Intraday Stock Price Reactions to Interim-Quarter versus Fourth-Quarter Earnings Announcements

This study investigates intraday patterns of quarterly return-earnings relations. We find that fourth quarter announcements exhibit a lower earnings response coefficient but a more rapid adjustment to new equilibrium levels of prices and a higher R2 than interim quarter announcements. While prior short event window studies document that interim quarter earnings have greater explanatory power than fourth quarter earnings or annual earnings, our analysis indicates that the prior results may be driven by the use of two-day event window that is much wider than what it takes for the market to adjust to fourth quarter announcements.     

Periodic Information Asymmetry and Intraday Market Behaviour: An Empirical Analysis

The model of Foster-Viswanathan (1990, FV) predicts that informationheterogeneity among market participants generates patterns involume, trading costs and volatility. In the Italian Treasurybond market, periodic information asymmetry is related to thearrival of block orders from international investors, whichcluster soon after the opening of the market and, respectively,of the US market. Our evidence is that volume is lower and tradingcosts are higher after the two openings, consistent with FV.We find only weak evidence that volatility behaves as impliedby the model.

Intraday Empirical Analysis and Modeling of Diversified World Stock Indices

This paper proposes an approach to the intraday analysis of diversified world stock accumulation indices. The growth optimal portfolio (GOP) is used as reference unit or benchmark in a continuous financial market model. Diversified portfolios, covering the world stock market, are constructed and shown to approximate the GOP, providing the basis for a range of financial applications. The normalized GOP is modeled as a time transformed square root process of dimension four. Its dynamics are empirically verified for several world stock indices. Furthermore, the evolution of the transformed time is modeled as the integral over a rapidly evolving mean-reverting market activity process with deterministic volatility. The empirical findings suggest a rather simple and robust model for a world stock index that reflects the historical evolution, by using only a few readily observable parameters.

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.

中国货币供应量与股票市场价格关系的实证分析

股票市场作为货币政策传导的渠道,一方面通过货币供应量影响股票市场价格,另一方面股票市场价格的变动反馈到投资、消费等领域,从而影响宏观经济以实现货币政策的目标。本文对我国货币供应量与股票市场价格关系进行了实证检验,分析检验结果后认为我国各层次的货币供应量与股票市场价格存在长期的协整关系,其中股票市场价格处于因方地位,货币供应量处于果方地位。本文的实证结论在一定程度上反映了目前我国股票市场的货币政策传导效率不高,还没有发挥其应有的作用,这与我国股票市场自身缺陷有很大关系。     

Intraday Price Change and Trading Volume Relations in the Stock and Stock Option Markets

This study investigates intraday relations between price changes and trading volume of options and stocks for a sample of firms whose options traded on the CBOE during the first quarter of 1986. After purging the price change series of the effects of bid/ask spreads, multivariate time-series analysis is used to estimate the lead/lag relation between the price changes in the option and stock markets. The results indicate that price changes in the stock market lead the option market by as much as fifteen minutes. The analysis of trading volume indicates that the stock market lead may be even longer.     

我国农村资金供求缺口分析

资金投入对于农村经济发展至关重要.目前,我国农村资金需求数量在不断增加,与此同时,尽管农村资金的供应也在增加,但其增长幅度远不及农村资金需求的增长速度,存在巨额的农村资金供求缺口,特别是农村资金外流加大了农村资金供求缺口.因此,一方面应增加农村资金供应;另一方面应采取措施防止农村资金外流.     

资本市场上信息的特点及其供求机制分析

资本市场是以信息为轴心的市场,也是信息最不对称的市场。从系统论的角度看,资本市场本身就是一个信息运行系统,它由信息供给、信息需求、信息传播与流通等组成。信息在资本市场的重要性要求我们,一方面通过信息供求机制和传播渠道保证信息的生产、交流的顺畅;另一方面,坚持资本市场的“市场化”趋向,尤其是要建立完善的强制性信息披露制度,减缓资本市场信息不对称程度,实现资本市场的公平交易和有序运行。     

Earnings Persistence and Stock Market Reactions to the Different Information in Book-Tax Differences: Evidence from China

Prior studies document that book-tax differences (BTDs) reflect divergent reporting rules for book and tax purposes, and contain information about earnings management and tax planning. In this paper, we investigate whether the regulatory and opportunistic information impounded in BTDs differentially influences earnings persistence and the earnings–returns relation. Using BTD data from China, we separate BTDs into normal BTDs (NBTDs) and abnormal BTDs (ABTDs). NBTDs are more likely driven by regulatory differences between accounting and tax rules and ABTDs are more likely driven by earnings and tax management activities. We find that firms with large positive and negative ABTDs (NBTDs) exhibit less earnings persistence compared to firms with small ABTDs (NBTDs). However, the level of earnings persistence for large unsigned ABTD firms is significantly lower than it is for large unsigned NBTD firms. While large unsigned NBTDs appear to enhance the earnings–returns relation, we find no evidence that large unsigned ABTDs affect the earnings–returns relation. Overall, the results suggest that the differing components of BTDs have differential implications for earnings quality. Additional tests show that ABTDs and NBTDs can provide incremental information about earnings persistence beyond the information in discretionary accruals and total accruals, suggesting that the investigation of BTDs adds value to financial analysis.     

