本文运用DeBondt和Thaler的研究方法,选取我国上海和深圳两大证券市场的股票交易数据,通过构建输家组合和赢家组合进行分析.研究的结果表明,在我国金融市场在不同的时期,分别表现出反应过度和反应不足的特征.在我国市场上,投资者单纯使用反转策略或者惯性策略都不能持续的获取高收益     

中国股市个股非流动性、换手率和短期反转的关系

本文在排除买卖报价反弹、周末效应等干扰因素的前提下,利用分组构建逆势投资组合及Fama-Macbeth回归方法,研究周期下我国股市中的短期收益反转现象。实证结果表明：我国股市中存在短期收益反转现象,短期反转在股票输家中表现更为明显;股票收益的短期反转随着非流动性的增强而增强;我国股市具有极高换手率的投资组合表现出特殊性,极高换手率对股票输家的短期收益反转具有抑制作用,而对股票赢家的短期收益反转具有促进作用。     

基于牛市和熊市不同周期的股票市场动量效应研究

在参考国外研究方法的基础上,以周作为检验周期,将1997年6月至2001年6月的股市作为牛市,2001年6月至2005年6月的股市作为熊市,然后分别检验股市在这两个不同时期的动量效应.研究发现,赢家组合在牛市中存在着正的动量效应,输家组合在熊市中存在着负的动量效应.而牛市中的输家组合和熊市中的赢家组合都存在着价格的反转.

重仓股停牌削去基金净值几何

2008年二季度,国内股市经历了近乎崩盘的下跌行情.在此过程中,一些股票由于各种因素处于停牌状态.暂时避免了停牌期间的系统性风险.但在弱势环境下,一旦此类股票复牌恢复交易,将不可避免地出现补跌行情.从2008年一季度的基金报告看,共有10只重仓股陆续处于停牌状态,见表1.随着这些股票的陆续复牌,将很可能对持有此类股票的基金净值产生负面影响,相应基金净值将存在潜在的下跌风险.     

创业板颇受公募基金青睐

今年以来,在沪深300指数下跌8.11%的情况下,股票型基金上涨15.67%,表现最好的基金上涨了77.70%,可见在这阶段公募基金的表现明显优于市场。据公募基金二季报显示,纳入统计的336只股票型基金中有209只基金在前10大重仓股中出现了创业板的身影,也就是说二季度末有62.20%的股票型基金重仓了创业板个股。而2012年年末仅有不到38%的股票型基金重仓创业板个股。从数量来看,2012年年末累计205只创业板个股进入基金重仓股中,到了今年年中这个数字升至492只。从市值来看,今年     

索罗斯押注黄金大获全胜的启示

<正>在这一轮英脱欧黑天鹅事件中输家肯定是风险偏好较高,投资于股市等交易性市场的投资者。那么赢家是谁呢?有没有趁火打劫的赢家呢?当然有,索罗斯就是大赢家。英国脱欧公投结果出来后,全球市场为之大动荡。英镑暴跌,欧元下跌,人民币走低,美元日元上涨,国债收益率下降,黄金价格暴涨。全球市场风险偏好达到了低点,避险情绪异常高涨。投资资金撤离     

基于二阶段动态博弈的基金竞赛行为理论证明

本文旨在运用二阶段动态博弈模型从理论上诠释基金竞赛行为的存在。结果显示输家与赢家之间相对风险大小与年中双方收益率差距的大小相关,调整风险行为决定与管理者之间的业绩差距,当业绩差距相对较高时,输家为追赶赢家会选择风险高的投资策略来获得业绩的相对优势,当业绩差距相对较低时,赢家为防止优势地位的丧失会选择比输家风险更大的投资策略;投资者选择行为的变化导致基金经理的投资策略、风险调整行为发生巨大的变化,并且投资者对基金业绩、排名的反向选择行为导致在正向选择行为下将会出现的输家相对于赢家的增加风险行为消失。     

关键看股改

进入6月．大盘表现可谓惊心动魄，先是6月6日上证综指跌破1000点，创出998点新低，“千点论”一语成谶，从预言变成了现实．然后是6月8日突如其来的“井喷”，短线急升148点，“井喷”行情唤起了市场的做多热情，短短两个交易日．两市合计成交超过600亿元，一时间关于“反弹”还是“反转“的争论再次充斥坊问。大盘在两三日的暴涨后迅速转为震荡调整，伴随基金仓位调整，基金重仓股被大量抛售，蓝筹股大面积下跌，大盘再呈弱势。     

Almanac of anticipations: The age of affluence—of anticipation—of anxiety—of automation—of discontinuity—of longing—of overkill—of space exploration

With this survey of developments in the futures field since 1945, I.F. Clarke completes his present series for Futures. He makes two major points: that forecasting techniques have become essential tools in the management of change; and that nuclear weapons and ecological problems have added a moral dimension to the study of the future. In the next issue of Futures he will start a new series on the range of future-thinking in the USA, from the expectations of the first settlers to the Star Wars programme.

