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.

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.

The aim of this study is to comparatively analyze the backtest performances of trading disciplines applied in various portfolio baskets (Bist 30, 50 and 100) for different investment periods (short term – ytd and long term). According to the results of the analysis, it has been determined that in all trading disciplines, the investor has a higher return than the benchmark indicator in a 5-year term, that is, they can earn abnormal returns. Also, the return in the 5-year term is much higher than the 1-year and YTD returns. In the P / E & MA model, the Bist - 50 index in the 5-year period and the Bist - 100 index in the 1-year period provide the maximum return, while according to the P / E model, the Bist-30 and Bist -50 indices provide optimum returns in all maturity options. Based on these findings, it can be expected that if the trading disciplines used in this study are applied in a long term such as 5 years and on the portfolio basket consisting of Bist-30 and Bist-50 industrial stocks, it will maximize returns. In terms of risk and return, in YTD period, the sharpe and treynor ratios of the model portfolio formed in all trading disciplines except M /B trading discipline were lower than in 1 year in the 5-year investment period. This situation arose due to the increased risk of the portfolio as a result of the extended maturity and is in line with our expectations.

Barron's is a weekly financial magazine published by Dow Jones. It’s considered America's premier financial weekly. Every week, Barron’s magazine will include a section “Research Reports,” which contains the analysts’ recommendations. Using event study methodology and market model as a benchmark, we calculate abnormal returns to ascertain the impact of the recommendations published in the Research Reports. We find that there are no statistically significant long-term abnormal returns associated with the published recommendations in Barron’s.

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 present study analyzes the short- and long-term performance of UK financial acquiring firms by examining a sample of 40 takeovers over the period 19962007. In particular, it investigates i) the short- and long-term stock return performance of these acquiring firms and ii) the relation between their short-term abnormal return around the announcement date of takeovers and their long-term performance. The event study methodology shows that bidders experience significant short-term wealth destruction. In contrast, both the buy-and-hold abnormal returns and bidders portfolio return approaches indicate positive and significant wealth effects over the long run. Business cycle analysis shows that acquirers obtain significantly higher returns during downward financial market cycles. Furthermore, the results show that the market reaction to the bid announcement better predicts bidders long-term performance in the case of positive short-term abnormal returns.

<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.

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
