The purpose of this paper is to investigate the extent of directors breaching the reporting requirements of the Australian Stock Exchange (ASX) and the Corporations Act in Australia. Further, it seeks to assess whether directors in Australia achieve abnormal returns from trades in their own companies.

Using an event study approach on an Australian sample, abnormal returns for a range of situations were estimated.

A total of 13 (seven) per cent of own‐company directors trades do not meet the ASX (Corporations Act) requirement of reporting within five (14) business days. Directors do achieve abnormal returns through trading in shares of their own companies. Ignoring transaction costs, outsiders can achieve abnormal returns by imitating directors' trades. Analysis of returns to directors after they trade but before they announce the trade to the market shows that directors are making small but statistically significant returns that are not available to the market. Analysis of returns to directors subsequent to the ASX reporting requirement up to the day the trade is reported shows that directors are making small but statistically significant returns that should be available to the market.

Future research should investigate the linkages between late reporting by directors and disadvantages to outside shareholders and the implementation of internal policies implemented to mitigate insider trading.

Market participants should remain vigilant regarding the potential for late/non‐reporting of directors' trades.

Uncovering breaches of reporting regulations are particularly important given that directors tend to purchase (sell) shares when the price is low (high), thereby achieving abnormal returns.

The purpose of this paper is to investigate the effect of bond issuance announcements on share price returns in three emerging markets and examine the characteristics of bond issues that affect the abnormal share price returns of the company.

This study employs event study, correlation and multiple regression techniques to attain the research objectives. The authors test hypotheses on 105 public listed companies from Malaysia, Singapore and Thailand, during the period of 2008–2014.

The findings show positive cumulative average abnormal returns resulting from the announcement of corporate bond issuance for Malaysia, Singapore and Thailand. The results reveal that there is a significant effect of bond issuance announcements on share price returns. The results also disclose that the market is not efficient at its semi-strong form as proposed by the market efficiency hypothesis.

The results provide better references for fund managers and investors in capital markets to take advantage of the abnormal returns resulting from bond issuance announcements.

This research investigates the effect of mergers and acquisition (M&A) transactions in the pharmaceutical sector. The study assesses the short-term value creation or destruction for shareholders of pharmaceutical companies involved in M&A activities on the acquiring side.

The empirical analysis is carried out by applying the event study methodology in order to define the cumulative abnormal return for each transaction observed. Then, the correlations between abnormal returns and economic metrics are determined building a multiple regression model. These metrics refers to the acquirer, target or to the deal itself.

Evidence show a short-term value creation for shareholders of pharmaceutical companies involved in M&A transactions on the acquiring side. On the one hand, the analysis suggests a negative correlation between the value creation and the acquiring firm's level of indebtedness. On the other hand, the value creation is positively correlated with target's metrics such as Return on Equity (ROE), Return on Assets (ROA) and Research and Development (R&D) intensity. Value creation is also tied to deal-specific characteristics regarding the cash used in the transaction and the comparative extent of the deal.

This analysis allows to predict returns around an announcement day considering the described indicators of value creation or destruction. M&As play a key role in the strategy implementation as reaction to exogenous shocks and endogenous needs.

This study enriches the literature of corporate finance applied to the pharmaceutical sector. Indeed, this industry is gaining increasing relevance in the M&A panorama. Thus, the related dynamics need to be assessed considering the uniqueness of the pharmaceutical sector in terms of regulation, stakeholders and social impact.

Investors in Hong Kong tend to overreact to good news but not to bad news in the short run. ‘Winner’ stock portfolios making abnormal gains on the event day tend to make abnormal losses in the subsequent test period. On the contrary, abnormal losses persist in the test period for the loser stock portfolios. This may be attributable to the speculative nature of the Hong Kong market and thin trading of small‐sized stocks. Some evidence of small firm effect is found in this study, but price overreactions are more apparent with large size portfolios. Apart from size, asymmetrical investors' response to good news and bad news also drives stock prices to behave differently after experiencing abnormal gains or losses. For winner stocks, larger abnormal gains on day 0 are followed by larger abnormal losses in the subsequent 10‐day period. Whereas for loser stocks, larger abnormal losses are followed by larger but further losses in the test period. Last but not least, symptoms of weekly price seasonally are found amongst the abnormal return patterns in this study.

