CEO Overconfidence and Stock Price Crash Risk

This study examines the association between chief executive officer (CEO) overconfidence and future stock price crash risk. Overconfident managers overestimate the returns to their investment projects and misperceive negative net present value (NPV) projects as value creating. They also tend to ignore or explain away privately observed negative feedback. As a result, negative NPV projects are kept for too long and their bad performance accumulates, which can lead to stock price crashes. Using a large sample of firms for the period 1993–2010, we find that firms with overconfident CEOs have higher stock price crash risk than firms with nonoverconfident CEOs. The impact of managerial overconfidence on crash risk is more pronounced when the CEO is more dominant in the top management team and when there are greater differences of opinion among investors. Finally, it appears that the effect of CEO overconfidence on crash risk is less pronounced for firms with more conservative accounting policies.     

Is Real Earnings Smoothing Harmful? Evidence from Firm‐Specific Stock Price Crash Risk

This study examines whether and when real earnings smoothing influences firm‐specific stock price crash risk. Using a sample of U.S. public firms for the years 1993 through 2014, we find real earnings smoothing to be positively associated with firm‐specific stock price crash risk. This finding is consistent with the view that real earnings smoothing helps managers withhold bad news, keep poor‐performing projects, conceal resource diversion, and engage in ineffective risk management, which increases crash risk. Further, we find a stronger relation between crash risk and real earnings smoothing when firm uncertainty is higher, product market competition is lower, and balance sheet constraint is higher. Overall, our study suggests that real earnings smoothing destroys shareholder value in that it increases stock price crash risk.     

Crash Risk and the Auditor–Client Relationship

This study examines whether the term of the auditor–client relationship (i.e., auditor tenure) is associated with future stock price crash risk measured both ex ante and ex post. Using a large sample of U.S. public firms with Big 4 auditors, we find robust evidence that auditor tenure is negatively related to one‐year‐ahead stock price crash risk. The evidence is consistent with monitoring‐by‐learning where development of client‐specific knowledge over the term of the auditor–client relationship enhances auditors’ ability to detect and deter bad news hoarding activities by clients, thereby reducing future crash risk. This result holds even after controlling for endogeneity of the tenure/crash risk relation. We further provide evidence indicating that option market investors do not fully incorporate the information contained in the term of auditor–client relationship in predicting future stock price crash risk. Our empirical results have important policy implications for regulators concerned with ensuring auditor independence.     

Financial Reporting Opacity and Expected Crash Risk: Evidence from Implied Volatility Smirks

The recent financial crisis has stimulated a renewed interest in understanding the determinants of stock price crash risk (i.e., left tail risk). Recent research shows that opaque financial reports enable managers to hide and accumulate bad news for extended periods. When the accumulated bad news reaches a certain tipping point, it will be suddenly released to the market at once, resulting in an abrupt decline in stock price (i.e., a crash). This study extends this line of research by examining the impact of financial reporting opacity on perceived or expected crash risk. Prominent economists, such as Olivier Blanchard, argue that removing the perception of tail risks (in addition to realized tail risks) is crucial in restoring investor confidence and stabilizing the stock market. Using the steepness of option implied volatility skew as a proxy for perceived crash risk, we find that accrual management, the presence of financial statement restatements, and auditor‐attested internal control weakness are all positively and significantly associated with the level of perceived crash risk. Our results suggest that improving financial reporting transparency is an important mechanism for firms and policymakers to reduce the perception of tail risks and stabilize the stock market.     

Readability of 10‐K Reports and Stock Price Crash Risk

This study shows that less readable 10‐K reports are associated with higher stock price crash risk. The results are consistent with the argument that managers can successfully hide adverse information by writing complex financial reports, which leads to stock price crashes when the hidden bad news accumulates and reaches a tipping point. Cross‐sectional analyses show that the effect of financial reporting complexity on crash risk is more pronounced for firms with persistent negative earnings news or transitory positive earnings news, greater chief executive officer stock option incentives, or lower litigation risk. Finally, accrual manipulation appears to be positively related to crash risk, even since the Sarbanes‐Oxley Act, if the manipulation is accompanied by complex 10‐K reports.     

