BID-ASK SPREAD COMPONENTS AROUND ANTICIPATED ANNOUNCEMENTS

In this paper I re-examine spreads around dividend and earnings announcements and provide new evidence on patterns by examining the components of the bid-ask spread. Transaction data are examined through a recently developed spread decomposition model that decomposes the bid-ask spread into a fixed (execution) component and an adverse selection component. In addition, this model does not rely on a constant spread as previous spread decomposition models require. The results show that around earnings announcements, the bid-ask spreads and spread components have significant changes indicating that the anticipated announcement is informative. However, the actual public announcement of a dividend does not alter the bid-ask spread and spread components of actively traded securities.     

Information Asymmetry Around Earnings Announcements

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.     

AN INVESTIGATION OF THE EFFECT OF QUALIFIED AUDIT OPINIONS ON THE TRADING VOLUME AND BID-ASK SPREAD OF OVER-THE-COUNTER FIRMS

This paper investigates the information content of qualified audit opinions. The announcement of a qualified audit opinion is expected to cause investors' beliefs about the firm to converge. This increase in consensus would be evidenced by an unexpected decrease in trading volume surrounding the initial public announcement. Proportional bid-ask spread changes are used to test for changes in information asymmetry due to the announcement. After controlling for the effects of earnings announcements, a significant trading volume reaction is found in the week of the announcement for a sample of firms traded over the counter. No significant difference in proportional bid-ask spread is found. The results suggest that qualified audit opinions do, indeed, convey information to the investing public and this information results in homogeneous beliefs about the firm.     

Prior Information and the Market Reaction to Dividend Changes

We investigate two hypotheses regarding the information content of dividend change announcements. The first is that the importance of information signaled by a dividend change depends on the reliability of earnings forecasts existing before the dividend announcement. The second hypothesis is that the stock price reaction to dividend change announcements is related to earnings forecast error as of the time of the dividend announcement. Our results reveal that dividend increases convey more information for firms in which financial analysts least accurately predict earnings. The results also indicate that dividend increase and decrease announcements provide market participants with information which, on average, allows them to differentiate between firms on the basis of future earnings realizations. These differential information effects are shown to be robust to price, size, dividend yield, and overinvestment effects.     

The Information Content of Dividend Initiations and Firm Size: An Analysis Using Bid-Ask Spreads

The bid-ask spread of stock prices is examined for a sample of dividend initiating firms. The average percentage and dollar bid-ask spreads increase significantly on the day preceding the Wall Street Journal Index announcement date, possibly reflecting, on average, the market maker's anticipatory uncertainty. The day -1 increase in spread is inversely associated with firm size, an information environment proxy, after considering the simultaneous effects of dividend yield, returns variance, dollar trading volume and share price. The average percentage spread declines significantly on day 0 from its day -1 level and remains lower, on average, over a 365 day post-announcement period than 90 day pre-announcement levels. Similar results are obtained for dollar spread averages. The post-announcement percentage spread decline suggests a resolution of uncertainty, and is positively associated with the dividend yield. Dividend initiation announcements appear to reduce informational asymmetry.     

THE RELATION AMONG DIVIDEND POLICY,FIRM SIZE,AND THE INFORMATION CONTENT OF EARNINGS ANNOUNCEMENTS

In this paper we investigate the role of dividends in explaining the size effect. The previous literature concludes that before the firm's earnings announcement, small firm stock prices impound less information than large firm stock prices. This size effect is evidenced by the greater market reaction to small firm earnings announcements than to large firm earnings announcements. We find that if the dividend announcement precedes the earnings announcement, no size effect exists. The implication is that the information conveyed by dividend announcements includes the information conveyed to investors in large firms by other information sources. However, if the firm does not pay dividends or if the firm's earnings announcement precedes its dividend announcement, the size effect exists. The implication is that dividends do not completely explain the size effect. That is, there are information sources other than dividends that are exclusively available to investors in large firms, and the information provided by these sources is reflected in the stock price of large firms before the earnings announcement.     

