我国《证券法》对信用交易法律责任规制的阙如

我国2005年修订的《证券法》引入了信用交易制度,但对信用交易的法律责任的规定只有第205条,规定得简单、笼统、可操作性不强,并且法律责任形式单一。因此,应该完善我国的证券信用交易法律责任制度,确保我国信用交易制度的健康发展和社会公平正义的实现。

证券信用交易:海外规制经验与中国制度建设

证券信用交易是海外证券市场普遍、成熟的一种交易制度.由于证券信用交易的发展有极强的路径依赖,不同国家(地区)的文化、法律背景的差异、政府监管理念的不同、市场发达程度的不一,其交易模式与监管模式的选择也各不相同.中国的证券信用交易规制是在海外发达国家(地区)的立法和实践经验基础上制定的,作为资本市场一项典型基础制度创新,证券信用交易制度的建设,除需移植海外发达国家(地区)的制度精髓外,还应根据我国证券市场的特色,进行本土化选择与创新.     

法律视角下中国证券信用交易制度的构建

我国目前对"证券信用交易"的认识在理论和实践中存在一定的混乱.迄今为止,在中国的证券市场上,并没有建立起证券信用交易制度,法律也严格禁止证券商向客户融资融券.但是,证券信用交易却是证券市场比较规范的国家或地区的通行做法,也成为证券市场自然而不可缺少的一个部分.近年来,随着中国证券市场向纵深发展和加入WTO与国际接轨的需要,中国对是否禁止证券信用交易态度已有所改变,本文从法律的角度,对中国证券信用交易制度的构建提出相关建议.     

我国证券信用交易模式选择及制度规范研究

通过分析比较海外证券信用交易模式,结合中国证券市场的实际,对国内信用交易的模式选择和制度安排做了有益的预测研究,其中论证了过渡模式中实施证券公司许可证制度的可行性,以期对信用交易的业务开展有所裨益。同时要想充分发挥其积极的作用,还必须从风险控制机制、转融通机制和监管这几个方面完善信用交易制度,从而加快我国证券市场的发展步伐。

关于建立股票信用交易制度的思考

建立股票信用交易制度对投资者、证券公司、商业银行以及证券市场的长远发展都具有积极作用,而且由于信用交易以现货交易为原则,这种交易制度的实行在技术上也不存在任何实质性障碍.对信用交易的风险和投机性应当客观、正确地加以看待,信用交易的缺陷不应成为建立信用交易制度的根本障碍.     

浅析证券法修订的积极意义

随着我国资本市场改革步伐的加快,资本市场的发展已具备了实现重要突破的基础。现行的证券法只是一部阶段性的证券法律,已不适应我国目前所处的国内外政治经济环境。《证券法》的修订,改变了证券公司的业务链条、业务流和现实的业务量,本质上是对我国资本市场有价证券的发行交易、清算以及监管制度的调整。担当起其在我国创新型国家建设中应负的历史使命,加快了我国创新型国家战略目标的实现。

Does trade size restriction affect trading behavior? Evidence from Indian single stock futures market

Algorithmic traders use their advantage of speed to execute a large number of small-sized trades in a very short time. In the presence of a minimum trading unit (MTU) restriction, they are forced to trade at the smallest possible sizes, often restricted by the MTU. Using a novel data set of single stock futures market obtained from the National Stock Exchange of India, we show that the MTU restriction acts as a binding constraint for traders while optimizing trade sizes. Contrary to expectation, we find weak evidence that liquidity is positively impacted by the contract size revision.     

Trading Portfolios Electronically – An Experimental Approach

This paper focuses on a simple axiom – investors prefer to hold diversified combinations of assets. Arguing that pooling vehicles like mutual funds offer approximate solutions, we propose a portfolio trading mechanism that allows individuals to trade diverse combinations of assets through a single order. Given the complexity of the market mechanism, we construct a prototype of this trading system and test it through a series of laboratory experiments with student subjects. We address the quality of the price discovery process, quality of allocations, and efficiency of the market mechanism. Results from a set of laboratory experiments indicate that the performance of such systems is sensitive to design aspects as well as relative experience of participants.

