The effect of stock price on discretionary disclosure

I examine the impact of exogenous changes in stock prices on voluntary disclosure. Specifically, I investigate whether stock price declines prompt managers to voluntarily disclose firm-value-related information (management forecasts) that was withheld prior to the decline because it was unfavorable but became favorable at a lower stock price. Consistent with my predictions, I find that managers are more likely to release good-news forecasts following larger stock price declines but that there is no association between the likelihood of releasing good-news forecasts and the magnitude of stock price increases. Additional evidence indicates that the good-news forecasts eventually conveyed by withholding firms after negative price shocks would likely have resulted in negative market reactions had they been released before the shocks. More generally, I provide evidence that managers withhold bad news and that exogenous stock price declines can induce its disclosure.     

Insider Trading and Voluntary Disclosures

We hypothesize that insiders strategically choose disclosure policies and the timing of their equity trades to maximize trading profits, subject to the litigation costs associated with disclosure and insider trading. Accounting for endogeneity between disclosures and trading, we find that when managers plan to purchase shares, they increase the number of bad news forecasts to reduce the purchase price. In addition, this relation is stronger for trades initiated by chief executive officers than for those initiated by other executives. Confirming this strategic behavior, we find that managers successfully time their trades around bad news forecasts, buying fewer shares beforehand and more afterwards. We do not find that managers adjust their forecasting activity when they are selling shares, consistent with higher litigation concerns associated with insider sales. Overall, our evidence suggests that insiders do exploit voluntary disclosure opportunities for personal gain, but only selectively, when litigation risk is sufficiently low.     

Are corporate managers savvy about their stock price? Evidence from insider trading after earnings announcements

We find that insiders trade as if they exploit market underreaction to earnings news, buying (selling) after good (bad) earnings announcements when the price reaction to the announcement is low (high). We also find that insider trades attributable to public information about earnings and the price reaction generate abnormal returns. By demonstrating that managers spot market underreaction to earnings news, our results imply that managers are savvy about their company’s stock price.     

Voluntary Disclosures,Corporate Control,and Investment

We examine the valuation and capital allocation roles of voluntary disclosure when managers have private information regarding the firm’s investment opportunities, but an efficient market for corporate control influences their investment decisions. For managers with long‐term stakes in the firm, the equilibrium disclosure region is two‐tailed: only extreme good news and extreme bad news is disclosed in equilibrium. Moreover, the market’s stock price and investment responses to bad news disclosures are stronger than the responses to good news disclosures, which is consistent with the empirical evidence. We also find that myopic managers are more likely to withhold bad news in good economic times when markets can independently assess expected investment returns.     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.     

Asymmetric effects of voluntary disclosure on stock liquidity: evidence from 8‐K filings

This paper examines whether the change in stock liquidity subsequent to voluntary disclosure is different between good news and bad news. Using voluntary 8‐K filings, we find that the increase in stock liquidity is more pronounced for firms with good news disclosure than for firms with bad news disclosure. In addition, such findings are stronger when a firm is less visible and when the short‐selling costs are high, suggesting that these two factors play an important role in increasing stock liquidity. Overall, this paper provides evidence that the tone of voluntary 8‐K news is an important determinant of stock liquidity.     

Do Managers Withhold Bad News?

In this study, we examine whether managers delay disclosure of bad news relative to good news. If managers accumulate and withhold bad news up to a certain threshold, but leak and immediately reveal good news to investors, then we expect the magnitude of the negative stock price reaction to bad news disclosures to be greater than the magnitude of the positive stock price reaction to good news disclosures. We present evidence consistent with this prediction. Our analysis suggests that management, on average , delays the release of bad news to investors.     

Major government customers and stock price crash risk

This paper studies whether government’s participation in product market, as a customer, affects supplier firms’ stock price crash risk. Using a sample of U.S. firms from 1980 to 2015, we find robust evidence that the presence of major government customers is associated with a lower level of stock price crash risk for supplier firms. Further, we show that government customers can lower suppliers’ crash risk by imposing monitoring activities on suppliers and/or reducing suppliers’ operational risk, leading to a reduction in supplier managers’ bad news hoarding behavior. Overall, our results indicate that government spending, as an important public policy, can significantly affect shareholders’ value by mitigating stock price crash risk.     