Earnings Predictability, Information Asymmetry, and Market Liquidity

We investigate the relation between earnings predictability, information asymmetry and the behavior of the adverse selection cost component of the bid-ask spread around quarterly earnings announcements for NASDAQ firms. While we find an increase in the adverse selection component of the bid-ask spread on the day of and the day prior to quarterly earnings announcements for firms with less predictable earnings, we find no evidence of such changes for firms with more predictable earnings. During a non-announcement period, we find that firms with relatively less predictable earnings have consistently higher total bid-ask spreads than firms with more predictable earnings. This finding suggests that firms with relatively less predictable earnings have a higher cost of equity capital than comparable firms with more predictable earning streams, ceteris paribus. Hence, earnings predictability may be a legitimate concern of managers who wish to minimize their cost of equity capital at least as it pertains to bid-ask spreads.     

ADVERSE SELECTION,SPREAD BEHAVIOR,AND OVER-THE-COUNTER SEASONED EQUITY OFFERINGS

In this paper the effects of over-the-counter seasoned equity issuances on the percentage bid-ask spreads around announcement and offer dates are examined. A declining spread in the pre-announcement period suggests that resolution of information asymmetry begins well before the announcement date. Further, using issue size as a proxy for the extent of information asymmetry, we observe that spreads for larger issues reach “normal” levels before the first public disclosure of the offering. For smaller issues this occurs only on the offer date. Results are consistent with the dealer experiencing reduced adverse information risk as a result of information-gathering efforts during the underwriting process.     

Earnings Announcements and the Components of the Bid-Ask Spread

This study investigates the behavior of the components of the bid-ask spread around earnings announcements. We find that the adverse selection cost component significantly increases surrounding the announcements, while the inventory holding and order processing components significantly decline during the same periods. Our results suggest that the directional change in the total bid-ask spread depends on the relative magnitudes of the changes in these three components. Specifically, the decreases in inventory holding costs and order processing costs imply that earnings announcements may have an insignificant impact on the total bid-ask spread, even when they result in increased information asymmetry.     

The informativeness of pro forma and street earnings: an examination of information asymmetry around earnings announcements

Using adverse-selection cost as a proxy for information asymmetry, we find evidence that non-GAAP earnings numbers issued by management (pro forma earnings) and analysts (street earnings) improve price discovery. First, information asymmetry before an earnings announcement is positively associated with the probability of a non-GAAP earnings number at the forthcoming earnings announcement. Second, the post-announcement reduction in information asymmetry is greater when managers or analysts issue non-GAAP earnings at the earnings announcement and when the magnitude of the non-GAAP earnings adjustment is larger. Our results suggest that earnings adjustments by analysts and managers increase the amount and precision of earnings information and help to narrow information asymmetry between informed and uninformed traders following earnings announcements. Alternatively, the findings may be attributable to characteristics of non-GAAP firms and overall better reporting quality for those firms rather than non-GAAP earnings disclosure per se.     

The Changing Asymmetric Information Component of REIT Spreads: A Study of Anticipated Announcements

This study examines the risk-compensating behavior of REIT market makers. The bid-ask spread is hypothesized to compensate market makers for three costs: asymmetric information, order processing, and inventory. As the market makers perceived likelihood of transacting with a better-informed individual increases (decreases), the percentage of the spread that is attributed to asymmetric information will increase (decrease). This study examines the asymmetric information component of the bid-ask spread immediately prior to and following REIT dividend announcements and REIT funds from operations announcements during 1995 and 1996. The asymmetric information component increases the day before and then declines subsequent to dividend announcements of small and equity REITs. Asymmetric information costs increase following funds from operations announcements.     

Options and earnings announcements: an empirical study of volatility, trading volume, open interest and liquidity

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.     

DIVIDEND CHANGE ANNOUNCEMENT EFFECTS AND EARNINGS VOLATILITY AND TIMING

Recent modeling using the asymmetric information framework suggests that the magnitude of a market response to dividend change announcements should be related to the timing of the dividend announcement vis-a-vis the earnings release and to the stability of those earnings. The announcement effects of regular quarterly dividend changes are tested and these effects are related to the percentage change in the dividend yield, to the stability of the firm's earnings, to the timing of dividend and earnings announcements, and to the level of earnings compared with prior quarters. Analysis indicates that significant relationships exist between the announcement effect and changes in the dividend yield, and whether the dividend change is positive or negative. Only weak evidence exists that dividend announcement effects are larger when current earnings are unknown.     

