Abstract
Purpose
The main purpose of this paper is to investigate whether Chinese investors can benefit from international diversification and where these benefits are to be found.
Design/methodology/approach
This paper applies an expanding optimization procedure, which is different from the econometric methods or Monte Carlo simulations adopted in many empirical investigations in the literature. The authors' analysis is based on various realized portfolios that are set up at different dates in the sample period.
Findings
Based on a stream of realized portfolios, the authors show that Chinese investors can gain substantially in terms of risk reduction as they venture into foreign markets, regardless of the region into which they choose to diversify and whether in‐sample or out‐of‐sample performance is evaluated. However, the optimal strategies under consideration cannot achieve higher out‐of‐sample expected returns and risk‐adjusted returns than does the domestic investment.
Originality/value
In contrast with those in the literature, the authors' analysis is based on the out‐of‐sample performance of a series of realized optimal portfolios. Their method can address time‐varying correlations that are ignored in most previous research. In addition, this method not only allows them to analyze sizes of diversification benefits but also enables them to examine the major characteristics of international portfolios to gauge the effectiveness of different diversification strategies.

Abstract
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.

Abstract
Purpose
The purpose of this paper is to assess the benefits to investors of international diversification among only Islamic funds. Compared to conventional investors who are not restricted in their choice of funds, Islamic investors are restricted to investing in shari’a-compliant funds, thus giving up some diversification benefits. The possibility of international diversification among only Islamic funds may thus help Islamic investors to invest in accordance to their religious beliefs and still benefit from diversification.
Design/methodology/approach
The paper assesses the benefits of diversification by analyzing the extent of co-integration among four regional Islamic funds and by estimating the short-term and long-term structural dynamics of and among these funds. The paper uses an Autoregressive-Distributed Lag (ARDL) approach to testing the long-run relationships among these funds and use variance decomposition and impulse response functions to examine the structural dynamics of the relationship between these funds. These methods can also be used for predictive purposes and represent, in authors opinion, a useful approach that complements the traditional methodology of static covariance matrix to find the efficient frontier at a given moment in time.
Findings
The results indicate that international diversification can help reduce risk if Asia Pacific Islamic funds and MENA region Islamic funds are invested contemporaneously and/or Asia Pacific Islamic funds and North America Islamic funds, and/or Europe funds and MENA funds. The paper also finds that investors would benefit from investing in North American funds and MENA funds both in the long run and in the short run. Conversely, the paper finds that Europe funds and North American funds are co-integrated in the long-run precluding the opportunity for substantial diversification benefits from these particular portfolio mixes.
Research limitations/implications
The long-run analysis helps passive fund managers and investors in composing their portfolio by providing evidence that some portfolio mixes of different regional Islamic funds lead to better risk return performance than one regional Islamic fund portfolios. The short-run analysis however helps the active fund managers and investors as it suggests that diversifying in the short run and reviewing their portfolio on a regular basis would be beneficial as well.
Originality/value
This analysis justifies the promotion of Islamic finance as the negative correlation between several Islamic funds across the regions studied suggests better opportunities of investments via international diversification making Islamic funds more desirable.

Abstract
Purpose
The purposes of this paper are twofold. First, it analyses the income structure in cooperative financial institutions and examines how traditional and non-traditional incomes are related. Second, it evaluates whether increasing diversification towards non-traditional incomes facilitates or hampers the benefits of financial cooperative owners.
Design/methodology/approach
Data are collected from over 3,100 US credit unions over the period of 1994–2016. A number of modern econometric techniques are employed throughout the analysis, including the use of panel fixed effect, generalised method of moments (GMM) and two-stage least square (2SLS) methodologies.
Findings
Using US credit unions as the empirical setting, the empirical results reveal that the expansion of traditional income leads to a corresponding increase in income from non-traditional activities. However, an increasing reliance on non-traditional income causes a significant drop in interest margins. The authors also find that the extent to which income diversification affects owner benefit varies across credit union types and period of time. While income diversification negatively affects owners' benefits in single common bond credit unions, it has no significant influence on multiple common bond and community credit union owners' benefits. Third, diversification can be beneficial during crisis time, but can be detrimental to owner benefit during normal time.
Originality/value
This paper provides some of the first empirical investigations on the diversification strategy of cooperative financial institutions. Therefore, the results offer significant policy implications for policymakers and market participants on whether financial cooperatives should diversify or specialise.

