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.     

Implied Standard Deviations and Post-earnings Announcement Volatility

This paper investigates volatility increases following annual earnings announcements. Standard deviations implied by options prices are used to show that announcements of bad news result in a lower volatility increase than those of good news, and delay the increase by a day. Reports that are difficult to interpret also delay the volatility increase. This delay is incremental to that caused by reporting bad news, although the effect of bad news on slowing down the reaction time is dominant. It is argued that the delays reflect market uncertainty about the implications of the news.     

Internal control effectiveness,textual risk disclosure,and their usefulness: U.S. evidence

This paper investigates the impact of internal control effectiveness (ICE) on the level of textual risk disclosure (TRD; including aggregate risk disclosure and its tone of good news and bad news about risk). Our findings suggest that firms with an ineffective internal control system exhibit significantly lower levels of TRD than firms with effective internal controls. Besides, we show a significant change in TRD behavior provided by managers of firms with recurrent ineffective internal controls. Pursuant to agency theory, this behavior change is prompted to reduce the expected public uncertainty and agency problems. We also investigate the usefulness of ICE reporting and TRD to the market. Results suggest that firms reporting ineffective internal controls are likely to have higher investor-perceived risk than firms reporting effective internal controls. Furthermore, TRD improves firms' market liquidity, and such improvement is principally driven by good news rather than bad news about risk. Collectively, our results fill an apparent gap in the literature on the importance of ICE, as well as the usefulness of the external auditor's attestation on a firm's internal controls and management TRD.     

Can “Big Bath” and Earnings Smoothing Co‐exist as Equilibrium Financial Reporting Strategies?

We study a model of financial reporting where investors infer the precision of reported earnings. Reporting a larger earnings surprise reduces the inferred earnings precision, dampening the impact on firm value of reporting higher earnings, and providing a natural demand for smoother earnings. We show that for sufficiently "bad" news, the manager under-reports earnings by the maximum, preferring to take a "big bath" in the current period in order to report higher future earnings. If the news is "good," the manager smoothes earnings, with the amount of smoothing depending on the level of cashflows observed. He either over-reports or partially under-reports for slightly good news, and gradually increases his under-reporting as the news gets better, until he is under-reporting the maximum amount for sufficiently good news. This result holds both when investors are "naïve" and ignore management's ability to manipulate earnings, or "sophisticated" and correctly infer management's disclosure strategy.     

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.     

CEO incentive compensation and stock price momentum

We document strong evidence that CEO incentive compensation can predict the significance of stock price momentum through discretionary accrual and real activities manipulation. The profit of momentum strategy increases with CEO pay-for-performance incentive, but decreases with CEO risk-taking incentive. It also evaluates the effects of information uncertainty on such relationship. The evidence is more significant for firms with older and longer tenured CEOs and firms with more informed traders. The relationship between the profit of momentum strategy and CEO pay-for-performance incentive is stronger among CEOs without the risk-taking incentive. Our results are robust for different sub-samples based on before and after Reg FD and Sarbanes–Oxley Act, even after controlling for the potential endogeneity. Further, our findings are consistent with the information diffusion explanation of momentum and the agency theory that incentivised CEOs tend to manipulate information by smoothing good news, concealing mildly bad news and accelerating the disclosure of extremely bad news.     

The options market response to accounting earnings announcements

We examine the reaction of the equity options market to accounting earnings announcements over the period 1996–2008 using changes in implied volatility to measure the options market response to earnings news. We find that positive earnings surprises and positive profit announcements produce a larger uncertainty resolution than negative earnings surprises and loss announcements. We demonstrate an inverse relation between the change in implied volatility and earnings news in a three-day window immediately after an earnings announcement. We refer to the magnitude of this relation as the ‘options market earnings response coefficient’. This ‘options market earnings response coefficient’ is stronger for both bad news announcements and positive profit announcements. We do not find any significant relation between changes in implied volatility and earnings news in the pre- or post-announcement periods. We conclude that the options market efficiently absorbs earnings information.     

Volatility transmission in global financial markets

This paper considers the transmission of volatility in global foreign exchange, equity and bond markets. Using a multivariate GARCH framework which includes measures of realised volatility as explanatory variables, significant volatility and news spillovers are found to occur on the same trading day between Japan, Europe, and the United States. All markets exhibit significant degrees of asymmetry in terms of the transmission of volatility associated with good and bad news. There are also strong links between diffusive volatilities in all three markets, whereas jump activity is only important within the equity markets. The results of this paper deepen our understanding of how news and volatility are propagated through global financial markets.     

