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.

The study was conducted to examine the influence of several factors that are suspected to affect the health care sector's stock returns, moderated by the capital structure proxied by the debt to equity ratio (DER). The population used in this research were seventeen companies, and the samples that match the research criteria were seven health care companies listed on the Indonesian stock exchange between 2018-2022. The research used panel data analysis techniques, and utilizes financial reports. The results of this study y indicate that profitability proxied by the return on equity (ROE) and institutional ownership has a positive influence, and DER has a negative influence on the stock return, while the firm size do not has significant effect on the stock return. The ROE and firm size are moderated by capital structure in their influence on the stock return. The findings of this study suggest that in maximizing the stock return in the health care sector's, companies need to increase profits, have a high level of institutional ownership and maximize sources of funds for the operational activities, as well as optimizing the use of debt to invest in assets.

The goal of this study was to examine LQ45 businesses' dividend policies on the Indonesia Stock Exchange by dissecting their dividend policy drivers and controlling variables using excellent corporate governance as a moderator. Participants in the research were companies that were included in the LQ45 index for the years 2019 and 2023. As part of a causal research strategy, hypothesis testing was used. The sample was determined using a purposeful sampling technique, which resulted in 25 sample businesses. In order to analyze the data, panel data regression was used. This statistical program was constructed using Eviews version 13.0. Results showed that dividend policy is affected by profitability, interest rates, and excellent corporate governance in a favorable way, and by leverage and free cash flow in a negative one. There was also no correlation between company size and dividend policy. One interesting finding is that effective corporate governance acts as a moderator, enhancing the influence of free cash flow on dividend policy while reducing the impacts of profitability, debt, and firm size. Good corporate governance did nothing to reduce the correlation between dividend policy and interest rates.

The Indonesian capital market plays a crucial role in economic growth, with the LQ45 index representing large-cap stocks with high liquidity. This study aims to evaluate the effectiveness of the Moving Average Convergence Divergence (MACD) and Bollinger Bands technical indicators in making investment decisions on stocks during the period from January 2023 to February 2025. The research method used is descriptive qualitative, with visual analysis of price movements from 11 LQ45 stocks. The findings indicate that the combination of MACD and Bollinger Bands produces fairly accurate buy and sell signals, especially when used simultaneously. These findings provide a solid foundation for investors to formulate practical and applicable strategies based on technical analysis. Furthermore, this study contributes to the literature on the reliability of technical signals in the Indonesian stock market.

The data for this study is 25 corporate bonds as a sample from a total population of 59 corporate bonds. The research sample was tested using panel data analysis techniques, namely descriptive and inferential statistics. The test results show that profitability with the Yield of Assets indicator and company size has a positive effect, liquidity with the Current Ratio indicator has a negative effect and bond ratings do not affect the yield to maturity of corporate bonds in Indonesia. Furthermore, it was found that there is a role of leverage as a moderating variable, namely, leverage weakens the effect of ROA and bond ratings on the yield to maturity of corporate bonds and strengthens the effect of the Current Ratio on the yield to maturity of corporate bonds.

The objective of this study is to examine the influence of macroeconomic variables specifically exchange rates, interest rates, and inflation on stock returns, both directly and indirectly through beta, within the food and beverage sector. Additionally, it explores the impact of the COVID-19 pandemic. This research adopts a quantitative approach, targeting companies listed on the Indonesia Stock Exchange within the food and beverage industry. Secondary data, sourced through library research, underpins the study, which employs panel data analysis as a primary method. The findings indicate that inflation does not negatively affect stock returns, similar to interest rates and exchange rates, which also show no adverse impact. Furthermore, the COVID-19 pandemic was found to have no positive influence on stock returns in this sector. Regarding systematic risk, beta appears to diminish the effect of inflation, interest rates, and exchange rates on stock returns, while it does not amplify the impact of the COVID-19 pandemic. These results carry significant implications for managers and investors, suggesting that external macroeconomic conditions and beta are not the key determinants of stock returns.