Can Shareholders Be at Rest after Adopting Clawback Provisions? Evidence from Stock Price Crash Risk

Using a propensity score matched sample and a difference‐in‐differences research design, we find that stock price crash risk increases after a firm voluntarily incorporates clawback provisions in executive officers' compensation contracts. This heightened crash risk is concentrated in adopters that increase upward real activities‐based earnings management and those that reduce the readability of 10‐K reports. Based on cross‐sectional analyses, we also find that the increased crash risk is more pronounced for adopters with high ex ante fraud risk, low‐ability managers, high CEO equity incentives, and low dedicated institutional ownership. Collectively, our results suggest that the clawback adoption per se does not curb managerial opportunism but rather induces managers to use alternative channels for concealing bad news, which may contribute to a greater stock price crash risk; and the increase in crash risk is more likely in cases where incentives are strong or monitoring is weak. Our results should be of interest to regulators and policymakers considering the effects of clawback adoption on the investing public.     

Conditional Conservatism and Debt versus Equity Financing

Extant research suggests that conditional conservatism reduces information asymmetry between a firm and its shareholders as well as its debtholders. However, there is little evidence on whether conditional conservatism reduces information asymmetry differentially for shareholders and debtholders. We use the setting of a firm's choice between equity versus debt when it seeks a significant amount of external financing to examine this research question. We find that when firms raise a significant amount of external financing, the use of equity (versus debt) increases with the level of conservatism. We also find that the reduction in cost of equity associated with conservatism is greater for equity issuers than for debt issuers, but find no such difference when we examine cost of debt. In addition, we find that the positive effect of conservatism on the choice of equity issuance (versus debt issuance) is accentuated when the information asymmetry between the firm and its shareholders is more severe. Overall, our results suggest that conservatism reduces information asymmetry more between firms and shareholders than between firms and debtholders.     

货币政策、股票流动性与股票价格暴跌风险

目前中国股市还存在较多制度性缺陷,股价波动频繁且暴跌风险较高。本文以2003年至2013年中国A股上市公司为样本,检验作为激发机制的货币政策以及作为外部生成机制的股票流动性对中国股票价格暴跌风险的影响。研究发现：股票流动性与公司股票价格暴跌风险具有显著的敏感性,即随着股票流动性的下降,公司股票价格暴跌风险显著上升;货币政策越宽松,股票价格暴跌的风险越大;而且宽松的货币政策增强了股票流动性与股票价格暴跌风险的敏感性。区分市场势态的进一步分析表明,市场为熊市时,股票流动性对股票价格暴跌风险的影响更显著,货币政策的放松越容易激化股票价格暴跌风险,且对股票流动性与股票价格暴跌风险的敏感性的放大作用更为突出。     

The Link between Earnings Conservatism and the Price‐to‐Book Ratio*

We hypothesize and find that (1) earnings conservatism, the tendency of firms to recognize bad news in earnings on a more timely basis than good news, is substantially greater in portfolios of firms with lower price‐to‐book ratios than in portfolios of firms with higher price‐to‐book ratios; and (2) the negative association between earnings conservatism and the price‐to‐book ratio stems primarily from the accrual component of earnings, not the operating cash flow component of earnings. Our results suggest that studies using earnings‐returns associations to investigate cross‐sectional or time‐series differences in earnings conservatism risk drawing erroneous inferences unless the research designs control for cross‐sectional or time‐series variation in price‐to‐book ratios.     

