Academic Papers - Insider Trading
(with R. Jackson and B. Lynch)
While corporate insiders at US-listed, US-domiciled companies must disclose their stock sales electronically within two business days on Form 4, the SEC has exempted insiders at US-listed, foreign-domiciled companies from this requirement (e.g., Astra Zeneca, Alibaba). Instead, these “foreign insiders” report their sales on a paper form mail-filed with the SEC. Using a unique dataset compiled from digitized versions of thousands of paper forms, we examine the stock sales of foreign insiders and compare their trading to that of their US-counterparts. Consistent with a lack of public scrutiny facilitating opportunism, we show that foreign insiders’ stock sales are highly opportunistic, and that opportunistic trading is concentrated in companies that are domiciled in non-extradition countries beyond the reach of US legal authorities: specifically, Russia and China. The average stock sale by foreign insiders affiliated with companies domiciled in these countries is over four times larger than that of US insiders and occurs prior to stock price declines of at least –18%. In our sample, we estimate that insiders at these companies have traded to avoid losses of over $9 billion. Collectively, we interpret our results as suggesting that corporate insiders associated with Chinese and Russian companies listed on US exchanges trade in a highly opportunistic and abusive manner; and that the SEC has unwittingly enabled such trading by exempting these insiders from Form 4 reporting requirements––preventing the market from scrutinizing and disciplining their trading behavior.

The SEC adopted Rule 10b5-1 to provide an affirmative defense against allegations of insider trading to executives whose jobs regularly expose them to material nonpublic information. In this Closer Look, we present evidence on the trading behavior of corporate executives using a unique dataset of over 20,000 10b5-1 plans to show that a subset of executives use these plans to engage in opportunistic, large-scale selling that appears to undermine the purpose of Rule 10b5-1. We identify three “red flags” associated with 10b5-1 abuse: 1) short cooling-off periods, 2) plans that cover a single block trade, and 3) plans that are adopted and commence trading immediately prior to earnings announcements.

One of the hallmarks of the SEC’s investigative process is that it is shrouded in secrecy––only the SEC staff, high-level managers of the company being investigated, and outside counsel are typically aware of active investigations. We obtain novel data on all investigations closed by the SEC between 2000 and 2017––data that was heretofore non-public––and find that such investigations predict economically material declines in future firm performance. Despite evidence that the vast majority of these investigations are economically material, firms are not required to disclose them, and only 19% of investigations are initially disclosed. We examine whether corporate insiders exploit the undisclosed nature of these investigations for personal gain. Despite the undisclosed and economically material nature of these investigations, we find that insiders are not abstaining from trading. In particular, we find a pronounced spike in insider selling among undisclosed investigations with the most severe negative outcomes; and that abnormal selling activity appears highly opportunistic and earns significant abnormal returns. Our results suggest that SEC investigations are often undisclosed, economically material non-public events and that insiders are trading in conjunction with these events. [download]

While the shareholder benefits of audits are well documented, evidence on whether audits can facilitate opportunistic behavior by corporate insiders is scarce. In this paper, we examine whether the audit process facilitates one particular form of opportunism: informed trading by corporate insiders. We focus our analysis on insider trading around the audit report date. We find an increase in trading around the audit report date and that the increase is abnormally large for firms that subsequently report modified opinions. The abnormal increase in trading is concentrated among officers and non-audit committee independent directors, and most pronounced in first-time modified opinions and modified opinions in years where financial results are subsequently restated. These trades are highly opportunistic: they predict restatements, and as a consequence, we show they avoid significant losses. Collectively, our findings provide novel evidence that insiders appear to exploit private information about the audit process––a process ostensibly designed to protect shareholders––for opportunistic gain.

