초록

Purpose - This study was a study on managerial overconfidence and valuation errors to verify how the increase in managerial overconfidence affects valuation errors. Design/methodology/approach - Managerial overconfidence propensity refers to managers having excessive confidence in their position or ability (Hayward and Hambrick, 1997; Park Jin-hee, 2021) and was measured according to Schrand and Zechman (2012). Valuation error refers to a situation where a company's actual stock price differs from its intrinsic value as a result of numerous information asymmetries in the market, and was measured using the measurement method in Rhodes-Kropf et al (2005) study. The sample of this study used companies listed in the capital market for a total of 12 years from 2011 to 2022. Findings - As a result of the verification, there was a significant positive (+) relationship between managerial overconfidence and valuation errors, and this relationship was alleviated as the percentage of foreign shareholders shares or the number of financial analysts they followed increased. It can be interpreted that when the information demands of investors, such as foreign shareholders and financial analysts, increase significantly, managers provide more information to meet investors demands, thereby reducing information asymmetry and leading to a decrease in valuation errors.. Research implications or Originality - Previous studies on overconfidence, among the cognitive characteristics of individual managers, have yielded mixed results. In this study, we conducted a direct empirical analysis of managerial overconfidence using a measure called valuation error, which evaluates numerous information asymmetries in the capital market. This is expected to help stakeholders in the capital market understand the characteristics of managers and recognize their importance. It can also be used as a basis for establishing policies to reduce valuation errors.
