STOCK REPURCHASES AND SECURITYHOLDER RETURNS: A CASE STUDY OF TELEDYNE

This study examines securityholder returns around nine major repurchase announcements and 10 other repurchase-related announcements by the Teledyne Corporation between 1972 and 1984. Statistically significant positive excess returns to common stock and convertible preferred stockholders are documented. Contrary to prior research that investigated the average response to repurchase announcements, however, there is a wealth transfer from bondholders to stockholders. Bondholder returns around the repurchase announcements are significantly negative. These returns are examined for each announcement and each bond issue.     

The effects of legal regime on the patterns of stock returns surrounding ADR earnings announcements

This study examines the effects of legal regime on the patterns of stock returns surrounding the earnings announcements of American Depositary Receipt (ADR) programs. My results indicate that the properties of accounting earnings associated with the local legal regime of an ADR program spill over to U.S. GAAP reconciled earnings. In particular, I find that the market reacts significantly to the earnings announcements of the ADR programs from common law countries whose accounting earnings are known to be more conservative and timely, but not to those of the ADR programs from code law countries where the earnings are known to be less conservative and timely.     

INSIDER TRADING EFFECTS ON STOCK RETURNS AROUND OPEN-MARKET STOCK REPURCHASE ANNOUNCEMENTS: AN EMPIRICAL STUDY

In this paper we empirically examine the effects of insider trading activities, the percentage of common shares outstanding authorized for repurchase, and management ownership on stock returns around open-market stock repurchase announcements. The study is conducted on a sample of 204 firms that announced open-market stock repurchases between 1982 and 1990. Results show that insider trading activities during the month that immediately precedes the announcement have a significant effect. While stockholders of firms with insider net selling activities earn positive excess returns, those of firms with insider net buying activities earn larger and more significant excess returns. Insider trading activities during more distant periods do not show any effects on stock returns. Results also indicate that management ownership has a significant positive effect on stock returns, and this effect is more positive when the percentage of common shares outstanding authorized for repurchase is large.     

The Relative Signalling Power of Dutch-Auction and Fixed-Price Self-Tender Offers and Open-Market Share Repurchases

We compare three forms of common stock repurchases. Dutch-auction self-tender offers and open-market share repurchase programs are weaker signals of stock undervaluation than fixed-price self-tender offers. The price increase from buyback announcements is greater when insider wealth is at risk, greater following negative net-of-market stock returns, and unrelated to prior market returns. Buyback announcement returns are also increasing in the fraction of shares sought, which is consistent with both signalling and an upward-sloping supply curve for stock.     

The effects of capital structure change on security prices: A study of exchange offers

This study considers the impact of capital structure change announcements on security prices. Statistically significant price adjustments in firms' common stock, preferred stock and debt related to these announcements are documented and alternative causes for these price changes are examined. The evidence is consistent with both corporate tax and wealth redistribution effects. There is also evidence that firms make decisions which do not maximize stockholder wealth. In addition, a new approach to testing the significance of public announcements on security returns is presented.     

Improving corporate governance where the State is the controlling block holder: evidence from China

This paper examines changes in values and returns for Chinese firms around announcements of block-share transfers among government agencies, State-owned enterprises and private investors. We find that transfers to all three types of investors result in positive abnormal returns around transfer announcements, even when the transfers do not create a new controlling block holder and when transfers are between State entities. We also find that transfers from State entities to private entities result in larger increases in value and returns than transfers between State-controlled entities – consistent with the superior incentives and expertise of private investors. We conclude that corporate governance can be improved at State-controlled firms by improving incentives and expertise of controlling block holders.     

STOCK DIVIDENDS AS SIGNALS

This study analyzes stock dividends as signals from managers. It is argued that in the presence of information asymmetries between managers and investors, stock dividends provide a relatively inexpensive and unambiguous signalling device. Based on an examination of the daily returns around 317 stock dividend announcements, it is concluded that these announcements are interpreted by investors as signals from managers. Further analysis also indicates that stock dividend size is positively related to announcement day returns.     

