The study aims to investigate a prevalent and essential kind of data collection for corporate investors: site visits, which refer to visits made to the firms' production facilities and corporate headquarters. The study examined the impact of investors' site visits on the correlation of stock market prices and the effectiveness of profitability. The study has involved the analysis of data collected from the Kuala Lumpur Stock Exchange from 2005 to 2023. The methodology has used Potential Mechanisms tests, Endogeneity treatment tests, Synch index validity tests, and Robustness tests to analyze the research data. The results revealed that the investors' site visits have been found to reduce synchronization among stock market prices and improve profitability efficiency. The investors' site visits also have a stronger impact on organizations that have lower-quality information disclosure and weaker corporate management. The study presents the beneficial effects of investor site visits on enterprises, particularly highlighting their influence on market pricing efficiency.
