The present study seeks to critically evaluate the most extensively employed technique – event study methodology, employed to capture the returns generated from M&A events on the wealth status of shareholders. Notwithstanding the popularity of the technique, authors in this paper argue that conceptual bases on which the methodology is founded is flawed. In the light of the extensive limitations attributable to event study methodology, there exists an urgent need to suggest improvement in the conceptual framework of the traditional method capable of lending application to capture the wealth effects of M&A events. The authors believe that application of such a modified approach will be much more salvageable as the results derived therefrom will command greater credibility as well as reliability. In order to highlight the inherent limitation of the event study approach, the authors have used the sample of Indian Banking M&A events retrieved from the M&A data available at etintelligence.com . Given the conceptual flaws of the event study approach, the authors argue that researchers must exercise great caution while commenting on the t-statistic observed for CAR (Cumulative Abnormal Returns) values as the statistical insignificance could be arising more out of the conceptual deficiency of the event study approach than pointing towards the neutral impact of an M&A event on the wealth status of the shareholders.

Increasing COVID-19 cases has not only impacted health and day-to-day lives of people, but it has also had a material effect on India’s economic growth. Stock returns of various sectors are evidence of a country’s stagnated growth but the healthcare and pharmaceutical sector might be affected in a different manner. The purpose of this paper is to find out how has this pandemic has impacted the healthcare and pharma stocks. Daily closing prices of sector specific indexes for 233 days ranging from 15 May 2019 to 24 April 2020 have been taken to compare different sectors with our test sector, on the basis of different criteria. This study has applied the widely used event study methodology on our test sector; calculated abnormal returns, cumulative abnormal returns and also tested their significance. Event study approach suggests that there have been significant abnormal returns and cumulative abnormal returns in our test sector (healthcare and pharmaceutical sector) over the event window, though while comparing it with other sectors through another econometric model, the returns are not statistically significant and do not explicitly indicate the same.

AbstractThe article aims at pointing out the differences in market reactions regarding the announcement of an investment of selected Sovereign Wealth Funds in companies listed on the London Stock Exchange. The research sample consists of 796 market transactions made by four selected Sovereign Wealth Funds. The author employed event study methodology to calculate the average abnormal returns and cumulative abnormal returns for each fund in subsamples. The empirical findings suggest that investors react differently to the information about a fund’s investment. To the best of the author’s knowledge, the literature does not provide any answer as to how the market reacts to information disclosure of individual funds. Therefore, this paper bridges the gap in the literature within this field.

The objective of this study is to assess the share price reactions to smoking ban fatwa on Indonesia tobacco’s company. We expect that the smoking ban fatwa in the world’s largest Muslim population will hit the tobaccos industry revenues, lower tobacco’s company profit and eventually affect the share price of those firms. We use event study methodology and standard market model to calculate abnormal returns of the tobacco’s firms related to the news of smoking ban fatwa. Our study failed to find a statistically significant effect of smoking ban fatwa on tobacco’s firm stock market return. It suggests that the investors do not see the fatwa as a factor that may control the tobacco consumption in Indonesia – thus it may not affect the tobacco’s firm revenues and profit in the future

Abstract Over the last decades, terrorism has become a global phenomenon to which every society is exposed from time to time. Terrorist attacks can have many economic consequences that may affect a number of sectors, including the capital market. The main goal of this paper is to examine the reaction of the CAC40 index to one terrorist attack, mainly “Charlie Hebdo” using an event study methodology. By calculating the abnormal returns and the cumulative abnormal returns in the event period, the results obtained show no significant abnormal returns on the day of the terrorist attack suggesting that the market had directly absorbed the effect of the attack. Thus, the findings suggest that the French market is semi-strong efficient. Investors can rely neither on past information nor on publicly available information to make abnormal profits.

This study investigates the impact of COVID-19 pandemic on daily stock returns in Kuwait Stock Market (KSE) over the period from 28 March to 20 April 2020. By applying the event study methodology (ESM) approach, the results reveal that the pandemic has positively impacted stocks of banks, consumer goods and telecommunications sectors. However, oil & gas, real estate, financial, basic materials, industrials, consumer services, and insurance stocks have been negatively impacted by the pandemic. The COVID-19 pandemic's most negatively affected are services and financial stocks. The cumulative average abnormal returns (CAAR) of all sectors were affected negatively by the COVID-19 pandemic.