Abstract
Purpose
The purpose of this paper is to examine the extent to which the Indonesian Shariah compliant investors can benefit from the portfolio diversification with the Islamic indices of its trading partners and selected commodities such as gold, crude oil, and cocoa.
Design/methodology/approach
The authors use daily time series data covering both Islamic and commodity indices starting from June 4, 2007 until December 30, 2016 by the application of multivariate-generalized autoregressive conditional heteroscedastic and continuous wavelet analysis.
Findings
The findings tend to indicate that investors with exposure in Shariah compliant indices of Indonesia and wanting to gain more diversification benefits should invest either in the USA or India Islamic equity. Instead, the greater benefits will be obtained by Shariah compliant investors if they invest in the USA Islamic indices during long-term investment horizons. If investors want to invest in medium investment horizons, investing in India Islamic equity is a viable option. The findings further suggest that gold has a role of diversification benefits as a “safe haven” instrument for investors. It is advisable for the investors that have exposure in commodities (gold, crude oil, and cocoa) and want to invest in Indonesian Islamic equity, they should hold the portfolio for not more than 16 days to gain diversification benefits.
Originality/value
The results of this study are expected to have crucial implications for the Indonesia Shariah compliant investors and portfolio managers because it will help them to understand portfolio diversification benefits with different stock holding periods or investment horizons.

Abstract
Purpose
The strategic partnership between China and ASEAN has resulted in significant financial reforms at the country and regional level. The scale and pace of these changes call for systematic assessments of their bearing on the development and integration of financial markets in this region. The purpose of this paper is to investigate the level of financial integration of the equity markets in China and ASEAN4 countries (Indonesia, Malaysia, Philippines, and Thailand) for the period 2004-2014.
Design/methodology/approach
The authors use the β and σ convergence, dynamic conditional correlation, and wavelet correlation to assess the degree, trend, and change across different time scales of the integration of China-ASEAN4 equity markets. Using two measures of change in return per unit risk and variance, we assess the difference in diversification benefits between an equity portfolio China-ASEAN4 and China-EU.
Findings
The authors find that financial integration across China-ASEAN4 equity markets fluctuated between a moderate level before and after the recent crisis and a higher level during the crisis. The results indicate that investors achieve higher diversification benefits from a cross-industry than a cross-country investment strategy within this region.
Research limitations/implications
Future research should investigate whether local factors and existing cultural and political differences explain the weak to moderate level of integration of China and emerging ASEAN equity markets.
Practical implications
A good understanding of the degree and evolution of the regional financial integration may be used by investors to allocate capital efficiently when adding ASEAN4 equities to a portfolio of Chinese equities.
Social implications
Systematic assessments of the regional financial integration contribute to the effort to mitigate the ensuing cross-border financial contagion during crises.
Originality/value
The authors argue that that the increase in correlations of CHINA-ASEAN4 equity markets during the recent crisis does not reflect a permanent shift in the dynamic of the dominant markets in the region. While investors achieve higher diversification benefits from a cross-industry than a cross-country investment strategy within this region, the diversification benefits are lower for long-term than short-term investors.

Abstract
Purpose
On the backdrop of growing importance of Shariah compliant equity markets, the purpose of this paper is to study cross-country portfolio diversification benefits for investors with major trading partners of Saudi Arabia, namely, USA, China, Japan, Germany and India, who have already invested or tend to invest in Saudi Arabian stock market.
Design/methodology/approach
The authors have investigated time invariant, dynamic correlations at different investments horizons of the investors among Islamic asset classes by applying relevant econometric techniques like multivariate generalized autoregressive conditional heteroscedastic –DCC and continuous wavelet transforms. For robustness, this study also applied maximal overlap discrete wavelet transform.
Findings
The findings tend to indicate that the Saudi Arabian investors have portfolio diversification benefits with all major trading partners in the short-term investment horizon. Interestingly, Saudi Arabian market has the least portfolio diversification benefits with the Chinese market. However, in the long run, all markets are correlated, yielding minimum portfolio diversification benefits and most importantly Saudi Arabian investors have portfolio diversification benefits with the Indian Islamic equity market in almost all investment horizons. The findings are highly consistent across different econometric technique estimations.
Research limitations/implications
The authors are only considering five major trading partners of Saudi Arabia. Also, the authors are using S&P and FTSE shari’ah index. Moreover, the time period of the study is constrained by the availability of shari’ah indices. Econometric limitations are also well documented in the literature.
Practical implications
The results could be beneficial for the investors, portfolio managers, hedge fund managers and institutional investors and also could be useful for the policy makers in their policy-making decisions.
Originality/value
Only very few studies have looked into the benefits of international portfolio diversification from the perspective of local investors as well as the portfolio diversification benefits with the major trading partners of Saudi Arabia. One of the novelties of the method is to make the stock investors, practitioners and policy makers aware of the portfolio diversification benefits available at different time scales such as 4, 8, 16, 32, 64 and 256 trading days as investment holding periods to unveil the true dynamics of co-movement between those different assets.