Corporate executives receive a considerable portion of their compensation in the form of equity and, from time to time, sell a portion of their holdings in the open market. Executives nearly always have access to nonpublic information about the company, and routinely have an information advantage over public shareholders. Federal securities laws prohibit executives from trading on material nonpublic information about their company, and companies develop an Insider Trading Policy (ITP) to ensure executives comply with applicable rules. In this Closer Look we examine the potential shortcomings of existing governance practices as illustrated by four examples that suggest significant room for improvement. [download]

We analyze the trading of corporate insiders at leading financial institutions during the 2007 to 2009 financial crisis. We find strong evidence of a relation between political connections and informed trading during the period in which TARP funds were disbursed, and that the relation is most pronounced among corporate insiders with recent direct connections. Notably, we find evidence of abnormal trading by politically connected insiders 30 days in advance of TARP infusions, and that these trades anticipate the market reaction to the infusion. Our results suggest that political connections can facilitate opportunistic behavior by corporate insiders. [download]

Most corporate governance research focuses on the behavior of chief executive officers, board members, institutional shareholders, and other similar parties. Little research focuses on the impact of executives whose primary responsibility is to enforce and shape corporate governance inside the firm. This study examines the role of the general counsel in mitigating informed trading by corporate insiders. We find that insider trading profits and the predictive ability of insider trades for future operating performance are generally higher when insiders trade within firm-imposed restricted trade windows. However, when general counsel approval is required to execute a trade, insiders’ trading profits and the predictive ability of insider trades for future operating performance are substantively lower. Thus, when given the authority, it appears the general counsel can effectively limit the extent to which corporate insiders use their private information to extract rents from shareholders.

While the shareholder benefits of investor conferences are well-documented, evidence on whether these conferences facilitate managerial opportunism is scarce. In this paper, we examine whether some managers opportunistically exploit heightened attention around the conference to “hype” the stock. We find that some managers increase the quantity of voluntary disclosure leading up to the conference; that these disclosures are more positive in tone and increase prices to a greater extent than post-conference disclosures; and that these disclosures are more pronounced when insiders sell their shares immediately prior to the conference. In circumstances where pre-conference disclosures coincide with pre-conference insider selling, we find evidence of a significant return reversal––large positive returns before the conference, and large negative returns after the conference––and that the firm is more likely to be named in a securities class action lawsuit. Collectively, our findings are consistent with some managers hyping the stock prior to the conference. [download]

Academic Papers - Financial Misreporting
(with E. Vagle and M. Stapleton)
Founded in 2017, Luckin Coffee Inc. (“Luckin”) quickly emerged as the fastest growing coffee company in China. Within two years it had surpassed Starbucks’ store count fuelled by equity financing from world-class investors and an “asset-light” store design that promised effortless growth. Luckin went public through a US listing in May 2019 with an app-based business model set to disrupt the coffee industry. Following reported operational successes and several transformational strategic announcements, Luckin’s growth story looked limitless. Yet after 18 months as a public company, Luckin paid $180 million to settle charges of widespread fraud by the Securities and Exchange Commission (SEC) that inflated revenues in excess of 40%.

This paper examines how the ex ante level of public scrutiny influences a manager’s subsequent decision to misreport. The conventional wisdom is that high levels of public scrutiny facilitate monitoring, suggesting a negative relation between scrutiny and misreporting. However, public scrutiny also increases the weight that investors place on earnings in valuing the firm. This in turn increases the benefit of misreporting, suggesting a positive relation. We formalize these two countervailing forces––monitoring and valuation––in the context of a parsimonious model of misreporting. We show that the combination of these two forces leads to a unimodal relation. Specifically, as the level of public scrutiny increases, misreporting first increases, reaches a peak, and then decreases. We find evidence of such a relation across multiple empirical measures of misreporting, multiple measures of public scrutiny, and multiple research designs. [download]

Newly public companies tend to exhibit abnormally high accruals in the year of their initial public offering (IPO). Although the prevailing view in the literature is that these accruals are caused by opportunistic misreporting, we show that these accruals do not appear to benefit managers and instead result from the normal economic activity of newly public companies. In particular, and in contrast to the notion that managers benefit from inflating accruals through an inflated issue price, inflated post-IPO equity values, and increased insider trading profits, we find no evidence of a relation between abnormal accruals and these outcomes. Instead, consistent with these accruals resulting from normal economic activity, we find that these accruals are attributable to the investment of IPO proceeds in working capital and that controlling for the amount of IPO proceeds invested in working capital produces a more powerful accrual-based measure of misreporting.

