50ETF对其成份股波动性影响的实证研究

本文探讨了50ETF对上证50指数成份股的波动影响情况。本文使Andersen et al．方法和GARCH模型的无条件方差测度上证50指数成份股的波动性变化，实证结果显示，ETF的设立显著提高了上证50成份股的波动性；ETF对不同市值规模股票的波动性影响不存在显著差异，但对不同行业的波动性影响存在明显差异。本文认为ETF价格变化可以反映市场信息以及改变投资者的资产配置，进而影响其对应成份股价格的波动性变化。     

期权交易能提高标的资产的定价效率吗?——基于上证50ETF套利视角的实证研究

随着上证50ETF期权的推出,期权交易能否提高标的资产定价效率的问题显得愈发重要。本文从对定价效率影响最大的套利机制入手,研究上证50ETF期权推出前后,其对应标的——华夏上证50ETF市场价格和净值的偏差所带来套利机会的多少,进而得出期权交易对标的资产定价效率的影响。研究发现:期权交易在刚推出的一定时间内降低了标的资产的定价效率,但是随着时间的推移,标的资产的定价效率会重新提高并且超过初期。因此从长期看,期权交易能够提高标的资产的定价效率,期权交易对标的资产的定价效率的影响是一条"J"形曲线。     

股票停牌、涨跌停与ETF定价效率——基于上证50ETF日度数据的实证研究

本文应用中国股市2007年至2011年的数据,研究了上证50ETF市场价格和基金净值的相关关系,以及折溢价水平及其影响因素。基于ETF的申购赎回和交易机制,在成分股涨跌停板和停牌期间,由于ETF二级市场价格具有价格发现功能,ETF市场价格可能较大偏离(形式上的)ETF净值,造成ETF的异常折溢价,而此类异常折溢价并不是真正的套利机会。另外,上证50ETF的市场价格与基金净值存在显著同步变动的关系;在涨跌停板和停牌期间之外,上证50ETF的折溢价水平低于套利所需的交易成本。本文研究表明,上证50ETF具有较高的定价效率。     

ETF基金套利研究——以上证50ETF、上证180ETF为例

本文在分析ETF基金特点的基础上,提出了5种不同的ETF基金套利交易模式,并认为在二级市场上,通过融资融券建立ETF-ETF套利组合是适合普通投资者的套利模式.本文以上证50ETF、上证180ETF为例,在分析其标的指数收益率内在联系的基础上,提出了建立上证50ETF、上证180ETF套利组合的方法,使用国泰安数据库相关数据进行了模拟分析,得出该套利组合获得正利润的结论.最后,论文指出了在二级市场建立ETF-ETF基金套利交易的模式存在基差风险的三个原因     

上证央企50指数现期投资价值分析

国泰君安一项研究报告显示,上证央企50ETF指数的成份股全部包含在沪深300指数成份股之列,投资者可以利用上证央企ETF进行股指期货的期现套利操作,其实证研究也表明有较好的抽样效果和跟     

关于华夏上证50ETF近期市场表现的实证研究

本文借鉴国内外研究成果,对2017年10月10日至2019年2月26日华夏上证50ETF市场表现进行了实证分析。研究结果表明,华夏上证50ETF较好地复制了其标的指数,误差来源于自身及标的指数的波动性,主要表现为复制误差。其次,对市场套利行为的研究发现前一日的较高折溢价水平并不会引起当期二级市场价格收益率的大幅变化。文章将前一期折溢价水平对当期交易量的影响分析作为稳健性检验,发现折溢价水平并不会对当期交易量造成主要影响,从而得出近年来市场套利行为不活跃的结论。     

对上证50交易型开放式指数证券投资基金的实证研究

本文在借鉴国内外相关文献的基础上,对上证50交易型开放式指数证券投资基金(上证50ETF)的市场表现进行了实证研究。研究结果表明,上证50ETF在我国运行以来的市场表现是相对稳定的,其收益基本实现了对上证50指数的复制;但两收益率之间也存在跟踪误差,上证50ETF的管理费和股利分配是造成这种跟踪误差的重要原因。其次,对上证50ETF折、溢价水平的定量分析则表明上证50ETF较成功的套利机制保证了其二级市场价格的有效性,并且该价格的变动与上证50ETF的折溢价水平密切相关;但套利和折、溢价水平并不能有力地解释上证50ETF二级市场的交易量。三者虽然密切联系,但后者显然还与其他很多因素有关。     

关于“ETF风险论”的辨析

交易所交易基金(ETF)是近年来全球市场最受瞩目的创新投资工具,ETF市场快速发展。然而,有观点认为ETF会助长危机事件下的恐慌性抛售、引发系统性风险。本文对ETF的市场影响进行探讨,认为ETF的推出对于规避系统性风险、稳定市场起到积极作用。在ETF纳入融资融券标的后,期现套利过程更加顺畅,进一步缩小期现价差,增加市场流动性。我国当前正面临ETF市场发展的新契机,应积极推进ETF产品向多元化方向发展。     

美国市场1993—2003ETF年度数量

从产品创新的角度看，ETF是一种较为基础层次的衍生证券，可作为突破口为更复杂产品的创新积累经验。ETF的价格取决于其基础资产——标的指数的内在价值，从其结构和特征看，ETF属基础层次的创新产品。在我国现有的证券市场运作机制、监管能力、投资者结构、法规体系等等件下，推出ETF的复杂程度较低，市场容易接受。与ETF相关的比较直接的创新产品和工具有股票指数期货、卖空交易机制等。     

买卖权平价关系偏离能预测现货市场收益吗? ——基于上证50ETF期权的实证研究

选取隐含波动率差指标,以上证50ETF期权为研究样本,研究了期权市场买卖权平价关系偏离能否预测标的资产未来的收益信息.将分组分析和回归分析两种方法相融合,并将样本数据划分为三个不同阶段进行分析,结果显示,在发展初期期权市场包含标的资产未来较短时间内的收益信息,但信息含量很少;随着期权市场的发展,即在发展中期和发展期,期权市场包含标的资产未来更长时间范围内的收益信息且信息方向发生改变;期权市场能否准确预测现货市场信息与投资者情绪显著相关.     

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…
