In- and out-of-the-money convertible bond calls: Signaling or price pressure?

Convertible bond calls typically cause significant reactions in equity prices. The empirical research largely finds negative and positive announcement effects for the in-the-money and the out-of-the-money calls respectively. However, this research has difficulty distinguishing between the two main theoretical explanations: the signaling effect and the price pressure effect. In this paper, we differentiate between these two effects by using a unique data set of the in- and the out-of-the-money calls in the United States during the period of 1993 to 2007. We find that the announcement effect for the in-the-money call is predominantly explained by the subsequent order imbalances; and the stock market's reaction is spread over an entire trading day, which is consistent with the price pressure effect. In contrast, the announcement effect for the out-of-the-money call is driven by the size of the called convertible bond; and the stock market's reaction is almost immediate, which is consistent with the signaling effect.     

R&D Progress, stock price volatility, and post-announcement drift: An empirical investigation into biotech firms

I investigate the effects of R&D progress on the dynamics of stock price volatility and the post announcement drift to provide insights into whether or not and how capital markets react to corporate R&D progress in the context of the biotech industry. I find both stock price volatility and the post announcement drift decrease in R&D progress. More importantly, the decrease is proportional to the increase in the drug development success rate driven by R&D progress. Findings suggest that R&D progress conveys useful risk-relevant information, and plays an important role in explaining stock price volatility change and market anomalies.     

Earnings shocks,price responses,and short selling behavior

Existing researches usually study short sellers' behavior along a single dimension such as earnings news without considering the implications of multiple signals. In this paper, we investigate short selling behavior at earnings announcement period by using the shorting data from the Regulation SHO pilot program for the period January 2005 to July 2007. First, we document that, in about one third of our sample, earnings surprises and corresponding market price changes have opposite signs. By investigating how short sellers trade when earnings shocks and market price responses are of opposite signs, we find that there are more short selling activities when the market responds positively to negative earnings surprises; and that there are fewer short selling activities when the market responds negatively to positive earnings surprises. Overall, the shorting intensity at announcement period depends on both the earnings shock and price response signals.     

Macroeconomic announcements and price discovery in the foreign exchange market

This study shows that the dominance of the overlapping trading hours of London and New York in the price discovery of the EUR/USD and USD/JPY markets only applies on days with U.S. announcements. Different from Cai et al. (2008) and Wang and Yang (2011), we highlight the informational advantage of local traders at the arrival of macroeconomic announcements in the local market, and find that macroeconomic announcements affect the pattern of price discovery across different markets, consistent with Chen and Gau (2010) and Jiang et al. (2012). We also examine changes in information shares before and after the announcement. A significant increase in price discovery before the announcement suggests the possibility of information leakage, while enhanced price discovery efficacy after the announcement suggests that prices gradually adjust to new information, not just immediately respond to the arrival of announcements.     

Pre-bid price run-ups and insider trading activity: Evidence from Canadian acquisitions

A sample of 128 Canadian acquisitions from 1985 through 1995 is used to examine the relationship between pre-bid price run-ups in target shares and insider trading activity. We find that abnormal stock price performance at an early stage before the acquisition announcement is due to actual trading by corporate insiders. However, the run-up immediately preceding the takeover announcement appears due to market anticipation about an impending bid for the target. Furthermore, our results identify the stages in the acquisition process at which each effect occurs.     

Stock price effects and costs of secondary distributions

This study does not support the view that a large number of shares can be sold at the prevailing market price and at a small cost. A significant stock price decrease is observed at the initial announcement of secondary distributions. The price declines are greater for offerings by officers and directors and for larger offerings, but are significant for all types of sellers and for large and small offerings. There is no significant price decline at the offering when secondaries are announced in advance. Underwriting and other selling costs are substantial and are positively related to relative offering size.     