Accounting flexibility and managers’ forecast behavior prior to seasoned equity offerings

This study examines the effect of accounting flexibility on managers’ forecasting behavior prior to seasoned equity offerings (SEOs). Although SEO firms have a strong incentive to convey optimistic information to boost the pre-SEO stock price, they also face enhanced litigation risk arising from SEO-related regulations. Thus, I hypothesize that managers will release positive news through their forecasts (relative to the prevailing analyst consensus) prior to an SEO only if they have the accounting flexibility to manage subsequent reported earnings to meet or exceed their forecasts. I find that managers with greater accounting flexibility are more likely to issue a forecast prior to the SEO and that their forecasts are more likely to convey positive news and are more specific. Furthermore, I find no effect of accounting flexibility for non-SEO control firms or for non-SEO periods. My results suggest that when managers experience a tension between the incentive for voluntary disclosure and high litigation risk, accounting flexibility is an important factor that determines their forecasting behavior.     

Why Muddy the Water? Short selling and the disclosure of proprietary information

The conventional wisdom of voluntary disclosure literature is that the major factor preventing firms from disclosing customer-related information is firms' concern for proprietary costs. However, non-disclosure may also happen when firms have bad news to hide and are concerned about short sellers using customer information to verify bad news about the firms. By implementing a difference-in-differences research design against the backdrop of the deregulation of short selling in China, we find that increased short-selling pressure discourages firms from disclosing the identities of major customers. The findings also reveal consistent evidence supporting the bad news hoarding hypothesis rather than the proprietary cost hypothesis. Overall, our study provides an alternative explanation for firms’ lack of disclosure of customer information.     

Voluntary Disclosures and Analyst Feedback

We study the resource allocation role of voluntary disclosures when feedback from financial markets is potentially useful to managers in undertaking value maximizing actions. Managers weigh the short‐term price implications of disclosure against the long‐term efficiency gains due to feedback while financial analysts strategically produce information. The model can explain why managers disclose bad information (e.g., grim outlook), that reduces the stock price, and why prices respond more strongly to bad news relative to good news. We find that not all firms enjoy the same quality of feedback, and that feedback, by itself, does not induce more disclosure but less.     

Capital market consequences of managers' voluntary disclosure styles

This paper studies the capital market consequences of managers establishing an individual forecasting style. Using a manager-firm matched panel dataset, I examine whether and when manager-specific credibility matters. If managers' forecasting styles affect their perceived credibility, then the stock price reaction to forecast news should increase with managers' prior forecasting accuracy. Consistent with this prediction, I find that the stock price reaction to management forecast news is stronger when information uncertainty is high and when the manager has a history of issuing more accurate forecasts, indicating that individual managers benefit from establishing a personal disclosure reputation.     

Short-sale constraints and stock price crash risk: Causal evidence from a natural experiment

We examine the relation between short-sale constraints and stock price crash risk. To establish causality, we take advantage of a regulatory change from the Securities and Exchange Commission (SEC)’s Regulation SHO pilot program, which temporarily lifted short-sale constraints for randomly designated stocks. Using Regulation SHO as a natural experiment setting in which to apply a difference-in-differences research design, we find that the lifting of short-sale constraints leads to a significant decrease in stock price crash risk. We further investigate the possible underlying mechanisms through which short-sale constraints affect stock price crash risk. We provide evidence suggesting that lifting of short-sale constraints reduces crash risk by constraining managerial bad news hoarding and improving corporate investment efficiency. The results of our study shed new light on the cause of stock price crash risk as well as the roles that short sellers play in monitoring managerial disclosure strategies and real investment decisions.     

Short interest and stock price crash risk

Using a large sample of U.S. public firms, we find robust evidence that short interest is positively related to one-year ahead stock price crash risk. The evidence is consistent with the view that short sellers are able to detect bad news hoarding by managers. Additional findings show that the positive relation between short interest and future crash risk is more salient for firms with weak governance mechanisms, excessive risk-taking behavior, and high information asymmetry between managers and shareholders. Empirical support is provided showing that the relation between short interest and crash risk is driven by bad news hoarding.     

Detailed management earnings forecasts: do analysts listen?