Prior research argues that a manager whose wealth is more sensitive to changes in the firm’s stock price has a greater incentive to misreport. However, if the manager is risk-averse and misreporting increases both equity values and equity risk, the sensitivity of the manager’s wealth to changes in stock price (portfolio delta) will have two countervailing incentive effects: a positive “reward effect” and a negative “risk effect.” In contrast, the sensitivity of the manager’s wealth to changes in risk (portfolio vega) will have an unambiguously positive incentive effect. We show that jointly considering the incentive effects of both portfolio delta and portfolio vega substantially alters inferences reported in prior literature. Using both regression and matching designs, and measuring misreporting using discretionary accruals, restatements, and SEC Accounting and Auditing Enforcement Releases, we find strong evidence of a positive relation between vega and misreporting and that the incentives provided by vega subsume those of delta. Collectively, our results suggest that equity portfolios provide managers with incentives to misreport when they make managers less averse to equity risk. [download]

This study examines how key market participants — managers and analysts — responded to SFAS 123R’s controversial requirement that firms recognize stock-based compensation expense. Despite mandated recognition of the expense, some firms’ managers exclude it from pro forma earnings and some firms’ analysts exclude it from Street earnings. We find evidence consistent with managers opportunistically excluding the expense to increase earnings, smooth earnings, and meet earnings benchmarks, but no evidence that such exclusion results in an earnings measure that better predicts future firm performance. In contrast, we find that analysts exclude the expense from earnings forecasts when the exclusion increases earnings’ predictive ability for future performance, and opportunism generally does not explain exclusion by analysts incremental to exclusion by managers. Thus, our findings indicate that opportunism is the primary explanation for exclusion of the expense from pro forma earnings and predictive ability is the primary explanation for exclusion from Street earnings. Our findings suggest the controversy surrounding the recognition of stock-based compensation expense may be attributable to cross-sectional variation in the relevance of the expense for equity valuation, as well as to differing incentives of market participants.

Dechow, Myers, and Shakespeare (2009, DMS) finds a negative relation between income from securitization activities and income from non-securitization activities. DMS interprets this finding as indicating that managers use the flexibility available in fair value accounting rules to smooth earnings. We clarify the role of fair value in accounting for asset securitizations, discuss alternative explanations for the evidence presented in DMS, and offer suggestions for future research. We caution against inferring the desirability of any particular accounting method from earnings management research. [download]
Academic Papers - Corporate Disclosure & Capital Markets
(with D. Larcker, B. Lynch, and B. Tayan)
Investors rely on corporate disclosure to make informed decisions about the value of companies they invest in. The COVID-19 pandemic provides a unique opportunity to examine disclosure practices of companies relative to peers in real time about a somewhat unprecedented shock that impacted practically every publicly listed company in the U.S. We examine how companies respond to such a situation, the choices they make, and how disclosure varies across industries and companies. We ask: What motivates some companies to be forthcoming about what they are experiencing, while others remain silent? Do differences in disclosure reflect different degrees of certitude about how the virus would impact businesses, or differences in management perception of its obligations to shareholders? What insights will companies learn to prepare for future outlier events? [download]

