火竞赛观点探讨基金经理人的风险调整行为 总被引:1,自引:0,他引:1
竞赛假说将共同基金的市场环境比喻为一项持续、激烈的年度竞赛.本文探讨定期绩效评估系统对于基金经理人所持投资组合风险调整的影响,以检验其是否具有自利性风险调整的行为倾向.研究结果发现:国内基金市场的竞争日趋激烈,基金公司数目日益增加,业绩相对较差的基金经理人有加大风险调整比率的倾向.此外,新基金对投资风险的调整程度,会比老基金来得大. 相似文献

本文引入反映基金经理行为因素的投资风格变量,探讨基金经理个人特征对基金绩效的影响,并分别对牛市和熊市两种不同行情下基金经理个人特征及投资风格与基金绩效之间的相关关系进行分析.在此基础上,将基金极端业绩分布引入模型,对研究进行拓展.研究结果表明:基金经理的性别、学历背景等个人特征能够显著地影响投资风格,而这些个人特征对基金绩效的影响主要通过换手率、持股集中度、行业集中度等投资风格变量来传递;在牛市和熊市两种不同行情下,基金经理个人特征及投资风格对基金绩效和极端业绩分布的影响存在差异. 相似文献

基金业绩评价的实证研究 总被引:16,自引:1,他引:16
通过实证研究我们发现,证券投资基金的生绩水平不存在规模效应,管理人效应和设立时期效应;基金的资产组合风险一般较低,倾向于稳健或保守,基金管理人的投资理念和风格也没有多大差异;基金生绩中都包含一定的超常收益,不同基金的超常收益存在较大差异。 相似文献

本文首次研究了基金在交叉管理模式下的表现.在这种模式下,基金经理通过管理的基金与其他经理形成了一种网络关联.本文利用复杂网络中心度来考察基金经理在经理网络中的特征,以此来研究对其管理的基金的影响.实证发现,基金经理参与管理越多的基金,其中心度数值就越高,其管理的基金的超额收益就越差.中心度高的经理,越倾向承担高风险,而... 相似文献

This study analyzes the risk-taking behavior of mutual funds in response to their relative performance over the 1992 to 1999 period. Our results show that managers of funds whose performance is closer to that of the top performing funds have greater incentives to increase their portfolios' risk than managers at the top who exhibit a tendency to lock in their positions. The evidence suggests that termination risk imposes a constraint on the risk taking behavior of under-performing fund managers and the winner takes all phenomenon generates a strong incentive for the fund managers to be the top manager. We also analyze the difference in the risk taking behavior of funds managed by multiple managers and single managers. 相似文献

资产配置对基金收益影响程度的定量分析 总被引:4,自引:2,他引:4
资产配置是证券投资决策的首要环节,它可分为战略性资产配置及包括选时和选股在内的战术性资产配置.资产配置不但影响了基金业绩沿时间的变化,还对基金之间的业绩差异具有较高的解释程度.本文利用中国的市场数据,度量了资产配置对基金收益的影响程度. 相似文献

保险资金的证券投资绩效分析 总被引:1,自引:0,他引:1
本文回顾了保险资金在证券投资领域的政策变化历程,分析了保险资金运用效率与基金业绩评价的诸多不同,指出了基于资产组合优化理论的保险资金评价方法的不足,提出用影子组合法,作为一种正向制度激励,对保险资金运用效率进行评价,并基于该方法对三家上市保险公司的资金运用效率进行了比较。 相似文献

基金投资风格漂移及其对基金绩效的影响研究 总被引:8,自引:0,他引:8
本文选取一轮完整行情为研究期间,并将其划分为牛市和熊市两个子期间,采用Sharp(1992)提出的基于收益率的投资风格分析法确定基金在两个子期间的实际投资风格,将动态的实际投资风格和宣称的投资风格进行比较,对整个研究期问的“风格漂移”现象进行了研究。在此基础上,考察了“风格漂移”对整个研究期问基金绩效的影响。研究发现,发生明显“风格漂移”的基金绩效要优于未明显发生“风格漂移”基金的绩效。 相似文献

基金业绩持续性本质上是考察基金历史业绩是否对未来业绩有一定程度的揭示作用,其思想与有效市场假说相抵触,被视为金融市场的异常现象.本文对基金业绩持续性研究的三个主要问题--持续性是否存在、持续性的来源、持续性检验方法,做了较为全面的综述,并归纳整理了进一步的研究方向. 相似文献

Transition matrix techniques are used to relate the past and present performance of pension fund portfolios. In particular, funds are ranked to study the tendency of portfolios to remain in the same quartile of the ranking as they were in the previous period. For raw returns, funds in both of the top quartiles are found to be more likely to remain in the same quartile than would be expected by chance. This result can be taken as limited evidence for the consistency of performance. Similar systemic effects are observed on a risk-adjusted basis. There appears to be clear evidence that some fund managers can offer a degree of consistent good performance. 相似文献

We propose an alternative mutual fund performance index which addresses the benchmark problem and controls for economies of scale in managing mutual funds. We advance a new concept of 'return-cost' efficiency as another important element in evaluating portfolio management, in addition to the mean-variance efficiency concept. Our index based on a non-parametric estimation is shown to be similar to the Sharpe index with multiple slopes (or factors). We have shown that all fund categories, except income funds, have similar average efficiency scores after controlling for economies of scale. Most funds operate in increasing returns to scale and seem to be successful in holding mean-variance efficient portfolios, but unsuccessful in allocating transaction costs efficiently, evidenced by excessive turnovers and loads. 相似文献

本文利用数据包络分析法(DEA)对我国开放式基金2003~2008年的投资管理效率进行总体分析,发现我国开放式基金投资效率很低,基金风格、基金管理公司、规模大小、分红等都会影响其综合技术效率、纯技术效率与规模效率。进一步利用Malmquist生产率指数对其动态效率进行分析表明,开放式基金整体效率存在改善,主要来自于技术进步。 相似文献