Abstract
Purpose
The purpose of this paper is to quantify the extent to which the Malaysia-based equity investors can benefit from diversifying their portfolio into the conventional and Islamic Southeast Asian region and the world’s top ten largest equity indices (China, Japan, Hong Kong, India, the UK, the USA, Canada, France, Germany and Switzerland).
Design/methodology/approach
The multivariate GARCH-dynamic conditional correlation is deployed to estimate the time-varying linkages of the selected conventional and Islamic Asian and international stock index returns with the Malaysian stock index returns, covering approximately eight years daily starting from 29 June 2007 to 30 June 2016.
Findings
In general, in terms of volatility, the results indicate that both Asian and international Islamic stock indices are more or less volatile than its conventional counterparts. From the correlation analysis, we can see that both the conventional and Islamic MSCI indices of Japan provide more diversification benefits compared to Southeast Asian region, China, Hong Kong and India. Meanwhile, in terms of international portfolio diversification, the results tend to suggest that both the conventional and Islamic MSCI indices of the USA provide more diversification benefits compared to the UK, Canada, France, Germany and Switzerland.
Originality/value
The findings of this paper may have several significant implications for the Malaysia-based equity investors and fund managers who seek for the understanding of return correlations between the Malaysian stock index and the world’s largest stock market indices in order to gain higher risk-adjusted returns through portfolio diversification. With regard to policy implications, the findings on market shocks and the extent of the interdependence of the Malaysian market with cross-border markets may provide some useful insights in formulating effective macroeconomic stabilization policies in the efforts of preventing contagion effect from deteriorating the domestic economy.

Abstract
Purpose
The purpose of this paper is to examine whether there exist significant benefits from diversification into frontier markets for an Australian investor in comparison to a US investor.
Design/methodology/approach
The study uses the computationally efficient ADCC GARCH model to estimate time-varying correlations of returns. The authors also compare the results to DCC GARCH correlations in order to test whether the results are model-specific. Optimal portfolios with several restrictions were constructed and the results from Australian and US investors were compared. The study also uses a holding out period that is rebalanced at the end of each quarter using new portfolio weights.
Findings
The study finds that there are significant benefits for the Australian investor from diversifying into frontier markets. However, the benefits to the US investor are much higher than that of an Australian investor. The results from the holding out period also present significantly higher benefits to the US investor compared to the Australian investor.
Originality/value
This study examines the diversification benefits to the Australian investor from frontier markets and compares the benefits of the Australian and the US investors. The results emphasise the potential benefits from including frontier markets in the portfolio. The paper also presents a holding out period analysis.

Abstract
Purpose
This study investigates the diversification benefits of multiple cryptocurrencies and their usefulness as investment assets, individually or combined, in enhancing the performance of a well-diversified portfolio of traditional assets before and during the pandemic COVID-19.
Design/methodology/approach
This paper uses two optimization techniques, namely the mean-variance and the maximum Sharpe ratio. The naïve diversification rules are used for comparison. Besides, the Sharpe and the Sortino ratios are used as performance measures.
Findings
The results show that cryptocurrencies diversification benefits occur more during the COVID-19 pandemic rather than before it, with the maximum Sharpe ratio portfolio presenting its highest performance. Furthermore, the results suggest that, during COVID-19, the diversification benefits are slightly better when using a combination of cryptocurrencies to an already well-diversified portfolio of traditional assets rather than individual ones. This serves to improve the performance of the maximum Sharpe ratio portfolio, and to some extent, the naïve portfolio. Yet, cryptocurrencies, whether added individually or combined to a well-diversified portfolio of traditional assets, don't fit in the minimum variance portfolio. Besides, the efficient frontier during COVID-19 pandemic dominates the one before COVID-19 pandemic, giving the investor a better risk-return trade-off.
Originality/value
To the best of the author's knowledge, this is the first study that examines the diversification benefits of multiple cryptocurrencies both as individual investments and as additional asset classes, before and during COVID-19 pandemic. The paper covers all analyses performed separately in previous studies, which brings new evidence regarding the potential for cryptocurrencies in portfolio diversification under different portfolio strategies.