<p>We study the impact of dividend policy on the stock return by investigating reaction of the stock price on the dividend announcement date and the ex-dividend date.<strong> </strong>In order to achieve this goal, a sample comprising 1962 observations of dividend-related events from 432 listed companies in Vietnam during the period 2008 to 2015 is chosen to analyze and the event study methodology is used to estimate abnormal returns to the shares around the announcement date and the ex-dividend date. Our results clearly show that the effect of dividend announcement on the stock return is positive around the announcement date. In addition, the stock price moves up as long as the ex-dividend date approaches and then starts decreasing from this date onwards.</p>

AbstractThis paper observes the short-run effects of stock market index composition changes on stock returns on the Zagreb Stock Exchange (ZSE). In that way, event study methodology is employed in order to estimate abnormal returns and compare them amongst three subsets of stocks: those leaving the market index, those entering it, and constantly included stocks. The research included 14 regular and extraordinary revisions of the market index in the period from January 2nd, 2015 until March 21st, 2018. The results have confirmed two research hypotheses: stock exclusions from the market index have a negative effect on stock returns on the ZSE, which is consistent with the price pressure hypothesis; and there exist asymmetric effects of index composition changes on stock returns. This is the first study of this kind on the Croatian stock market, thus more questions need to be answered in future research.

Recent years have witnessed phenomenal growth in both the number and size of US based international equity mutual funds. While the benefits of international diversification are well documented in the literature, empirical research relating to the performance of international mutual funds has been limited and contradictory. The purpose of this study is to examine the impact of political risk on the risk-adjusted returns of international mutual funds using a modified event study methodology. More specifically, the dummy variable event study methodology using portfolios rather than individual funds is used. This methodology addresses the problems of multiple event days and calendar clustering. The macro political risk event of interest is the Iraqi invasion of Kuwait. Results of the study suggest that shareholders of international equity mutual funds earn significant abnormal returns in the face of political turmoil.

This study attempts to examine the stock behaviour of acquirer banks during pre and post-merger and acquisition (M&A) announcement period in the Indian banking sector. Data of M&A events that took place in the Indian banking sector during 2000-2018 was collected from the prowessdx database. The sample consisted of 31 merger and 351 acquisition announcements during 2000-2018 in the Indian Banking sector. Stock prices of sample banks were extracted from the NSE for an event window of -10 to +10 days and the event study methodology was used for analysis. The results suggest that shareholders of Indian acquirer banks generate small and insignificant abnormal returns from M&A deals. Return variability was also noticed from the curvy jumps in the average abnormal spread of returns during the announcement period. Whereas, the average abnormal change in liquidity witnessed a sharp hike on day 0 i.e. the date of deal announcement and it remained negative throughout the post-deal period. KEYWORDS: Mergers and Acquisitions, Stock Return, Stock Volatility, Stock Liquidity, Event Study Methodology.

Event Study Methodology

To validate the existence of abnormal returns, the most of empirical studies use the event study methodology which examines the behavior of firms’ stock prices around corporate event. However, this methodology was been the source of several limits. Some defenders of efficiency theory assert that the abnormal returns are due to the event study methodology failures and econometric problems. However, partisans of behavioral finance demonstrate that the abnormal returns are due to psychological bias. The main purpose of this paper is to verify if the abnormal returns resulting from the event study methodology are due to econometric problems or to psychological bias generated by irrational investors’ reactions. For the econometric bias, five problems are studied: the choice of market index; the missing observations; the abnormal returns normality, joined hypothesis; and the variance volatility in the event window. Results show that abnormal returns are far from being due to the event study methodology failures and econometric bias. For the psychological problems, based on trading volumes, the results show negative and significant abnormal returns (investors’ under-reaction); a strong positive correlation between abnormal returns and abnormal trading volumes and a significant causal sense between them. So, abnormal returns are due to psychological bias
