Using a comprehensive database on equity funds in Korea, we investigate the performance and performance persistence with investment style employing the Fama and French three-factor model and the Carhart four-factor model. The paper finds that most investment styles in Korea noticeably outperform the passive benchmarks. In addition, positive performance persistence is observed among funds investing in large-cap stocks and stocks of high past performance. Finally, outperformance and positive performance persistence of equity funds are still present in various ranking and postranking horizons. These empirical findings are in sharp contrast with results from earlier studies on markets in developed countries, such as the United States.  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

We examine Turkish fund portfolios and identify the role of international investments in their formation. We find that (1) Turkish funds hold a very small fraction of international assets during 1987-2008, (2) the weight of international equity in the funds with an international mandate is smaller than the total weight of domestic asset classes as of 2009, and (3) international stock holdings of Turkish portfolio managers show significant similarity, which can be explained by the fact that the managers tend to hold stocks with which they are familiar. We compare the performance of funds that have the international investment objective with benchmark portfolios and provide suggestions for more diverse funds in the Turkish fund industry.  相似文献

This paper evaluates the ability of US-based Asian mutual fund managers in coping with the 1997 Asian financial crisis. We find that the actively managed mutual funds under-perform with respect to the market portfolio by 1.71% in average monthly return. Such poor performance is caused by fund managers' relative weakness in country selection as well as in stock picking. Fund managers are also found to be more skillful in picking the correct market when the market is going up than going down. Our results are consistent with the literature that asset allocation in Asian mutual funds is a dominating factor relative to selectivity in explaining fund returns during the financial crisis. In addition, there exists a negative relation between asset allocation ability and selectivity of fund managers.  相似文献

基金在业绩排名压力下的泡沫资产配置行为会加剧市场波动、推升市场泡沫。本文基于事件研究法与固定效应模型研究了2013―2020年基金的重仓持股,发现:(1)基金在泡沫膨胀阶段显著超配了泡沫资产,而在泡沫破裂前后显著减配,展现了“泡沫骑乘者”的特征;(2)2015年前后,泡沫资产主要为小市值股票,2019―2020年,泡沫资产逐渐转为大市值“白马股”,且基金超配的程度显著提高,呈现抱团大盘白马股的特征;(3)排名前5%的赢家基金,以及1/3和1/10关键排名处的基金更激进地超配泡沫资产;(4)相邻排名基金的业绩差异越大,基金的泡沫资产配置行为越明显。综上表明,基金公司并不一定是天然的市场稳定器,监管层应密切关注业绩压力下基金超配泡沫资产的行为,投资者则应理性选择长期声誉较高的基金。  相似文献

Using a sample of Australian Multi-sector trusts we examine selectivity and market timing performance and extend the analysis to include the relatively new measure of volatility timing. This is of particular relevance to our data set, as high levels of volatility persistence are prevalent in Australia. In addition we consider the stability, asymmetry and seasonality of the various performance and risk measures. A survivorship adjustment procedure is also employed in order to assess the impact of survivorship on selectivity, market timing and volatility timing performance.  相似文献

基金投资风格的极端性与业绩研究   总被引:1,自引:0,他引:1  
本文首次从综合性视角考察基金投资风格的极端性与其业绩之间的关系。采用投资风格极端性指数和行业集中度作为投资风格的测度,研究发现投资风格的极端性与基金业绩成反比,即投资风格越极端,基金的收益越差。因此,我们建议基金经理在做出投资策略时,应当遵循稳健的投资风格与分散化投资,当发现自己的投资组合风险较大或有明显的行业偏重时,及时做出调整。对于风格极端的基金投资组合,应保持谨慎的态度。  相似文献

Jumps and Dynamic Asset Allocation   总被引:2,自引:0,他引:2  
This paper analyzes the optimal dynamic asset allocation problem in economies with infrequent events and where the investment opportunities are stochastic and predictable. Analytical approximations are obtained, with which a thorough comparative study is performed on the impacts of jumps upon the dynamic decision. The model is then calibrated to the U.S. equity market. The comparative analysis and the calibration exercise both show that jump risk not only makes the investor's allocation more conservative overall but also makes her dynamic portfolio rebalancing less dramatic over time.  相似文献

