Abstract

This study aims to examine whether asset allocation strategies to the innovation sector can provide superior portfolio performance to investors. This type of research is comparative research using secondary data sources. The sample used is ETFs (Exchange Traded Funds) from investment companies namely BlackRock and Ark Invest since 2015. The focus of this study is to compare the performance of portfolios without an allocation to innovation assets and portfolios with allocations to innovation assets. This study analyzes the difference in performance between the two portfolios for various weightings and several portfolio optimization approaches, such as 'equal weighting' (1/N), optimality Lagrange, minimum-variance (MinVar), mean-variance (MV), and market-value weighted strategy.

Abstract

This research aims to determine the effect of earnings management on the financial performance of Initial Public Offering companies listed on the Indonesia Stock Exchange in 2010 - 2018. This research also uses two control variables: firm size and sales growth. The sample used is non-financial companies that report complete financial reports. The method used for this research is Ordinary Least Square regression with the Pooled Least Square data type. The results of this research indicate that earnings management has a significant negative effect on the company's financial performance. The regression results also explain that firm size has a significant positive result, which means that the impact of earnings management on the company's financial performance also depends on the size of the company. However, the control variable sales growth does not have significant results, so the impact of earnings management on the company's financial performance does not depend on the company's sales growth.

Abstract

Research Aims: This study aims to analyse the influence of top management's commitment on competitive advantage through supply chain digitalisation, responsiveness, and resiliency. Design/Methodology/Approach: Data were collected using a five-point Likert-scale questionnaire distributed to manufacturing practitioners with a minimum supervisory position. A total of 203 valid questionnaires were analysed. Data processing was performed using SmartPLS version 4.0 to test measurement and structural models. Research Findings: The study results indicate that eight hypotheses are accepted and one is rejected. Top management commitment positively impacts supply chain digitalisation, responsiveness, and resilience. Furthermore, supply chain digitalisation and supply chain resilience both positively impact competitive advantage. However, supply chain responsiveness did not affect competitive advantage. Theoretical Contribution/Originality: This research makes a theoretical contribution to the study of digital technology adoption in supply chain management. Digital technology adoption enhances companies' competitive advantage. Managerial Implications in the South East Asian Context: In Southeast Asia, there is still low integration, limited digitalisation, and vulnerability to supply chain disruption. The results of this study provide insight into the role of top management in initiating the adoption of digital technology to strengthen resilience and supply chain responsiveness, thereby improving competitive advantage. Research Limitation and Implications: This study has limitations, particularly on the research sample, which is located in East Java, Indonesia. Hence, the study results may not be valid in other countries.
