Abstract

Purpose: Investors continuously achieve abnormal returns (ARs) by adopting advanced strategies. Therefore, this study aimed to compare the performance of the IDX Value30 and IDX Growth30 indices, which represent value and growth investment strategies in Indonesia. Method: The comparison in this study was conducted using return- and risk-adjusted variables represented by Information Ratios and Jensen’s alpha. Based on this approach, Mann-Whitney and independent sample t-tests were performed using the SPSS program. Results: Both the IDX Value30 and IDX Growth30 indices show positive abnormal returns. However, a comparison of returns, Information Ratios, and Jensen's alpha showed no significant differences between the IDX Value30 and IDX Growth30. Limitations: The secondary data of IDX Value30 and IDX Growth30 indices were limited to the period from January 30, 2014, to September 30, 2022.   Contribution: IDX Value30 and IDX Growth30 could serve as references for investors and Investment Managers in executing value- and growth-investing strategies to outperform IHSG. Furthermore, Investment Managers could use these indices as benchmarks for issuing index funds or ETFs. Novelty: This study uniquely compares the performance of value and growth investing using the IDX Value30 and IDX Growth30 indices, a comparison that has not been previously conducted.

Abstract

Value and growth investing strategies are often compared in the investment world. This study analyzes the differences in performance of the IDX Value30 and IDX Growth30 indices as a representation of these strategies in Indonesia during the period from January 30, 2014, to September 30, 2022. Measurements were made using the Treynor Ratio, Information Ratio, and stock selection and market timing evaluations through the GARCH (1,1) model. In addition, the APT model was also used to test the influence of macroeconomic factors, such as inflation, IDR/USD exchange rate, and 5-year Government Bond Yield. The comparison of Treynor and Information Ratio was tested using the Mann-Whitney and independent sample t-test. The results show that both indices have positive performance ratios but are not significantly different. Both do not show stock selection capabilities, but IDX Value30 has market timing capabilities. The IDR/USD exchange rate has a negative effect, and the 5-year Government Bond Yield has a positive effect on IDX Value30, while there are no significant macroeconomic factors on IDX Growth30. This research provides a new contribution through a comprehensive analysis of IDX Value30 and IDX Growth30, which can be used as a reference for investment strategies in the Indonesian capital market.