In this article, we evaluate the performance of mutual funds in China between 2006 and 2014. We first estimate time-varying abnormal returns of each mutual fund using an active peer benchmark-augmented factor pricing model. An index of riskiness is then estimated and used to calculate the augmented performance measure (APM). By construction, the APM separates the managerial premium of the fund from systematic risk premium, so it is better than the economic performance measure. The APM incorporates information beyond the first and second moments of the distribution of fund abnormal return; therefore, it is more informative than the Sharpe ratio.  相似文献

Numerous studies have examined the factors associated with allocation of corporate and government pension-plan assets. Yet to date there has been no attempt to identify the sponsor-related conditions that affect the percentage of U.S. private and public pension-fund assets invested in real estate. The purpose of this article is to examine various asset-and liability-matching hypotheses regarding pension-plan asset allocations. Models are specified for both corporate and government defined-benefit plans that relate the characteristics of each plan to the percentage allocated to real estate investments. Our results confirm the existence of a significant size effect for both corporate and government pension plans, although we find mean levels of real estate allocation to be much lower than those suggested in previous real estate allocation studies. The article, however, contains some anomalous findings. In particular, our findings suggest that pension-plan sponsors do not hedge their real estate risk. We also find that pension-plan sponsors do not invest in real estate, as theory might suggest, to minimize the noise level in their pension liabilities.  相似文献

王婧 《保险研究》2019,(5):44-54
中国第二代偿付能力监管制度体系(以下简称“偿二代”)执行以后,投资风险直接体现在资本要求上,资本充足率成为保险公司投资决策的重要约束。在此背景下,保险公司有必要建立整体经济资本预算框架,通过提高各类资产的边际资本回报率,提升公司股东价值。本文通过理论研究证明资本约束下保险公司最优大类资产配置的路径首先是进行负债风险匹配资产的管理,其次才是追求盈余资产收益最大化,同时,本文创新性提出了三阶段的数值求解方法,填补了国内文献以及保险公司实践中难以前置化资本约束得到大类资产配置数值解的研究空白。  相似文献

We examine the performance of U.K. unit trusts with international equity objectives between January 1985 and December 2000 using four international factor models. The international version of the Carhart (1997) model performs the best in explaining the cross-section of international stock returns. There is little evidence of superior performance by international trusts relative to the global models. We also find that the choice between a local and global version of the Carhart model has a significant impact on the relation between the investment sector of the trust and performance.JEL classification: G10, G12  相似文献

有关商业银行资产负债管理模型的研究表明,基于多阶段带简单补偿的资产负债随机模型适合现阶段中国商业银行的资产负债管理问题。本文建立了三大国有上市商业银行的简化资产负债管理模型,运用遗传算法进行运算求解。模型结果能反映商业银行资产配置的基本变化趋势;贷款配置比例始终大于债券投资比例,表明银行仍然立足于传统信贷业务;三大商业银行的最优资产配置略有差异。考虑到商业银行资产收益率以及存款负债流的不确定性,实证结果表明该模型对实际管理决策具有现实指导意义。  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

We analyse time-varying risk premia and the implications for portfolio choice. Using Markov Chain Monte Carlo (MCMC) methods, we estimate a multivariate regime-switching model for the Carhart (1997) four-factor model. We find two clearly separable regimes with different mean returns, volatilities, and correlations. In the High-Variance Regime, only value stocks deliver a good performance, whereas in the Low-Variance Regime, the market portfolio and momentum stocks promise high returns. Regime-switching induces investors to change their portfolio style over time depending on the investment horizon, the risk aversion, and the prevailing regime. Value investing seems to be a rational strategy in the High-Variance Regime, momentum investing in the Low-Variance Regime. An empirical out-of-sample backtest indicates that this switching strategy can be profitable, but the overall forecasting ability for the regime-switching model seems to be weak compared to the iid model.  相似文献

业绩排名、投资者选择和投资基金行为   总被引:7,自引:0,他引:7  
本文利用中国开放式基金数据,对基金业绩与未来资金流入的关系及投资基金之间的“竞赛假说”进行了检验。结果发现,基金业绩与未来资金流入存在显著的正相关关系。整体而言,中国投资基金行业不存在“竞赛假说”,但投资基金在年末业绩排名竞争中存在显著的竞赛特征,投资基金在年中排名竞争方面则未表现出明显的竞赛特征。  相似文献
