This study examines bid-ask spreads to determine how the anticipation and release of earnings announcements affect information asymmetry in the stock market. I use regression analysis and find that bid-ask spreads are negatively related to public information availability and positively related to earnings variability and the market reaction to prior unexpected earnings. The results suggest that firms for which earnings is expected to yield a relatively larger stock market reaction have greater information asymmetry than firms for which earnings are expected to yield a smaller market reaction.I also find that bid-ask spreads gradually increase in the four days prior to earnings announcements, and increase sharply the day prior to, the day of and the day after the earnings announcements. Bid-ask spreads seven to ten days after earnings announcements are not significantly different from bid-ask spreads seven to ten days prior to earnings announcements.  相似文献

This study is an empirical test of the Easley, O'Hara, and Srinivas (1998) multimarket sequential trade model of stock and option markets. We employ two approaches to determine the information content of signed stock and option trades executed around quarterly earnings announcements. The first approach expands the vector autoregression (VAR) technique of Hasbrouck (1991a) to include signed option trade volumes and inter‐trade durations. Estimates from the VAR models provide insight into whether both equity and option trades are viewed as informative by the equity specialist. The second approach focuses on the information content of the earnings releases to determine whether signed equity and option trades executed prior to the announcements are informed. Results indicate that although informed traders prefer to transact in both markets around earnings announcements, option market transactions contain no incremental information.  相似文献

Abstract:   We study the relationships between three variables which proxy for the ex‐ante level of information asymmetry – forecast dispersion, forecast revision volatility, and the level of analyst coverage, and equity bid‐ask spread and depth changes around quarterly earnings releases. Kim and Verrecchia (1994) suggest that earnings releases increase the level of information asymmetry and lower the level of liquidity in the security market. Using both an OLS regression framework and a simultaneous equations model, we examine whether equity bid‐ask spreads increase and depths decrease as the level of information asymmetry increases. Our results indicate that spreads are higher (relative to a non‐event period) around earnings announcements when information asymmetry is more pronounced; however, depths are lower only on the day following the announcement when there is greater information asymmetry. Relative spreads have a significant positive relation with both forecast dispersion and revision volatility and a significant negative relation with analyst coverage. Relative depths have a significant negative relation with forecast dispersion and a significant positive relation with analyst coverage. Our findings indicate that the equity specialist adjusts both spreads and depths when confronting informed traders around earnings releases and that these adjustments are more pronounced when the level of information asymmetry is greater.  相似文献

This study investigates the relationship between the dispersion of analysts' earnings forecasts and stock price variability around quarterly earnings announcements. Consistent with theoretical predictions, the empirical analysis shows that stock price variability at the time of earnings announcements is positively related to the degree of analysts' predisclosure earnings forecast dispersion. Additionally, firms with high levels of forecast dispersion exhibit significant increases in price variability for longer periods prior to and following earnings announcements than do firms with low levels of forecast dispersion. These results suggest that there is information about the earnings announcement that becomes available to at least a subset of investors prior to the earnings release and that market participants take different amounts of time to process the information conveyed by the earnings announcement.  相似文献

Abstract:  Using TORQ database we investigate the intra-day trading volume reactions to earnings announcements of five trader groups, individuals, institutions, exchange members, program traders, and specialists. The results of this study indicate that institutions are most active in the immediate aftermath of an announcement. Individual investors are slow at the beginning but accumulate heavy volume afterwards and exceed institutional trading volume. We find support for Harris and Raviv (1993) and Admati and Pfleiderer (1988) , who respectively argue that divergence of opinion about a public information and portfolio rebalancing cause surges in pre- and post-announcement trading volume. Further we find evidence of swift and aggressive trading by informed and sophisticated institutions in the immediate aftermath of the announcement, and delayed, aggressive trading volume 'overreaction' by 'slow' and 'overconfident' individual investors as documented by Barber and Odean (2000 and 2002) and Daniel et al. (1998) . NYSE specialists provide the bulk of the liquidity needs around earnings announcements.  相似文献