Market behaviour around bankruptcy announcements: evidence from the Australian Stock Exchange

The corporate distress literature to date has largely focused on the predictive power of accounting variables ( Altman, 2001 ). Following previous literature, this study examines the relevance of abnormal stock returns in discriminating between failed and non‐failed firms (e.g. Clark and Weinstein, 1983; Shumway, 2001). Our results confirm the findings of previous literature that investors in failed firms typically incur substantial negative stock returns leading up to failure announcements. However, in contrast to prior research we do not find evidence of an announcement effect (i.e. negative stock returns on the event day itself or the day preceding). We also document evidence that the bid‐ask spreads of failed firms widen substantially up to 7 months prior to failure, indicating the likelihood of significant information asymmetries across investors in failed firms.     

The valuation effects of stock splits and stock dividends

This study presents evidence which indicates that stock prices, on average, react positively to stock dividend and stock split announcements that are uncontaminated by other contemporaneous firm-specific announcements. In addition, it documents significantly positive excess returns on and around the ex-dates of stock dividends and splits. Both announcement and ex-date returns were found to be larger for stock dividends than for stock splits. While the announcement returns cannot be explained by forecasts of imminent increases in cash dividends, the paper offers several signalling based explanations for them. These are consistent with a cross-sectional analysis of the announcement period returns.     

Earnings Announcements,Differences of Opinion and Management Guidance

Berkman, Dimitrov, Jain, Koch, and Tice (2009) document a negative relationship between differences of opinion and earnings announcement returns, and this relationship is more pronounced when short‐sale constraints are likely to be high. These findings are interpreted as support for the theory in Miller (1977) that binding short sale constraints cause pessimists to be underrepresented in price formation. We conjecture that accounting information (i.e., earnings news) is likely to play a role in this returns pattern. After controlling for the level of earnings news, we find that the relationship between differences of opinion and stock returns is either eliminated or opposite from what is predicted by Miller's theory. Further, we present evidence that suggests the confounding effect of earnings news can be explained by (pessimistic) management earnings guidance. Our findings offer an alternative explanation for why low differences of opinion stocks earn greater abnormal returns around earnings announcements.     

Common Stock Offerings and Earnings Expectations: A Test of the Release of Unfavorable Information

This paper examines the revisions of analysts' forecasts of future earnings around announcements of common stock offerings. The forecasts of the current year earnings are, on average, decreased when firms announce plans to issue additional common stock. The size of the decrease is significantly related to announcement period abnormal stock returns. In contrast, forecasts of the five-year growth rate of earnings are, on average, unchanged. We interpret these results as being consistent with the claim that equity offering announcements convey unfavorable information regarding the firm's short-term but not its long-term earnings prospects.     

UNLISTED TRADING PRIVILEGES,LIQUIDITY, AND STOCK RETURNS

In this study we examine the effect of dual trading through unlisted trading privileges (UTPs) on liquidity and stock returns. Stocks with UTPs trade in a different market structure than stocks listed and traded only on the AMEX and NYSE. Differences in market structure may affect stock returns through liquidity services provided by the competing markets. The sample comprises 852 AMEX and NYSE firms that began unlisted trading on the Philadelphia, Pacific, Midwest, or Cincinnati exchanges between 1984 and 1988. The results show significantly positive abnormal returns around the SEC's announcement of a regional exchange's filing for UTPs. The results also suggest that increased competition improves trading liquidity. Only stocks with low liquidity before UTPs announcements experience significantly improved liquidity and positive stock returns.     

VALUATION EFFECT OF ISSUING NONSUBORDINATED VERSUS SUBORDINATED DEBT

Recent studies analyzing stock market reaction to announcements of straight debt offerings report, in general, insignificant abnormal stock returns. In this study we examine the effect of debt seniority on market reaction. The evidence shows weakly positive abnormal returns upon the announcements of nonsubordinated straight debt offerings. In contrast, announcements of subordinated straight debt offerings induce significantly negative abnormal returns. Our findings generally support the information release hypothesis.     