Hedge Fund Intervention and Accounting Conservatism

Hedge fund intervention has been associated with many positive corporate changes and is an important vehicle for informed shareholder monitoring. Effective monitoring has also been positively associated with accounting conservatism. Building upon these prior results, we predict an increase in accounting conservatism after hedge fund intervention. We use a large sample of hedge fund activist events and identify control firms with similar likelihoods of being targeted using the propensity score matching method to apply difference‐in‐difference tests. We find that when hedge fund activists have relatively large ownership and sufficient time to exert their monitoring power, target firms experience significant increases in conditional conservatism. CFO turnovers, upward/lateral auditor switches, and improvements in audit committee independence after intervention are accompanied by greater increases in conditional conservatism. Finally, we find greater increases in conditional conservatism when there is a lack of monitoring by dedicated institutional investors before the intervention. Our study suggests that hedge fund activists improve accounting monitoring tools and thus adds important new evidence on the effectiveness of shareholder monitoring on accounting practices.     

Do politically connected independent directors matter? Evidence from mandatory resignation events in China

This paper investigates the contributions of politically connected independent directors to shareholder value by examining stock price reactions to their mandatory resignations. Employing an event study, we find that, if a private firm loses its politically connected independent director due to mandatory resignation, its stock price drops 4.61% on average within ten trading days, compared with control firms. We observe that, compared with independent directors from academia, politically connected independent directors are absent from more board meetings and are reluctant to express dissenting opinions even if they attend meetings. So the negative stock price reaction cannot be mainly explained by the loss of supervisory functions after politically connected independent directors were forced to resign from positions. By employing DID estimation, we further find that the economic benefits obtained by private firms decrease after the mandatory resignation. The heterogeneity and robustness checks further confirm that private firms indeed were unable to get the same amount of economic benefits from the government as before, which provides a reasonable explanation for the negative stock price reaction after mandatory resignations of politically connected independent directors.

Corporate Tax Aggressiveness and Insider Trading

We examine the association between corporate tax aggressiveness and the profitability of insider trading under the assumption that insider trading profits reflect managerial opportunism. We document that insider purchase profitability, but not sales profitability, is significantly higher on average in more tax aggressive firms. We also find that the positive association between tax aggressiveness and insider purchase profitability is attenuated for firms with more effective monitoring and is accentuated for firms with a more opaque information environment. In addition, we provide empirical evidence that tax aggressiveness is significantly associated with greater insider sales volume in the fiscal year prior to a stock price crash. Finally, we find that the association between tax aggressiveness and insider purchase profitability weakens after the introduction of FIN 48, consistent with the increased transparency of tax positions under the new disclosure requirement reducing insiders' information advantage and hence their ability to profit from insider trading. To the extent that insider trading profits reflect managerial opportunism, our results are consistent with managers exploiting the opacity arising from tax aggressive activities to extract rent from shareholders, particularly those shareholders who sold their shares to the managers. Our findings are particularly important in light of the number of studies relying on the agency view of tax avoidance to develop arguments or to draw inferences.     

股价崩盘风险、信息透明度与资本结构偏离度——基于沪深A股数据的实证分析

Loan Sales and Borrowers’ Accounting Conservatism

We examine whether initial loan sales in the secondary loan market relate to borrowing firms’ accounting conservatism. We find that borrowing firms exhibit a significant decline in accounting conservatism after the initial loan sales. We show that the decline in borrower conservatism is more pronounced for firms that borrow from lenders with lower monitoring incentives and for firms that have lower incentives to supply conservatism. The baseline results are robust to a battery of sensitivity tests. Collectively, we provide corroborative evidence that lead lenders’ monitoring incentives enforce accounting conservatism in the private debt market, and that lead lenders play a more prominent role than secondary loan market participants in shaping corporate (conservative) reporting.     

纵向兼任高管能降低股价崩盘风险吗?

