Limit Effect

Purpose The purpose of this paper is to re-examine the effectiveness of price limits on stock volatilities in China over a more recent time period spanning from 2007 to 2012. The motivation stems from the fact that very high stock market volatilities are observed in China and we are sceptical of the volatility mitigating effect claimed by advocates of price limits. Design/methodology/approach The effectiveness of price limits on volatilities is examined using an event study methodology and within an expanded framework of volatility-volume relationships. The sample stocks include the 300 component stocks of the CSI300 Index. Findings Both event study and regression analysis suggest that price limits exaggerate market volatilities by causing volatility spillovers. The destabilising effect is much more pronounced for small firm stocks and when the market falls. In addition to the informational source of volatilities (represented by volume), price limits create another non-trivial frictional source of volatilities in China’s stock market. Originality/value This research is the first to re-examine the price limit effect in China’s stock market in an expanded framework of volatility-volume relationships. It identifies price limits, in addition to information, as another non-trivial frictional source of volatilities. The findings derived from a recent sample period confirm the conventional view of inefficiency of price limits raised by Fama (1989) and provide evidence in support of the pervasive trend of stock market deregulations.

Event Study Methodology

Purpose This study aims to examine the impact of voluntary adoption of integrated reporting on the stock prices of firms in Japan. Design/methodology/approach The event study methodology was used to analyze the stock market reactions to voluntary integrated report (IR) publication. Abnormal returns were estimated for 1,602 observations of 490 firms publishing IRs in Japan using the market model. The t-test, the Boehmer et al., 1991 test and the generalized sign test examined the significance of the cumulative average abnormal returns (CAARs). Findings The study reveals that the stock market reacts positively to voluntary IR publication by firms, especially in 2019 and 2015. Additionally, it reveals a tendency for higher CAARs around IR publication dates than around corporate social responsibility report publication dates, especially in 2016 and 2015. Research limitations/implications The limitations of this study include the possibility of self-selection bias and omitted variable bias. Practical implications This study suggests that firms can earn higher abnormal returns in the stock market through environmental, social and governance (ESG) disclosure in IRs, corroborating the recently rising investor interest in voluntary integrated reporting in Japan. Originality/value This study contributes to the literature on the value relevance of voluntary adoption of integrated reporting by providing evidence of firms achieving significantly positive abnormal returns around voluntary IR publication dates. There is no published analysis on this topic using multitudes of sample firms using the event study methodology.

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.

The Impact

Purpose Before introducing new products, companies make announcements regarding the launch of the product which influences stock market yields of the announcing companies. Information content of the new product announcement has never been an exclusive focused stream of research. Therefore, an assessment of the impact of the content characteristics of the new product announcement on the shareholder value and the impact of source credibility (spokesperson) in making such announcements is a major gap in the existing literature. The paper aims to discuss these issues. Design/methodology/approach First, the standard event study methodology has been employed on the sample to measure the abnormal gains/losses accruing to the announcing firms. Second, moderated regression analysis (MRA) is employed to identify the characteristics of the new product announcement and to check the role of the spokesperson in creating shareholder value. Findings The results of the event study indicate that the abnormal returns are generated during the new product announcement. The results of MRA disclose the variables having a positive and a significant influence on the effective returns of the announcing companies. Likewise, the role of the spokesperson has come out brightly as a credible communicator. Originality/value The research provides a direction to the announcing companies regarding the content of the announcement leading to a positive perception among the investing community. Likewise, it also provides direction to the investor community about the characteristics of the announcement content they give weight age in forming a perception of strength in evaluating the new product announcement, to which they are largely unaware.

Fractional Differencing

Purpose This work aims to explore the behavior of stock market prices according to the autoregressive fractional differencing integrated moving average model. This behavior will be compared with a measure of online presence, search engine results as measured by Google Trends. Design/methodology/approach The study sample is comprised by the companies listed at the STOXX® Global 3000 Travel and Leisure. Google Finance and Yahoo Finance, along with Google Trends, were used, respectively, to obtain the data of stock prices and search results, for a period of five years (October 2012 to October 2017). To guarantee certain comparability between the two data sets, weekly observations were collected, with a total figure of 118 firms, two time series each (price and search results), around 61,000 observations. Findings Relationships between the two data sets are explored, with theoretical implications for the fields of economics, finance and management. Tourist corporations were analyzed owing to their growing economic impact. The estimations are initially consistent with long memory; so, they suggest that both stock market prices and online search trends deserve further exploration for modeling and forecasting. Significant differences owing to country and sector effects are also shown. Originality/value This research contributes in two different ways: it demonstrate the potential of a new tool for the analysis of relevant time series to monitor the behavior of firms and markets, and it suggests several theoretical pathways for further research in the specific topics of asymmetry of information and corporate transparency, proposing pertinent bridges between the two fields.

