The Impact

PurposeThis study aims to provide evidence of market reactions to organizations' inclusion of people with disabilities. Cases from financial journals in 1989–2014 were used to analyze the impact of actions taken by organizations to include or discriminate people with disabilities in terms of the companies' stock prices.Design/methodology/approachThis research is conducted as an event study where the disclosure of information on an organization's actions toward people with disabilities is expected to impact the organization's stock price. The window of the event was set as (−1, +1) days. Stock prices were analyzed to detect abnormal returns during this period.FindingsResults support the hypotheses that investors value inclusion and reject discrimination. Furthermore, the impact of negative actions is immediate, whereas the impact of positive actions requires at least an additional day to influence the firm's stock price. Some differences among the categories were found; for instance, employment and customer events were significantly more important to a firm's stock price than philanthropic actions. It was observed that philanthropic events produce negative abnormal returns on average.Originality/valueThe event study methodology provides a different perspective to practices in organizations regarding people with disabilities. Moreover, the findings in this research advance the literature by highlighting that organizations should consider policies and practices that include people with disabilities.

Stock Market Reactions

This research deals with stock market reactions of Central Eastern and South Eastern European (CESEE) markets to the COVID-19 pandemic, via the event study methodology approach. Since the stock markets react quickly to certain announcements, the used methodology is appropriate to evaluate how the aforementioned markets reacted to certain events. The purpose of this research was to evaluate possibilities of obtaining profits on the stock markets during great turbulences, when a majority of the participants panic. More specifically, the contrarian trading strategies are observed if they can obtain gains, although a majority of the markets suffer great losses during pandemic shocks. The contributions to the existing literature of this research are as follows. Firstly, empirical research on CESEE stock markets regarding other relevant topics is still scarce and should be explored more. Secondly, the event study approach of COVID-19 effects utilized in this study has (to the knowledge of the author) not yet been explored on the aforementioned markets. Thirdly, based on the results of CESEE market reactions to specific announcements regarding COVID-19, a simulation of simple trading strategies will be made in order to estimate whether some investors could have profited in certain periods. The results of the study indicate promising results in terms of exploiting other investors’ panicking during the greatest decline of stock market indices. Namely, the initial results, as expected, indicate strong negative effects of specific COVID-19 announcements on the selected stock markets. Secondly, the obtained information was shown to be useful for contrarian strategy in order to exploit great dips in the stock market indices values.

This study revisits the market reactions on the dividend payment events, cum-dividend date and payment date, using the event study method. The sample of this study includes all dividend announcements from 2017 to 2018 in the Indonesia Stock Exchange. This study performs various robust statistical tests proposed by Harrington and Shrider (2007), who point out that standard classical t-test is not enough to ensure abnormal return on an event because of the bias due to volatility caused by an event. Using various statistical tests for testing the abnormal return, this study shows that the market indeed reacts to the cum-dividend date and dividend payment date, as well as showing that the classical t-test showing the same conclusion as the other tests.

Building on the literatures on service failure and crisis seriousness, we develop a framework to understand the effects of a specific type of service crisis (i.e., data breaches) and organizational recovery resources on the reactions of the stock market. To do so, we conduct an event study analysis with a sample of 217 data breach announcements, as our empirical context. Our analyses reveal that a firm suffers from negative abnormal stock returns when either the outcome of the breach (e.g., the breach of financial data) or its causal process (e.g., hacker attack) indicates a high level of seriousness. Moreover, considering organizational recovery resources, we find that in the case of financial data breaches, age, size, profitability, liquidity, and brand familiarity are the primary resources that can help a firm’s recovery. For hacker attacks, these organizational recovery resources include size, profitability, and liquidity.

Event Study Methodology

Evaluation of market reaction to regulatory accounting events such as the accounting standards policy setting process has commonly utilized event study methodology. However, this methodology quite often has resulted in inconsistent and conflicting findings due to partial anticipation of the events being examined and due to nonstationarity of the parameters in the estimation model. A multi-regime market model based methodology that allows for the proper treatment of these problems is proposed and is illustrated with an application in the policy setting process for SFAS No. 8.

Stock Market Reactions

This study analyses the difference in stock market reactions to dividend announcement during the pandemic. The thirty constituent stocks of Sensex, the index of Bombay Stock Exchange (BSE), is used for analysis. This allows cross-industry comparison of the market reaction. The study examines stock market reactions covering 44 days around the dividend announcement dates. The primary objective of this study is to understand whether the price adjustment linked to the dividend announcement news during the pandemic was different from the earlier years. This empirical study employs the conventional event study methodology using abnormal returns (ARs) to examine the stock market reaction to dividend announcement. The market reaction to dividend announcement was increasingly positive during the pandemic, compared to previous years. The statistical pooled t-tests showed there was a significant relationship between the pandemic and ARs. The findings also indicate that the difference in the market reaction to dividend announcement was more prominent in services stocks than that in manufacturing. Further, the results also verify the weak-form of efficiency of Indian stock exchange.

This study examines the market reactions to share repurchase announcements made by companies listed on the Johannesburg Stock Exchange from the years 2003 to 2012. The authors use an event study methodology and the Capital Asset Pricing Model to determine if there was an announcement effect when a share repurchase announcement is made. The analyses reveal that consistent with signalling theory and the announcement effect, share repurchase announcements are associated with positive abnormal returns. The average abnormal return and cumulative average abnormal return noted was 0.46% and 3.81%, respectively, for the event period (t-20, t+20). There was an observable trend of declining share prices before the share repurchase announcement. The authors also found no significant evidence that repurchasing firms have market timing ability when executing a share repurchase announcement. From a value investor’s perspective, a share repurchase program conveys a very strong signal of a healthy company
