The liquidity and trading activity effects of acquisition payment methods: Evidence from the announcements of private firms' acquisitions

We investigate how the liquidity and trading activity effects of the announcement of the acquisition of private targets vary by payment method. We find significant increases in trading activity around acquisition announcement dates irrespective of the payment method used; however, fluctuations are lower for acquisitions financed by earnouts and cash. Similarly, the stocks of acquirers using cash and earnouts are also less affected by a general loss of liquidity that accompanies announcements. We show that these effects are explained by the interpretation of cash acquisition by the market as an option used when acquirers perceive no risk of being adversely selected, and the potential of earnout as an adverse selection risk reduction tool.     

Strategic insider trading around earnings announcements in Australia

This paper tests, within the Australian setting, whether directors strategically time trades in their own firms, around earnings announcements, in the context of impediments to trading in the immediately preceding period. I show that both signed and unsigned trade activity are insignificantly different from zero in the preceding period, and significantly negative and positive after the event. Further, directors in Australia significantly sell following positive earnings news, and buy after negative news, providing evidence of ‘indirect’ trading. Directors’ trades in the longer-term pre-announcement period are also negatively related to the news content sentiment, contrary to expectation. Finally, I find evidence of positive autocorrelation between directors’ trades over the longer-term past, and those executed after earnings announcements, which, in the absence of the ‘short-swing’ rule in Australia, casts doubt over short-term strategic insider trading, more generally.     

Is there information content from insider trading activities preceding earnings and dividend announcements in Hong Kong?

This study examines whether insiders (directors) exploit information advantage of their firms by trading stocks before the simultaneous earnings and dividend announcements in Hong Kong. Our findings show that there are significant net-insider-buying activities before the announcements of good news ('Earnings-Dividend Increase') and significant net-insider-selling activities before bad news ('Earnings-Dividend Decrease' and 'Earnings Decrease-Dividend Zero'). In addition, our regression results provide some support for the hypothesis that there is a predictive relation between pre-event insider trading activity and the abnormal return of the announcements.     

The information content of trading halts

We investigate the impact of trading halts of NYSE-listed stocks on informationally related securities that continue to trade during the period of the halt. Informational relationships are established for companies in the same four-digit SIC industry based on the correlation of returns, volume, volatility, and the adverse selection components of spreads. We find a significant liquidity impact on informationally related securities with spreads and price impact of trades having substantial increases. However, we also find that quoted depths, the number of trades, and trade volume significantly increase. Our results are consistent with the trading halt model of Spiegel and Subrahmanyam [2000. Asymmetric information and news disclosure rules. Journal of Financial Intermediation 9, 363–403] and with the informed trading model of Tookes [2008. Information, trading, and product market interactions: cross-sectional implications of informed trading. Journal of Finance 63, 379–413]. In addition, our results indicate that there is a common liquidity response of informationally related securities to firm-specific trading halts.     

The impact of mandatory IFRS reporting on institutional trading costs: Evidence from Australia

This study examines the impact of mandatory International Financial Reporting Standards (IFRS) on the market quality of the Australian Securities Exchange (ASX) 200 constituent stocks. Using traditional metrics that are consistent with prior literature (i.e., bid‐ask spreads), the first stage analysis confirms that stock liquidity has improved. However, when the analysis is extended to consider the trading costs incurred by market participants (i.e., execution shortfall), results suggest liquidity has not changed significantly. The paper utilizes rich unique datasets that contain detailed trade information, and findings are robust after controlling for trade difficulty and market conditions. In the era of High Frequency Trading (HFT) and occurrences of ‘fleeting’ liquidity, this paper provides some evidence that while IFRS may have enhanced ‘visible’ bid‐ask spreads, tangible liquidity for market participants, particularly global institutional investors, has not improved significantly.     

Block trading and information revelation around quarterly earnings announcements

I investigate the empirical importance of information revelationin the pricing of block trades. In particular, I examine whetherblock prices are correlated with the unexpected part of firms'quarterly earnings. For my sample of block trades, informationrevelation does indeed appear to be a significant factor shortlybefore earnings announcements.     

The information content of earnings announcements: new insights from intertemporal and cross-sectional behavior

This study examines the information content of quarterly earnings announcements, measured as the magnitude of stock price revision at earnings announcements relative to price revision at other times. We investigate whether quarterly earnings announcements are informative using a nonparametric approach and 1971–2011 sample period. The findings affirm prior evidence on earlier sample periods that significantly more information is conveyed to investors in the three days around earnings announcements than in randomly chosen three-day periods. Next, we examine the behavior of information content over our sample period and document four key findings. First, there is a dramatic increase in information content at earnings dates from 2001 onward. Second, the market reaction to loss firms is substantially less than that for profitable firms. Third, there is a significantly greater reaction to larger firms. Fourth, reaction at earnings dates is significantly increasing in analyst coverage, and once analyst coverage is controlled, the association with size becomes less significant.     

