Abstract

Purpose

This paper aims to investigate empirically whether Islamic securities enhance economic growth in the Southeast Asian region based on the endogenous growth theory using the non-parametric analysis.

Design/methodology/approach

This paper applies panel quantile regression with Markov chain Monte Carlo optimization as an optimal non-parametric approach to investigate the effect of Islamic securities on economic growth starting from 2013Q4 to 2019Q4 in Southeast Asia. Total issued Islamic securities holdings are employed as a measure for Islamic securities, while the gross domestic product is employed as a proxy for economic growth. The sample includes all working Islamic financial foundations in the top progressive Islamic securities markets' countries of Southeast Asia (Malaysia, Indonesia and Brunei Darussalam).

Findings

The findings confirm that the increase of issuing Islamic securities in Islamic capital markets of Southeast Asia is increasing the levels of economic growth, reflecting the weighty role of the Islamic capital market development as an active contributor to economic growth.

Practical implications

This research would fill the literature gap by exploring Islamic securities–economic growth nexus in Southeast Asia using a robust non-parametric approach based on the endogenous growth theory for better estimation results. The findings of this review serve as a roadmap for financial analysts, policymakers and decision makers to stimulate the Islamic securities markets as another source of finance which can promote the economic growth.

Originality/value

This research is the first that investigates empirically the Islamic securities–economic growth nexus in Southeast Asia using a new empirical investigation built on the non-parametric analysis and outlined within the theoretical context of the endogenous growth model to gain robust evidence about this nexus.

Abstract

In 2022, US financial regulators proposed to mandate a single central clearing mechanism for treasury bonds and repo transactions to stabilize financial markets. The systemic risks inherent in repo markets were first highlighted by the global financial crisis and, as a response, global financial authorities such as the Financial Stability Board (FSB) and Bank for International Settlements (BIS) have advocated for the introduction of a central counterparty (CCP). This study examines the structural characteristics of Korean repo markets and proposes the introduction of CCPs as a way to mitigate systemic risk. To this end, the author analyzes the structural differences between US and European repo markets and estimates the potential consequences of introducing CCP clearing in local repo markets. In general, CCPs offer two benefits: they can reduce required capital through netting in multilateral transactions, and they can mitigate the effects of risk transfer by isolating counterparty risk during periods of turbulence. In Korea, the latter effect is expected to play a pivotal role in mitigating potential risks.

Abstract

Purpose

It is important to note that insider trading is currently outlawed under the Securities Act 17 of 2004 (Chapter 24: 25) as amended (Securities Act) in Zimbabwe. This Act enumerates some practices that may give rise to insider trading liability in the Zimbabwean financial markets. Nonetheless, numerous challenges, such as the lack of adequate financial resources, the lack of sufficient persons with the relevant skills and expertise on the part of the enforcement authorities, lack of political will, inadequacy of insider trading provisions, poor cooperation and collaboration between the relevant authorities and the ongoing coronavirus (Covid-19) pandemic have negatively impeded the effective regulation and combating of insider trading in Zimbabwe. To this end, the author explores the stated challenges and recommend measures that could be used by regulatory bodies and other relevant enforcement authorities to enhance the regulation and combating of insider trading in the Zimbabwean financial markets. This study aims to enhance the detection and combating of insider trading in Zimbabwe.

Design/methodology/approach

A qualitative research methodology is used through the analysis of relevant legislation and case law.

Findings

It is hoped that the findings and recommendations made in this study will be considered by the Zimbabwean policymakers.

Research limitations/implications

The study does not use empirical research methodology.

Practical implications

The findings and recommendations made in this study could enhance the combating of insider trading activities in Zimbabwe.

Social implications

The study seeks to curb insider trading in the Zimbabwean financial markets and financial institutions in the wake of the covid-19 pandemic-related regulatory and enforcement challenges.

Originality/value

The study provides original research on the regulation and combating of insider trading activities in Zimbabwe.

Abstract

Purpose

The study aims to examine the appropriateness of the coefficient of elasticity of trading (CET) as a measure of liquidity using Nigerian stock market data. Given that liquidity is multidimensional, the CET is complemented with the popular measure of liquidity, turnover ratio to explore the causal relationship among the CET, turnover ratio and market return to determine their relevance in security valuation. In other words, an attempt is made to examine if either of these two measures of liquidity is a relevant factor in explaining stock market return.

Design/methodology/approach

The Toda-Yamamoto version of Granger causality test is applied to two sets of data on the Nigerian Stock Exchange (NSE). The available monthly time series data are from 2008 to 2019 while the annual data are from 1986 to 2018. The Toda-Yamamoto test is preferred because it is more robust to integration and cointegration of the variables.

