Corporate Diversification and Risk: Portfolio Effects and Resource Redeployability

By analogy with portfolio diversification by stock market investors, managers and researchers have often expected that firms that spread operations across product or geographic markets reduce risk. However, numerous exploratory studies in corporate strategy and in international business have not been able to robustly confirm this expectation. This study develops a formal model to scrutinize implications of corporate diversification for corporate risk. The model incorporates the key distinction of corporate diversification, economies of scope, that qualifies the analogy between corporate and portfolio diversification. The presence of a particular type of economies of scope, resource redeployability, not only inherently increases risk but it can also raise risk over the level in undiversified firms. The model uses determinants of resource redeployability from previous research to derive conditions with which corporate diversification enhances risk. The developed elaborate operationalization of corporate risk should facilitate future research and help corporate managers.

An Optimal Control Approach to Portfolio Diversification on Large Cap Stocks Traded in Tokyo Stock Exchange

In this chapter, Markowitz mean-variance approach is proposed for examining the best portfolio diversification strategy within three subperiods which are during the global financial crisis (GFC), post-global financial crisis, and during the non-crisis period. In our approach, we used 10 securities from five different industries to represent a risk-mitigation parameter. In this way, the naive diversification strategy is used to serve as a comparison for the approach used. During the computation process, the correlation matrices revealed that the portfolio risk is not well diversified during non-crisis periods, meanwhile, the variance-covariance matrices indicated that volatility can be minimized during portfolio construction. On this basis, 10 efficient portfolios were constructed and the optimal portfolios were selected in each subperiods based on the risk-averse preference. Performance-wise that optimal portfolio dominated the naïve strategy throughout the three subperiods tested. All the optimal portfolios selected are yielding more returns compared to the naïve portfolio.

Institutional investor management of Australian healthcare property assets as a pandemic-proof asset class

PurposeAs the prolonged effect of the COVID-19 pandemic has materially impacted investment returns significantly, it is more crucial than ever for institutional investors to redefine their property portfolios using assets with better investment management potential and meaningful diversification benefits. The “alternative asset revolution” is gaining traction in the property investment space internationally among institutional investors due to the shifting investment attitudes towards the alternative property sectors. Australia's $205bn healthcare property sector is at the forefront of this revolution due to its societal significance, as well as its attractive investment qualities. This paper investigates the institutional investor management of the Australian healthcare property sector via both the direct and listed channels and empirically analyses its investment attributes.Design/methodology/approachUsing the unique Morgan Stanley Capital International/Property Council of Australia quarterly data set for Australian direct healthcare property over 2006–2020, the risk-adjusted performance and portfolio diversification potential direct healthcare property and listed healthcare were assessed. A constrained mean-variance portfolio optimisation framework was used to develop a six-asset portfolio scenario to analyse the portfolio added-value benefits of both direct healthcare property and listed healthcare in a mixed-asset investment strategy. A similar set of analysis was performed using the post-global financial crisis (GFC) quarterly time series of 2009–2020 to investigate the healthcare asset class' performance dynamics in the post-GFC investment timeframe.FindingsThe results indicate that direct healthcare property and listed healthcare offer two key advantages for institutional investors in managing their property portfolios: (1) a stable yet superior risk-adjusted performance and (2) significant portfolio diversification potential in managing their property portfolios. Importantly, both direct healthcare property and listed healthcare provided valuable contributions in strengthening an investment portfolio's performance. The post-GFC sub-period analysis revealed a consistent conclusion regarding the healthcare asset class's performance attributes.Originality/valueThis is the first research that provides an independent empirical examination of the strategic importance of Australian healthcare property as a maturing alternative property sector that can serve both investment and environmental, social and governance goals of investors. This research presents a positive investment prognosis for the Australian healthcare property sector to achieve its institutionalised status as a mainstream asset class of the future.

The impact of Islamic portfolio on risk and return

The purpose of this study is to investigate the comparative impact of conventional and Islamic bonds over returns. It provides useful insights to investors to diversify investment by lowering the risk to the optimum level. This study examines the impact of the conventional and Islamic portfolios on returns through simple OLS regression, suggesting that Sukuk returns are positive and significant. Simultaneously, conventional bonds show a negative trend, but in the long run, the returns are significant. It indicates that the market is volatile due to macroeconomic factors that can reduce risks through portfolio diversification. Thus, this research suggests that investment can be secured by taking a rational portfolio decision that confirms robustness. Therefore, it is a good opportunity for the investors to get high margins over the investment tenure.

Volatility Spillover Dynamics between Large-, Mid-, and Small-Cap Stocks in the Time-Frequency Domain: Implications for Portfolio Management

The connectedness dynamics between large-, mid-, and small-cap stocks is investigated using the forecasted error variance decomposition (FEVD) spillover framework of Diebold and Yilmaz in the time-frequency domain. Total volatility spillover (i.e., connectedness) is elevated between large-, mid-, and small-cap stocks during the study period. This high level of spillover exists in the short run only, and declines gradually in the medium to long run, thus providing opportunities for portfolio diversification (hedging) in multi-cap investing during the medium-to-long run (short run) only. Like total connectedness, a similar pattern of bilateral connectedness is observed between either of the two indices, thus providing a similar opportunity in the short and long runs. The mid-cap index emerges as the major contributor to total volatility in the system, followed by the small- and large-cap indices, during the analyzed period. The volatility spillover is time-varying in both the time and frequency domains.

Uncharted waters: Investors get access to foreign exchange-traded funds

In 2022, Russian investors will get access to the wide possibilities of the global financial market. The Bank of Russia opens the market for foreign exchange-traded funds (ETFs) — one of the main savings instruments for households. The economy of ETFs differs from other investment funds, whose shares do not have secondary market. The opening of the ETFs market is intended to solve a number of issues for retail investors: moving away from the preference to individual foreign shares towards portfolio diversification, cost reduction, ensuring sustainable profitability, abandoning the aggressive securities trading, and supporting market competition. Soon, ETFs will be one of the driving forces in financial markets. However, their rapid growth is fraught with little-studied effects.