Certification information published by a company will be responded by the market. Therefore, the purpose of this study is to examine the impact of ISO 9001 certification on the stock market reaction as indicated by stock returns reaction of companies in Indonesia.

This study used event study method with the period of 13 days. It consists of 6 days before and after ISO 9001 certification announcement and 1 day at the time of the event. It analyzed by using pair sample t-test and one sample t-test. The stock return data is obtained from companies that are ISO 9001 certified and it tested for their stock reactions before and after the certification.

The results of empirical research showed that the average and companies cumulative abnormal returns in Indonesia react quickly and positively on the first day after ISO 9001 certification announcement. This study proved the differences between abnormal returns before and after the ISO 9001 certification announcement period.

The company's success in implementing ISO 9001 will have an impact on investment in the capital market with a positive response from stock market players. The implication of this study is the further research can examine directly the impact of ISO 9001 implementation on investor behavior in the capital market.

Based on the development of the literature review, this is the first study which examined the impact of ISO 9001 certification announcement on investor reactions in the short term. Therefore, companies in Indonesia need to implement a quality management system for investors in Indonesia.

This study examined the impact of the Glasgow Climate Pact on the abnormal returns of global clean energy stocks. Further, this study examines which country-specific and firm-specific variables drive the cumulative abnormal returns (CARs) of clean energy stocks.

The authors used the event study method and cross-sectional multivariate regression model. The clean energy stocks in this study are limited to 81 constituent firms of the S&P Global Clean Energy Index across 17 nations. The final sample includes 80 firms and the sample period ranges from January 26, 2021, to December 07, 2021.

The study finds that the Glasgow Climate Pact negatively affects the stock returns of clean energy firms. Moreover, the climate change performance index (CCPI) positively impacts cumulative abnormal returns (CARs), signifying that clean energy investors react positively to firms in nations with good CCPI scores. The environmental, social and governance (ESG) measure for the shorter window (−1, +1) exhibited a negative relationship with CARs. The firm-specific variables (BTM, stock liquidity, size and past returns) exhibit a negative relationship with CARs in different event windows.

The authors use the CCPI as a proxy for the stringency of environmental policies in any nation. The authors extend the existing literature by employing firm-specific variables and supporting previous findings. Their findings have policy implications for clean energy investors, policymakers and other market participants.

Climate risks impact the global financial market, so the findings have implications for global regulatory bodies. Currently, there are bankruptcy cases due to climate risks. Because financial markets must play a critical role in shifting the economy toward a green one, regulators can use the cross-sectional drivers of this study to shape policy. It is also critical for regulators to reduce stock price volatility in the event of the implementation of environmental regulations and improve environmental disclosures by publicly traded companies. Furthermore, governments are interested in researching the effects of environmental regulations to protect stakeholders' interests. These regulations significantly impact emerging markets because they lack the same solid institutional frameworks as developed markets.

The authors provide evidence that firms with better ESG scores and larger firm sizes have experienced fewer abnormal returns, as these firms have stable financial and non-financial fundamentals. This timely study on the ongoing regulatory shift in environmental policy will help investors, policymakers, firms and other stakeholders make relevant decisions.

This study examines share price reaction to the enrollment by companies in the Children’s Food and Beverage Advertising Initiative. We find that, on average, in the month of enrollment, shareholders of companies that join the CFBAI experience abnormal return of −3% and so do the shareholders of the immediate competitors that do not join the initiative. However, over the subsequent five years, while the shareholders of companies enrolled in the initiative experience an average abnormal return of +16.6%, that of non-enrolled competitors experience a further abnormal return of −34%. The abnormal returns for the two groups (at the time of enrollment and over the subsequent five years) are uncorrelated and so benefitting at the expense of competitors does not appear to be the motive for enrolling in the CFBAI. The study also provides comparison of number of employees and other important financial ratios before and after enrollment in the CFBAI for the two groups.

