Firm Level Evidence On International Stock Market Comovement

We explore the link between international stock market comovement and the degree to which firms operate globally. Using stock returns and balance sheet data for companies in 20 countries, we estimate a factor model that decomposes stock returns into global, country-specific and industry-specific shocks. We find a large and highly significant link: on average, a firm raising its international sales by 10 percent raises the exposure of its stock return to global shocks by 2 percent and reduces its exposure to country-specific shocks by 1.5 percent. This link has grown stronger since the mid-1980s.

Using newly-constructed data covering the last decade, we document that, in most of forty markets, when added to the main index, firms’ returns experience an increase in comovement with the rest of the index, reflected in higher beta and greater explanatory power of the market return. Stock turnover and analyst coverage also typically increase upon inclusion. Using various tests, we find the demand-based view of comovement (the category/habitat theories of Barberis, Shleifer and Wurgler, 2005) to provide a good explanation for many of our findings. Some results, though, suggest that information-related factors are also important in explaining the increased comovement.

The degree of comovement across national stock markets has increased dramatically since the mid-1990s. This has overturned a stylized fact in the international portfolio diversification literature that diversifying across countries is more effective for risk reduction than diversifying across industries. We investigate if this rise in comovement is a permanent phenomenon driven by greater economic and financial integration, or a temporary effect associated with the recent stock market bubble. At the global level, our results point to the bubble. At a regional level, we find evidence of a significant rise in market integration within Europe, possibly a reflection of institutional changes such as the EMU.

Handbook of Frontier Markets: Evidence from Asia and International Comparative Studies provides novel insights from academic perspectives about the behavior of investors and prices in several frontier markets. It explores finance issues usually reserved for developed and emerging markets in order to gauge whether these issues are relevant and how they manifest themselves in frontier markets. Frontier markets have now become a popular investment class among institutional investors internationally, with major financial services providers establishing index-benchmarks for this market-category. The anticipation for frontier markets is optimistic uncertainty, and many people believe that, given their growth rates, these markets will be economic success stories. Irrespective of their degrees of success, The Handbook of Frontier Markets can help ensure that the increasing international investment diverted to them will aid in their greater integration within the global financial system. Presents topics in the contexts of frontier markets and uses tests based on established methodologies from finance research Features contributing authors who are established university academics Emphasizes financial institutions and applications of financial risk models Explores finance issues usually reserved for developed and emerging markets in order to gauge whether these issues are relevant and how they manifest themselves in frontier markets

For a sample of 83 financial institutions during 2003–2011, this paper attempts to answer three questions: first, what is the evolution of banks’ stock price exposure to country-level and global risk factors as approximated by equity indices; second, which bank-specific characteristics explain these risk exposures; third, are there clusters of banks with equity price linkages beyond market risk factors. The paper finds a rise in sensitivities to both country and global risk factors in 2011, although on average to levels still below those of the subprime crisis. The average sensitivity to European risk, specifically, has been steadily rising since 2008. Banks that are reliant on wholesale funding, have weaker capital levels and low valuations, and higher exposures to crisis countries are found to be the most vulnerable to shocks. The analysis of bank-to-bank linkages suggests that any “globalization” of the euro area crisis is likely to be channelled through U.K. and U.S. banks, with little evidence of direct spillover effects to other regions.

This timely volume addresses three important recent trends in the internationalization of United States equity markets: extensive market integration through foreign investment and links among stock prices around the world; increasing securitization as countries such as Japan come to rely more than ever before on markets in equities and bonds at the expense of banks; and the opening of national financial systems of newly industrializing countries to international financial flows and institutions, as governments remove capital controls and other barriers. Eight essays examine such issues as the current extent of international market integration, gains to U.S. investors through international diversification, home-country bias in investing, the role of time and location around the world in stock trading, and the behavior of country funds. Other, long-standing questions about equity markets are also addressed, including market efficiency and the accuracy of models of expected returns, with a particular focus on variances, covariances, and the price of risk according to the Capital Asset Pricing Model.

This paper describes the importance of luck, timing, and political institutions in beating inflation. The paper highlights that countries experiencing high inflation typically make several disinflation attempts, some of which succeed only temporarily. If a country trying to stabilize prices and wages is unlucky enough to be exposed to severe external shocks—for example, a decline in demand for its exports—during its disinflation, the likelihood of failure is increased. A shock such as an increase in U.S. interest rates makes failure more likely for a country with an open capital account.
