Abstract CEO Overconfidence plays an important role in determining company performance, especially in the Emerging Market Asia period 2010-2019 in the manufacturing, energy, health, and technology This study uses secondary data taken from Refinitiv Eikon Financial Analysis. This study aims to determine the effect of managerial overconfidence on company performance as proxied by Return on Asset (ROA). Tobin's Q, and Debt to Equity Ratio (DER). This study uses the Principal Component Analysis (PCA) technique and panel data regression. The results of the study indicate that managerial overconfidence has a significant effect on ROA. However, managerial overconfidence does not have a significant effect on Tobin's Q and DER. This explains that managerial overconfidence can directly affect company performance. Keywords Managerial Overconfidence. Return On Asset. TobinAos Q. Debt to Equity Ratio. Principle Component Analysis. INTRODUCTION The current business conditions full of uncertainty and vulnerability due to the COVID-19 pandemic have forced CEOs and their management teams to manage company performance as optimally as possible (McKinsey, 2. At the same time, this condition requires the management team to have high self-confidence in order to mitigate the various risks that arise effectively and efficiently (Kunz & Sonnenholzner, 2. The consequences of the challenges faced require the management team to improve the company's performance by actively innovating so that the company can compete in an ever-changing environment (Taouab & Issor, 2. Overconfidence is one of the CEO attributes that has received a lot of attention from experts because it can affect the CEO's ability to make decisions (Heavey et al. , 2. Selfconfidence is an important characteristic because to some extent it can help run a company successfully (Johnson & Fowler, 2. However, if this self-confidence turns into overconfidence, which refers to being more confident than is justified by reality. (Chen et al. and causes individuals to overestimate their performance and the accuracy of their predictions (Gutierrez et al. , 2. , then there will be significant consequences for the company's performance (Malmendier & Tate, 2. Thus, the attribute of overconfidence has a major impact on the determination and implementation of corporate strategy (Huang et al. , 2. This business phenomenon has prompted a great deal of research into the impact of CEO overconfidence on strategic risk setting (Burkhard, 2. Company performance is the main criteria in determining success in achieving company goals (Quigley & Graffin, 2. Company performance must be optimized effectively and efficiently because performance is a measure of the company's success which will be the initial part seen by investors and become a consideration in decision making SINOMICS JOURNAL | VOLUME 3 ISSUE 5 .

(Pranata et al. , 2. Performance assessment is reflected in the form of corporate responsibility and corporate obligations in reporting performance and performance achievements on the use of resources (Hastuti, 2. The structure and development of a company that can increase the success of a company is also influenced by the company's performance (Azizah & Amin, 2. Overconfidence bias causes CEOs to consider very high probabilities of their Overconfidence bias also distorts capital structure decisions (Chen et al. , 2. The amount of debt borrowed, the choice of short-term or long-term debt, and the choice between equity, debt, or cash are affected by the presence of overconfidence among CEOs. Researchers in behavioral corporate finance have documented that for a given level of investment needs, the sensitivity of investment cash flows is much higher for overconfident CEOs than for rational CEOs (Malmendier & Tate, 2. According to Kharas and Maddison . in the McKinsey Global Institute Cityscope 2. 0, emerging markets will drive global growth over the next 20 years. By 2025, global consumption as a whole is expected to reach $62 trillion, double the 2013 level, and half of this increase will come from developing countries. By 2025, that number will increase to more than half. Taking into account population growth, there will be an additional 1. billion consumers, most of whom will live in developing regions. According to the OECD Emerging Markets Network Report . , the global economy is expected to remain sluggish due to a variety of factors, including RussiaAos fullscale invasion of Ukraine, persistent supply chain bottlenecks, inflationary pressures, tighter monetary policy and rising risk perceptions. Global GDP growth is projected to decline from 9 percent in 2021 to 3. 2 percent in 2022, and further to 2. 6 percent in 2023. In Figure 1. Developing Asia consists of China. India. Indonesia. Hong Kong. Malaysia. Taiwan, the Philippines. Singapore. Thailand and Vietnam. Until now, there are still differences in research results regarding the influence of managerial overconfidence on company performance. Several researchers such as Burkhard et al. Mundi and Kaur . found that managerial overconfidence has a significant effect on company performance. While other researchers such as Candy and Delfina . did not find a significant effect of managerial overconfidence on company performance. The existence of this research gap provides an opportunity for the author to further research the effect of managerial overconfidence on company performance. METHOD In research, data plays an important role in determining the design and analyzing research because data is the main input used and processed. The source and type of data in this study are secondary data. Secondary data is a data source that does not directly provide data to data collectors, for example through other people or documents (Sugiyono, 2. The research data used is a combination of cross-section and time series data of energy, health, manufacturing, and technology companies in Emerging Market Asia from 2010 to 2019 obtained from Refinitiv Eikon. This study took a population of 10 companies from SINOMICS JOURNAL | VOLUME 3 ISSUE 5 . SINOMICSJOURNAL.

