Abstract

People may suffer from overconfidence in their daily activities. According to psychological research, less informed individuals may suffer from overconfidence. Empirical research shows that investors suffer from transaction losses due to overconfidence. This current research is an experimental research project that addresses these issues. According to the research design, all investors are classified into three groups based on their scores of overconfidence, namely the less informed investors, the rational (average) investors, and the more informed investors. In order to observe the responses of the groups of investors when they receive valuable information, the research employs four different types of treatments consisting of the condition of no market information, the provision of guidance of security prediction, the good news and the bad news. The research demonstrates that the less informed investors are inclined to assess the precision of their knowledge and information excessively so that they produce a higher mean of prediction and price errors than those of the more informed investors in all experimental market sessions, except in the market session of good news. The phenomenon indicates that less informed investors conduct a self deceptive behavior. The result of the research also shows that although the less informed investors have higher mean of prediction or price errors, they have a chance to gain profit as long as they are able to deliver the predicted value of the security accurately which is closer to the market price that reflects the expected price of the majority of the market players.

Abstract

Nilai perusahaan menjadi perspektif investor untuk mempertimbangkan keberhasilan perusahaan yang berkaitan dengan harga sahamnya. Industri barang konsumsi merupakan salah satu sektor investasi yang paling aman selama masa resesi karena kinerja emiten di industri ini cenderung ditopang oleh permintaan dalam negeri. Penelitian ini bertujuan untuk menguji pengaruh profitabilitas, kebijakan dividen dan investment opportunity set terhadap nilai perusahaan di sektor industri barang konsumsi yang terdaftar di BEI periode 2005-2021. Pengujian dilakukan dengan menggunakan analisis statistik deskriptif, uji normalitas data, dan uji hipotesis. Hasil penelitian menunjukkan bahwa profitabilitas (ROE), kebijakan dividen (DPR) dan investment opportunity set (MBVE) berpengaruh positif namun tidak signifikan terhadap nilai perusahaan di sektor industri barang konsumsi yang terdaftar di BEI periode 2005-2021.

Abstract

A family company or family business is a business in which two or more family members are directly involved to have ownership and become the main control of the business. The study examined the effect of family management, family ownership structure, capital structure and investment opportunity set on company performance. The population of this study is manufacturing companies listed on the Indonesia Stock Exchange from 2017 to 2022 and a sample of 22 companies using purposive sampling techniques. By using multiple linear regression for panel data and using data processing software in the form of Eviews, this study found that family management and family ownership structure did not affect company performance, capital structure had a negative and significant effect on company performance and investment opportunity set had a positive and significant effect on company performance.
