本文运用T-M模型和H-M模型,采用2012—2013年的交易数据,对我国已上市的21只沪深300指数基金的择时选股能力进行实证分析。实证结果显示:我国沪深300指数基金经理的选股能力较差,基金经理未能给投资者带来超额收益;在择时方面,基金经理普遍具有一定的择时能力,但不具备强择时能力;基金经理的择时能力和选股能力呈强烈的负相关性。  相似文献

本文选取2009年前成立的8只QDII基金为研究样本,以2009年和2010年的周度数据为基础,采用TM和CL模型对QDII基金经理的选股能力和择时能力进行实证分析。实证结果表明,我国QDII基金经理的选股择时能力不具有持续性。2009年有较强的选股能力和择时能力,2010年有一定的选股能力,但是缺乏择时能力。进一步分析,QDII基金经理的选股择时能力的显著性都不强。  相似文献

近年来,开放式基金逐渐成为我国基金市场的绝对主体。开放式基金能否取得较好的绩效受到市场的普遍关注。本文选取了资金管理规模前20位的公司,并从中随机挑选1只基金,运用詹森指数、特雷诺比率、夏普指数和信息比率等单因素模型和Fama-French三因素模型对开放式基金的绩效进行分析,并使用T-M模型、H-M模型、C-L模型对基金经理人股票选股与择时能力进行分析。结果发现:第一,我国开放式基金经理的选股能力存在时变性,在上升期具备选股能力,在下跌期不具备选股能力,而无论是在上升期还是下跌期,基金经理普遍不具备择时能力。第二,在市场上升期基金经理比较注意对风险的把控,系统性风险较小,而在下跌期基金投资组合的系统性风险明显上升,基金经理冒险意愿上升,当市场出现大幅度下跌时,其不理性行为会加剧市场的波动。本文的研究结论有利于提升投资者的风险意识和理性意识、促进外部监管部门的精准监管审查,并能够激励基金经理人提高自身风险管控的能力。  相似文献

本文利用分时段比较研究中国三种主要开放式基金在股市涨落中是否存在选股择时能力,以帮助投资者对其形成初步的认识。研究发现,目前的两种主要评价模型更适合在市场相对平稳时期评价中国基金的选股择时能力。当市场剧烈波动时,模型解释力较弱;基金总体仅具有极为微弱的选股能力,择时能力欠佳,且不同类型基金在市场不同波动阶段选股择时能力差异较大;市场下降期往往同时具有一定的选股和择时能力,但其他时段两种能力则具有较强的负相关性。  相似文献

基金作为重要的机构投资者,长期面临赎回率高企问题,不利于基金公司成熟稳健发展。本文聚焦基金公司的治理特征对于基金业绩与赎回行为关系的调节效应,实证分析基金业绩对基金赎回率的影响,从四个层面考察基金公司治理特征的调节效应,从静态与动态双维度视角实证检验其调节效应。结果发现:基金公司的股东规模、股权集中度、基金经理的团队、机构投资者的市场规模及其市场占比对基金业绩和基金赎回率具有显著的正向调节效应;基金公司的董事会规模与基金经理的性别对基金业绩和基金赎回率具有显著的负向调节效应,而独立董事规模与基金经理学历的调节效应不显著。  相似文献

开放式基金现已成为我国证券市场上最重要的投资机构和我国基金市场的主流。开放式基金的选股和择时能力是其获得超额收益的重要因素,本文选取17只基金作为样本并运用T-M和H-M模型对其选股能力和择时能力进行实证分析,就选股能力而言,均显示少数样本基金具备选股能力。就择时能力而言,均显示所有的样本基金均不具备择时能力。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

The separation of a unit of account (UoA) from a medium of exchange (MoE) in the commodity–money system is investigated by considering explicitly a seller's choice of UoA in terms of either an MoE or a unit of metal weight. If the likelihood of debasement of an MoE and its rate are high enough, the price is posted in terms of a unit of metal weight rather than an MoE. Interestingly, this MoE–UoA separated equilibrium yields the flexible nominal price, whereas an MoE–UoA integrated equilibrium yields the sticky one. This implies the nominal price rigidity in the fiat‐money system where MoE and UoA are integrated.  相似文献

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…  相似文献