INDIVIDUAL,INSTITUTIONAL, AND SPECIALIST TRADE PATTERNS BEFORE AND AFTER DISCLOSURE

We examine the trade response of individuals, institutional traders, and specialists to disclosures. We investigate reactions to good versus bad news and mandatory versus discretionary announcements. We find that individuals and institutions both have heightened trade activity before disclosures. Institutional trade runs counter to the price reaction to upcoming discretionary disclosures. Institutions' post‐announcement trade is consistent with the direction of the price reaction to the announcement, whereas individuals' post‐announcement trade runs counter to the price reaction. Although specialists face increased trade pressure both before and after announcements, strong directional imbalances in specialist trade are not observed. JEL classification: G14     

Intraday stock price effects of ad hoc disclosures: the German case

This paper examines intraday stock price and trading volume effects caused by ad hoc disclosures in Germany. The evidence suggests that the stock prices react within 30 min after the ad hoc disclosures. The adjustment of the trading volume needs even more time. We find no evidence for abnormal high price nor trading volume reactions in the five transactions before ad hoc disclosures. The bigger the company, which announces an ad hoc disclosure, the less severe the abnormal price effect, following the announcement, is. The higher the trading volume at the last trading day before the announcement, the higher the price and trading volume effects, after the ad hoc disclosures, are.     

Delistings of secondary listings: price and volume effects

Despite their growing importance in recent years, delistings of secondary listings have received very little attention. This article investigates whether a delisting is accompanied by any price or volume effects on the company’s primary exchange. We apply a standard event study methodology to analyze these effects. The total sample consists of 255 companies that either delisted from the SIX Swiss Exchange, the Sponsored Segment of the SIX, Deutsche Börse, or the Tokyo Stock Exchange. The results show no significant price effects, either around the announcement or around the effective delisting. Furthermore, the results vary considerably between subsamples. Prices tend to decline around announcement; however, the effect is not permanent. The effective delisting is preceded by declining prices, whereas the event itself has no influence. Overall, this initial decline appears to be permanent. In general, volumes seem to rise around the announcement as well as around the date of the delisting.     

The Timing and Substance of Divestiture Announcements: Individual,Simultaneous and Cumulative Effects

This paper examines differences in announcement day effects among firms engaged in voluntary sell-offs. While, on average, an initial sell-off announcement results in a significant positive excess return, not all divestiture announcements are accompanied by positive price movements. Dividing the sample into two subsamples based on whether the transaction price is announced shows that the announcement day effect is significantly positive for the price group but not statistically different from zero for the no-price group. In addition, a positive relation is found between the relative size of the sell-off and the announcement day return.     

PRICE AND VOLUME EFFECTS ASSOCIATED WITH THE CREATION OF STANDARD & POOR'S MIDCAP INDEX

In this paper we explore price and volume effects associated with the 1991 creation of Standard & Poor's MidCap 400 index. Prior work on changes in the composition of existing indices finds a significant price response to the announcement. Various authors link the effect to price pressure, information, an outwardly shifting demand curve for securities, and the increased attention that comes with inclusion in an index. Using event study methodology, we find significant price and volume effects during the two weeks leading up to the Standard & Poor's announcement, but no significant effect in the two-day interval around the event. Apparently, information leakage and/or anticipation preceded the creation of the index. The price run-up is permanent since the positive abnormal returns leading up through the announcement are not associated with significantly negative abnormal returns after the announcement. In addition, MidCap stocks significantly outperform the market during the fifty-two weeks following the announcement. Using cross-sectional regressions, we show that these prior-period abnormal returns are positively related to abnormal volume and institutional holdings. We also find that firms trading over-the-counter had larger price run-ups than NYSE or AMEX firms.     

Stock price behavior surrounding stock repurchase announcements: Evidence from Japan

This paper examines stock price behavior surrounding announcements of stock repurchases made by Japanese firms from 1995 to 1998. Our analysis shows that, much as in the case of the U.S. markets, stock prices in Japan go up in response to stock repurchase announcements. We also find that there is no significant difference between the market reaction to the announcement for intention of repurchase execution and the market reaction to the announcement of an article alteration to allow stock repurchases. On the other hand, there is a significant difference in the pre-announcement period returns motivating these two announcements. While a large decline in stock price will motivate a firm to execute a stock repurchase, a smaller price decline will motivate a firm to merely alter its articles of association to allow future repurchases.     

SEASONED EQUITY OFFERINGS: THE CASE OF ALL-EQUITY FIRMS

Three theories have been widely proposed to explain the significant negative market response to the announcement of a new equity issue. By observing a similar negative effect in a sample of zero and near zero long-term debt firms, we are able to conclude that the capital structure hypothesis is not the sole explanation. Regressions of announcement period abnormal returns against subsequent cashflow change while controlling for price pressure effects provide evidence in support of the information hypothesis. Decomposition of the sample by issue purpose reveals a differential impact at the time of announcement consistent with an information-based explanation.     