This study examines the effect of the Jumpstart Our Business Startups Act (JOBS Act) on information uncertainty in IPO firms. The JOBS Act creates a new category of issuer, the Emerging Growth Company (EGC), and exempts EGCs from several disclosures required for non-EGCs. Our findings are consistent with proprietary cost concerns motivating EGCs to eliminate some of the previously mandatory disclosures, which increases information uncertainty in the IPO market, attracts investors who rely more on private information, and leads EGCs to provide additional post-IPO disclosures to mitigate the increased information uncertainty. Our results also are consistent with agency explanations, whereby EGCs exploit the JOBS Act provisions to avoid compensation related disclosures, which results in larger IPO underpricing for such firms. Overall, we provide evidence on how reduced mandatory disclosure affects the IPO market. [download]

This paper investigates the market reaction to recent legislative and regulatory actions pertaining to corporate governance. The managerial power view of governance suggests that executive pay, the existing process of proxy access, and various governance provisions (e.g., staggered boards and CEO-chairman duality) are associated with managerial rent extraction. This perspective predicts that broad government actions that reduce executive pay, increase proxy access, and ban such governance provisions are value enhancing. In contrast, another view of governance suggests that observed governance choices are the result of value-maximizing contracts between shareholders and management. This perspective predicts that broad government actions that regulate such governance choices are value destroying. Consistent with the latter view, we find that the abnormal returns to recent events relating to corporate governance regulations are, on average, decreasing in CEO pay, decreasing in the number of large blockholders, decreasing in the ease by which small institutional investors can access the proxy process, and decreasing in presence of a staggered board.

In 2008, the SEC published guidance allowing firms to use corporate websites as an alternative disclosure channel to EDGAR. While the information content and market reaction to traditional disclosure channels such as EDGAR filings and press releases are well-documented, evidence on corporate websites as a disclosure channel is scarce. In this paper, we take the first step toward shedding light on corporate websites as an important but unregulated source of information to investors. We begin by developing a novel measure of corporate website content. We then identify large changes in corporate websites content that do not occur in close proximity to EDGAR filings and press releases and examine what effect, if any, these standalone changes in website content have on markets and information production by analysts and journalists. Using standard event study methods, we find that standalone changes in the corporate websites provide significant value-relevant information to investors, reduce information asymmetry, and precede significant revisions in analyst forecasts and increases in media coverage. Collectively, our findings indicate that corporate websites are an economically significant source of new information to markets and information intermediaries that supplements traditional disclosure channels considered in prior literature.

Prior research generally interprets complex language in firms’ disclosures as indicative of managerial obfuscation. However, complex language can also reflect the provision of complex information, e.g., informative technical disclosure. As a consequence, linguistic complexity commingles two latent components — obfuscation and information — that are related to information asymmetry in opposite directions. We develop a novel empirical approach to estimate these two latent components within the context of quarterly earnings conference calls. We validate our estimates of these two latent components by examining their relation to information asymmetry. Consistent with our predictions, we find that our estimate of the information component is negatively associated with information asymmetry while our estimate of the obfuscation component is positively associated with information asymmetry. Our findings suggest that future research on linguistic complexity can construct more powerful tests by separately examining these two latent components of linguistic complexity. [download]

A growing literature documents that complex financial statements negatively affect the information environment. In this paper, we examine whether managers use voluntary disclosure to mitigate these negative effects. Employing cross-sectional and within-firm designs, we find a robust positive relation between financial statement complexity and voluntary disclosure. This relation is stronger when liquidity decreases around the filing of the financial statements, is stronger when firms have more outside monitors, and is weaker when firms have poor performance and greater earnings management. We also examine the relation between financial statement complexity and voluntary disclosure using two quasi-natural experiments. Employing a generalized difference-in-differences design, we find firms affected by the adoption of complex accounting standards (e.g., SFAS 133 and SFAS 157) increase their voluntary disclosure to a greater extent than unaffected firms. Collectively, these findings suggest managers use voluntary disclosure to mitigate the negative effects of complex financial statements on the information environment. [download]

This paper examines when information asymmetry among investors affects the cost of capital in excess of standard risk factors. When equity markets are perfectly competitive, information asymmetry has no separate effect on the cost of capital. When markets are imperfect, information asymmetry can have a separate effect on firms’ cost of capital. Consistent with our prediction, we find that information asymmetry has a positive relation with firms’ cost of capital in excess of standard risk factors when markets are imperfect and no relation when markets approximate perfect competition. Overall, our results show that the degree of market competition is an important conditioning variable to consider when examining the relation between information asymmetry and cost of capital.

