Abstract

The aim of this research is to investigate the impact of investor sentiment on value and stocks return. Two investor sentiment indicators, volatility index VIX and sentiment index are used as independent variables. Technical proxies (relative strength index, psychological line index, trading volumes and adjusted turnover rate) are used to construct sentiment index using principal component analysis. The dependent variable is value and growth stocks return formed based on the book to market ratio. Three Fama-French factors are used as control variables to isolate the impact of investor sentiment from systematic risk and fundamental factors. We use companies listed on Kompas 100 index over the sample period February 2017-January 2023. The sampling technique was carried out by purposive sampling and obtained 45 companies as the research samples. The empirical analysis employs multiple regression analysis using 1.385 daily time series computed by Microsoft Excel and Stata 13. The regression results indicate that volatility index VIX has a negative significant effect on value and growth stocks return. Sentiment index has a positive and significant effect on value stocks return but does not have a significant effect on growth stocks return. Investor sentiment has a greater effect on value stocks than growth stocks.

Abstract

This research aims to analyze the relationship between Corporate Social and Governance pillars and green innovation in the Southeast Asian energy sector. It is a quantitative study that relies on secondary data from Refinitiv Eikon and relevant websites, analyzed using panel data regression with STATA 14 software. The research focuses on public companies in the Southeast Asian energy sector, using purposive sampling based on specific criteria, including operating between 2020-2023, having complete ESG data, and issuing financial statements during this period. This research provides a structured approach to understanding the impact of corporate social pillar includes workforce, human rights, community, and product responsibility, while the governance pillar comprises management, shareholders, and CSR strategies on green innovation in the Southeast Asian energy sector. The results of the study indicate a significant relationship between company performance and green innovation in the ASEAN energy sector. Analysis of sustainable performance variables, based on the ESG categories from the Refinitiv Eikon Database, reveals that social and governance-related scores influence green innovation in companies. Specifically, the workforce score, human rights score, and product responsibility score have a positive and significant relationship with the company’s green innovation, while the community score shows a negative and significant relationship. In terms of governance, the management score has a negative and significant relationship with green innovation, whereas the shareholder score is positively and significantly related to green innovation. The CSR strategy score, although positive, does not have a significant relationship with green innovation in the ASEAN energy sector. This study highlights the importance of social and governance factors in driving green innovation and the need to pay close attention to specific elements that can support the successful implementation of green innovation in this sector.
