This article analyzes the effects of rumor and official rumor clarification on Chinese stock returns under different rumor conditions using an event study. The results are based on a sample of 832 rumor clarification announcements from China Listed Companies spanning the period of 2015 to 2017. The results show that the average cumulative abnormal return after the rumor event is significantly positive in the positive rumor sample and neutral sample, and significantly negative in the negative rumor sample. After the clarification announcements, we find the announcements effective for the positive and neutral rumor sample, but not in the case of the negative sample. However, by comparing different clarification times of each sample, we find that the earlier the clarification time is, the smaller the impact on the companies in positive and negative rumor examples.

This study was carried out to examine the economic consequences ofvoluntary environmental reporting on shareholders' wealth among Malaysian Listed Companies that voluntarily disclosed environmental information in their financial report. One hundred andfifty two (152) companies of Bursa Malaysia (MSE) had been identified as a sample in the current study. Seventy six (76) companies were classified as environmental reporting companies while the remaining companies were classified as non-environmental reporting companies. The classification was done in order to determine the differences between share price, profitability and market equity for both types of companies. The study hypothesizes that voluntary environmental reporting leads to an improvement in the shareholders wealth. However, the results show that there is no significant difference between cumulative abnormal return for environmental and non-environmental reporting companies. Based on the results obtained, it can also be concluded that profitability and size of the companies do not have any significant roles in deciding whether or not to produce environmental reporting companies.

The outbreak of the COVID-19 epidemic has had an adverse effect on China's economy. This paper uses the event study method to test and measure the impact of the open market reverse repo (OMRR) operation on the Chinese stock market. The results show that the OMRR operation generates a positive daily abnormal return and a positive daily cumulative abnormal return on average for all stocks. The impact is larger for non-state-owned enterprise (non-SOE) firms than for SOE firms, stocks of non-Hubei provinces than those of the Hubei province, and for stocks of the information transmission and technology industry than those of other industries. We suggest that our government implement more prudent monetary policies and more proactive fiscal policies.

This study explicitly rejects the prima facie proposition that the top-tier investment banks are capable of delivering supernormal value creation to the shareholders of a REIT acquirer in a corporate acquisition. Using the event study method, we find that REIT acquirers advised by market-leading investment banks suffer an average cumulative abnormal return of −4.41% following the M&A announcement, whereas REIT acquirers advised by non-top-tier investment banks only suffer an average cumulative abnormal return of −1.49%. The evidence shows that the contemporary practice of employing investment banks based on the prestige of the advisory firms could potentially result in value-destroying M&As for the REIT acquirers.

We utilize data on comedy moviegoers from 18 cities in China to investigate the impact of the positive mood triggered by these movies on the stock returns of locally headquartered listed companies. We find that although these movies have no relation to investment itself, the sentiment triggered by these movies could affect the risk decision making of investors. Moreover, the stock returns of locally headquartered companies become significantly negative after comedy movies are screened in their respective cities. These results support the mood maintenance hypothesis. This research also provides new evidence for the presence of home bias in capital markets.JEL Classification: G11; G12

Although there is a plethora of studies which examine the impact of the COVID-19 pandemic on India’s financial sector, we contribute by investigating the effect of the ongoing COVID-19 pandemic on stock returns of Indian pharmaceutical companies. By employing an event study methodology, our results indicate that the average returns of the pharmaceutical sector are positive during the COVID-19 phase although mixed evidence is found at the firm level. This finding is also robust to alternative model specifications.

This study employs event study methodology to show that there were few days in which the average abnormal return (AAR) and cumulative average abnormal return (CAAR) are statistically significant. In addition, this study also further investigates the abnormal return (AR) and cumulative abnormal return (CAR) for individual companies. It was found that majority of the stocks returns fell significantly 30 days after the UMA announcement. The magnitude of the fall in returns ranges from 4% to 234%. Hence, it is not advisable for investors to buy stock after UMA announcement.
