<![CDATA[The objective of this study is to analyze the reaction of Southeast Asian capital markets to the second wave of the Covid-19 pandemic, in this case the Delta Variant. This study uses a quantitative research approach with descriptive analysis and comparative methods. The population in this study is the capital markets of Southeast Asian countries. Furthermore, the sampling technique is non-probability sampling, samples that meet the criteria are the capital markets of Indonesia, Malaysia, Singapore and Thailand. The results showed that based on the one sample T-test, there were abnormal returns in all Southeast Asian countries sampled for the second wave of Covid-19. However, the results show a different response from each country. The countries of Indonesia, Malaysia and Singapore show that investors in the capital markets of these countries can still benefit from positive abnormal returns on investments made as long as they make careful and mature decisions. The positive response at the start of the Delta variant's appearance could be due to investor confidence regarding the government's Covid-19 disaster mitigation. Meanwhile in Thailand, after the event date showed a negative response to the second wave of Covid-19. In addition, the presence of abnormal returns indicates that the market is efficient in the semi-strong form in terms of information in all the countries studied.]]>

The population in this study are members of the LQ-45 stock index which are listed on the Indonesia Stock Exchange. The statistical test is used to study the one sample t-tes and paired sample t-test. The one sample t-test result shows that there is a negative abnormal return in the 6 days surrounding the event, which means that the market responds to the event of the DPR-RI inauguration.

<![CDATA[This study analyzes the effect of liquidity, capital structure, and profitability on dividend policy with company size as a moderating variable in consumer goods industry sector companies listed on the Indonesia Stock Exchange (IDX) for the period 2019–2023. This study uses a quantitative approach with descriptive and associative methods. Data were obtained from the company's financial and annual reports, analyzed using Microsoft Excel and EViews. The sample consisted of 19 companies selected through the Non-Probability Sampling technique, with a total of 95 observations. The results of the analysis show that the classical assumption test has been met, including data normality, free from heteroscedasticity, multicollinearity, and autocorrelation. Partially, liquidity and capital structure have no effect on dividend policy, while profitability has a positive effect. Company size is unable to moderate the relationship between independent variables and dividend policy. These findings indicate that financial factors remain dominant in determining dividend policy, but future research is advised to consider non-financial factors and a longer period to obtain more accurate results.]]>
