growing every day, making many investors especially interested As usual, stock prices will have sudden ups and downs, they are difficult to control.The stock price crash, which refers to sudden and dramatic fall of stock prices, has become anincreasingly important topic in financial studies due to its effects on investment decisions, risk management, corporate governance and regulatory practices Crash risk, which is the risk of a stock price crash, is an attraction for investors, because unlike the risk derived from symmetric movements, it cannot be mitigated through strategies portfolio diversification (according to Sunder, 2010; Kim and Zhang, 2016) Previous studies have shown that crash risk builds on agency conflicts between managers and shareholders, and focuses primarily on managers' equity and attributes (Kim et al., 2019;Mamun et al., 2020) in addition to external monitoring forces (An and Zhang, 2013; Callen and Fang, 2017; Deng et al, 2020) on crash risk In the past, innovation in the context of CEO succession in family firms has been investigated as well as explored (Jan and Nora and Jan-Philipp and Michael, 2020) , that in many groups the distinctive familial leadership and access to knowledge resources of their predecessors, the transfer of resources and lovers of knowledge, provide a context that allows renew Meanwhile, the relationship between the power or dominance of the CEO and the ownership structure as well as the surrounding risks has not been clearly defined Therefore, in this study, we especially aim to clarify that relationship as accurately as possible, and specifically related to the risk of falling stock prices in the Vietnamese stock market Usually, something new is easy to attract attention and special interest The same thing happens in the economy as well as the stock market in Vietnam Vietnam is a developing country with potential but strong development potential such as real estate, currency, industry, stock market Moreover, the importance of emerging stock markets is gradually increasing gradually attracting more investors Rights always come with responsibilities, this is a basic principle in life as well as corporate governance For the board of directors, who receive the trust of shareholders, employees, customers, stakeholders and society at large, their responsibilities are therefore enormous.In Vietnam, the new chairman is the most powerful person in the company, while abroad, the chief executive officer (CEO) has almost full decision-making power; The CEO can be fired by the board of directors if he does not well, but the CEO is the one who executes, greatly affecting the 0 TOPIC.CEO.OVERPOWER OWNERSHIP.STRUCTURE.AND.STOCK.PRICE.CRASH.RISH.IN.VIETNAMTOPIC.CEO.OVERPOWER

young, holding a very large number of shares, without knowing the real role of this person nothing, or just "name" for enough numbers Many organizations pouring capital into businesses also receive the question of the management board as to what is the role of the investor in their business, so their search for an executive board just needs to be "friendly" to the public It was very difficult for investors alone In developed markets, the highest skill of a CEO is allocating capital and company resources effectively To this, a company's apparatus needs to be decentralized in decisionmaking and responsible for decisions within authority.There is no need for too many people to participate in the decisions, ensuring the leanest business operation of the company At this time, the new CEO has time to strategize capital allocation, because a CEO who only focuses on handling operational issues can not have optimal efficiency, simply put, CEOs Must have the mindset of an investor Thereby it can be seen that in Vietnam there are hardly too many powerful CEOs With an economy with too many bankrupt businesses, especially for our country, the main cause of bankruptcy of businesses is lack of management experience, not knowing how to use people The business is completely dependent on the CEO, when the CEO has no vision, makes the wrong strategy or doesn't know how to use people, the business will have to pay the price When the CEO lacks the necessary management skills to navigate and manage the business to a higher level, the business project he or she is in charge of easily fails The CEO must be able to effectively handle work related to employees, cash flow, business model This is the main cause, stemming from the reliance, coldness in not mentioning that the business leader does not possess management experience, does not understand the market, the inevitable consequence is that it is not sustainable in the current time management cycle, or deviating from business, rushing into businesses beyond their ability, which is certain to fail Even veteran, successful CEOs can get sad endings due to their own arrogance For example, the case of Lord Browne[1] at BP or Jack Welch[2] being stripped of unreasonable privileges by GE As the study of management, accounting, and finance evolves, scholars are increasingly turning their attention to understanding the uncanny effects of top executives' power on operations corporate finance (Clark, Murphy, & Singer, 2014) And before that, there have been many reports on Powerful CEOs and stock price crash risk

well as in the Vietnam market Therefore, in this paper, we examine the impact of CEO power on stock price crash risk (hereinafter referred to as crash risk) This study has both similarities with previous papers and points out its differences It is similar because there have been research models of CEO power, CEO and business owner or the risk of business collapse, but through that similarity, this study will examine the relationship between CEO and CEO combination of relationships and influences between these factors As CEO POWER, OWN STRUCTURE AND STOCK PRICE RISK IN VIETNAM Not only is the topic newer than the research reports that have been posted on reputable forums, the group's report is also different from previous articles in terms of getting research data, data is taken from two exchanges major securities market in Vietnam, the articles used by the group for reference are downloaded from foreign forums such as Sci Hub, ScienceDirect, The variables that the group chooses to use as data to run the model are also different from the articles Previously available in the country, some of the different variables here are NCSKEW, DUVOL, CEOOWN, STATEOWN, BOARD X CEOPRCH, BOARD X AGE, BOARD X CEOOWN, BOARD X SHAREHOLDER From the new data of the group, it will provide readers with a new report not only in the topic, but also with new sources of valuable data for reference Research reports can provide a new source of data for future research papers, as a reference From the new research results, it will create more premise for research on CEOs, businesses, risk of breakdown The method used in this report is to take data based on financial statements and annual reports of 116 enterprises on two Vietnamese stock exchanges, HOSE and HNX Run the model against original papers collected from mainstream sources such as ScienceDirect and Sci Hub to determine the correlation between the paper's variables The study will also provide additional data sources from the financial statements of 116 companies listed on the stock exchange for the following research papers: NCSKEW, DUVOL, CEOOWN, STATEOWN, SHAREHOLDER, BOARD, LEV, The research paper also provides a number of reputable sources for reference, which have been published in forums of scientific research articles Through the article, it can provide more reference data for investors, so that they can choose between CEOs who can create risks for businesses, but bring opportunities to turn prospects and secure CEOs safe but will make the business stereotype, make the business too safe, there is no new transformation Not only investors, the company's board of directors is also the target of this research report, they can have a new perspective on giving power to the CEO, the shares held 0