We examine market reactions to contemporaneous announcements of current earnings and future earnings guidance for evidence on how investors trade off relevance and reliability. Current earnings are more reliable than future earnings guidance, but future earnings guidance may be more relevant for predicting future performance. We find that current earnings are more strongly associated with announcement-period returns than concurrently disclosed future earnings guidance, consistent with investors’ relative preference for reliability. We find similar return reactions to stand-alone earnings and to earnings released with guidance. In contrast, return reactions are lower for guidance announced simultaneously with current earnings than for stand-alone guidance.  相似文献

This study investigates the effects of differences in predisclosure information asymmetry on trading volume reaction during quarterly earnings announcements. The analyses show that trading volume reaction to quarterly earnings announcements is positively related to the level of predisclosure information asymmetry and to the magnitude of the price reaction to the announcements. These results are consistent with Kim and Verrecchia's (1991a) theoretical trading volume proposition, and with Atiase and Bamber's (1994) tests of the proposition based on annual earnings announcements. This study also provides evidence on the relation of predisclosure information asymmetry and trading volume before and after quarterly earnings announcements.  相似文献

We examine (1) whether there is a shift in beta for individual securities around quarterly earnings announcements, and (2) whether these beta changes relate to certain characteristics of the firms. We find a statistically significant upward (downward) beta shift during the two-day earnings announcement period for 25 per cent (9 per cent) of a sample of 195 US firms. We also find that the beta shift at the time of the earnings announcement is significantly higher for small firms (i.e., more precise announcements).  相似文献

Abstract:

In this study, we investigate the trading behavior of institutional investors in China according to management earnings forecasts (MEFs) and earnings announcements (EAs). MEFs are mandatory under the stringent regulatory framework in China. We find evidence that both MEFs and EAs have an effect on the market. However, MEFs have a bigger effect on the market than do EAs. According to a sample of semiannual observations of firms from 2003 to 2008, we find that changes in the stock ownership of institutions are positively associated with EAs but not significantly associated with MEFs. When we further examine the relations between institutional characteristics and trading strategies, we find that growth funds exploit the arbitrage opportunity of MEFs.  相似文献

Abstract:   We investigate the effect of firm size on the market's short‐window response to annual earnings announcements for a large sample of Australian listed companies. Our research design involves regressions of unexpected earnings against unexpected returns. Non‐linearity in the returns‐earnings relationship is incorporated and other factors known to affect the response to earnings announcements are controlled for. Contrary to prior US research, our results show that firm size has either no effect on the response to earnings announcements (3 day window) or the response is significantly stronger for larger firms (twenty‐one day window). The information content of earnings announcements is present across firm size categories but the nature of the response differs with firm size and context.  相似文献

We show that the cost of trading on negative news, relative to positive news, increases before earnings announcements. Our evidence suggests that this asymmetry is due to financial intermediaries reducing their exposure to announcement risks by providing liquidity asymmetrically. This asymmetry creates a predictable upward bias in prices that increases preannouncement, and subsequently reverses, confounding short‐window announcement returns as measures of earnings news and risk premia. These findings provide an alternative explanation for asymmetric return reactions to firms' earnings news, and help explain puzzling prior evidence that announcement risk premia precede the actual announcements. Our study informs methods for research centering on earnings announcements and offers a possible explanation for patterns in returns around anticipated periods of heightened inventory risks, including alternative firm‐level, industry‐level, and macroeconomic information events.  相似文献

Insider Trading and Earnings Management   总被引:1,自引:0,他引:1  
Abstract:  This paper analyzes the relationship between earnings management and insider trading, specifically investigating whether discretionary accruals are related to insider trading and valuation. We find strong evidence of insiders managing earnings downward when buying and managing earnings upward when selling. On the marginal basis, value (high book-to-market value) firms manage their earnings upward compared to growth (low book-to-market value) firms, consistent with a signaling hypothesis. However, the opposite is true on the average basis, consistent with an opportunistic hypothesis.  相似文献

I test whether the anticipation of earnings news stimulates acquisition of customer information and mitigates returns to the customer–supplier anomaly documented by Cohen and Frazzini (“Economic Links and Predictable Returns.” The Journal of Finance 63 (2008): 1977–2011). I find that attention to a firm's publicly disclosed customers increases shortly before the firm announces earnings, and that customer stock returns predict supplier stock returns shortly before, but not after, the supplier's earnings announcement. I further find some evidence that these predictable returns are increasing in the level of customer information acquisition. These results are unique to anticipated disclosure events and suggest that anticipation of supplier earnings announcements resolves investor limited attention to customer information and accelerates price discovery of customer news.  相似文献

