明星基金溢价效应:“高技术”还是“好运气”?

本文研究我国股票型、偏股型开放式基金的评级与未来业绩的关系。根据晨星公司的基金评级数据,每月构造1星级至5星级的基金投资组合,并采用Carhart四因子模型对组合收益进行风险调整,研究发现5星级基金每年能获得2%的超额收益率,5星级与1星级基金的套利组合年超额收益为6%。此外,采用自助法对超额收益率的进一步检验,本文发现,明星基金溢价与基金经理的选股能力无关,与基金经理的好运气有关。     

基于四因素模型的我国混合型开放式基金的投资绩效研究

本文通过四因素模型对我国市场上混合型开放式基金的投资绩效进行了实证研究和分析。研究表明,我国混合型开放式基金并没有获得显著的较高的超额收益率;在投资策略的选择上较为一致的选择了高贝塔、中小盘股、价值型策略,而在动量收益股票抑或反转收益股票的选择上并不明显。

分级基金投资价值与套利策略实证研究

分级基金在设计上借鉴了结构化产品的分级理念,通过对基金净资产的分解,将基金份额分成具有不同风险收益特征的子份额,以满足投资者差异化的投资需求。本文将从结构设计和条款特征等方面对分级基金的投资价值进行全面解析,实证研究分级基金折溢价、杠杆、折算套利机制与机会,并通过模拟交易在真实环境下测试套利策略的运行情况。实证研究发现,目前市场中较为活跃的融资型分级基金大部分存在溢价交易,但由于溢价套利涉及到的相关交易成本较高,加上套利过程中母基金净值波动风险并不能完全通过股指期货进行对冲,因此高频套利的alpha收益并不显著,且净值回撤较大。另一方面,实证发现通过预测上折而建立的B份额事件套利单次收益高达30%左右,鉴于目前市场中有相当部分的分级基金处于潜在的上折触发期,建议重点关注上折套利机会。     

我国开放式股票型基金窗饰效应研究

以开放式股票型基金为研究对象实证研究我国基金市场的窗饰效应。首先,初步考察基金对股票的买卖倾向,发现基金在报告期末更加倾向于买进盈利股票,而卖出亏损股票的行为则不明显。之后构建一个＂买入-持有＂投资策略,比较该策略收益与基金实际收益,发现前者能够获得2.38%的平均超额收益,证明基金在报表中公布的投资组合与其平时表现存在显著差异,剔除其他一些可能导致基金投资组合调整的因素后,证明我国开放式股票型基金存在显著的窗饰效应,且成长型基金以及之前业绩较差、股票投资换手率较高的基金更可能出现窗饰效应。     

我国开放式基金绩效归属分析的实证研究

通过对基金绩效的分解以及对证券选择能力和市场状况把握能力进行的分析与评价发现,基金组合超额收益率由选择收益率与风险收益率组成,从而也揭示了基金超额收益的来源.这一评价工作有利于保护基金投资者利益,促进我国证券投资基金业的健康发展.     

开放式基金锚定启发式偏差对其绩效的影响——基于行业超额收益率的视角

本文利用最小二乘法对我国开放式基金的投资看涨情绪变动指标与行业超额收益率的相关关系进行了检验,考察开放式基金作为一个整体在各个行业上是否存在锚定启发式偏差,并进一步设计指标衡量单只开放式基金的锚定启发式偏差程度,利用BB动态面板模型考察了锚定启发式偏差对基金绩效的影响,发现基于行业当期超额收益率的锚定启发式偏差显著利于提高投资绩效,而基于行业历史超额收益率的反转启发式偏差对投资绩效的影响不大.     

我国开放式基金赎回行为影响因素研究——基于动态面板数据模型

开放式基金赎回行为对其发展和存续具有重要的影响,文章通过研究基金短期净值增长率、累计净值增长率,基金规模、债券指数收益率等变量对净赎回率的影响,发现基金的累计净值增长率与净赎回率正相关,出现“赎回异象”,但是市场依然具有追逐短期业绩的行为,净赎回率的滞后一期与净赎回率负相关,反映投资者的特殊心态。基金管理人应该稳定基金业绩、合理控制基金规模以获得长期稳定发展。     

开放式基金业绩评价综述（续）

三．实践中的业绩评价体系 1．传统财务指标 基金的传统财务指标主要是考察基金单位净资产、净值收益率等。这些指标简单直观、易于比较，但只注意到了基金的收益，没有对基金组合的风险进行量化分析。     

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.     

The development of the group accounts disclosure system in Japan

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

The deliberation around accounting techniques: accounting for depreciation and foreign exchange in an Indian jute company, 1870-1900

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.     

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.