asymmetry in risk and is important for invesment decisions and risk management Yasir et al (2020),to examine the relationship between CEO power and stock price crash risk, we build the following regression model: = + +∑ + where, crash risk is the risk of stock price decline for company i's stock in year t; CEOPOWER is the sum of the value variable (dummy) CEOPRCH, the percentage of share ownership of CEO- CEOOWN; CEO age - CEOAGE To measure crash risk, we employed two proxies (NCSKEW, DUVOL) following previous studies (Kim et al., 2011; Xu et al., 2014; Zhang et al., 2016) as our main crash risk and CEOPRCH as the CEO's main power variable (Kim et al.2011) The literature of the research paper is referenced in a number of ways CEO power is associated with a higher risk of collapse The association between CEO power and higher risk of collapse keeps control of other drivers or mechanisms for hoarding bad news such as financial opacity (Hutton et al., 2009) Reduce the weight of the negative to positive earnings guidance and lower the negative to positive weighting in their financial statements Overall, to understand the determinants of corporate risk, it is important to look at the structure of a company's decision-making power The coefficients of CEO power are positive when turnover events result in increase in CEO power and are negative when turnover events result in decrease in CEO power Yasir et al.(2020) show: “Studies on CEO characteristics as determinants of crash risk elucidate that: Overconfident executives increase future crash risk (Kim) et al., 2016); incentives from holding CEO options have a weak positive association with collision risk (Kim et al., 2011); and (iii) younger CEOs tend to pose a collision risk (Andreou, Louca, & Petrou, 2016).Previous research (eg, Andreou et al., 2016; Chen et al., 2017a) shows that effective corporate governance can reduce the risk of failure Thereby seeing the impact of corporate governance on the relationship between the risk of collapse and CEO power and the negative impact of stock price risk on CEO power will be reduced by companies have a solid operating system.Through the 0

to the risk of stock price decline The influence of CEO power on pre-collision risk is quite clear Thereby, our team hypothesized the following: CEO power as a positive relationship with on crash risk The relation between crash risk and future CEO power Hypothesize that crash risk is negatively related to future CEO power because CEO power increases crash risk (Mamun et al., 2019) Habib et al (2018) argue that rational firms should limit or eliminate certain factors that increase crash risk after stock price crashes Hence, expect that after price crashes, rational firms curtail CEO power.Through referenced original articles, we see accident risks after CEO changes CEOs with more power will have a higher risk of collapse, and vice versa, CEOs with less power will reduce the risk of change We compare CEOs of companies, these CEOs have similar characteristics but not have absolute power Companies with powerful CEOs are more at risk than similar companies but CEOs don't The CEO is the person responsible for operating and making decisions for the direction of the business, so the CEO's power not only affects the risk of business collapse, but ownership is also an important factor that directly affects the company's business the CEO's decisionmaking process From the above impact, our group boldly hypothesized: Ownership will reduce the negative impact of CEO power on the risk of collapse Measures of DUVOL DUVOL is Down to up volatility (DUVOL) calculated from the equation used to measure the risk of falling stock prices.The DUVOL variable is measured as follows: ( ) = log ( ( ) ) Our measure of stock price crash risk is down-to-up volatility (DUVOL) This measure was developed by Chen et al (2001) and followed by Huttonet al (2009) and Kim et al (2011a, 2011b) To calculate DUVOL, we separate specific weekly returns into down and up weeks Specifically, down (up) weeks refer to those weeks during which firm-specific weekly returns are below (above) the annual average weekly return We calculate DUVOL as the log of the ratio of the standard deviation of firmspecific down weekly returns to the standard deviation of up weekly returns during the fiscal year Similar to Kim et al (2011b) and Kim and Zhang (2016), we estimate our crash risk measures over a 12-month period starting three months after the fiscal year-end 0 TOPIC.CEO.OVERPOWER

of DUVOL After testing and selection, we use random effects regression model to consider the control of unobserved factors Considering the regression table, we have an R-squared index of 0.007, which means that the independent variables affect the dependent variable 0.7%, the other variables are 99.3% Considering the above regression table, we see that the variable CEOPRCH and the variable CEOAGE are positively correlated with crash risk The fact that a CEO holds the chairmanship will increase the executive's power, while also increasing the risk of crash risk Andreou et al (2016), younger CEOs tend to pose a higher crash risk We identify CEO ownership during our sample period, we have 986 observations, recorded 973 samples with changes in CEO power The t-values of DUVOL and NCSKEW are -1.475 and -0.916 respectively,as CEO ownership increases, crash risk is reduced Crash risk and ownership structure In panel and 2, it is found that the variables representing the ownership structure of firms are positively and negatively related to crash risk Variables BOARD,SHAREHOLDER, BOARDxCEOOWN, BOARDxCEOPRCH are all positively correlated with DUVOL and NCSKEW V Conclusion We investigate the role of management power in the downside risk of a company's stock Through the study, we provide evidence that CEO power is positively related to 0 TOPIC.CEO.OVERPOWER