Earnings management, lawsuits, and stock-for-stock acquirers’ market performance

There is a positive association between stock-for-stock acquirers’ pre-merger abnormal accruals and post-merger announcement lawsuits. The market only partially anticipates the effects of post-merger announcement lawsuits at the merger announcement and the post-merger announcement long-term market underperformance is largely limited to litigated acquisitions. Overall, the evidence suggests that it is important that investors not only undo the direct stock price effects of earnings management but also factor the contingent legal costs associated with earnings management.     

A Test for Price Pressure Effects in Tender Offer Stock Repurchases

The evidence in this paper supports the hypothesis that the previously documented stock price reversal following a tender offer announcement is consistent with a price pressure caused by a temporary shift in the security's demand curve. The authors came to this conclusion by redocumenting the price reversal, by finding an increase in trading volume around the tender offer announcement and expiration, by showing the increase in volume to be larger than expected from only an information effect, and by showing that short selling activity increases after the announcement and before the expiration of the tender offer.     

The S&P500 index effect reconsidered: Evidence from overnight and intraday stock price performance and volume

This study focuses on S&P500 inclusions and deletions, examining the impact of potential overnight price adjustment after the announcement of an S&P500 index change. We find evidence of a significant overnight price change that diminishes the returns available to speculators although there are still profits available from the first day after announcement until a few days after the actual event. More importantly, observing the tick-by-tick stock price performance and volume effects on the key days during the event window for the first time, we find evidence of consistent trading patterns during trading hours. A separate analysis of NASDAQ and NYSE listed stocks allows for a detailed examination of the price and volume effect at an intra-day level. We find that index funds appear to cluster their rebalancing activities near to and after the close on the event date, suggesting that they are more concerned with tracking error than profit.     

Anomalous security price behavior following management earnings forecasts

This study provides evidence that most of the stock price reactions to bad news management forecasts of annual earnings are reversed in the 60 days following the forecast. In addition, a significant amount of the price reaction to bad news forecasts of quarterly earnings is reversed in the market's reaction to the following quarterly earnings announcement. Unlike the previous overreaction evidence, this study is not subject to the criticisms of beta-shifts, cross-firm comparisons, or lengthy intertemporal comparisons. In addition, the results are robust to include many additional variables that could be hypothesized to affect the observed results.     

Security price reactions around corporate spin-off announcements

We examine security price reactions around the announcements of 123 voluntary spin-offs by 116 firms between 1963 and 1981 involving a pro-rata distribution of the common stock of a subsidiary to the stockholders of the parent firm. The median spin-off in the sample is 6.6% of the original equity value and is associated with an abnormal return of 7.0% from 50 days prior to the announcement through completion of the spin-off. No evidence is found to indicate the gains to stockholders represent wealth transfers from senior securityholders. Over the entire event period we find positive gains for firms engaging in spin-offs to facilitate mergers or to separate diverse operating units but negative returns to firms responding to legal and/or regulatory difficulties. In the two-day interval surrounding the first press announcement we find positive average excess returns for all groups.     

What Drives the S&P 500 Inclusion Effect? An Analytical Survey

We present an analytical survey of the explanations—price pressure, downward-sloping demand curves, improved liquidity, improved operating performance, and increased investor awareness—for the increase in stock value associated with inclusion in the S&P 500 Index. We find that increased investor awareness is the primary factor behind the cross-section of abnormal announcement returns. We also find some evidence of temporary price pressure around the inclusion date. We find no evidence that long-run downward-sloping demand curves for stocks, anticipated improvements in operating performance, or increased liquidity are related to the cross-section of announcement or inclusion returns.     

Stock reaction to dividend savings of convertible preferred calls: Free cash flow or price pressure effects?

Calls of in-the-money convertible preferred stock typically induce dividend savings for the firm, since preferred dividends exceed common stock dividends. Prior research finds that these savings are negatively related to stock returns at call announcement and argues that the market expects managers to abuse the increased free cash flow. This paper finds that dividend savings are closely related to call size, suggesting other explanations. Larger calls experience a more negative announcement reaction. Consistent with temporary liquidity effects, there is a price reversal during the conversion period, which is greater for larger calls.
