In an era of challenging business and increasingly fierce competition, the company (business) reputation has become an increasingly valuable and vital asset. To maintain a good reputation, this study aims to explain what internal factors affect the business reputation and test the consistency of agency theory as a solution in explaining the influence of internal factors such as sustainability, millennial director, financial distress, board of commissioners, and company size on business reputation. The research used the power of panel data analysis, complemented by advanced statistical techniques such as Robust, Fixed Effects, Ordinary Least Square Regression, and Random Effects. This method is executed using Stata software, which offers incredible flexibility to seamlessly connect theoretical concepts and empirical data related to research variables. Results of this research show that sustainability and a board of commissioners are not able to have a significant influence on the business reputation; millennial directors and financial distress have a negative influence on the business reputation, while the company size has a significant positive effect on the business reputation. This research makes a valuable contribution to the company's management in considering important factors that can affect the business reputation, as well as taking appropriate steps to maintain and improve its reputation amid increasingly fierce business competition.

This study aims to estimate and predict the effect of stock prices on profit volatility, net profit, and comprehensive income on the Indonesia Stock Exchange for the period 2014-2019. The study uses quantitative analysis with secondary data consisting of 98 banking companies on the Indonesia stock exchange from 2014 to 2019. The results prove that the share price has a significant effect on net income and comprehensive income but does not have a significant effect on profit volatility, so that net and comprehensive income has relevance to the share price and investors can make both variables in conducting further fundamental research. Previous studies measured the level of volatility of earnings, net income, and comprehensive income on the share price, but when trialing other approaches by causality, share prices affect net income and comprehensive income but not for profit volatility. In this study, however, the change includes detailed income variables due to Financial Accounting Standard No. 1, a shift in terms from profit and loss statements to systematic profit and loss statements.
