Market inefficiencies surrounding energy announcements

We use sequential energy inventory announcements to shed new light on the informational efficiency of financial markets. Our findings provide clear evidence of inefficiency in crude oil futures and stock markets. This inefficiency can be exploited by sophisticated traders. We examine the effect of market liquidity on the efficient incorporation of information in this setting. We also construct a predictor that can predict inventory surprises and preannouncement returns in-sample and out-of-sample. Finally, we develop a combination forecast that can be used as a proxy for market expectations of oil inventory announcements.     

机构投资者与金融衍生品市场

机构投资者对金融衍生品市场的发展和成熟起关键作用。在分析金融衍生品市场发展现状的基础上 ,对机构投资者参与金融衍生品交易的行为和动因进行了研究。金融衍生品市场演变的一个重要趋势是交易机构的高度集中 ,但机构集中可能是金融衍生品市场区别于其它市场的固有特征。我国发展金融衍生品市场需重视培育机构投资者 ,除了构建适宜的法律环境、采取积极的风险管理人才储备策略外 ,应认识银行在金融衍生品市场中的重要作用

中国股市收益与经济增长背离现象的协整性检验

近年来很多专家学者已经注意到了中国股市收益与经济增长相背离的现象,并将这种现象称之为“股经背离”。应用计量经济学中的协整理论,对我国股市收益与经济增长的关系进行实证分析,结果表明,代表虚拟经济的股市和代表实体经济的经济增长之间并不具有长期的均衡关系,从而用计量经济学的方法进一步证实了“股经背离”现象的存在。     

中国股市政策市研究述评

文章对政策市的有关研究进行了归纳和梳理,将主要的研究概括为股市政策与政策市,政策市产生原因,不同属性政策的定性分析,政策市运行机制,政策市影响减弱分析,政策市退出市场等方面,揭示出政策市的最大问题是股市政策的行政化,政策市退出股市必须以增强投资者选择权为基础,而这需要经历一个漫长的过程。

An Analysis of Stock Market Response to the IOC's Commercial Partnership: The Case of the TOP Partnership Program

The purpose of this study was to investigate the empirical properties of stock market response. The financial impact of corporate sponsorship is reflected in the market value of a firm's stock price, which is measured by comparing the abnormal stock return between the preevent window (250 trading days) and the 14 trading days of the event period. Computations of ARs, CARs, and other test statistics were based on the event study model and were carried out using the SAS 9.2 software. For the preevent windows (t = ?3, t = ?1), there were statistically significant positive ARs and 80% of the TOP sponsors showed positive ARs in the overall duration of the Olympic Games. The overall CARs during the event period (t = ?3 through t = +10) indicates marginally positive returns for the event.     

金融中介对技术创新促进作用的实证分析——基于长三角城市群的面板数据研究

以证券市场为代表的金融市场体系和以银行为代表的金融中介体系都通过提供资金支持、信息与风险管理、完善公司治理等各种渠道促进了技术创新。既有研究主要强调前者对技术创新的促进作用,然而,金融中介在某些方面更具优势,发挥着不可替代的重要作用。对长三角地区数据样本的面板数据实证分析结果证明了金融中介对技术创新,特别是原创型发明的推动作用。实证结果还表明金融业的改革创新对其他行业有较强的示范效应。

How Have the Emerging Stock Exchanges in Africa Responded to Market Reforms?

Abstract

In this paper, we focus on how the stock markets in Africa have responded to the reform process. We identify three main types of reforms implemented in these markets since the 1990s, namely revitalization of the regulatory framework, modernization of trading systems, and relaxation of restrictions on foreign investors. We invoke market microstructure theory to hypothesize the expected response of the markets in terms of efficiency and volatility to the three types of reforms. Econometric methods are applied to test the hypotheses on a sample of ten stock exchanges, for the period 1988:01-1999:12. The evidence generally suggests that there are benefits of investments to improve market microstructure. For example, a comparative analysis across the sample demonstrates that markets with advanced trading technology, tight regulatory system and relaxed foreign investors' participation show greater efficiency and lower market volatility. Although direction of causality between efficiency and volatility varies across the markets, in general, we infer that reforms, which reduce volatility, reap higher efficiency. However, in some markets, the effects of the reforms are too recent to show any clear response pattern.     