In this paper we study the impact of earnings announcements on implied volatility, trading volume, open interest and spreads in the stock options market. We find that implied volatility increases before announcement days and drops afterwards. Also option trading volume is higher around announcement days. During the days before the announcement open interest tends to increase, while it returns to regular levels afterwards. Changes in the quoted spread largely respond to higher trading volume and changes in implied volatility. The effective spread increases on the event day and on the first two days following the earnings announcement.  相似文献

This study examines trading in call and put options around quarterly earnings announcements and investigates whether the existence of these options affects the common stock trading volume response to these announcements. We find that the options trading volume reaction to earnings announcements is larger than the corresponding reaction in common stock. Consistent with the idea that options provide an alternative vehicle for trading on information, the existence of these options lowers the level of trading in common stock. Options also appear to offer investors an alternative method of taking short positions, as shown by the symmetric stock market trading volume reaction to good versus bad news for firms with listed options. In contrast, firms without listed options exhibit a larger trading volume response to good news than to bad news of similar magnitude.  相似文献

Abstract:   The China Securities Regulatory Commission requires all listed firms to make earnings announcements by the end of April each year. This requirement creates a unique opportunity for us to evaluate the timing of earnings announcements in a four‐month cluster. Firms, which are willing to make early announcements, tend to surprise the market, as indicated by the higher volume and price reactions. Later announcements are more predictable, as indicated by the lower volume and price reactions. These results indicate that an information asymmetry exists between early and late earnings announcements in Mainland China.  相似文献

Abstract:   This study focuses on non‐institutional trading behaviour around interim earnings announcements in the emerging market. We separate the stock trading activity of Finnish households into five trading classes and compare the results to institutional trading. Data covering the years 1996–2000 shows that earnings news triggers trading in every trading class. We also find some evidence that actively trading individuals especially (compared to passively trading ones) show increased buying and selling activity before the event compared to the non‐event period. After the event we find that Finnish households in the most active investor class tend to follow a contrarian strategy, especially selling after good news. This adds to previous evidence by Grinblatt and Keloharju (2000b) . Furthermore, the performance of the active investor classes is superior to that of passive ones. Finally, the institutional trading class is clearly less affected by the announcement than the active investor classes, suggesting that institutions utilize a broader information set than individual investors.  相似文献

We show that firms reporting sustained increases in both earnings and revenues have (1) higher quality earnings and (2) larger earnings response coefficients (ERCs) in comparison to firms reporting sustained increases in earnings alone. With respect to earnings quality, firms with revenue-supported increases in earnings have more persistent earnings, exhibit less susceptibility to earnings management, and have higher future operating performance. With respect to response coefficients, firms with revenue-supported increases in earnings have both higher ERCs and lower book value response coefficients, consistent with the implications of the Ohlson (1995, Contemporary Accounting Research 12, 661–687) model.JEL Classification: G12, M41  相似文献

This paper provides evidence of informed trading by individual investors around earnings announcements using a unique data set of NYSE stocks. We show that intense aggregate individual investor buying (selling) predicts large positive (negative) abnormal returns on and after earnings announcement dates. We decompose abnormal returns following the event into information and liquidity provision components, and show that about half of the returns can be attributed to private information. We also find that individuals trade in both return‐contrarian and news‐contrarian manners after earnings announcements. The latter behavior has the potential to slow the adjustment of prices to earnings news.  相似文献

盈余管理存在的根本原因在于投资者与管理层之间的信息不对称。业绩预告作为上市公司未来经营成果、财务状况与现金流量的预测,在很大程度上会影响投资者对上市公司的评估及其投资决策。从业绩预告披露的特征方面出发,研究业绩预告披露与盈余管理之间的关系,包括业绩预告的性质、预告精确度、预告误差分别与盈余管理程度的关系,结果发现:发布业绩预告的公司,盈余管理水平更高。预告精确度以及预告期间与预测当期盈余管理水平正相关,预测误差与盈余管理水平负相关。当消息类型不同的时候,预测的强制性与否以及"变脸"对盈余管理水平的影响不同。结论支持了上市公司财务报告迎合业绩预告披露的说法。  相似文献