This study examines the sources of credit risk associated with asset securitizations and whether credit rating agencies and the bond market differ in their assessment of this risk. Measuring credit risk using credit ratings, we find the securitizing firm’s credit risk is positively related to the firm’s retained interest in the securitized assets and unrelated to the portion of the securitized assets not retained by the firm. Measuring credit risk using bond spreads, we find the securitizing firm’s credit risk is positively related to both the firm’s retained interest in the assets and the portion of the securitized assets not retained by the firm. Additionally, our findings indicate the bond market does not distinguish between the retained and non-retained portions of the securitized assets when assessing the credit risk of the securitizing firm. These different assessments of the sources of credit risk associated with asset securitizations provide insight into ongoing controversies surrounding the financial reporting for asset securitizations and the efficacy of credit ratings.

This study develops and tests a simple model of voluntary disclosure where managers can choose to withhold (i.e., redact) certain elements from mandatory disclosure. We consider a setting where mandatory disclosure is a disaggregated disclosure (e.g., a financial statement), voluntary disclosure is an aggregate disclosure (e.g., an earnings forecast), and the costs of each type of disclosure are distinct. In this setting, we show that managers endogenously substitute between the two types of disclosure—managers that chose to withhold information from mandatory disclosure are more likely to provide voluntary disclosure. We test our predictions using a comprehensive sample of mandatory disclosures where the SEC allows the firm to redact information that would otherwise jeopardize its competitive position. Consistent with our predictions, we find strong evidence that redacted mandatory disclosure is associated with greater voluntary disclosure. [download]

However, we find no evidence that ACSI predicts long-run returns.These results suggest thatcustomer satisfaction information is value-relevant, but are also consistent with Jacobson and Mizik’s (2009) conclusion that mispricing of ACSI information, if present at all, is limited.

We extend the CAPM to a setting where a firm reports earnings prior to selling shares to investors. We show that an entrepreneur, as representative of a firm's initial owners, will choose to report earnings that asymmetrically reflect future cash flow. In modeling the entrepreneur's reporting choice, we deliberately abstract away from the stewardship role of accounting. In our model, the sole purpose of reported earnings is to facilitate valuation by the firm's equity investors. Nevertheless, we show that a firm's earnings will reflect future cash flow to a greater (lesser) extent in bad states (good states) –– when that cash flow is anticipated to be low (high). Importantly, we also show that the asymmetry in reporting generates asymmetry in the firm's systematic risk. When a firm's earnings reflect future cash flow to a greater extent in bad states, the firm's covariance with the market portfolio will be lower in bad states. [download]

Classical models of voluntary disclosure feature two economic forces: the existence of an adverse selection problem (e.g., a manager possesses some private information) and the cost of ameliorating the problem (e.g., costs associated with disclosure). Traditionally these forces are modelled independently. In this paper, we use a simple model to motivate empirical predictions in a setting where these forces are jointly determined––where greater adverse selection entails greater costs of disclosure. We show that joint determination of these forces generates a pronounced non-linearity in the probability of voluntary disclosure. We find that this non-linearity is empirically descriptive of multiple measures of voluntary disclosure in two distinct empirical settings that are commonly thought to feature both private information and proprietary costs: capital investments and sales to major customers.

