The Covid-19 pandemic has deeply affected our health and social life as well as the financial markets. Although the global economic effects of the coronavirus are not yet clear, it is observed that there is a reaction in the financial markets to the developments related to the pandemic. Studies show that the pandemic has strong impact on stock markets and increases uncertainty. The purpose of this study is to examine whether the stock prices of companies traded on the Istanbul Stock Exchange Market between 02.14.2019 and 04.01.2020 are affected by the Covid-19 pandemic. In this context, the stock prices of the six major sectors traded and thought to be affected in Istanbul Stock Exchange Market during the period examined were analyzed using the "event study" method of the effects of Corona virus. In the analysis, the event window was taken as (- 15, + 15) trading days. The effects of the Corona virus in the relevant period were examined separately for each company in the selected sectors, and after calculating the abnormal returns, the effect on the average abnormal returns and cumulative abnormal returns were analyzed. According to the research results; when the general picture of selected sectors in Covid-19 is examined, statistically significant negative average cumulative abnormal returns are obtained.

This study attempts to investigate the stock price reaction to divi-dend announcements using data of Vietnamese listed firms on Hochiminh Stock Exchange (HOSE). Standard event study meth-odology has been employed on a sample of 198 cash dividend an-nouncements made in 2011. The results show that stock prices react significantly and positively to the announcements of cash dividends, including both dividend increasing and dividend decreasing events. It is also plausible that cumulative abnormal returns exhibit an in-creasing trend before announcement yet a decreasing trend after announcement dates. More specifically, we find positively signifi-cant cumulative abnormal returns of around 1.03% on announce-ment dates; other larger windows also demonstrate positive abnor-mal returns of around 1.3%. In addition, cash dividends have differ-ent effects on share prices of firms from different industries. These results support the signaling hypothesis and are also consistent with prior findings of empirical research done on more developed mar-kets, i.e. the US and the UK.

This research is an event study that aims to determine the market reaction arising from the 2019 Indonesian presidential election, against companies listed in the infrastructure stock sector on April 17, 2019, using the abnormal return indicator.

The statistical tests used to test hypotheses are descriptive statistical tests, normality tests and one sample t-test. The results of the one sample t-test on abnormal return is that there is no significant difference, which means the market does not respond to the event. These results indicate that the efficient market is not answered in the 2019 Indonesian presidential election due to the absence of abnormal returns in it.

The Impact

Stock markets are the barometers of an economy. They are very sensitive to the news and can measure economic pressures to forecast economy. They react momentarily to crises that might be triggered by such events as a currency crisis, a debt crisis, a political crisis, or an accounting fraud crisis. According to technical analysts, drastic decreases in stock prices recover from their crash value rapidly since these decreases are realized with low traded values. The overreaction hypothesis affirms that extreme price movements are subsequently adjusted by opposite direction. This chapter analyses these assertions by measuring the impacts of the crises on the Istanbul Stock Exchange (ISE) over the last decade. The duration of the crises and weekly negative abnormal percentage returns in the period of 01.01.2000-31.12.2011 are analyzed using a regression model. In this period, from a total of 621 weeks, 277 weeks have negative returns, 93 of which are identified as negative abnormal returns. The results are statistically significant, and suggest that the duration of the crises is related to the magnitude of negative returns. On the other hand, research shows that the duration of the crisis and traded value are positively correlated. This study offers empirical observations that would be useful for technical analysts and stock investors.

Tsunami Earthquake

Natural disaster often brings damage to the economy, including the decrease of stock’s market value. For this reason, this study aims to determine the effect of the tsunami earthquakes in Lombok in 2018 on abnormal returns and cumulative abnormal returns of insurance companies. This study used the event study approach, with three days window period after the three tsunami earthquakes from July to August 2018. The sample of this study is the stock price of 14 insurance companies listed on the Indonesia Stock Exchange. To test whether abnormal return exists, a one-sample t-test was used on the average abnormal and cumulative returns. The results show that the tsunami earthquake disasters in Lombok in 2018 have a significant effect on cumulative abnormal returns of insurance companies stocks, and this effect even bigger on the third tsunami. This finding shows that the market reacts to continuous disaster by considering the earthquake as negative information and thus decrease the stock price. This study implies that investors may buy the stocks after the disaster to get a cheaper price or hold the stocks to avoid loss.

Event Study Methodology

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.

Information Spread

This research study empirically assessed the corona virus information spread and banks’ stock returns in Nigeria. The study adopted event study approach which suites the research because of its descriptive nature. The daily data of closing share prices of the selected banks listed in Nigerian Stock Exchange (NSE) was collected from NSE website for a period of 146 days. Using 124 days estimation window, the result shows that the Intercept (C) and Market Returns (MKTR) has a coefficient of -0.00125 and -0.00848 respectively. Analyzing the stock of commercial banks in the Nigerian stock exchange during the first 100 days of COVID-19 contagious infectious disease outbreak in Nigeria, we find that the pandemic disease interacts positively with stock returns which is against the expectation. Specifically, banking firms’ abnormal returns on the corona virus information spread at 100th day are positive but insignificant. We therefore conclude that COVID-19 information into the Nigerian banking sector triggers positive investment in the sector with desirable abnormal returns. We therefore call the relevant authorities to adequately consider policy responses implemented in the sector, and to further analyze information about the COVID-19.
