Asset Liquidity and Stock Liquidity: International Evidence

This study examines the relationship between asset liquidity and stock liquidity across 47 countries. In support of the valuation uncertainty hypothesis, we find that firms with greater asset liquidity on average have higher stock liquidity. More importantly, our study shows that asset liquidity plays a more significant role in resolving valuation uncertainty in countries with poor information environment. For example, we find that the asset–stock liquidity relationship is stronger in countries with poor accounting standards. We further find evidence that after the adoption of IFRS, the improved accounting information environment results in a weaker asset–stock liquidity relation, but only in countries with a strong legal regime. Finally, our study shows that the positive asset–stock liquidity relationship may be attributed to transparency and/or liquidity reasons.     

An Empirical Analysis of Quoted Depths of NYSE and Amex Stocks

In this study, we find strong intertemporal/cross-sectional correlations between quoted depths and various security characteristics for a sample of stocks listed on the NYSE and Amex. Our empirical results indicate that although specialists are generally unable to discern insider trading as it occurs, they cope with insider trading by posting smaller depths for stocks with a greater tendency of insider trading. Empirical evidence also indicates that specialists/limit order traders quote smaller depths for riskier stocks to limit potential losses to better-informed traders. In addition, we find that specialists/limit order traders quote larger depths for stocks with greater trading volume, larger market capitalization, and higher competition. Overall, our findings suggest that depths are an important means through which specialists and limit order traders deal with the adverse selection problem, order processing problem, and competition.     

Penny pricing and the components of spread and depth changes

Recent studies show that decimal pricing led to significant reductions in the spread and depth on the NYSE. In this paper, we examine how the observed changes in the spread and depth can be attributed to different factors. We show that stocks with higher proportions of one-tick spreads and odd-sixteenth quotes, and more frequent trading before decimalization experienced larger declines in the spread and depth afterwards. We interpret this result as evidence of reduced binding constraints and increased price competition under decimal pricing. We also find that decimal pricing led to nontrivial changes in select stock attributes, and that these changes exerted an additional impact on spreads and depths. Our results suggest that sub-penny pricing may further reduce the spreads of high-volume, low-risk, or low-price stocks.     

A Note on Intraday Event Studies

Abstract

We investigate the specification and power of intraday event study test statistics. Mean, market, and matched firm models generate well-specified return results for a range of intervals up to 60?min around the event. These models detect return shocks equivalent to one spread in one-minute interval data and three spreads in longer intervals. Researchers using intraday return event studies can, therefore, be confident in their robustness. Some volume event study approaches have reasonable power but they are not generally well specified, while a matched-firm approach gives the best combination of specification and power for spread event studies.     

Sell the rumour,buy the fact?

We document a high‐profile instance of mispricing that is puzzling given the gradual information diffusion hypothesis and the lack of obvious limits to arbitrage. An internet search in 2008 led to a story about United Airlines’ 2002 bankruptcy being re‐released as ‘news’. This resulted in United Airlines losing 73 per cent of its value and caused a $4.2 billion decline in the value of airline stocks and United Airlines suppliers. The incorrect bankruptcy ‘news’ was quickly retracted, which led to a rebound in other airline and supplier firms, but the stock price of United Airlines was adversely affected for 4 days.     

Liquidity distribution in the limit order book on the stock exchange of Thailand

The liquidity distribution, or the shape of the limit order book, influences trading behavior and choice of order submission by public liquidity suppliers. The present study seeks to discover whether liquidity providers are concerned about being picked off by informed traders, and whether they are less willing to supply liquidity at the market or demand higher price spreads. The results show that liquidity at the market is a small portion of total liquidity, and that firm size, minimum tick size, volatility, and trading volume play significant roles in determining the liquidity distribution within an order book.     

Insider Trading and the Bid-Ask Spread

This study examines the intertemporal and cross-sectional association between the bid-ask spread and insider trading. Empirical results from the cross-sectional regression analysis reveal that market makers establish larger spreads for stocks with a greater extent of insider trading. The time-series regression analysis, however, finds no evidence of spread changes on insider trading days. These results suggest that although market makers may not be able to detect insider trading when it occurs, they protect themselves by maintaining larger spreads for stocks with a greater tendency of insider trading. The results also reveal that market makers establish larger spreads when there are unusually large transactions. In addition, this study finds that spreads are positively associated with risk and negatively with trading volume, the number of exchange listings, share price, and firm size.     

Adverse selection and corporate governance

This paper examines the impact of corporate governance on the adverse selection component of the bid-ask spread of stocks listed on the Singapore Exchange. These companies have been identified by Credit Lyonnais Securities Asia (CSLA) with the highest level of corporate governance among 25 emerging markets. We measure corporate governance by several criteria: discipline, transparency, independence, accountability, responsibilities, fairness, and social awareness. The results show that corporate governance has an inverse relationship with adverse selection. However, only the transparency dimension exhibits a significant inverse relationship with adverse selection. In addition, Government-Linked Companies (GLCs) are shown to have a smaller adverse selection component than non-GLCs.     

Earnings management to exceed thresholds: Evidence from Singapore and Thailand

Earnings play a vital role in portraying a company's economic health. Hence, executives have incentives to manage earnings. Motivated by Degeorge et al. [Degeorge, F., Patel, J., Zeckhauser, R., 1999. Earnings management to exceed thresholds. Journal of Business 72, 1–33] and Burgstahler and Dichev [Burgstahler, D., Dichev, I., 1997. Earnings management to avoid earnings decreases and losses. Journal of Accounting and Economics 24, 99–126], this study applies the behavioral framework developed by Degeorge et al. [Degeorge, F., Patel, J., Zeckhauser, R., 1999. Earnings management to exceed thresholds. Journal of Business 72, 1–33] to investigate earnings management to exceed thresholds in Singapore and Thailand. The empirical evidence reveals that earnings management exists in Singapore and Thailand to avoid reporting losses and negative earnings growth. This earnings management practice, however, varies between financial and non-financial firms, between Singaporean and Thai firms, and between before and after the Asian financial crisis in 1997. Moreover, corporate governance structure is found to impact the extent of earnings management to exceed thresholds in Singapore.