How important are semi-annual earnings announcements? An information event perspective

Using a method that avoids the need to specify earnings expectations, we demonstrate that the period surrounding the semi-annual announcement of Australian firms' earnings is, on average, an important source of information. Although there is substantial year-to-year variation, we observe no evidence of any significant time trend, and also conclude that a shift from Australian domestic generally accepted accounting principle to International Financial Reporting Standards did not impact the association between earnings announcement windows and stock returns. We also find no evidence that the informativeness of earnings announcements varies systematically with firm size, analyst following or economic news (i.e., positive vs. negative stock returns, profits vs. losses), although we do observe significant variation across industries. Our conclusion is further supported by contrasting the earnings release date with the days immediately prior to release, or high information days other than earnings announcement windows. Using a more precise event window relative to prior studies (i.e., 3 h vs. 3 days), we confirm that earnings announcements contain significant new information about fundamentals.     

Informed Options Trading Prior to Dividend Change Announcements

This paper investigates the information content of options trading prior to dividend change announcements. I find a positive (negative) relation between pre‐announcement abnormal implied volatility (IV) spread (abnormal IV skew) and cumulative abnormal stock returns around dividend change announcements. The predictive power of informed options trading is stronger for announcements of dividend reduction and when the options market is more liquid relative to the stock market and weaker when information has already been incorporated in the stock market. The predictability of informed options trading is robust to a placebo test and alternative measures of informed options trading. Overall results suggest that informed options trading predicts dividend change announcement returns.     

The CDS market reaction to restatement announcements

I investigate the credit market's reaction to restatement announcements through changes in credit default swap (CDS) spreads. I document an overall positive association between CDS returns and restatement announcements. Specifically, I find that more positive CDS returns are associated with restatements (1) involving fraud and (2) affecting more accounts. Moreover, these reactions are sensitive to the underlying entities’ credit ratings and the market‐wide investor sentiment. Next, I compare CDS and stock market reactions and find that more negative stock returns are associated with restatements (1) involving fraud and (2) decreasing reported income.     

The effect of monetary policy shocks on stock prices accounting for endogeneity and omitted variable biases

A new high frequency data set is used to estimate the impact of the Fed on the level and volatility of stock prices while accounting for endogeneity and omitted variable biases and potential asymmetries. Results show that after addressing these issues, the effect of policy shocks on the level and volatility of stock returns is higher than previously reported. GARCH findings indicate that the volatility impact is tent-shaped, spiking during policy announcements and declining before and after the release. The level and conditional volatility of stock returns is found to respond asymmetrically to the type of policy shocks (timing versus future path of monetary policy) and the type of policy action (easing versus tightening).     

Managerial succession and firm performance

We examine CEO turnover and firm financial performance. Accounting measures of performance relative to other firms deteriorate prior to CEO turnover and improve thereafter. The degree of improvement is positively related to the level of institutional shareholdings, the presence of an outsider-dominated board, and the appointment of an outsider (rather than an insider) CEO. Turnover announcements are associated with significantly positive average abnormal stock returns, which are in turn significantly positively related to subsequent changes in accounting measures of performance. This suggests that investors view turnover announcements as good news presaging performance improvements.     

DEBT REFUNDING AND SHAREHOLDER WEALTH: THE PRICE EFFECTS OF DEBT-FOR-DEBT EXCHANGE OFFER ANNOUNCEMENTS

This study examines the impact of debt refunding on common stock prices for a sample of 48 exchange offers announced from 1970 through 1981. Exchange offer announcements do not have a significant impact on average common stock returns but appear to produce idiosyncratic share price effects. Refunding-induced price effects were unrelated to several exchange offer characteristics including tax shield increases, exchange offer premia, and transaction costs of refunding. Common stock excess returns were negatively related to reductions in debt service payments and relaxation of dividend payment constraints. Thus, the evidence is consistent with theories predicting that certain debt refundings generate negative information-signaling price effects.     

The Intra-Industry Transfer of Information Inferred from Announcements of Corporate Security Offerings

This study investigates the extent to which information inferred by investors from initial announcements of corporate security offerings affects share prices in the capital markets. The empirical tests measure the response in the common stock prices of both firms announcing a security offering and non-announcing firms operating in the same industry. Small but significantly negative abnormal returns are shown by industry shares upon initial announcements of common stock, convertible debt, and straight debt public offerings. Such an industry response indicates that share prices incorporate an inside assessment of factors relevant to the valuation of an industry subset of firms.