Liquidity skewness in the London Stock Exchange

We study liquidity on the London Stock Exchange. We find that the average bid-ask spread declines, but that the skewness of the spread increases. These results are robust to firm size, trading volume and price level. Our findings hold when the bid-ask spread is estimated utilising high frequency data. We find that the bid-ask spread prior to earnings announcements dates is significantly higher than that of post earnings announcements, suggesting that asymmetric information has driven the increase in liquidity skewness. We also find that the effect of earnings announcements is more pronounced in the 2007 global financial crisis, consistent with the notion that extreme market downturns amplify asymmetric information. Our overall evidence also implies that increased competition and transparent trading environments limit market makers' abilities to cross-subsidize bid-ask spreads between periods of high and low levels of asymmetric information.     

Asymmetric Trading Costs Prior to Earnings Announcements: Implications for Price Discovery and Returns

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.     

Earnings Announcements, Asymmetric Information, Trades and Quotes

This paper empirically analyses trades and quotes around the times of 37 earnings announcements in the Paris Bourse. We find that trading volume is larger on announcement days, spreads are wider after announcements, and the permanent positive (resp. negative) price impact of purchases (sales) is greater around announcements. While the findings pertaining to the spread and the permanent impact of trades are consistent with the view that earnings announcements correspond to an increase in information asymmetries, the result that trading volume is larger suggests that other effects are at work.     

The intraday speed of adjustment of stock prices to earnings and dividend announcements

This paper examines the effects of Broad Tape news releases of earnings and dividend announcements on three aspects of intraday stock price behavior: mean returns, return variance, and serial correlation in consecutive price changes. The initial price reaction is evident in the first pair of price changes following the release (i.e., within a few minutes, at most). The returns earned by simple trading rules dissipate within five to ten minutes, although significant returns are detected in the overnight period and at the opening of trading on the next day. Disturbances in the variance and serial correlation persist for several hours and extend into the following trading day. As a class, dividend announcements induce much less activity than do earnings, although the response to dividend changes is comparable to the earnings announcement effect.     

Market Sidedness: Insights into Motives for Trade Initiation

We infer motives for trade initiation from market sidedness. We define trading as more two-sided (one-sided) if the correlation between the number of buyer- and seller-initiated trades increases (decreases), and assess changes in sidedness (relative to a control sample) around events that identify trade initiators. Consistent with asymmetric information, trading is more one-sided before merger news. Consistent with belief heterogeneity, trading is more two-sided before earnings and macro announcements with greater dispersion in analyst forecasts, and after news with larger announcement surprises. We examine the codeterminacy of sidedness, bid-ask spread, volatility, number of trades, and order imbalance.     

The Impact of Regulation Fair Disclosure on Information Asymmetry and Trading: An Intraday Analysis

This study examines the impact of Regulation Fair Disclosure (FD) on liquidity, information asymmetry, and institutional and retail investors trading behavior. Our main findings suggest three conclusions. First, Regulation FD has been effective in improving liquidity and in decreasing the level of information asymmetry. Second, retail trading activity increases dramatically after earnings announcements but there is a significant decline in institutional trading surrounding earnings announcements, particularly in the pre‐announcement period. Last, the decline in information asymmetry around earnings announcements is closely associated with a lower participation rate in the pre‐announcement period and more active trading of retail investors after earnings releases.     

Signaling, investment opportunities, and dividend announcements

This article examines potential explanations for the wealtheffects surrounding dividend change announcements. We find thatnew information concerning managers' investment policies isnot revealed at the time of the dividend announcement. We alsofind that dividend increases (decreases) are associated withsubsequent significant increases (decreases) in capital expendituresover the three years following the dividend change, and thatdividend change announcements are associated with revisionsin analysts' forecasts of current earnings. These results areconsistent with the cash flow signaling hypothesis rather thanthe free cash flow hypothesis as an explanation for the observedstock price reactions to dividend change announcements.