中国碳试点市场集中交易行为的理论研究

通过构建一个代表性控排企业跨期决策理论模型,分析碳配额交易企业在履约日与非履约日的最优交易量。均衡结果显示,企业在非履约日的最优交易量与其自身的风险规避系数、市场流动性提供者的风险规避系数、履约日随机碳需求的标准差成正比,而与企业的碳产出效率成反比。在此基础上,探讨了中国碳交易试点市场上履约日附近交易量巨大,而非履约日交易量稀少的原因,并提出相关政策建议,以帮助实现我国碳市场交易量的平滑及整体市场效率的提升。     

Is options trading informed? Evidence from credit rating change announcements

Using a sample of proactive credit rating changes, this study examines the information content of options trading before news events. Pre-event informed options trading predicts cumulative abnormal returns around credit rating change announcements. The predictability of options trading is more pronounced before announcements of more severe and surprising rating changes. Moreover, the information content of pre-event options trading is greater when the pre-event underlying stock market is less informational, when the options market is more liquid, and in the post–regulation fair disclosure period. Overall results are consistent with informed options trading before credit rating change announcements.     

会计信息披露实际与内幕交易——基于年报首季披露时差与异常超额交易量的实证研究

Considering the cost of capital, systematic risk and the probability of being monitored and punished, informed traders are most likely to conduct informed trading at the small time gap between the disclosure of annual report of year t and 1^st quarter reports of year t+1 because the gap is the best and safest time for informed trading. Meanwhile, due to the high cost and risks of informed trading, traders need huge trading volumes to gain abnormal returns. Based on these characteristics of informed trading, a research sample and a control sample are found for this paper. The former refers to companies with loss annual report in year t and profit-making 1^st quarter financial report in year t+1 in tandem. The latter refers to companies announced loss in the previous year and and profit-making 1^st quarter financial report in year t+1 simultaneously or companies with loss annual report in the year t and loss 1^st quarter financial report in year t+1 in tandem. Results confirm the existence of informed trading by measuring “extra abnormal trading volume”. Therefore, authors suggest that a good disclosure policy should not only consider the timeliness and accuracy of the financial reports, but also the overall information disclosure process to prevent potential informed trading.

Investor behavior and volatility of futures market: A theory and empirical study based on the OLG model

Investor trading behaviors are always an important issue in behavioral finance and market supervision. This study examines the relationship between investor behavior and future market volatility. We first introduce a two-period OLG model into the futures market, and develop an investor behavior model based on future contract price. We then extend the model to two scenarios: complete and incomplete information. We provide the equilibrium solution, and develop two hypotheses, which are tested with cuprum tick data in Shanghai Futures Exchange (SHFE). Empirical results show that the two-period OLG model for future market is consistent with the market situation in China. More specifically, investors with sufficient information such as institutional investors usually adopt the contrarian trading strategy, whereas investors with insufficient information, e.g., individual investors, usually adopt the momentum trading strategy. These findings reveal that investor behaviors in the Chinese futures market are different from those of in the Chinese stock market.     

The cross-predictability of industry returns in international financial markets

This article finds evidence of return cross-predictability among trading partners in international financial markets. We show that the predictability of international customers dominates the predictability of domestic customers, and the predictability of international intra-industry customers dominates the predictability of international inter-industry customers. This return cross-predictability decreases with two country characteristics: financial sophistication and size.     

A rare move: The effects of switching from a closing call auction to a continuous trading

This study investigates the effects of switching to a closing continuous trading (CCT) on market quality, while considering the trading behaviors of different types of traders. Investors become more patient in the period preceding the last trading phase, which reduces the bid–ask spread (BAS) in that period. We find an increase in the BAS and volatility during the last trading phase, due to diminishing investor patience. Market volatility and the closing pricing errors relate positively to the trading activities of foreign institutional investors. Overall, the introduction of the CCT worsens the market quality before the closing.
