benchmarking analysis using rating information on European corporate obligors from nine major Austrian banks that have a large share of foreign lending, particularly in the Central and Eastern European region. We provide evidence that, generally, overall heterogeneity among rating outcomes for foreign markets is higher than for domestic markets. Furthermore, we show that heterogeneity increases in transition economies and those markets where Austrian bank involvement is relatively low. Our evidence supports the hypothesis that heterogeneity in the assessment of credit risk is determined not only by the objective quality of information, which is deemed to be lower in transition economies, but also by the subjective access to information about obligors measured by the level of domestic bank involvement in the respective foreign market. Furthermore, we quantify potential effects on regulatory capital requirements.     

Assessing Bond Market Developments Pot-Euro

As a result of global trends in the financial industry, European financial markets are in the midst of a major transformation, and Economic and Monetary Union (EMU) is acting as a primary catalyst for such change. Over time financial integration will provide European markets with sufficient liquidity and scale to turn them into effective rivals of the U.S. markets.
This paper provides a framework for assessing the likely consequences of EMU for the evolution of European bond markets. First, it discusses broad fundamental shifts in international capital flows and how EMU is expected to affect them. Second, it analyzes in some detail the two most important portfolio shifts expected to accompany Monetary Union: potential changes in currency reserves held by central banks and diversification of international investors' portfolios. Third, it considers the possibility that the asset management industry and households' increased appetite for risk will lead to a major shift on the demand side. On the supply side, it explores the likely effect of Monetary Union on government bond yield spreads and expected changes in the key pricing factors.
The paper concludes with an overview of the considerable growth prospects for the European corporate bond market. In the Euromarket, which has traditionally been the preserve of borrowers of high credit standing, there have already been signs of increased interest in corporate issues, particularly lower-rated ones. The search for higher yields by investors, greater expertise in analyzing credit risks by institutional investors, and reduced issuance in European government bond markets will combine to spur growth in the European corporate bond market. As a consequence, the traditional bank-oriented relations will clearly weaken, and more companies will find opportunities to raise capital and obtain financing at lower cost.     

The world price of liquidity risk

This paper empirically tests the liquidity-adjusted capital asset pricing model of Acharya and Pedersen (2005) on a global level. Consistent with the model, I find evidence that liquidity risks are priced independently of market risk in international financial markets. That is, a security’s required rate of return depends on the covariance of its own liquidity with aggregate local market liquidity, as well as the covariance of its own liquidity with local and global market returns. I also show that the US market is an important driving force of global liquidity risk. Furthermore, I find that the pricing of liquidity risk varies across countries according to geographic, economic, and political environments. The findings show that the systematic dimension of liquidity provides implications for international portfolio diversification.     

American depositary receipts: An analysis of international stock price movements

With significant increases in private capital flows across the globe, there has been a rise in the US listing of foreign stocks as American depositary receipts (ADRs). In this study, we employ cointegration techniques and estimate error-correction (EC) models to examine the degree of integration between US and three foreign equity markets. We find that ADRs are cointegrated with ordinary shares trading in the UK, Japan, and Germany, which implies that for long-term investors, they are a substitute for ordinary shares. Our analysis of the dynamic relationships between ADRs and foreign equities suggest that both markets contribute information pertinent to portfolio valuation. However, the foreign markets are found to be the more important source of information.     

Wavelet timescales and conditional relationship between higher-order systematic co-moments and portfolio returns

This paper investigates the association between portfolio returns and higher-order systematic co-moments at different timescales obtained through wavelet multi-scaling, a technique that decomposes a given return series into timescales enabling investigation at different return intervals. In Australian industry portfolios, the relative risk positions indicated by systematic co-moments at some timescales are different from those revealed in daily returns. A strong positive (negative) linear association between beta and portfolio return and co-kurtosis and portfolio return in the up (down) market is observed in daily returns and at different timescales. The beta risk is priced in the up and down markets. Co-kurtosis is not priced when the beta is in the pricing model. Co-skewness appears to be priced at a relatively high timescale and this is observed only after the up and down separation of market returns.     

Risk contagion among international stock markets

We develop a stochastic volatility model with jumps in returns and volatility to analyze the risk spillover from the U.S. market and the regional market to a number of European countries’ equity markets. The key advantage of this approach compared to the earlier approaches is that it enables us to identify jumps and investigate spillover of extreme events across borders. We find that a large part of the jumps in the local markets are due to the U.S. market and the regional market. The U.S. contribution to the variances is in general below the contribution from the regional market. In general, we observe an increasing integration during the last two decades, which, to some extent, can be related to the advancement of the European Union. Furthermore, we show that the identification of the jumps can be used as a useful signal for portfolio reallocation.     

