This research investigated the performance of a dynamic portfolio that consists of sustainable/ethical stocks and gold. The main purpose of this study is to prove that the inclusion of gold in sustainable/ethical stocks portfolios could produce better performance. Therefore, the method used in this research, DCC-GARCH, was relaxing the basic assumptions in the theory of modern portfolio that is under the assumption of the normality of stock return and securities would have constant correlation. This research used data such as SRI-KEHATI Index (SKI) and Jakarta Islamic Index (JII) in Indonesia as a proxy for sustainable investments. Additionally, this research used gold from 2013 to 2019. This study is able to provide evidence regarding the ability of a dynamic portfolio to minimize the level of portfolio risk. However, this led a lower rate of return. Based on the OLS regression, gold is also proven as a weak safe haven for sustainable investment in Indonesia. Investors who believe in ethical investment may include gold in this time-varying approach when formulating the portfolio to reduce risk significantly. The inclusion of gold in portfolios could produce hedging effectiveness. Overall, this study supports some previous findings regarding the ability of gold as an instrument, which could reduce investment risk if involved in a portfolio.

This study, which was prompted by the COVID-19 crisis, aims to assess the dividend policies of manufacturing firms, and examine market reactions to these corporate actions. A comprehensive evaluation of robustness was carried out, encompassing sub-period and sub-sample robustness checks, along with consistency testing for various key variable proxies. The effects of dividend announcements on the stock market were investigated across three time periods: 2019 to 2021. The main models indicate a positive dividend policy of manufacturing firms during the pandemic, revealing that the firms maintained or enhanced dividends amidst the pandemic, which was consistent in all sub-period check estimations. Conversely, distinct findings are observed within the Basic and Chemical industry sectors, while the Consumer Goods and Miscellaneous industries align with this study's results. The study also demonstrates the relevance of the findings to dividend signaling theory but not to the pecking order theory. Furthermore, the market reactions to dividend announcements during the 2020 crisis were strong and positive, in contrast to the weaker sensitivity observed in 2019 and 2021. This study bears significant implications for the crisis-time dividend policies for firms, implying that corporations should exhibit heightened responsiveness during such periods to transmit a positive signal to the market amid sluggish stock market activity.

Nowadays, the ESG-oriented portfolios are very popular. This study aims to study the performance of cross-asset portfolios between eco-friendly stocks (represented by Sri-Kehati index) with cryptocurrencies, bonds and gold. The data used in the study were the daily return of each instrument from January 2019 to December 2021, which was then analyzed using the DCC-GARCH analysis technique. The results show that adding Ripple, gold and bonds into a portfolio consisting of Sri-Kehati stocks can reduce the investment risk. The findings imply that investment managers and investors who have portfolios consisting of eco-friendly stocks such as Sri-Kehati stocks and bonds may reduce investment risk and balance their portfolios by adding gold or cryptocurrencies separately.

Capital market integration has become an interesting research topic nowadays. Many studies have tried to explain this phenomenon using various methods. Here, we used sophisticated methods to explain capital market integration. This study aims to scrutinize the Association of Southeast Asian Nations (ASEAN) capital market integration. This study hopefully can enrich the different views regarding the capital market integration and fill the gap left by previous studies. The data used were the stock price index of the monthly closing data of the capital markets in ASEAN countries during the period of January 1999 to December 2020, obtained from Bloomberg and the Indonesia Stock Exchange. Data in this study were analyzed using the wavelet method. The results indicate that there is a long-term integration in the capital markets of ASEAN countries, and the highest level of integration was in the period during and about a year after the global crisis. Using the spectrum analysis, the results show that during period from 2008 to 2010, the level of integration reached its highest level.

This study aims to analyze the effect of hedging for the risks of foreign currency, interest rate, and commodity price on firm value as measured by Tobin’s Q. The findings reveal that hedging with derivative instruments is insignificantly related to firm value but significantly varied in financial risks. Hedging for foreign currency risk has a significantly positive relation to firm value, while hedging for interest rate and commodity price risk has no relation. Furthermore, this study provides a novelty compared to previous studies in the utilization of the extent of hedging as the variable to measure the implementation of hedging.