Discussion of The Influence of Managerial Overconfidence on Firm Performance The Influence of Managerial Overconfidence on Company Performance (ROA) This study shows a positive influence between Managerial Overconfidence and company performance as measured by Return On Asset. This shows thatbiases and heuristics can produce acceptable solutions to problems in an effective and efficient manner (Busenitz & Barney, 1. and help CEOs manage unpredictable and complex situations (Simon et , 2. Such processes are essential for making strategic decisions, which are often difficult, urgent, and full of uncertainty (Artinger et al. , 2. The results of this study are supported by several previous studies that also found a positive effect between managerial overconfidence and ROA (Chen et al. , 2015. Picone et al. , 2014. Reyes et al. , 2. Basically, the conventional perspective in BDT highlights the detrimental consequences of CEO overconfidence on strategic choices, thus negatively impacting organizational performance. On the other hand, new advances in BDT suggest that CEO overconfidence can help in strategic choices, thus improving firm performance especially ROA. SINOMICS JOURNAL | VOLUME 3 ISSUE 5 . SINOMICSJOURNAL. COM ISSN . : 2829-7350 | ISSN. : 2963-9441 The Influence of Managerial Overconfidence on Company Performance (Tobin's Q) This study shows that there is no influence between Managerial Overconfidence on company performance as measured by Tobin's Q. This shows that CEO Overconfidence does not have a direct influence on company performance, especially on Tobin's Q (Sumunar & Djakman, 2. This occurs because there are other influencing factors, such as company size, asset growth, and sales growth of a company. Thus, overconfidence can result in strategic assessments that are not well thought out and are not appropriate. The results of this study are supported bySeveral previous studies also found that there was no influence between managerial overconfidence and Tobin's Q (Malmendier & Tate, 2008. Park et al. PavicAeviN & Keil, 2. The Influence of Managerial Overconfidence on Company Performance (DER) This study shows that there is no influence between Managerial Overconfidence on company performance as measured by the Debt to Equity Ratio. This shows that companies that have overconfident managers tend to have lower debt levels (Ting et al. , 2. This happens because overconfident CEOs assume that new projects will increase the value of the company so they will choose to reduce debt levels. In addition, there are other factors such as education which show that the higher the level of education, the more knowledge they have, making them more careful and more rational. Rational CEOs prefer equity as their source of financing. The results of this study are supported bySeveral previous studies also found that there was no influence between managerial overconfidence and DER (Murhadi. Park et al. , 2. Several studies in the last decade have focused on debt conservatism by analyzing CEO behavior. Sunder et al. study how overconfidence among executives affects debt covenant formulation. They find that firms run by overconfident CEOs prefer conservative debt-raising policies and suggest that appropriate debt covenant formulation can mitigate overconfidence among CEOs. Malmendier et al. suggest that overconfident CEOs issue debt conservatively relative to the tax benefits available. Huang-Meier et al. document evidence of debt conservatism by optimistic CEOs. They suggest that debt conservatism is unrelated to cash holdings. CONCLUSION This study examines the influence of Managerial Overconfidence on Company Performance in the period 2010-2019, so the following conclusions can be drawn: Managerial Overconfidence has a significant influence on Company Performance (ROA) in the Emerging Market Asia region in the 2010-2019 period. Managerial Overconfidence does not have a significant influence on Company Performance (Tobin's Q) in the Emerging Market Asia region in the 2010-2019 period. Managerial Overconfidence does not have a significant influence on Company Performance (DER) in the Emerging Market Asia region in the 2010-2019 period. SINOMICS JOURNAL | VOLUME 3 ISSUE 5 .
