This study aims to examine the deterrent effect of the Market Abuse Directive (MAD) introduced in the European Union in 2003. The purpose is to evaluate whether the Directive has resulted in significant changes in pre-bid stock price run-ups observed in mergers and acquisitions within the Portuguese, Spanish and Greek stock markets.

The study analyzes a sample of 199 mergers and acquisitions in the aforementioned stock markets. The magnitude of pre-bid stock price run-ups is investigated as an indicator of illegal insider trading. The effects of the MAD, toehold positions of bidders and industry similarity between firms involved in the deals are assessed using statistical analysis.

The study’s findings indicate that the MAD has been ineffective in deterring investors from trading on non-public information. Pre-announcement price run-ups remain significant, suggesting ongoing illegal insider trading practices. Additionally, the research reveals that pre-bid stock price run-ups tend to be lower when bidders have established a larger toehold position in the target and when the firms involved in the deal belong to the same industry.

This study contributes to the existing literature by providing empirical evidence on the ineffectiveness of the MAD in deterring illegal insider trading. The findings highlight the limitations of increasing penalties without an effective monitoring system in place. Furthermore, the study identifies additional factors, such as toehold positions and industry similarity, that influence the magnitude of pre-announcement price run-ups in mergers and acquisitions.

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.

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

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

The study does not use empirical research methodology.

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

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.

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

This paper aims to investigate the trading behavior of insider investors before and after information releases, identifying information-based manipulation in the stock market and the characteristics of companies whose stock prices are manipulated.

This paper employs logit regression method and an event study approach, utilizing hand-collected data from 2010 to 2022, with information categorized into negative and positive types.

The results show no evidence of insider trading or negative information-based manipulation in both high and low transparency firms. However, in highly transparent companies, the Board of Directors (BOD) avoids direct manipulation by using relatives to evade market supervisors. In low transparency companies, both the BOD and family members (FM) exploit positive information to benefit personally by buying shares before releasing favorable news, causing a sharp stock increase, and selling afterward. Continued buying by the BOD and FM also suggests likely positive news announcements.

The characteristics of information-based manipulation in companies, as provided by this study, help individual investors avoid investing in stocks that are highly susceptible to manipulation.

Empirical research on information-based manipulation is scarce due to limited secondary data. Our study uses transaction data from insider investors in a frontier market with low transparency and high information asymmetry. This enables us to analyze information-based stock price manipulation. We identify manipulation by comparing insiders' trading behavior with their market information releases, resulting in stock price fluctuations greater than 5%.

The rise in business activities coupled with free trade liberalisation across countries has entailed an increase in securities transaction as well as insider trading (IT). In fact, IT is characterised by the influence and usage of some prior knowledge concerning sensitive information of a corporate body which results in a financial benefit to the insider trader. The practice of IT is not only unethical but also illegal and this statement is witnessed by the mushrooming of laws across the globe categorising IT as an offence. However, the type of punishment varies in different countries depending on various factors. Consequently, the purpose of this paper is to assess the adequacy and efficiency of IT laws in the context of a developing country being Mauritius.

To achieve the research objective, the Mauritian laws on IT were compared with the corresponding laws of some developed countries like the USA and the UK. As such, a qualitative research method was adopted. In particular, the black letter approach was used to examine the relevant laws of Mauritius, UK and USA on IT. A comparative analysis was conducted concerning IT laws for each country with the view of suggesting recommendations for Mauritian stakeholders to adopt to enhance the existing legal and regulatory framework on IT.

It was found that Mauritian IT laws are largely inspired from both the US and UK corresponding legislation. However, Mauritian laws need to be strengthened by imposing some more severe penalties in terms of fines and terms of imprisonment like the USA has established. The Mauritian Financial Services Commission as the regulator also needs to play a more active role in disseminating particularities of IT laws, offences and penalties to the civil society at large.