Earnings announcements,private information,and strategic informed trading

In this paper, we estimate and test a multi-period model of strategic informed trading developed by Foster and Viswanathan [Foster, F.-D., Viswanathan, S., 1996. Strategic trading when agents forecast the forecasts of others, J. Finance 51, 1437–1478]. We employ the GMM using intertemporal patterns of price, trading volume and market depth, leading up to the earnings announcements made by NYSE firms. We find that multiple informed traders with heterogeneous private signals trade prior to the announcements. In addition, by comparing the results from daily and intra-day estimations, we find that the number of informed traders increases while the intensity of liquidity trading decreases, and that the adverse selection problem becomes more pronounced as the announcements approach.     

The information content of cash dividend announcements in a unique environment

Due to its distinctive institutional background, Oman offers a valuable opportunity to examine stock price reactions to dividend announcements. In Oman, (1) there are no taxes on dividends and capital gains, (2) there is a high concentration of share ownership, (3) there is low corporate transparency, and (4) firms frequently change their dividends. Our results show that announcements of dividend increases are associated with increased stock prices, while announcements of dividend decreases cause decreases in stock prices. Firms that do not change their dividends experience insignificant negative returns. These results contradict tax-based signaling models, which argue that higher taxes on dividends relative to capital gains are a necessary condition for dividends to be informative.     

The information content of insider trading around seasoned equity offerings

This paper examines insider trading around seasoned equity offering (SEO) announcements in Hong Kong. The announcements of private placings (rights offerings) are associated with positive (negative) abnormal stock returns. However, longer-term stock returns are negative for both private placings and rights offerings. In general, insiders are net purchasers in placing firms in the 6 months prior to and 6 months subsequent to the SEO, whereas insiders are net sellers in rights issue firms in the 6 months prior to and 6 months subsequent to the issue. The net purchases made by the insiders of firms making placements help them maintain their control rights, which are otherwise diluted by the placements. Insider trading does not explain longer-term investment returns.     

Institutional trading and information processing: Evidence from complicated firms and easy-to-analyze firms

In this article, I examine institutional trading within two groups of firms with different demands on investor information processing: conglomerate firms and stand-alone firms. On average, institutional trading in conglomerate firm stocks yields significantly lower returns than institutional trading in stand-alone firm stocks. Inferior returns following institutional trading in conglomerate firm stocks persist across small and large firms. Moreover, financial institutions with a low concentration of conglomerate firms in their portfolios are more profitable in their trading. This study provides evidence that skilled institutional investors intentionally focus their information-processing efforts on easy-to-analyze firms.     

Information-based trading and information propagation: Evidence from the exchange traded fund market

This paper studies the information-based trading of exchange-traded funds (ETFs) and the information propagation from the ETF market to its index. We find that the ETF trading triggered by asymmetric information and belief heterogeneity not only accelerates the ETFs' price discovery process but also increases the flow of information to the tracked index. Moreover, the price efficiency of the index also improves along with these two types of trading and their efficiency effects can be further enhanced by a speedier ETFs' price discovery. These observations portray the mechanism of the inter-market information propagation.     

The relevance of information and trading costs in explaining momentum profits: Evidence from optioned and non-optioned stocks

Considerable evidence from many countries suggests momentum strategies generate profits. These have been difficult to rationalise and evidence on the sources of such profitability is inconclusive. We utilise a sample of optioned stocks, characterised by high liquidity, high market capitalisation and fewer short sales constraints and compare results with control samples of non optioned stocks chosen on the basis of market value, turnover and bid–ask spread. The sample characteristics, and the fact that derivatives improve the impounding of information into prices, enable us to draw conclusions about the causes of momentum profits. While we find that short sales constraints are not the major driver of profitability and that most momentum profits disappear using two transactions costs measures of the bid–ask spread, one not previously used, the persistence of some momentum profits indicates that the market underreacts even to the most publicly available information.     

The information content of CDS implied volatility and associated trading strategies

Using the theoretical link between put options and credit default swaps (CDS) in a very general setting, we develop a robust measure of CDS implied volatility (CIV) that captures the information content of CDS markets. Specifically, we use the unit recovery claim to bridge CDS and deep out-of-the-money put options of the same firm and then back out CIV via the binomial tree. Our CIV measure strongly co-moves with the option implied volatility (OIV), with a correlation coefficient of 0.8. Based on the standardized difference between CIV and OIV, we construct CDS and option trading strategies. Without taking transaction costs into account, the long–short CDS trading strategy achieves an annualized return of 58.29% and a Sharpe ratio of 2.97, which cannot be explained by non-parametric skewness and volatility risk.     