论金融产品的对内开放

金融产品是金融市场得以存在和发展的基础,是金融机构经营的基本对象,也是各类企业外源性融资的基本载体.长期来,在计划机制的影响下,政府部门主要通过对金融产品的种类、规模、价格和交易等四个环节实现对金融产品的管制,给金融发展造成一系列不良后果.强调金融产品的对内开放,就是要放松或取消政府部门对金融产品的品种、数量、价格和交易等方面的管制,变金融产品的行政性形成机制为市场化形成机制.     

西方金融市场效率理论发展述评

金融市场效率是现代金融学的理论核心,也是学术界长期以来关注的一个重要问题.本文从六个方面对西方有关金融市场效率的研究成果进行了概述:金融市场效率的内涵、基本价值分析的观点、非对称信息和交易费用与金融市场效率、行为金融学与主流金融学的分歧、分形市场假设与混沌理论的应用、动态视角下的金融市场效率.     

金融市场服务特征的营销学研究

金融市场的服务特征主要包括金融服务的特征、金融服务企业的服务特征、金融服务的顾客特征和金融服务市场的供求关系特征。我国现实金融市场正在由卖方市场向买方市场过渡,一些主要市场结构部分已呈买方市场特征,但金融服务企业界和金融理论界还是卖方思维和卖方经营理念,中国金融市场的营销理念与营销存在着非战略性、战术性、片断性缺陷。中国金融体制和机制的改革必须与金融服务企业营销的竞争能力、盈利能力进行有机整合和配套。

Index options open interest and stock market returns

This study finds that the growth of index options open interest has a significant relation with future stock market returns. We propose a theoretical model that considers hedgers and informed traders in the options market and suggests that hedgers fully utilize options according to their expectations of future stock returns. The empirical results show that the growth of out-of-the-money call options open interest is significantly related with future stock market returns. These findings provide supporting evidence for our theoretical model.     

Adaptive Market Hypothesis: Evidence from the Ghanaian Stock Market

This study examines the return predictability of two indices – the GSEALSH index and the GSEFSII index on the Ghana stock market. We compare results from analyzing the return series between January 4, 2011 and August 28, 2015 using the generalized spectral test, the automatic portmanteau Box-Pierce test and the wild-bootstrapped automatic variance ratio test. A rolling window approach is used to track whether returns are predictable or not through time. It was observed that the GSEALSH index was more highly predictable than the GSEFSII index in all the three tests. The results obtained are consistent with the Adaptive Market Hypothesis.     

Islamic legal methodologies and Shariah screening standards: Application in the Indonesian stock market

This article provides a framework for applying the principles of Islamic legal methodology to determine the optimal Shariah screening standards for Islamic equity markets. It is argued that using maslahah mursalah (unrestricted benefit) is an appropriate method for identifying appropriate financial standards and its principles stipulate that the benchmark that yields the best economic returns to investors should be chosen. The methodological framework is applied to the Indonesia equity market where the economic implications of the Islamic stock screening standards of the Indonesian Islamic Shariah Stock Index and four global indices are assessed. Portfolios are constructed by applying Islamic stock screening standards for each of the indices by using data on 377 stocks listed in the Indonesian stock market for 5 years. The performances measured by the Sharpe ratio, Treynor index, and Jensen alpha reveal that the Dow Jones Islamic Index screening criteria performs the best. Based on the method of maslahah mursalah, the article recommends using the screening standard of this index in the Indonesian stock market to maximize benefits to investors. While the approach used in this article is applied to Islamic equity markets, the methodological framework can also be used for other similar cases in Islamic finance.