At present, this study will be among the first academic writings on the efficiency of IT laws in Mauritius and also, because existing literature is quite scarce on assessing the adequacy of IT legislation in developing countries, this research aims at filling in the gap in literature. The study is carried out with the aim of combining a large amount of empirical, theoretical and factual information that can be of use to various stakeholders and not only to academics.

This study aims to explore the relationship between chief executive officer (CEO) power and stock price crash risk in India. Furthermore, it seeks to analyse how insider trades may moderate the impact of CEO power on stock price crash risk.

A study of 236 companies from the S&P BSE 500 Index (2014–2023) have been analysed through pooled ordinary least square (OLS) regression in the baseline analysis. To enhance the results' reliability, robustness checks include alternative methodologies, such as panel data regression with fixed-effects, binary logistic regression and Bayesian regression. Additional control variables and alternative crash risk measure have also been utilised. To address potential endogeneity, instrumental variable techniques such as two-stage least squares (IV-2SLS) and difference-in-difference (DiD) methodologies are utilised.

Stakeholder theory is supported by results revealing that CEO power proxies like CEO duality, status and directorship reduce one-year ahead stock price crash risk and vice versa. Insider trades are found to moderate the link between select dimensions of CEO power and stock price crash risk. These findings persist after addressing potential endogeneity concerns, and the results remain consistent across alternative methodologies and variable inclusions.

This study significantly advances research on stock price crash risk, especially in emerging economies like India. The implications of these findings are crucial for investors aiming to mitigate crash risk, for corporations seeking enhanced governance measures and for policymakers considering the economic and welfare consequences associated with this phenomenon.

The present study reviews the literature on the history and evolution of investment strategies in the stock market for the period from 1900 to 2022. Conflicts and relationships arising from such diverse seminal studies have been identified to address the research gaps.

The studies for this review were identified and screened from electronic databases to compile a comprehensive list of 200 relevant studies for inclusion in this review and summarized for the cognizance of researchers.

The study finds a coherence to complex theoretical documentation of more than a century of evolution on investment strategy in stock markets, capturing the characteristics of time with a chronological study of events.

There were complications in locating unpublished studies leading to biases like publication bias, the reluctance of editors to publish studies, which do not reveal statistically significant differences, and English language bias.

Practitioners can refine investment strategies by incorporating behavioral finance insights and recognizing the influence of psychological biases. Strategies span value, growth, contrarian, or momentum indicators. Mitigating overconfidence bias supports effective risk management. Social media sentiment analysis facilitates real-time decision-making. Adapting to evolving market liquidity curbs volatility risks. Identifying biases guides investor education initiatives.

This paper is an original attempt to pictorially depict the seminal works in stock market investment strategies of more than a hundred years.

The purpose of this study is to propose a world-class good governance ethics framework that leads to better corporate performance. ethics among managers, executives and members of the board of directors working in public-listed companies brings grave concern because of the increasing number of criminal acts reported by the Security Commission of Malaysia.

This study introduces a world-class good governance ethics framework for curbing criminal acts in public-listed companies in Malaysia. This study used a mixed method to gather data, and the methods used are appropriate for answering the research questions based on the World-Class Good Governance Ethics framework.

The finding of this study reveals high expectations for a corporate organization to improve individual and team performance while undertaking their corporate responsibilities, and a matter of choice, to adopt world-class good governance ethics in their policies and practices.

This study could be a reference for corporate management to regulate policies monitoring management's and employees' conduct at the workplace. This study's theoretical and practical significance would guide the stakeholders in corporate management to regulate governance policies based on the right ethical values and promote personalities with high integrity in management conduct.

This study promotes a world-class good governance ethics framework in curbing criminal acts for better corporate performance. This new framework is formulated based on the concept of a caliph and other essential elements envisaged by the Quranic verses.