Short Selling Pressure,Stock Price Behavior,and Management Forecast Precision: Evidence from a Natural Experiment

Using a natural experiment (Regulation SHO), we show that short selling pressure and consequent stock price behavior have a causal effect on managers’ voluntary disclosure choices. Specifically, we find that managers respond to a positive exogenous shock to short selling pressure and price sensitivity to bad news by reducing the precision of bad news forecasts. This finding on management forecasts appears to be generalizable to other corporate disclosures. In particular, we find that, in response to increased short selling pressure, managers also reduce the readability (or increase the fuzziness) of bad news annual reports. Overall, our results suggest that maintaining the current level of stock prices is an important consideration in managers’ strategic disclosure decisions.     

Large shareholders and disclosure strategies: Evidence from IPO lockup expirations

We examine the effect of large shareholders? ex ante selling incentives on firms? voluntary disclosure choices in the setting of IPO lockup expirations. We find evidence that managers delay disclosures of bad news, not for their own benefit, but to enable influential pre-IPO shareholders to sell their shares at more favorable prices. Delays are more pronounced when aggregate selling incentives are greater, when uncertainty is high, and when venture capitalists, influential investors with strong selling incentives, own more shares. Simultaneously, managers? disclosure decisions reflect litigation concerns; no significant delays occur when litigation risk is high or when managers trade themselves.     

Impact of earnings performance on price‐sensitive disclosures under the Australian continuous disclosure regime

This study examines the relation between accounting earnings and the frequency of price‐sensitive corporate disclosure under Australia's statutory continuous disclosure requirements. Despite low litigation threats and excepting loss‐making firms, results show that firms with earnings declines (bad news) are more likely to make continuous disclosure than firms with earnings increases (good news). This suggests that market forces and regulators’ scrutiny are sufficient to induce a ‘bad news’ disclosure bias. This study also examines the ‘materiality’ requirement under the continuous disclosure requirements and finds a positive relation between disclosure frequency and the magnitude of earnings news. The earnings–return correlation is positively associated with disclosure frequency for the financial services industry.     

Modeling the Conditional Covariance Between Stock and Bond Returns: A Multivariate GARCH Approach

To analyze the intertemporal interaction between the stock andbond market returns, we assume that the conditional covariancematrix follows a multivariate GARCH process. We allow for asymmetriceffects in conditional variances and covariances. Using dailydata, we find strong evidence of conditional heteroskedasticityin the covariance between stock and bond market returns. Theresults indicate that not only variances, but also covariancesrespond asymmetrically to return shocks. Bad news in the stockand bond market is typically followed by a higher conditionalcovariance than good news. Cross asymmetries, that is, asymmetriesfollowed from shocks of opposite signs, appear to be importantas well. Covariances between stock and bond returns tend tobe relatively low after bad news in the stock market and goodnews in the bond market. A financial application of our modelshows that optimal portfolio shares can be substantially affectedby asymmetries in covariances. Moreover, our results show sizablegains due to asymmetric volatility timing.     

高管持股、择时披露与市场反应

基于2001至2008年间A股公司业绩预告的样本,本文研究了高管持股对择时信息披露策略的影响,以及市场对择时披露信息的反应。研究发现,A股公司在业绩预告时存在择时披露的行为:好消息①更倾向于在交易日披露,坏消息更倾向于在休息日披露。高管持股比例会显著影响择时披露策略:高管持股比例越高的公司,进行择时披露的可能性也越高。从市场反应角度看,休息日披露的坏消息与交易日披露的坏消息没有显著差异,休息日披露的好消息反而会产生更加显著的正面市场反应。本文的研究意味着,高管持股比例会显著提高上市公司进行择时信息披露的可能性,但是市场在一定程度上能够识别择时披露策略,本文的研究结果支持了"信息消化"假说。     

The debt market relevance of management earnings forecasts: evidence from before and during the credit crisis

We investigate the credit market’s response via changes in credit default swap (CDS) spreads to management earnings forecasts and evaluate the importance of these forecasts relative to earnings news during the periods before and during the recent credit crisis. We document that credit markets react significantly to management forecast news and that the reactions to forecast news are stronger than to actual earnings news. Consistent with the asymmetric payoffs to debt holders, the forecast news is mainly relevant for firms with poor credit rating or announcing bad news. We also show that the relevance of management forecasts to credit markets is particularly strong during periods of high uncertainty, as experienced during the recent credit crisis.     

Does alternative data reduce stock price crash risk? Evidence from third-party online sales disclosure in China

This study empirically investigates the effect of releasing alternative data on firm-specific price crash risk. Using the public launch of a firm's third-party online sales data in a well-known Chinese financial database as an exogenous shock, we find that stock price crash risk significantly decreases with the disclosure of third-party online sales data. The results are robust to a series of endogeneity corrections and robustness checks. We also find that the reduction of stock price crash risk is due to the decrease in managers' bad news withholdings and the increase in the accuracy of market expectations. In addition, the negative association between third-party online sales disclosure and crash risk is more pronounced for firms with weaker external governance, higher earnings volatility, greater likelihood of sales manipulation, and lower book-to-market ratio. Our findings yield important implications for a comprehensive understanding of the information disclosure effect of online sales data in the capital market and the mechanisms to reduce stock price crash risk.     

