This chapter investigates the relative magnitude of the benefits of global diversification from the viewpoint of domestic investors in various countries by forming time-rolling efficient frontiers. To enhance feasibility of asset allocation strategies, the constraints of short-sales and over-weighting investments are taken into account. The empirical results suggest that local investors in less developed countries, particularly in Latin America, East Asia, and Southern Europe, comparatively benefit more from global diversification. Investors in the countries of civic-law origin tend to benefit more from global investment than the ones in the common-law states. Although the global market has become more integrated over the past decades, diversification benefits for domestic investors declined but did not vanish. The results of this chapter are useful for asset management professionals to determine target markets to promote the sales of international funds.

The purpose of this chapter is to analyze the possible portfolio diversification opportunities between Asian Islamic market and other regions’ Islamic markets; namely USA, Europe, and BRIC. This study makes the initial attempt to fill in the gaps of previous studies by focusing on the proxies of global Islamic markets to identify the correlations among those selected markets by employing the recent econometric methodologies such as multivariate generalized autoregressive conditional heteroscedastic–dynamic conditional correlations (MGARCH–DCC), maximum overlap discrete wavelet transform (MODWT), and the continuous wavelet transform (CWT). By utilizing the MGARCH-DCC, this chapter tries to identify the strength of the time-varying correlation among the markets. However, to see the time-scale-dependent nature of these mentioned correlations, the authors utilized CWT. For robustness, the authors have applied MODWT methodology as well. The findings tend to indicate that the Asian investors have better portfolio diversification opportunities with the US markets, followed by the European markets. BRIC markets do not offer any portfolio diversification benefits, which may be explained partly by the fact that the Asian markets cover partially the same countries of BRIC markets, namely India and China. Considering the time horizon dimension, the results narrow down the portfolio diversification opportunities only to the short-term investment horizons. The very short-run investors (up to eight days only) can benefit through portfolio diversification, especially in the US and European markets. The above-mentioned results have policy implications for the Asian Islamic investors (e.g., Portfolio Management and Strategic Investment Management).

Research on diversification has produced insights into possible linkages between organizational scale and scope and firm performance. However, the paucity of research on strategy implementation has hindered our understanding of the broader performance implications of diversification. We extend the resource-based view and diversification research by examining how firms can exploit diversifying investments designed to achieve scale and scope economies. Successful firms more effectively structure their resource portfolio, bundle resources into capabilities, and leverage these capabilities when implementing a diversification strategy. We develop a model linking strategies by which firms expand product and geographic market scope to the actions they take to manage resources. We examine three actions – internal development, acquisitions, and strategic alliances – and discuss the implications of these actions using the resource management framework.

This study suggests two new diversification strategies, i.e., tourism-related and tourism-unrelated diversifications which are specifically applicable to the hotel firms. This study aims to investigate which diversification strategy has better benefits toward firm performance. This study includes a complete set of public listed firms of the hotel industry from four Asian countries, namely, Hong Kong, Singapore, China, and Malaysia, covering from years 2001 to 2012. Revealing the advantage and disadvantage of both diversification strategies, the empirical evidence regarding its influences on hotel firm performance are investigated in this study. This study finds a nonlinear relationship between degree of diversification and firm performance. Confronting with the volatile earnings when crises strike tourism sector, this study further shows how the crises affect the relationship between tourism-related/unrelated diversification strategy and hotel firm performance.