The Impact

PurposeThis paper explores how a firm's public stand on a social-political issue can be a salient signal of the firm's values, identity and reputation. In particular, it investigates how boycott participation–conceptualized as a cue of a corporation's stand on important social-political issues–may affect the stock market valuation of that corporation, as well as how corporations legitimise their stand on the issues.Design/methodology/approachThe authors employ a mixed-methods design that uses both qualitative techniques (content analysis) and quantitative methods (event study methodology) to examine a sample of US firms who participated in a boycott campaign that sought to call attention to issues of hate speech, misinformation and discriminatory content on social media platform Facebook.FindingsFindings from the qualitative content analysis of company statements show that firms legitimise their stand on, and participation in, the boycott by expressing altruistic values and suggesting to stakeholders that their stand aligns not only with organizational values/convictions but also with the greater social good. Importantly, the event study results show that firms who publicly announced their intention to participate in the boycott, on average, earn a statistically significant positive abnormal stock return of 2.68% in the four days immediately after their announcements.Research limitations/implicationsFindings relate to a specific case of a boycott campaign. Also, the sample size is limited and restricted to US stocks. The signalling value of corporate social advocacy actions may vary across countries due to institutional and cultural differences. Market reaction may also be different for issues that are more charged than the ones examined in this study. Therefore, future research might investigate other markets, use larger sample sizes and consider a broader range of social-political issues.Practical implicationsThe presence of significant stock price changes for firms that publicly announced their decision to side with activists on the issue of hate propaganda and misinformation offers potentially valuable insights on the timing of trades for investors and arbitrageurs. Insights from the study also provide a practical resource that can be used to inform organizations' decision-making about such issues.Social implicationsTaking the lead to push on social-political issues, such as hate propaganda, discrimination, among others, and communicating their stands in a way that speaks to their values and identity, could be rewarding for companies.Originality/valueThis study provides novel evidence on the impact that corporate stances on important social-political issues can have on stock market valuation of firms and therefore extends the existing related research which until now has focused on the impact on consumer purchasing intent and brand loyalty.

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.

Stock Price Reaction

PurposeVery little is known about the effect of dividend announcements on stock prices in Nigeria, despite the country’s unique institutional environment. The purpose of this paper is, therefore, to provide empirical evidence on this issue by investigating the stock price reaction to cash dividends by companies listed on the Nigerian Stock Exchange.Design/methodology/approachStandard event study methodology, using the market model, is employed to determine the abnormal returns surrounding the cash dividend announcement date. Abnormal returns are also calculated employing the market-adjusted return model as a robustness check and to test the sensitivity of the results toβestimation. The authors also examine the interaction between cash dividends and earnings by estimating a regression model where announcement abnormal returns are a function of both dividend changes and earnings changes relative to stock price.FindingsThe study find support for the signaling hypothesis: dividend increases are associated with positive stock price reaction, while dividend decreases are associated with negative stock price reaction. Companies that do not change their dividends experience insignificant positive abnormal returns. The results also suggest that both dividends and earnings are informative, but dividends contain information beyond that contained in earnings.Research limitations/implicationsThe sample for the study includes only cash dividend announcements occurring without other corporate events (such as interim dividends, stock splits, stock dividends, and mergers and acquisitions) during the event study period. The small firm-year observations may limit the validity of generalizations from these conclusions.Practical implicationsThe findings are useful to researchers, practitioners and investors interested in companies listed on the Nigerian stock market for their proper strategic decision making. In particular, the results can be used to encourage transparency and good governance practices in the Nigerian stock market.Originality/valueThis paper adds to the very limited research on the stock market reaction to cash dividend announcements in Nigeria; it is the first of its kind employing a unique cash dividends data.

South–South cooperation has been on the rise in recent years. One of the latest examples is the China–Pakistan Economic Corridor (CPEC) proposed by the Chinese and Pakistani governments in 2013. Using event study methodology, this article examines the impact of events and announcements associated with CPEC on the Pakistan Stock Exchange in Pakistan and the Shanghai Stock Exchange in China. The first key finding of this article is that the initial announcement associated with CPEC had stronger and positive short-term impact on the Pakistan Stock Exchange in comparison with the impact of subsequent CPEC events on the stock market. The second key finding is that the short-term impact of the CPEC initial announcement was stronger on the Pakistan Stock Exchange than on the Shanghai Stock Exchange, possibly due to the substantial difference in the size of the two economies. The empirical results of this article have important implications for investors, corporations and regulators to the Global South.
