Charlie Hebdo

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.

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.

Transfer of stocks to a more regulated section within the same stock exchange is a quasi-natural experiment that enhances the investor base of companies. The purpose of this paper is to examine for the first time this investor base change and its price-impact. Considering the Japanese Exchange Group merger in 2012 and its structural amendments, the author uses a final sample of 181 firms between 2014-2019. An event study methodology is used to examine the abnormal returns and trading activity in relation to the investor base change proxy. The study also uses robust MM regression analysis to investigate whether the expected price-impact has is temporary or permanent. The results demonstrate that companies that had the largest positive shift in investor base also experienced the largest positive abnormal returns (+ 3.74%) and volume gains. Crucially, the author found no evidence of reversal of this price-impact, inconsistent with the price-pressure hypothesis. Instead, the increase in stock prices caused by section transfer to a more regulated section seems to be permanent.

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.

<p>This paper test the factors explaining of cumulative abnormal returns. To this end, we examined a sample of 137 firms in 2007. We tested event study methodology to measure the cumulative abnormal returns. An event window spans from-10 days to 10 days. In our study, we considered an estimation period from -20 days to -10 days. For the dependent variable, and after the announcement date (date of the general meeting), we try to estimate the cumulative abnormal returns of 1 day, 2 days, 6 days and 8 days. The empirical results of the cross sectional model show that the market reacts negatively because of an increase in profitability, firm size and managerial ownership. The opposite effect is observed for leverage. However, the effect of spending on research and development is not statistically significant.<span style="font-size: 10px;"> </span></p>

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.

The objective of this paper is to investigate whether mergers create value for shareholders in both the short and long term. For this purpose, 120 announcements of mergers that were registered in Italy during the period 1994-2006 among listed companies were examined. The short-term analysis was conducted using the event study methodology in order to estimate the cumulative abnormal returns (CARs) in the time window around the announcement date (-10, +10). In this work, the sample of 120 mergers was divided into two sub-samples: the first considers the mergers that were carried out in all sectors of the economy, and the second focuses only on bank mergers. From the results obtained it would appear that, while the sub-sample of all mergers registered a statistically significant value creation for the shareholders of both the bidder and target companies, values also confirmed by combined analysis, the second sub-sample registered negative values for bidder companies and positive values for target companies. Negative values also seem to be confirmed by the results of the combined analysis both at the date of announcement and throughout the entire period of observation. For the long-term analysis the Buy and Hold Abnormal Returns methodology (BHARs) was used, with which it was possible to observe the returns for three years. In the 36 months following the merger, the portfolio showed a significant destruction of value.

This study aims to examine the spillover effect of right offerings to the industry on the Indonesian Stock Exchange in the period 2009-2016. This study is designed using event study methodology. In total, there are 96 issuing companies (issuers) and 1205 non-issuing companies (non-issuers) used as the sample which was obtained using a purposive sampling technique. The test for information content on the right issues was conducted using standard t-test on the average cumulative abnormal return of issuers and non-issuers in the period t-10 to t+10 around the issuance. The research found positive abnormal returns for issuers in t0 to t+4 but did not confirm the spillover effect to non-issuers over the observed (window) periods. The average cumulative abnormal returns are randomly distributed during the window period. These results confirm the absence of intraindustry effect of right issues on the non-issuers’ performance

The financial sector, because of its catalytic role in the economy, has always been in the eye of the storm in economic difficulties. Due to the pandemic, the stock market had lost about 27 percent by April 2020 and bank nifty has had a lion’s share in pushing the index down to this level. Uncertainty arose as the containment of the disease and the availability of vaccines remain uncertain; this contributed to the plunge in investor confidence. Because of the central role of banks in the development initiatives of the governments, COVID-19 has become a significant threat to the sustainability of the banks globally, especially in developing economies. However, we believe every downfall brings in new opportunities for the investors. Therefore, the present study attempted to study both the gloom and boon and observed that there were short-term abnormal returns to the investors of nifty banks in two different periods - the detection of the first case of COVID-19 in India and the lockdown periods in India. The impacts of both the events are calculated by applying Market and Risk Adjusted model, Market Adjusted Return model and Mean Adjusted Return model. The paper concludes that the impacts were insignificant during the first period and was quite significant in the subsequent period. Nifty banks have earned negative abnormal returns during the pre-lockdown period and positive abnormal returns during post lockdown period which indicates that the markets reacted positively as India implemented the first lockdown.

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

Empirical evidence suggests that a large number of studies support the signaling impact of dividends, but the results are more pronounced in developed markets as compared to emerging markets, where because of the weak form of market efficiency, signaling impact is not well-established. This study tests this hypothesis in Indian capital markets, in terms of signaling impact due to shifts in dividend policy. The study has defined the shift in dividend policy as an increase or a decrease of dividend by 20 percent from the previous dividend payout rate. Standard event study methodology was applied on 129 such events in the selected time period and these events were further classified according to market capitalization. Large-cap stocks displayed the presence of significant abnormal returns in the pre-event period, whereas the mid-cap stocks displayed the same in the post-event period. The results of the small-cap stocks mirrored that of large-cap stocks but they are the only ones in which cumulative average abnormal returns were found to be significantly displaying the lagged response toward the event. The decrease in dividend rate by 20 percent or more did not result in average abnormal returns in either pre-event or post-event window.