纵向兼任高管究竟会加强大股东对管理层的监督,减少管理层机会主义行为,提升公司治理水平;还是会强化大股东对上市公司的控制,提升其私有权收益的获取能力,增加企业风险？为此,文章将以2007年-2017年中国A股上市公司为研究样本,探究纵向兼任高管如何影响企业的股价崩盘风险。研究发现,纵向兼任高管显著降低了公司未来股价崩盘风险;在进行Heckman两阶段模型、倾向得分匹配等稳健性检验后,这一结论依然成立。同时,文章进一步研究发现,纵向兼任高管在"监督效应"和"更少掏空效应"共同作用下降低了股价崩盘风险;且当纵向兼任高管权力越大时,即纵向兼任董事长时,对公司未来股价崩盘风险的降低作用越明显。文章不但深化了股价崩盘风险影响因素的研究,而且有助于我们全面认识纵向兼任高管这一关系在公司治理中的作用,这对于完善公司治理、防范股价崩盘风险,进而促进我国资本市场的健康发展有重要的意义。     

Gender Differences in Financial Reporting Decision Making: Evidence from Accounting Conservatism

This paper investigates the effect of CFO gender on corporate financial reporting decision making. Focusing on firms that experience changes of CFO from male to female, the paper compares the firms' degree of accounting conservatism between pre‐ and post‐transition periods. We find that female CFOs are more conservative in their financial reporting. In addition, we find that the relation between CFO gender and conservatism varies with the level of various firm risks, including litigation risk, default risk, systematic risk, and CFO‐specific risk such as job security risk. We further find that the risk aversion of female CFOs is associated with less equity‐based compensation, lower firm risk, a higher tangibility level, and a lower dividend payout level. Overall, the study provides strong support for the notion that female CFOs are more risk averse than male CFOs, which leads female CFOs to adopt more conservative financial reporting policies.     

The Price of Being Foreign: Stock Market Penalties Associated with Accounting Irregularities for U.S.-Listed Foreign Firms

We examine the stock market consequences of disclosing accounting irregularities for U.S.-listed foreign firms. After controlling for the severity of the irregularity and other firm characteristics, we find that foreign firms experience significantly more negative short-window stock market reactions following irregularity announcements than do U.S. firms. Moreover, for a subsample of 64 irregularities of foreign firms that are listed on both a U.S. and home country stock exchange, we find evidence that restating firms' U.S. investors react more negatively to the same irregularity than their home country investors. This differential market reaction appears related to firm-specific information risks that are greater for foreign firms than U.S. firms. Collectively, consistent with the reputational bonding hypothesis in prior literature, our results suggest that accounting irregularities cause U.S. investors to reassess the information risk associated with foreign firms.     

The Effect of Short Selling on Market Reactions to Earnings Announcements*

This paper examines the effect of the inherent demand implied by short interest by studying how stock price reactions to earnings announcements depend on the level of short interest. We find that, for extreme good and bad news events, the inherent demand increases stock prices around the earnings announcement date, with the effect being stronger for good news relative to bad news. Specifically, the initial market reaction to an extreme positive earnings surprise is larger for firms with high levels of short interest. On the other hand, for an extreme negative earnings surprise event, the initial market reaction is less negative for heavily shorted firms. Furthermore, we find that the post‐earnings‐announcement drift is smaller (larger) in magnitude for extreme positive (negative) earnings surprises for the heavily shorted firms.     

Institutional Ownership and the Extent to which Stock Prices Reflect Future Earnings*

Articles in the financial press suggest that institutional investors are overly focused on current profitability, which suggests that as institutional ownership increases, stock prices reflect less current period information that is predictive of future period earnings. On the other hand, institutional investors are often characterized in academic research as sophisticated investors and sophisticated investors should be better able to use current‐period information to predict future earnings compared with other owners. According to this characterization, as institutional ownership increases, stock prices should reflect more current‐period information that is predictive of future period earnings. Consistent with this latter view, we find that the extent to which stock prices lead earnings is positively related to the percentage of institutional ownership. This result holds after controlling for various factors that affect the relation between price and earnings. It also holds when we control for endogenous portfolio choices of institutions (e.g., institutional investors may be attracted to firms in richer information environments where stock prices tend to lead earnings). Further, a regression of stock returns on order backlog, conditional on the percentage of institutional ownership, indicates that institutional owners place more weight on order backlog compared with other owners. This result is consistent with institutional owners using non‐earnings information to predict future earnings. It also explains, in part, why prices lead earnings to a greater extent when there is a higher concentration of institutional owners.