Findings

The results of the Toda-Yamamoto version of the Granger causality test on monthly data reveal no causal relationship between CET and market return, turnover and market return and CET with turnover and market return. These results are consistent with those for several frontier countries reported by Rubio et al. (2005), Hartian and Sitorus (2015), Batten and Vo (2019) and Sterenczak et al. (2020). The results support the conclusion that the Nigerian economy is not fully integrated with the global economy. Market inefficiency due to order imbalances given the nature of the trading system can also explain the reported results. However, the results from annual data do not tally with the monthly results. There is causality running from CET to market return. There is also causality running from turnover to market return. Therefore, both CET and turnover are statistically significant causal predictors of market return. The results from annual data are consistent with those reported by Marozva (2019).

Research limitations/implications

The key limitation is availability of high-frequency transaction-level data to researchers to consider many measures of liquidity that have been employed in developed countries. The research implication is that more researchers will be encouraged to conduct more studies on liquidity and how the study results can drive policy recommendations. The standard asymptotic distribution of underlying the Toda-Yamamoto approach has been found to lead to overrejection.

Originality/value

This study is the first to apply Toda-Yamamoto model on data from Nigeria to investigate the causal relationship between stock market return and liquidity proxied by the CET given the nature of the automated trading system (ATS) in use. The CET is also complemented with the turnover ratio to explore the multidimensional nature of liquidity and its causal relationship with market return. The study is also interpreted as a determination of the integration of Nigeria's economy with the global economy with its implication on investment diversification.

Abstract

Purpose

The capital asset pricing model has failed to explain the effect of systematic risk (referred to as beta) on actual stock market returns. Accordingly, this study analyzes daily returns by splitting it into overnight and daytime returns. The study analysis empirically confirms a positive relationship between overnight returns and beta and a negative relation between daytime returns and beta. Furthermore, this paper aims to determine that empirical results are mostly the same with three different beta calculations, namely, daily, overnight and daytime returns. The study concludes that beta on overnight returns has the strongest explanatory power and is statistically significant.

Abstract

Purpose

While every firm is striving to embrace digital transformation (DT) to form new differentiating business capabilities, there are dark sides to such initiatives, and it is essential to acknowledge, identify and address them. The purpose of this paper is to identify and emperically demonstrate the impact of such darksides of DT. While a firm's DT effort may have many dark sides, the authors identify data breaches as the most critical one and focus on proving their impact since it can inflict significant damage to the firm.

Design/methodology/approach

Through the lens of paradox theory, the authors argue that the DT efforts of a firm will lead to increased risk and severity of data breaches. The authors developed a one-of-a-kind longitudinal data set by combining data from multiple sources, including 3604 brands over a 10-year period, and employed a DT performance scorecard to evaluate a firm's DT effort across four key digital selling touchpoints: site, mobile, digital marketing and social media.

Findings

The findings of this study show that a firm's DT efforts pertaining to its mobile and digital marketing platforms significantly increase the likelihood and severity of a data breach event indicating that these two channels are most vulnerable and need heightened attention from firms. Furthermore, the findings suggest that the negative repercussions of some DT initiatives may be minimized as the firm becomes more innovative. The findings can help firms re-strategize their DT efforts by promoting security and also encouraging a balanced communication strategy.

Originality/value

This research is one of the first to identify, recognize and empirically illustrate the downsides of a DT effort that is otherwise thought to provide only benefits.

Abstract

Purpose

The purpose of this paper is to present an overview of the flash crash, and explain why and how it happened.

Design/methodology/approach

The author summarizes several studies suggesting various perspectives on the flash crash and its causes. Furthermore, the author highlights recently proposed and introduced improvements and regulations to reduce the risk of having similar market collapses in the future.

Findings

It is an overview paper that highlights the state of the art on the subject.

Research limitations/implications

Paper does not report any research findings of the author.

Practical implications

High-frequency trading (HFT) along with its pros and cons is the new normal for most of the current electronic trading activity in the markets. It is well recognized by the experts that HFT may have its important shortcomings whenever the rules and regulations are not up to date to match the technological progress offering faster computational and execution capabilities.

Social implications

HFT has created a societal discussion about its benefits and potential deficiencies as the common practice for trading due to potentially unequal access to market data by various categories of participants. Such arguments help the regulators to develop improvements to reduce the market risk and nurture more robust and fair markets for all.

Originality/value

The paper has a tutorial value and summarizes the current state of HFT. The readers of more interest are guided to the most relevant literature for further reading.

The authors investigate how foreign investment in securities market informs about the future firm performance in emerging markets.

Abstract

Purpose

The authors investigate how foreign investment in securities market informs about the future firm performance in emerging markets.