Alternate approach to unify CAPM and APT

We utilize the joint elliptical distribution to model a multi-factor return generating process and derive an equilibrium multi-beta capital asset pricing model (CAPM) in which the market portfolio and a set of nonelliptical factors are sufficient to price all financial assets. Most important, it is shown that the market portfolio, while generally nonelliptical, can proxy all elliptical factors and hence: including elliptical factors in addition to the market portfolio in the pricing equation contribute nothing to asset pricing. While the representative investor prices the exposure of aggregate wealth to various nonelliptical systematic risk factors, individual securities are priced in accordance to their contributions to different aspects of the risk of aggregate wealth. The present model collapses to the Sharpe-Lintner CAPM when either the market investor is neutral to nonelliptical risk factors or when all risk factors follow a joint spherical distribution. When residuals cancel out of the market portfolio, the present model collapses to Conner (1984) pricing model.     

The European Venture Capital and Private Equity country attractiveness indices

We calculate composite indices to compare the attractiveness of 27 European countries for institutional investments into the Venture Capital and Private Equity asset class. To achieve this we use 42 different parameters, and propose an aggregation structure that allows for benchmarking on more granulated levels. The United Kingdom leads our ranking, followed by Ireland, Denmark, Sweden, and Norway. While Germany is slightly above the average European attractiveness level, the scores are rather disappointing for France, Italy, Spain, and Greece. Our analyses reveal that while the UK is similar to the other European countries with respect to many criteria, there are two major differences, which ultimately affect its attractiveness: its investor protection and corporate governance rules, and the size and liquidity of its capital market. The state of the capital market is likewise a proxy for the professionalism of the financial community, for deal flow and exit opportunities. We determine a reasonable correlation between our attractiveness index scores and actual Venture Capital and Private Equity fundraising activities and prove the robustness of our calculations. Our findings across all the European countries suggest that, while investor protection and capital markets are in fact very important determinants for attractiveness, there are numerous other criteria to consider.     

Forecasting European stock volatility: The role of the UK

This study investigates the lead–lag relationships of volatility among European stock markets. Using weakly realized variance measures, we examine volatility spillover dynamics between the UK and other major stock markets in Europe, thereby identifying a long-run leading role for the UK market portfolio. Lagged UK volatility can significantly predict volatilities in non-UK countries, whereas lagged non-UK volatility has a limited association with UK volatility. Moreover, pairwise Granger causality estimations, predictive regression specifications, and out-of-sample validations reveal that volatility shocks in the UK are gradually reflected in market fluctuations across Europe with varying market-specific delays. Our findings support the limited attention explanation for the volatility predictability of the lagged UK equity index.     

Common factors in international securitized real estate markets

This study investigates the presence of common factors in the securitized real estate markets of the Untied States (US), United Kingdom (UK), Hong Kong (HK), and Singapore (SG). Using a combination of factor analysis and canonical correlation analysis on 10-year monthly return data for 142 real estate securities in the four markets, more common risk factors among real estate securities within a country than across countries are detected. In addition, there is at least one common securitized real estate market factor that is moderately correlated with the world real estate market, and to a lesser extent, with the world stock market. However, the degree of linkage across the four securitized real estate markets is much weaker than the strong linkages present across the four economies. It further appears that the extent to which correlations are found in international securitized real estate markets might largely be due to the increasing integrated nature of the world real economy, rather than a result of the globalization of financial markets. The results are preliminary, but indicative, and suggest that more studies exploring how common factors, together with the local market portfolio, could help explain the return-generating process of securitized real estate.     

Volatility‐Spillover Effects in European Bond Markets

Volatility spillover from the US and aggregate European bond markets into individual European bond markets using a GARCH volatility‐spillover model is analysed. Strong statistical evidence of volatility spillover from the US and aggregate European bond markets is found. For EMU countries, the US volatility‐spillover effects are rather weak (in economic terms) whereas the European volatility‐spillover effects are strong. The bond markets of EMU countries have become much more integrated after the introduction of the euro, and in recent years they have become close to being perfectly integrated. The main driver of the integration appears to be convergence in interest rates.     

Efficiency and the programs to develop capital markets : The Brazilian experience

Recent studies suggest that the main avenue to obtain benefits of international portfolio diversification would be direct portfolio investments in the domestic securities of the various countries. There are many barriers to such investments, the most important being the nature of foreign capital markets. Given the potential for attracting foreign portfolio investments and more efficient mobilization of indigenous resources, many less developed countries (LDCs) have embarked upon programs to develop their local capital markets. Among LDCs, the Brazilian effort stands out as the most innovative and systematic. The efforts to develop the Brazilian market have been quite successful with positive effect on the mobilization and allocation of resources. It also exhibits the institutional- and other characteristics associated with developed markets. Further, the Sao Paulo exchange seems to be at least as efficient as most of the European markets. Unfortunately, the apparent shift since 1975 in government policy toward public sector dominance in the domestic savings transfer process may reverse the market development process.