This chapter analyzes how the macro-environment determines corporate dividend decisions. First, political factors including political uncertainty, economic policy uncertainty, political corruption, and democracy may have two opposite effects on dividend decisions. For example, firms learn democratic practices to improve their corporate governance, but dividend policy may be the outcome of strong corporate governance or the substitute for poor corporate governance. Second, firms in countries of high national income, low inflation, and highly developed stock markets tend to pay more dividends. A monetary restriction (expansion) reduces (increases) dividend payments, as economic shocks like financial crises and the COVID-19 may negatively affect corporate dividend policy through higher external financial constraint, economic uncertainty, and agency costs. On the other hand, they may positively influence corporate dividend policy through agency costs of debt, shareholders' bird-in-hand motive, substitution of weak corporate governance, and signaling motive. Third, social factors including national culture, religion, and language affect dividend decisions since they govern both managers' and shareholders' views and behaviors. Fourth, firms tend to reduce their dividends when they face stronger pressure to reduce pollution, produce environment-friendly products, or follow a green policy. Finally, firms have high levels of dividends when shareholders are strongly protected by laws. However, firms tend to pay more dividends in countries of weak creditor rights since dividend payments are a substitute for poor legal protection of creditors. Furthermore, corporate dividend policy changes when tax laws change the comparative tax rates on dividends and capital gains.

In past decades, artificial neural network (ANN) models have revolutionised various stock market operations due to their superior ability to deal with nonlinear data and garnered considerable attention from researchers worldwide. The present study aims to synthesize the research field concerning ANN applications in the stock market to a) systematically map the research trends, key contributors, scientific collaborations, and knowledge structure, and b) uncover the challenges and future research areas in the field.

To provide a comprehensive appraisal of the extant literature, the study adopted the mixed approach of quantitative (bibliometric analysis) and qualitative (intensive review of influential articles) assessment to analyse 1,483 articles published in the Scopus and Web of Science indexed journals during 1992–2022. The bibliographic data was processed and analysed using VOSviewer and R software.

The results revealed the proliferation of articles since 2018, with China as the dominant country, Wang J as the most prolific author, “Expert Systems with Applications” as the leading journal, “computer science” as the dominant subject area, and “stock price forecasting” as the predominantly explored research theme in the field. Furthermore, “portfolio optimization”, “sentiment analysis”, “algorithmic trading”, and “crisis prediction” are found as recently emerged research areas.

To the best of the authors’ knowledge, the current study is a novel attempt that holistically assesses the existing literature on ANN applications throughout the entire domain of stock market. The main contribution of the current study lies in discussing the challenges along with the viable methodological solutions and providing application area-wise knowledge gaps for future studies.

This study aims to explore the impact of systematic liquidity risk on the averaged cross-sectional equity return of the Indian equity market. It also examines the effects of illiquidity and decomposed illiquidity on the conditional volatility of the equity market.

The present study employs the Liquidity Adjusted Capital Asset Pricing Model (LCAPM) for pricing systematic liquidity risk using the Fama & MacBeth cross-sectional regression model in the Indian stock market from January 1, 2012, to March 31, 2021. Further, the study employed an exponential generalized autoregressive conditional heteroscedastic (1,1) model to observe the impact of decomposed illiquidity on the equity market’s conditional volatility. The study also uses the Ordinary Least Square (OLS) model to illuminate the return-volatility-liquidity relationship.

The study’s findings indicate that the commonality between individual security liquidity and aggregate liquidity is positive, and the covariance of individual security liquidity and the market return negatively affects the expected return. The study’s outcome specifies that illiquidity time series analysis exhibits the asymmetric effect of directional change in return on illiquidity. Further, the study indicates a significant impact of illiquidity and decomposed illiquidity on conditional volatility. This suggests an asymmetric effect of illiquidity shocks on conditional volatility in the Indian stock market.

This study is one of the few studies that used the World Uncertainty Index (WUI) to measure liquidity and market risks as specified in the LCAPM. Further, the findings of the reverse impact of illiquidity and decomposed higher and lower illiquidity on conditional volatility confirm the presence of price informativeness and its immediate effects on illiquidity in the Indian stock market. The study strengthens earlier studies and offers new insights into stock market liquidity to clarify the association between liquidity and stock return for effective policy and strategy formulation that can benefit investors.