The impact of regulation Fair Disclosure on investors' prior information quality — Evidence from an analysis of changes in trading volume and stock price reactions to earnings announcements

We document that Regulation Fair Disclosure has reduced differences in information quality between investors prior to quarterly earnings announcements consistent with the intent of the regulation. This reduction is driven by small firms and high technology firms, rather than the large firms targeted by the SEC, which suggests that selective disclosure among large firms may have been much more limited than what was presumed by proponents of FD. In addition, we document that FD has decreased the average information quality of investors in small and high technology firms in the period prior to an earnings announcement while having no lasting effect on other firms. Taken together these two results suggest that, for small and high technology firms, FD succeeded in eliminating selective disclosure but also lowered the average quality of information available about these firms.     

Do option markets substitute for stock markets? Evidence from trading on anticipated tender offer announcements

Using a sample of cash tender offers occurring between 1993 and 2002, we find evidence that the options market has become the preferred venue for traders attempting to profit on anticipated announcements. Options offer advantages relative to stocks. Traders gain leverage by trading in options and multiple options contracts on an individual stock. The results of our study indicate that a substitution effect does exist. Abnormal volume in the option market replaces abnormal volume in the stock market prior to cash tender offer announcements, and this abnormal option volume precedes abnormal stock volume for targets with or without traded options.     

The information content of annual earnings announcements and mandatory adoption of IFRS

This study examines whether the information content of earnings announcements – abnormal return volatility and abnormal trading volume – increases in countries following mandatory IFRS adoption, and conditions and mechanisms through which increases occur. Findings suggest information content increased in 16 countries that mandated adoption of IFRS relative to 11 that maintained domestic accounting standards, although the effect of mandatory IFRS adoption depends on the strength of legal enforcement in the adopting country. Utilizing a path analysis methodology, we find evidence of three mechanisms through which IFRS adoption increases information content: reducing reporting lag, increasing analyst following, and increasing foreign investment.     

The short-term impact of director trading in UK closed-end funds

Most closed-end funds are transparent entities that hold securities that are actively traded in liquid markets. In such a setting, the argument that director transactions mitigate information asymmetry has very limited applicability. Our results provide support for the theory of Barber and Odean [2008. “All that Glitters: The Effect of Attention and News on the Buying Behavior of Individual and Institutional Investors.” Review of Financial Studies 21: 785–818]: retail investor decision-making is influenced by attention-grabbing events. Director purchases are one such attention-grabbing event and are associated with significant positive price returns – the magnitudes of which are linked to the size of the purchase, the size of the fund, and the investment mandate. Trading volumes increase at the time of the purchase but most of the initial price responses and trading volumes dissipate over the following 15 days.     

The incremental information content of non-US GAAP earnings disclosures: Evidence from UK firms

This paper examines price and trading volume responses in the US equity market to the preliminary earnings announcements (PEAs) in the UK of UK firms listed on US exchanges (e.g., NYSE and AMEX). The inquiry focuses on whether the return forecast error (absolute and squared values) and volume residual (standardized and unstandardized) for each day were significantly different from the average on the day of the earnings announcements (PEA). The most significantly unexpected return occurred the day prior to the Financial Times (FT) announcement. The results suggest prompt volume and price responses to the UK PEAs in the US security market. Excess trading volume occurred the day prior to and the day of the FT release price response occurred on the day subsequent to the PEAs. This may suggests that investors possess differential prior beliefs or likelihood functions in evaluating public disclosure. Consistent with Frost and Pownall [Frost, C., & Pownall, G. (1996), Interdependencies in the global markets for capital and information: The case of Smithkline Beecham plc. Accounting Horizons, 1, 38-57], US investors seem not to be confused by US/UK generally accepted accounting principles (GAAP) differences, and in fact use information about UK GAAP earnings in their valuations and trading decisions. This implies that traders correctly use UK accounting output to the determination of values in setting security prices and arriving at trading decisions. Broadly, these findings support the assumption that disclosures by UK-listed firms in their domestic market influence share liquidity and trading in the US market.     

Information content of options trading volume for future volatility: Evidence from the Taiwan options market

This study follows the approach of Ni et al. [Ni, S.X., Pan, J., Poteshman, A.M., 2008. Volatility information trading in the option market. Journal of Finance 63, 1059–1091] – based upon the vega-weighted net demand for volatility – to determine whether volatility information exists within the Taiwan options market. Our empirical results show that foreign institutional investors possess the strongest and most direct volatility information, which is realized by the delta-neutral options/futures trades. In addition, a few individual investors (less than 1% of individuals’ trades) might be informed and realize their volatility information using the strangle strategy. Surprisingly, we find no evidence to support the predictive ability of the volatility demand from straddle trades, despite the widespread acknowledgement that such trades are sensitive to volatility.