Intra-Industry Reactions to Stock Split Announcements

We examine whether favorable information conveyed by stock split announcements transfers to nonsplitting firms within the same industry. On average, nonsplitting firms' shareholders experience positive and significant abnormal returns at the stock split announcements of their industry counterparts. In addition, industrywide and firm-specific characteristics are important determinants in explaining nonsplitting firms' stock returns. These firms' earnings increase significantly, and the earnings changes are positively related to the stock price reactions. Finally, we find no evidence that investors revise the value of nonsplitting firms because they anticipate a decline in earnings volatility.     

Stock Price Response to News of Securities Fraud Litigation: An Analysis of Sequential and Conditional Information

This study examines investor response to three events that help define a federal class action securities lawsuit, specifically, the announcement that names an issuer as a defendant in the lawsuit (at the class action filing date), the disclosure or accounting restatement that 'corrects' the information deficiency (at the end of the class period), and the date at which the fraud on the market allegedly begins (at the beginning of the class period). We document a significant and predictable stock price response at each of these three events. Our tests also indicate that the market interprets these events not in isolation but as sequential and conditional events. Investor response differs on the basis of the characteristics of the issuer, the allegations in the complaint, and the outcome of the litigation. These results and the fact that we observe no systematic price momentum in investor response beyond the announcement dates imply that the market is reasonably efficient with respect to information about securities fraud litigation. Our results are robust to alternative definitions and procedures, and are based on a proprietary database that includes almost all federal securities class action lawsuits since 1990.     

The Informational Efficiency of the Corporate Bond Market: An Intraday Analysis

Using a unique dataset based on daily and hourly high-yieldbond transaction prices, we find the informational efficiencyof corporate bond prices is similar to that of the underlyingstocks. We find that stocks do not lead bonds in reflectingfirm-specific information. We further examine price behavioraround earnings news and find that information is quickly incorporatedinto both bond and stock prices, even at short return horizons.Finally, we find that measures of market quality are no poorerfor the bonds in our sample than for the underlying stocks.

大小非减持、理性恐慌与股市暴跌

在不完全信息理性预期均衡的框架下,基于Barlevy和Versones(i2003)的框架,研究大小非解禁背景下不同投资者理性恐慌与股市暴跌之间关系,得出股市暴跌是由理性的无信息交易者所引起的。暴跌的程度取决于市场中无信息交易者的比例、简单被动投资的数量和大小非减持的数量,且大小非减持能够改变股票暴跌的程度,使得高资产价值股票可能的暴跌程度大于低资产价值股票可能的暴跌程度。     

Stock Market Reactions and Information Transfer Due to Financial Instability in the Life Insurance Industry

ABSTRACT: This study examines the stock market reactions and information transfer effects due to financial instability for four life insurance companies that eventually failed or were taken over by regulators. The four companies were First Executive Corporation, First Capital Holdings Corporation, Monarch Capital Corporation, and Mutual Benefit Life Insurance Company. In general, significant negative capital market responses were found after a company released an announcement regarding financial instability. Information transfer effects of a negative announcement by one insurer were not found to have a significant impact on the other insurers. This study complements past studies of contagion effects within the insurance industry.     

会计信息供需矛盾的探讨

会计信息是一种特殊的商品,即"公共商品",因此也适用经济学的供求定理。根据这一定理,当会计信息的供给与需求不相等时,就会产生会计信息的供需矛盾。会计理论本身固有的局限性是会计信息供需矛盾产生的内在因素,会计环境的不断变化是会计信息供需矛盾产生的外在原因。解决会计信息供需矛盾的对策:一是充实与改进会计理论与会计方法;二是完善会计准则与会计制度;三是改善会计环境。     

Intraday Lead-Lag Relationships Between the Futures-, Options and Stock Market

In rational, efficiently functioning and complete markets, returnson derivative and underlying securities should be perfectlycontemporaneously correlated. Due to market imperfections, oneof these markets may reflect information faster. The use ofhigh-frequency data and the choice for a small unit time intervalto measure these lead-lag relations comes at the cost of someor many missing observations, causing traditional estimatorsto either under- or overestimate covariances and correlations.We use a new estimator to estimate lead-lag relationships betweenthe cash AEX index, options and futures. We find that futuresreturns lead both options and cash index returns by approximately10 minutes. The relationship between options and the cash marketis not completely unidirectional.
