Abstract

This study sought to determine the outcomes of corporate bankruptcy predictions using the Springate, Zmijewski, and Grover models on companies impacted by the Israeli Boycott, Divestment, Sanctions (BDS) Movement. The study's population consisted of 22 companies affected by the Israeli BDS Movement operating within Indonesia. A total sampling technique was employed, including all 22 companies. The analysis utilized three distinct models Springate, Zmijewski, and Grover to predict corporate bankruptcy. The analysis of bankruptcy predictions yielded the following results: the Springate model predicted 12 companies would experience bankruptcy, with 10 not at risk. The Zmijewski model identified 6 companies as potentially bankrupt and 16 as not at risk. The Grover model predicted 5 companies would experience bankruptcy and 17 would not. Overall, the combined analysis of the three models identified 3 companies that were predicted to experience bankruptcy and 8 companies that were not.

Abstract

This study examines the influence of cognitive dissonance bias, overconfidence bias, and herding bias on investment decisions in stocks listed on the Indonesia Stock Exchange. The study employs a questionnaire method as a data collection technique, involving a sample of 150 respondents, all of whom are residents of West Kalimantan who invest in stocks on the Indonesia Stock Exchange. The data analysis techniques used include multiple linear regression analysis, multiple correlation coefficient (R), coefficient of determination (R²), simultaneous test (F-test), and partial test (t-test). The results of the study indicate that cognitive dissonance bias, overconfidence bias, and herding bias have a positive and significant influence on investment decisions. This suggests that these three types of behavioral biases play an important role in the individual investment decision-making process. In other words, when investors experience a mismatch between their beliefs and new information, exhibit excessive self-confidence, or tend to follow the decisions of the majority, they are more likely to make investment decisions without thoroughly considering rational analysis. These findings highlight the importance of understanding investor psychology and financial literacy in minimizing the impact of cognitive biases. Proper education and enhanced awareness of financial behavior are expected to help investors make more objective and rational decisions, thereby reducing potential losses and improving the quality of investment decisions in the capital market.

Abstract

This study investigates the influence of familiarity bias and attention grabbing on abnormal returns during black swan events. The analysis employs the traditional Capital Asset Pricing Model, expanded with prospect theory and the Fama and French Three- Factor Model, incorporating psychological variables such as familiarity and attention grabbing. The population comprises all companies listed and actively traded on the Indonesia Stock Exchange from 1997 to 2020. A systematic sampling method was used to determine the sample, resulting in 5,615 observations based on trading days over 23 years across nine sectors. The findings reveal that familiarity bias does not uniformly occur across all sectors during black swan events. Sectors significantly affected, either positively or negatively, include agriculture, consumer goods, finance, mining, property and construction, and trade and services. Moderation analysis shows a negative relationship between attention grabbing and abnormal returns, which weakens during black swan events. This suggests that the negative impact of attention grabbing on abnormal returns diminishes under extreme market conditions. The study highlights the behavioral dynamics of capital markets during rare and unpredictable events, emphasizing the relevance of behavioral finance. It also supports the notion of increasing integration among global financial markets, as evidenced by similar reactions in international capital markets. This research is limited to representative biases, specifically familiarity and attention grabbing. Other psychological biases beyond representativeness remain unexplored and warrant further study, particularly during crisis periods. Additionally, the use of secondary data suggests future research could benefit from primary data collection for deeper behavioral insights.

Abstract

This study aims to analyze the influence of gold prices, income, and financial management on the decision to invest in gold savings among employees of PT Bank Syariah Indonesia, Tbk in Pontianak and Kubu Raya, with investor knowledge serving as a moderating variable. An associative research design was employed, with data collected from 151 employees using a saturated sampling technique. The data were analyzed using multiple linear regression and moderated regression analysis (MRA). The results of the study indicate that gold prices have a significant effect on investment decisions, whereas income and financial management do not have a significant impact. Investor knowledge was found to moderate the relationship between gold price fluctuations and investment decisions. These findings highlight the importance of understanding gold price movements and effective financial management when making investment decisions. The study is expected to contribute to the enhancement of financial literacy among employees