Several recent empirical papers assert that the decision to disclose an earnings forecast shortly before the actual earnings announcement reveals only short-term information and is therefore unlikely to entail proprietary costs. Using a simple dynamic model of voluntary disclosure, we show that the decision to disclose a short-term earnings forecast reveals managers’ private information about long-term future performance. We test the predictions of the model empirically and find that the decision to disclose a short-term earnings forecast predicts earnings three years beyond the forecasted period, and that the predictive ability is incremental to short-term earnings itself. Consistent with the predictions of our model, we find that the predictive ability of the short-term forecast decision for long-term performance is higher when short-term performance is poor; is lower when managers have short horizons; and is lower when proprietary costs of revealing long-term performance is high. Our analysis suggests that – despite its short horizon – the decision to provide a short-term earnings forecast contains significant information about long-term performance and thus can entail significant proprietary costs.

We extend a standard, rational expectation model of trade to incorporate the possibility of individual investors delegating their trades to an informed financial intermediary. In the presence of delegated trade, we show that a firm's risk premium is a function of both the firm's exposure to a common risk factor and idiosyncratic characteristics of the firm's information environment. We show that even in a large economy, priced risks can manifest in the form of both idiosyncratic firm characteristics and common risk factors; as a consequence, factor-based asset pricing tests cannot rule out that a particular risk is priced.

We show theoretically and empirically that measurement error can bias in favor of falsely rejecting a true null hypothesis (i.e., a “false positive”) and that regression models with high-dimensional fixed effects can exacerbate measurement error bias and increase the likelihood of false positives. We replicate inferences from prior work in a setting where we are able to directly observe the amount of measurement error, and show that the combination of measurement error and fixed effects materially inflates coefficients and distorts inferences. We provide researchers with a simple diagnostic tool to assess the possibility that the combination of measurement error and fixed effects might give rise to a false positive, and encourage researchers to triangulate inferences across multiple empirical proxies and multiple fixed effect structures.

This paper reviews the empirical methods used in the accounting literature to draw causal inferences. Recent years have seen a burgeoning growth in the use of methods that seek to exploit as-if random variation in observational settings—i.e., “quasi-experiments.” We provide a synthesis of the major assumptions of these methods, discuss several practical considerations relevant to the application of these methods in the accounting literature, and provide a framework for thinking about whether and when quasi-experimental and non-experimental methods are well-suited for addressing causal questions of interest to accounting researchers. While there is growing interest in addressing causal questions within the literature, we caution against the idea that one should restrict attention to only those causal questions for which there are quasi-experiments. We offer a complementary approach for addressing causal questions that does not rely on the availability of a quasi-experiment, but rather relies on a combination of economic theory, developing and falsifying alternative explanations, triangulating results across multiple settings, measures, and research designs, and caveating results where appropriate.

On December 5th and 6th 2014, the Stanford Graduate School of Business hosted the Causality in the Social Sciences Conference. The conference brought together several distinguished speakers from philosophy, economics, finance, accounting and marketing with the bold mission of debating scientific methods that support causal inferences. We highlight key themes from the conference as relevant for accounting researchers. First, we emphasize the role of formal economic theory in informing empirical research that seeks to draw causal inferences, and offer a skeptical perspective on attempts to draw causal inferences in the absence of well-defined constructs and assumptions. Next, we highlight some of the conceptual limitations of quasi-natural experimental methods that were discussed at the conference, and discuss the role of structural estimation. Finally, we illustrate many of the points from the conference by estimating a novel, theoretically grounded measure of disclosure costs. [download]

We review and evaluate the methods commonly used in the accounting literature to correct for cross-sectional and time-series dependence. While much of the accounting literature studies settings where variables are cross-sectionally and serially correlated, we find that the extant methods are not robust to both forms of dependence. Contrary to claims in the literature, we find that the Z2-statistic and Newey-West corrected Fama-MacBeth do not correct for both cross-sectional and time-series dependence. We show that extant methods produce misspecified test statistics in common accounting research settings, and that correcting for both forms of dependence substantially alters inferences reported in the literature. Specifically, several findings in the cost of equity capital literature, the cost of debt literature, and the conservatism literature appear not to be robust to the use of well-specified test statistics.
