This study examines the impact of the COVID-19 outbreak on the Taiwan stock market and investigates whether companies with a commitment to corporate social responsibility (CSR) were less affected. This study uses a selection of companies provided by CommonWealth magazine to classify the listed companies in Taiwan as CSR and non-CSR companies. The event study approach is applied to examine the change in the stock prices of CSR companies after the first COVID-19 outbreak in Taiwan. The empirical results indicate that the stock prices of all companies generated significantly negative abnormal returns and negative cumulative abnormal returns after the outbreak. Compared with all companies and with non-CSR companies, CSR companies were less affected by the outbreak; their stock prices were relatively resistant to the fall and they recovered faster. In addition, the cumulative impact of the COVID-19 on the stock prices of CSR companies is smaller than that of non-CSR companies on both short- and long-term bases. However, the stock price performance of non-CSR companies was not weaker than that of CSR companies during times when the impact of the pandemic was lower or during the price recovery phase.

This paper expands the available information on the effects of delisting in Russia, and represents a rare empirical analysis of the impact of external events on securities prices in this major global market. We seek to evaluate how stock prices of competing companies fluctuate around the dates of stock market delisting announcements and completion. We analyse stock prices as correlated with company delisting events from 2004 to 2019 on 552 companies on the Russian MOEX Exchange. The event study methodology is used to evaluate the abnormal returns of rival companies close to relevant delisting dates. These data were checked for statistical significance using the standardised Patell residual test. The results indicate a significant competitive effect on stock prices both on the dates of delisting announcement and on completion, with more significant returns close to announcement dates. These effects were found to influence the prospects not just of individual groups of companies, but of all market participants. We may conclude from our results that delisting is not an event limited in effect to only one company, but impacts the industry as a whole, temporarily changing its value. As such, it will interest both shareholders and managers of public companies, and any participants of industries in which delisting occurs.

This study examines the impact of environmental regulation on the Singapore stock market using the event study methodology. Several asset pricing models are used to estimate sectoral abnormal returns. Additionally, we estimate the change in systematic risk after the introduction of the carbon tax and related regulation. We conduct various robustness tests, including the Corrado non-parametric ranking test, the Chesney non-parametric conditional distribution approach, a representation of market integration, and Fama–French five-factor model. We find evidence showing that the environmental regulations tend to achieve their desired effects in Singapore in which several big polluters (including industrial metals and mining, forestry and papers, and electrical equipment and services) were negatively affected by the announcements of environmental regulations and carbon tax. In addition, our results indicate that the electricity sector, one of the biggest polluters, was negatively affected by the announcement of environmental regulations and carbon tax. We also find that environmental regulations seem to boost the performance of environmentally-friendly sectors whereby we find the alternative energy industry (focusing on new renewable energy technologies) experienced a sizeable positive reaction following the announcements of these regulations.

<div><p><em>Immediately after World War II, many European nations felt it was important to unite the European nations to form a union for the economic and social benefits.  However, the dream of a “Common European Union” is still quite far from reality.  The EU is the England’s largest business partner.  Almost fifty percent of Britain’s trade is with the EU. Now, Britain’s decision to leave the EU is a death blow to the EU.  Today, the Brexit is viewed as the next big financial event since 2008 subprime crisis causing dent on the global economy.  History has exhibited that stock market plays a major role in any economy. Stock markets have been impacted by various macro and micro economic factors. Therefore, the main objective of this empirical paper is to investigate the pricing behaviour of the chosen benchmark indices (Sensex and Nifty) with respect to a major political event (Brexit referendum) and its implications for regulators, researchers and market participants.  For the purpose of the study the data has been collected from 24-06-2015 to 19-07-2016 and the collected data has been tested for stationarity by applying ADF test. The event study methodology has been employed to determine the impact of Brexit referendum on India stock market.  In order to capture the historical volatility the standard deviation of the abnormal returns of the selected indices has been computed.  GARCH (1,1) model have been employed to ascertain the existence of ARCH/GARCH effect in the indices. We found a significant impact of Brexit referendum on both the chosen indices on the event day.  Nobody knows the actual impact of the Brexit on the world economy in the long run. The bulk of studies on Brexit referendum have concluded that the impact on the Britain’s economy would be significant and adverse. However, the shock on the European Union would be smaller, although no extensive macroeconomic assessment has been published.</em></p></div>

A merger includes two relatively equal entities that are combined to form one legal entity worth more than a sum of its two separate parts. In the last few years, many Nepali financial institutions have been consolidating through mergers and acquisitions. This paper aims to investigate how the stock market reacts when financial institutions announce mergers and acquisitions. This paper also examines the impact of cross-sectional variables on the abnormal returns obtained around merger announcements. The study covers 22 successful merger deals that occurred among 48 financial institutions over the period of 2004 to 2013. This paper used the event study method based on the market model to derive abnormal returns associated around the merger announcement date. The event dates are specified as the dates on which the mergers and acquisitions were announced. The results show that leaving a very few exceptional cases, none of the merged financial institutions received significant cumulative abnormal returns on the merger announcements, regardless of the use of different event periods. The cross-sectional regressions show that the pre-merger performance of target and relative market value are the significant influencing variables on acquirers' cumulative abnormal returns. The finding implies that Nepali financial institutions merge merely to increase their capital base without producing any synergistic effect. Therefore, they need strategic plans for choosing the right partner and achieving other benefits like synergy effect, economies of scale and cost reduction from mergers and acquisitions.