We start by looking at the arguments put forth as to why having operations evenly spread in a large number of countries should make firms more profitable. Kim, Hwang, and Burgers (1993) argue, for example, that global market diversification, which they measure as the dispersion of a firm's business between seven global market areas, provides a series of advantages that should allow globally diversified firms to earn both higher return on assets and lower risk. Because their arguments are complex and multifaceted, I cite them in extenso.First, global market diversification offers possibilities for exploitation of economies of scale and scope above and beyond the potential of product diversification (Grant, Jammine, & Thomas, 1988). Second, the diversity of national markets exposes firms to multiple stimuli which provides [sic] with a broader learning opportunity and the ability to develop more diverse capabilities than are available to purely domestic firms…. Third, different nations have different factor endowments which, in the absence of efficient markets, lead to intercountry differences in factor costs. Global market diversification allows firms to gain cost advantages by configuring their value added chain in such a way that each link is located in the country which has the least cost for that link (Kogut, 1985a). Global market diversification thus provides firms with unique opportunities to increase returns by spreading its [sic] activities [emphasis in original] across multiple global market areas, rather than by choosing higher risk activities.At the same time, global market diversification endows firms with three unique options [emphasis in original] over domestic firms which are reasoned to reduce the level of corporate risk. First, global market diversification provides a firm with multiple national market bases from which it can retaliate against aggressive moves made by competitors (Hamel & Prahalad, 1985; Kim & Mauborgne, 1988). This option reduces the risk for the global firm of having to face aggressive challenges from its competitors. Second, the multiplicity of national markets allows firms to minimize the effect of adverse changes in a country's interest rates, wage rates, and commodity and raw material prices by providing the added option to more readily shift production and sourcing sites to other more favorable national markets (Kogut, 1983, 1985b; Porter, 1986). Finally, global market diversification releases firms from the mercy of supply and demand fluctuations of any one national market, smoothing the peaks and troughs of firms’ revenue streams. In sum, the spreading of activities across global market areas provides the firm with operational flexibilities that will serve to reduce earning and profit fluctuations. Taken together, the above discussions suggest that the unique opportunities and options of global market diversification may simultaneously increase firms’ returns and reduce their risk.” (Kim et al., 1993, pp. 276–277)

The study evaluated the interlinkages and diversification opportunities in the context of emerging bond markets from 2007:1 to 2020:5, using the vector autoregressive (VAR) model and sub‐period analyses to compare BRIC (2007:1–2010:11) and BRICS (2010:12–2020:5) regimes. As indicated by the breaking unit‐root test, dummies for the global financial crisis and COVID‐19 were incorporated in the analyses. VAR results showed that the Indian bond market responds positively to the previous change in the Chinese bond market during the BRIC era while BRICS bond markets are mostly uninfluenced by prior behavior patterns of one another. These suggested that the diversification opportunity has been increased following the admission of South Africa to the league. In addition, variance decomposition and impulse response provide proofs to suggest that BRICS bond markets are more exogenous and independent compared to what is obtained during the BRIC period. Consequently, the authors concluded that the BRICS bloc has provided greater diversification opportunities for emerging markets’ bondholders in the recent past.

U.S. bank holding companies (BHCs) have experienced dynamic changes over a period of 2000–2010. We find that the size distribution of sample banks becomes highly positively skewed with a small number of big banks becoming super-sized, and these big banks tend to take extra risk by holding derivative positions for trading purposes. The ten largest risk-taking banks hold about 70% of total assets of all the sample banks in 2010. We investigate whether the risk-taking activities of the BHCs translate into higher risk-adjusted return performance. In extensive panel regression analyses, we find that the risk-taking strategies of large banks by holding derivative positions for trading purpose do not show the clear evidence of enhancing risk-adjusted performance. We find that negative impacts of extra risk-taking on the risk-adjusted performance become bigger with the size of banks.

The real estate market has evolved significantly over the past 10 years and has experienced rapid growth throughout the world in its various forms. Many emerging countries witnessed the significant growth in their commercial real estate markets that became a stable sector of their economies. These countries, after developing a reliable commercial real estate base within their economies subsequently developed real estate financial markets. The growth of the real estate investment trusts, REITs, markets in many countries within the past decade helped attract global capital that facilitated additional investments in local real estate developments. Significantly, this period of time may have witnessed a higher degree of integration of real estate with the broader financial markets due in large part to the securitization of mortgages. Yet the general real estate market was also impacted in many parts of the world with rising prices and subsequent price collapses. This section focuses on the various areas of the global real estate market and the changes that it has encountered as examined by researchers of real estate. This chapter also examines the recent trends in global real estate markets and explores how these changes have affected the broader investment community.