Voluntary disclosure and the cost of equity capital: Evidence from management earnings forecasts

This paper examines the directional effects of management earnings forecasts on the cost of equity capital. We find that forecasters of bad news experience a significant increase in the cost of equity capital in the month after their disclosure. Conversely, the cost of equity capital for good news forecasters does not change significantly in the same period. We also indicate that the magnitude of changes in the cost of capital for good news forecasters is significantly lower than that for bad news forecasters and non-forecasters, which suggests that investors may view good news forecasts less credible. Finally, we show that the effect of the subsequent earnings announcement on the cost of equity capital is preempted by the management forecasts for bad news firms, and that the combined effects of the management earnings forecasts and the earnings announcement are not significant for both good news and bad news forecasters. Our paper contributes to the literature by adding evidence on directional effects of voluntary disclosures and on long-term economic consequences of management earnings forecasts.     

Labor Unemployment Concern and Corporate Discretionary Disclosure

We investigate how firms strategically vary their disclosure policies in response to labor unemployment concern. Using changes in state unemployment insurance laws as exogenous variations of labor unemployment concern, we show that firms provide more bad news forecasts when unemployment concern is low. This relation is stronger when firms are financially constrained, when CEOs and CFOs have higher equity incentives, and when workers are likely to be affected more by unemployment. Our findings are not driven by earnings management reversal or underlying performance changes, and are robust to a battery of identification tests. Finally, we find a similar effect of unemployment concern on disclosure using the tone of 10‐K and 10‐Q filings as an alternative proxy for corporate disclosure. Overall, our findings suggest that labor unemployment concern is an important consideration for corporate discretionary disclosure.     

How do investors react under uncertainty?

It has long been accepted that risk plays an important role in determining valuation where risk reflects that investors are unsure of future returns but are able to express their prior expectations by a probability distribution of these returns. Knight (1921) introduced the concept of uncertainty where investors possess incomplete knowledge about this distribution and so are unable to formulate priors over all possible outcomes. One common approach for making uncertainty tractable is to assume that investors faced with uncertainty will base their decisions on the worst case scenario (i.e. follow maxmin expected utility). As a consequence it is postulated that investors will become more pessimistic as uncertainty increases, upgrading bad news and downgrading good news. Using Australian data, we find evidence that investors react to bad news at times of high market uncertainty but largely ignore good news which is consistent with them taking on a pessimistic bias. However, we also find evidence of the reverse when market uncertainty is low with investors taking on an optimistic stance by ignoring bad news but reacting to good news. We also find that the impact that market uncertainty has on the reaction of investors to new information is modified by the prevailing market sentiment at the time of the announcement. Besides throwing light on the question of how uncertainty impacts on investor behaviour, our findings seriously challenge the common assumption made that investors consistently deal with uncertainty by applying maxmin expected utility.     

Short selling constraints and politically motivated negative information suppression

This study examines the effect of short selling constraints on politically motivated suppression of negative information. We use a unique setting in China, in which there are multiple exogenous changes in short selling constraints and firms have strong incentives to suppress negative information during politically sensitive periods. Results from Difference-in-Differences analyses and a regression discontinuity design show that removing short selling constraints can reduce politically motivated bad news suppression. Short selling can reduce negative information suppression through the channels of improved financial reporting quality, more voluntary disclosure from management, and more timely release of information by media. In addition, the effect of short selling on reducing bad news hoarding is more pronounced for more politically sensitive meetings and for state-owned firms located in regions with weaker market and institutional development.     

Volatility changes in European currency exchange rates due to EMS announcements

This study examines the effects of announcements concerning European Monetary Union on the exchange rate volatilities of several European currencies. It is expected that when good news is portrayed in regard to a single currency this will be considered bad news, thus eliciting a negative reaction, for the German mark. Conversely, good news for a single currency should also be good news for weaker currencies, such as the Portuguese escudo, the Italian lira, the Greek drachma, and the Spanish peseta. In terms of volatility, a reaction to good news should be a reduction in volatility, as bad news should cause an increase in volatility. In total there are 22 announcements examined from January 1986 through September 1997. The German mark is observed to experience greater increases in volatility than decreases, as does the Italian lira. Portugal and Greece appear to react more strongly to positive news in that the decreases in volatility are on average greater than the increases.