This paper investigates if investors consider legal insider trading data while making investment decisions. If any investment decision is based on insider transactions, then it will result in abnormal stock characteristics. The purpose of this paper is to investigate if insider trading affects stock characteristics like price, return and volume. The paper further investigates the effect on stock characteristics after the trade of different types of insiders and the relationship between abnormal return and abnormal volume.

The study uses the event study method to measure the abnormal price, return and volume. Two-stage least square regression is used to investigate the relationship between abnormal return and abnormal volume.

The insider trades affect price, return and volume. The results are identical for both buy and sell transactions. The trades of different types of insiders have diverse effects on stock characteristics. The trades of substantial shareholders give rise to the highest abnormal price and return, whereas the promoters' trades result in the highest abnormal volume. No relationship is detected between abnormal return and volume.

A novel method to calculate the abnormal price is proposed. The effect of trading of all types of insiders on stock characteristics is analyzed. The relationship between abnormal return and abnormal volume, after an insider trade, is investigated.

The purpose of the study is to examine the implementation of Enterprise Resource Planning (ERP) on the announcement of firms’ stock market returns. The authors investigate the stock market reaction on ERP adopters and ERP vendor firms in the USA during 1990-2010. The study examines firm- and non-firm-specific factors including the role of the financial analyst in explaining the determinants of the cumulative abnormal returns surrounding ERP announcements of adopting firms.

Data on ERP system implementation announcements of 112 US firms for the period 1990-2010 were collected from LexisNexis Academics. The authors estimate abnormal returns using an event study methodology for each of the ERP announcements based on the Fama–French three-factor and Fama–French-momentum four-factor models for ERP adopters and for vendors. Subsequently, the authors explain the determinants of abnormal returns in terms of firm and non-firm behavioral variables using cross-section regression methodology.

The empirical results establish that cumulative abnormal returns of US firms on ERP system implementation announcements are positive, signifying that investors view this decision positively and that ERP implementation contributes to enhanced business value in the future. On the contrary, the impact of ERP announcements on vendors is muted. We find that the extent of financial analyst coverage negatively impacts abnormal returns, while the extent of stock market liquidity has a significant positive impact on abnormal returns.

This study is based on a sample of ERP implementing firms which are predominantly large firms and on technology provided by one vendor that is predominantly monopolistic.

Firms’ attitudes toward implementing an ERP system for future efficiency gains and the implications on the stock market (and indirectly, on the cost of equity of adopters) provide valuable insights for firms and stock markets.

This study brings clarity to the debate on stock market impacts of ERP implementation announcements – stock markets cheer such announcements. The study also contributes to the literature by examining firm-specific factors (such as performance, size and leverage) and non-firm-specific factors (such as market risk and analyst coverage) in explaining the determinants of abnormal returns of firms announcing ERP investment.

The purpose of this paper is to investigate a unique sample of lottery-like stocks and contextualize their short-run price behavior with respect to behavioral principles.

The authors conduct a short-run event-study of the abnormal returns for stock market investments in Australian small-cap oil and gas (O & G) explorers centered on the drilling commencement (spudding) of 157 wildcat oil or gas wells drilled between January 2000 and June 2010.

Small-cap stock market investments associated with newly spudded wildcat O & G wells are negative NPV gambles rather than fair (zero NPV) investments. Once a wildcat well is spudded, the 30-day expected abnormal return is 6-8 percent: wealth-maximizing stockholders are advised to sell upon news of spudding, but gamblers may wish to hold on for the chance of a 10.6 percent 30-day average abnormal return (if the well is not plugged and abandoned). In the lead-up to each gamble the authors observe a significant pre-spudding stock price run-up on average, perhaps indicative of positively affected investors aroused by an easily imagined successful wildcat gusher as per evidence on the influence of image and affect on investors’ decisions (MacGregor et al., 2000; Loewenstein et al., 2001; Rottenstreich and Hsee, 2001; Peterson, 2002).

The wildcat drilling events considered in this paper are lottery-like by nature, and spudding represents the distinct moment when the gamble is unambiguously on, following shortly on from which investors either strike it lucky or strike out. The specifically small-cap wildcatters are typically heavily vested in one well at a time, therefore the sample stocks are uniquely lottery like. This differs from other studies which infer the lottery-like nature of their sample stocks from characteristics such as price and idiosyncratic volatility.
