Investment Strategy, Manager Characteristics, and Corporate Governance Effects on Mutual Fund Performance: A Study of PT Asuransi Jiwasraya (Persero) During Period of 2013-2018

This study aims to examine the relationships between investment strategies, investment manager characteristics, and corporate governance on the investment performance of PT Asuransi Jiwasraya (Persero)’s mutual funds investment from 2013 to 2018. The year 2013 marked the introduction of a new bancassurance product, which necessitated PT AJS to generate higher returns on investment in a short-term period. The sudden change in management in 2018 brought the mismanagement case to public attention. The analysis utilized a cross-sectional multilinear regression approach, allowing for the examination of multiple independent variables and their relationship with the dependent variable. Data for the study is collected from various sources, including annual reports, financial reports, prospectuses, and court documents. The relationships are assessed using seven regression models, with measures such as mean return, standard deviation, beta, Sharpe ratio, Treynor ratio, Jensen’s Alpha, and state loss as the dependent variables. The regression models are estimated using SPSS software, and assumptions of linearity, independence of errors, homoscedasticity, and absence of multicollinearity are checked to ensure the validity of the analysis. Hypothesis testing is conducted to determine the statistical significance of the relationships, and measures such as R-squared, adjusted R-squared, and F-statistic are used to assess the overall goodness-of-fit of the models. The findings indicate that the models for mean return, Treynor ratio, Jensen’s Alpha, and state loss are statistically significant, demonstrating a strong correlation and high explanatory power. The results suggest that value investing and smaller market capitalization of constituent stocks have a positive association with investment performance. Additionally, reducing the presence of dividend-paying and suspect stocks is beneficial for investment performance. Factors such as management fees, education background, and years of experience show significant positive relationships, while investment horizon, asset size, and past performance have significant negative relationships with investment performance. The age of the investment manager does not exhibit a significant relationship. Furthermore, corporate governance demonstrates a negative relationship with investment performance. These findings provide valuable insights for improving investment performance and offer important lessons to prevent similar cases of mismanagement of investment funds in the future.