Purpose – The purpose of this paper is to examine the informational efficiency and integration simultaneously for select Asian and US stock markets while considering the impact of recent financial crisis. Design/methodology/approach – Daily stock market data from 13 world markets covering the period of ten years (from January 1, 2000 to December 31, 2010) is tested using Run test, Unit root test, GARCH(1, 1) model, Pearson correlation coefficient, Johansen’s cointegration test and Granger causality test. Findings – It is concluded that the markets under study are inefficient in weak form which creates the chances of earning abnormal returns for the investors. Furthermore, the markets are found to be correlated and integrated in long-run, which makes the international fund diversification insignificant. The degree of inefficiency, in general, is not affected by the recent financial crisis but the level of integration among stock markets is reduced with the effect of recent financial crisis. Practical implications – Individual/institutional investors, portfolio managers, corporate executives, policy makers and practitioners may draw meaningful conclusions from the findings of this type of researches while operating in stock markets. They can use such studies for the management of their existing portfolios as their portfolio management strategies may be, up to some extent, dependent upon such research work. Originality/value – The originality of the present study lies in the fact that this paper is an attempt to fill the time gap of comprehensive researches on Asian and US markets and an effort to test stock market efficiency and integration simultaneously.

This event study analyses stock market reactions of 621 adhoc notifications announcing interorganizational cooperative agreements issued by stock listed German firms between 1999 and 2007. Besides testing the general relationship between ad hoc notifications of interorganizational cooperations and stock market response this study is the first one analyzing different institutional types of cooperational agreements for the German stock market. The announcement cooperational agreements results in significant positive mean abnormal returns. Surprisingly, announcements of contractual partnerships yield the highest abnormal returns compared to alternative forms combined with equity stakes. Obviously, shareholders do not necessarily relate better control of interorganizational cooperation to ownership.

In 2018, the China-U.S. trade dispute started, which brings heterogeneous impacts on the global economy. The purpose of this paper is to examine the effects of tariffs targeting Chinese exporting commodities imposed by the U.S. on the Chinese stock market by utilizing the event study analysis. 10 industries' stock returns between Jan. 3rd , 2017, and Apr. 3rd , 2020 were selected as the research objectives from the WIND database, according to the Chinese Shen Wan's classification standard. Results based on event study analysis show that: First, the China-U.S. trade dispute causes significant fluctuations to Chinese stock returns. Second, the impacts of the trade dispute are mainly negative, showing by the negative cumulative average abnormal returns in the export-oriented sectors when they are encountered with new tariffs imposed by the United States. However, the effects can also be positive because of the various situations of targeted industries, and the defensive measures taken by China. Third, the trade dispute also affects investors' views on the macro economy, in which the impact on the real economy can be transferred to other non-export-oriented industries, such as the banking sector. This study provides empirical evidence for China's policymakers to take measures in strengthening the independence of innovation, protecting intellectual property rights. Investors also need to equip themselves with more financial knowledge.

Empirical testing of the linkages between macroeconomic news and asset price movements in terms of response to released macroeconomic information have been a subject of many investigations using different testing methods. The objective of this paper is to study the impact of announcements of Greek credit rating downgrades on the prices of the most liquid assets quoted in the Czech stock market. This issue is tightly related to semi-strong form of the efficient market hypothesis, which is one of possible analytical approaches when analyzing behaviour of assets in financial markets. The reaction of the Czech stock market is assessed in relation to seven announcements of Moody´s rating agency regarding changes of credit rating of Greek government bonds in the period 2009–2012. For the purpose of this paper, the event study methodology is applied. The basic idea of this statistical method is to determine values of abnormal returns, which can be defined as a difference between actual and equilibrium returns. In order to calculate equilibrium returns, the Capital Asset Pricing Model (CAPM) is used. The differences between actual and equilibrium returns are then verified with a help of selected nonparametric statistical tests. Namely, the exact sign test and the Wilcoxon signed-rank test are utilized. Based on results of nonparametric statistical tests, the null hypothesis of information efficiency of the Czech stock market is conclusively rejected.