We provide archival evidence on how a particular type of supplementary information affects the credibility of management earnings forecasts. Managers often provide detailed forecasts of specific income statement line items to shed light on how they plan to achieve their bottom-line earnings targets. We assess the effect of this forecast disaggregation on the credibility of management earnings forecasts. Based on a relatively large hand-collected sample of 900 management earnings forecasts, we find that disaggregation increases analysts’ sensitivity to the news in managers’ earnings guidance, suggesting that analysts find the guidance more credible. More importantly, we identify several factors that influence this relation. First, disaggregation plays a more important role when earnings are otherwise more difficult to forecast. Second, disaggregation is more important after Regulation Fair Disclosure prohibited selective disclosure, especially for firms that were more affected because they had previously provided more private guidance. Finally, in contrast to common assertions in the prior literature, we find that, in more recent years, disaggregation matters more for guidance that conveys bad news. Managers as well as researchers should be interested in evidence suggesting that financial analysts find disaggregation especially helpful in contexts where managers’ credibility is particularly important.     

Price Convexity and Skewness

This paper develops a model in which investors who are prohibited from short selling agree to disagree on the precision of a publicly observed signal. The model implies that the equilibrium price is a convex function of the public signal. The model predicts that (1) the stock price reacts more to good news than to bad news; (2) the skewness of stock returns is positively correlated with contemporaneous returns, but negatively correlated with lagged returns; (3) short sale constraints increase rather than decrease skewness; and (4) disagreement about information precision increases skewness. Empirical tests conducted find supportive evidence for all these predictions.     

Do Firms Strategically Internalize Disclosure Spillovers? Evidence from Cash-Financed M&As

We investigate whether managers internalize the spillover effects of their disclosure on the stock price of related firms and strategically alter their disclosure decisions when doing so is beneficial. Using data on firm-initiated disclosures during all-cash acquisitions, we find evidence consistent with acquirers strategically generating news that they expect will depress the target's stock price. Our results suggest the disclosure strategy leads to lower target returns during the negotiation period when the takeover price is being determined and results in a lower target premium. These findings are robust to a battery of specifications and falsification tests. Our results are consistent with expected spillovers influencing the timing and content of firms’ disclosures in M&A transactions.     

Litigating crashes? Insights from security class actions

Investors tend to litigate large stock price declines, i.e., file ‘stock-drop lawsuits’. However, it is less clear whether the ex-ante threat of security class actions can deter stock price crashes in the first place. To answer this question, we exploit the 1999 ruling of the Ninth Circuit Court of Appeals that discourages security class actions as a quasi-exogenous shock, and find that reducing the threat of security class actions leads to a significant increase in stock price crash risk measured by negative skewness of stock returns. We reveal that the main effect is partially driven by a reduction in the timeliness of bad news disclosure and worsened earnings quality, which is consistent with the view that bad news hoarding serves as the key factor in the formation of a stock price crash. Our overall findings highlight the importance of security class actions in deterring the occurrence of firm-level negative tail events on the financial market.     

企业业绩组合业绩差异与季报披露的时间选择--管理层信息披露的组合动机与信息操作

本文主要考察企业业绩组合、业绩差异与季报披露的时间选择之间的关系以及季报披露时间的信息内涵。实证研究显示,上年年报和一季度季报均为“好消息”,一季度每股收益、净资产收益率和主营业务利润率高的上市公司季报披露时间间隔大;上年年报为“好消息”而一季度季报为“坏消息”,上年年报为“坏消息”而一季度季报为“好消息”,上年年报和一季度季报均为“坏消息”,一季度每股收益比上年度高的上市公司季报披露时间间隔小。这可能是由于一季度季报和上年年报均要求在4月30日之前披露的特殊性,上市公司管理层在信息披露的过程中可能存在组合动机与信息操作行为,一季度季报披露的时间选择可能关键取决于上年年报和一季度季报披露的“好消息”或“坏消息”带来的积极影响或消极影响的组合与权衡。     

Earnings guidance and market uncertainty

We study the effect of disclosure on uncertainty by examining how management earnings forecasts affect stock market volatility. Using implied volatilities from exchange-traded options prices, we find that management earnings forecasts increase short-term volatility. This effect is attributable to forecasts that convey bad news, especially when firms release forecasts sporadically rather than on a routine basis. In the longer run, market uncertainty declines after earnings are announced, regardless of whether there is a preceding earnings forecast. This decline is mitigated when the firm issues a forecast that conveys negative news, implying that these forecasts are associated with increased uncertainty.