对基层人民银行科技工作的几点建议

银监会分设后,人民银行将专司货币政策、金融稳定、金融服务三大职能。作为人民银行的分支机构,基层人民银行的工作重心也将从金融监管调整到这三大职能上来。人民银行的科技部门,就要积极运用科技手段,为人民银行履行新的职能发挥“服务、支持、促进、发展”的作用。一、围绕三大职能搭建五大平台经过“六五打基础、七五作准备、八五大发展”几个阶段后,人民银行相继实现了核算电算化、清算网络化和办公信息化。特别是近一两年来,陆续开通了大额支付系统、信贷登记咨询系统、会计四集中系统、金融信息服务网站等系统,人民银行信息化水平又…     

Properties of time-series estimates of degree of leverage measures

Empirical studies suggest that time-series regression estimates of the degrees of operating and financial leverage have a tendency to produce measures less than one. According to ex ante theory, these measures should be greater than one for firms operating above the breakeven point. There have also been suggestions that the biases in these estimates may be attributable to an underlying increase in unit sales. This work presents evidence that these counter-intuitive measures are produced by changes in the firm's operating parameters (unit price, variable cost, fixed cost and interest payments). It further suggests that attempts to control for the underlying change in unit sales substantially increase the volatility of predicted estimates.     

浅议金融机构的举证责任

金融纠纷案件是当事人以存单或进账单、对账单、存款合同、保险单、票据、证券等凭证为主要证据向人民法院提出诉讼的案件,对于不同种类金融纠纷的当事人的举证责任,我国现行的金融法律、法规及司法解释有不同的规定。由于金融机构的特殊法律地位,发生金融纠纷时存在有关当事人将最后偿付风险转移给金融机构承担的主观故意,在客观上会使金融机构难以提供相应的证据来对抗不法债权人的诉讼请求,而导致金融机构败诉。为此,对金融诉讼案件中金融机构的举证责任加以研究具有重要的实践意义。     

Summary of Results of Survey of Seminar Attendees

Abstract

The Society of Actuaries undertook a three-phase research project on mortality improvement in the three NAFTA countries: Canada, Mexico, and the U.S. Phase 1 consisted of a literature review of papers on projecting mortality levels in the future and a study of the trend in mortality improvement during this century. Phase 2 consisted of a discussion of different facets of modeling mortality rates at a seminar attended by 79 experts (actuaries, demographers, economists, and medical researchers) representing different countries. The last session of the seminar consisted of the completion of a survey by the attendees to obtain input for Phase 3, which would analyze the impact of mortality improvement on the social security system of each country. This paper summarizes the results of the survey.

The survey results illustrate the difficulty in forecasting mortality levels, because the effects of many factors that could have significant impact on mortality rates are unknown. This suggests the need for dynamic forecasting, which allows for the possibility of random shocks. A majority of the survey respondents believe that stochastic forecasting models, despite their complexity, have significant potential to add value. Respondents also believe that both historical data and cause-specific mortality forecasts are useful as input and also in validating forecasts of the aggregate levels of mortality. The challenge is to develop more sophisticated forecasting models to produce results that are relatively easy to interpret and to communicate these results to the desired audiences, including the public and policymakers.

The survey results suggest that the aggregate effect of lifestyle changes, medical advances, diseases, catastrophe, and physical environmental changes is an increase in life span. However, there is much uncertainty about the future. Respondents expect that beyond the year 2020 the mean annual rate of reduction in mortality for males age 65 and over will average about 0.58% for Canada, 0.76% for Mexico, and 0.67% for the U.S. The results for the female age 65 and over population are 0.64%, 0.83%, and 0.70%, respectively. The age 65 and over population is expected to see larger percentage reductions in mortality than the 0–14 and 15–64 populations. The reductions in male and female mortality will be ultimately the same, and the mortality levels in the three countries will ultimately converge, although differences may persist for decades.     

The Usefulness of Measures of Consistency of Discretionary Components of Accruals in the Detection of Earnings Management

Abstract:  Prior research has shown the prevalence of measurement error in models used to estimate aggregate discretionary accruals. In these models, the incremental information content of the various components of accruals is ignored. Limited prior research and data gathered from firms under Securities and Exchange Commission (SEC) litigation indicate that managers use either one or more than one component of accruals simultaneously, in a consistent way to manipulate bottom-line earnings in a given direction. I propose two measures that capture the consistency between the discretionary components of accruals and test their significance in earnings management (EM) detection in firms that have artificially added accrual manipulation and firms that were targeted by the SEC for accrual manipulation. There is evidence that this information is incrementally useful in detecting EM. This finding paves the way for improvements in the discretionary accruals measure by including consistency information from the components of aggregate accruals.     

银行软件项目外包管理分析

一、引言随着国民经济的不断发展,银行业务与外部企业的联系越来越密切。银行正逐步成为现代经济活动的中心,作为数据处理核心的银行业务应用也越来越大型化、越来越复杂化,因此许多银行也把软件项目逐步由原来的自主开发转变为与公司合作的方式,或直接外包开发的方式,银行本身的技术人员也逐步由开发转向项目管理。二、项目外包的分类银行项目的外包有以下几种情况:①部分子系统外包,有时由于银行的软件项目太大,单靠银行自身的开发力量基本无法在预定的时间内完成项目,只好把相对独立的部分外包;②直接购买软件公司的成熟产品,有些金融软…