Design/methodology/approach

The authors define the independent variable, abnormal foreign investment (AFI) as the residuals of the foreign ownership equation. The authors regress foreign ownership on its first lag and factors and define the residuals as the AFI. The AFI is the over- or under-investment reflecting foreign conscious (clear-purpose) investment, thus better indicating how foreign investment affects firm performance. The dependent variable is Tobin’s q (Q), which represents the firm performance. Then, the authors regress the Tobin’s q next quarters (Qt + k) on the AFI current quarter (AFIt). The authors use a two-step generalized method of moments (GMM) and check endogeneity with the D-GMM model for the regression.

Findings

The results show that the current AFI is positively correlated with the firm performance in each of the next four quarters (the following one year). This positive relationship is pronounced for large firms, firms with no large foreign investors, liquid firms and firms listed in the active market. The results suggest that foreign investment might choose well-productive firms already. Also, the current AFI is significantly positively correlated with stock returns in each of the next three quarters. These results suggest that the AFI is informative up to one-year period.

Research limitations/implications

The results suggest that foreign investors (most of them are small) in the Vietnamese market might choose well-productive firms already. However, if the large investors have long-term investment in tangible, intangible, human capital and so on, and lead to a significant increase in firms’ performance is still the limitation of this paper.

Practical implications

The results of this paper may guide investors whose portfolios are composed of stocks with foreign investment.

Originality/value

This paper adds to the literature to enrich the conclusion of a positive relationship between foreign ownership and firm performance.

Abstract

Purpose

The so-called “oil price war” of 2014-2016 took place between several main global oil producers; OPEC (led by Saudi Arabia), Russia and the newcomer; American tight oil or fracking oil. These oil producers were competing against each other over market shares in the global oil market, by maintaining their high oil production rates, even if this led to a decline in oil prices and a reduction in revenues from oil sales. As energy politics need more coverage in International Political Economy (IPE) theory, this paper aims to argue that Saudi Arabia's policies during the oil price war of 2014-2016 reflected a policy of neomercantilism, which is the IPE equivalent of the school of realism in International Relations (IR).

Design/methodology/approach

This paper tests for neomercantilism by testing three of its main definitional components. The first definitional component is that the state, as the political authority, intervenes in the economic decisions. The second component is the primacy of the state interests over business corporate profits, or the primacy of political and security considerations over short-term economic and corporate profit considerations. The third is the zero-sum or relative gains nature of dealings between states. Afterwards, this paper tests for neomercantilism in the Saudi policy by examining how each of these definitional components is reflected in the Saudi policy during the oil price war.

Findings

As energy politics need more coverage in International Political Economy (IPE) theory, this paper argues that Saudi Arabia's policies during the oil price war of 2014-2016 reflected a policy of neomercantilism, which is the IPE equivalent of the school of realism in International Relations (IR).

Originality/value

As energy politics need more coverage in International Political Economy (IPE) theory, this paper argues that Saudi Arabia's policies during the oil price war of 2014-2016 reflected a policy of neomercantilism, which is the IPE equivalent of the school of realism in International Relations (IR).

Abstract

Purpose

Despite volumes of research on the efficient market hypothesis (EMH) over the last six decades, the results are inconclusive as some studies supported the hypothesis, and some studies rejected it. The study aims to examine the market efficiency of the Indian stock market.

Design/methodology/approach

For analysis, nine Bombay Stock Exchange (BSE) broad market indices were selected covering the study period from 01 January 2011 to 31 December 2020. The data collected for this study are daily open, high, low and closing prices of selected indices. The tools used in this study are: (1) unit root test to check the stationarity of time series, (2) descriptive statistics, (3) autocorrelation and (4) runs test.

Findings

The empirical findings of the study reveal that BSE broad market indices do not follow a random walk and Indian stock market is as weak-form inefficient.

Research limitations/implications

The findings from this study provide several avenues for future research. One of the research implications is that anomalies in the statistical results by different academicians in the finance area need to be explained by future researchers.

Practical implications

Investment companies need to understand that extraordinary skills are required to beat the market to make abnormal returns. In an inefficient market where securities do not reflect the complete available information, it is challenging for the investment brokers to convince the customers about the portfolios they recommend to the public that the rate of return would be more than expected.

Social implications

As economic growth is related to the growth in the financial sector, developing countries like India depend on the accuracy of the information. In the presence of asymmetric information, the fluctuations in the stock market would have serious harmful consequences on the economy.

Originality/value

Amid several controversies surrounding the EMH testing, this study is a modest attempt to provide evidence that the Indian stock market is in weak-form inefficient. However, it is essential to link investors' behaviour and trends observed in the financial sector to fully understand the implications of EMH.
