做市商交易制度相比竞价交易制度,在场外资本交易市场中具有价格发现和创造流动性等优势,国际上较成熟的场外交易市场大都选择了做市商交易制度。本文认为在我国低层次资本市场建设中,有必要引入做市商报价和竞价交易互为补充的混合交易制度,探索建立我国证券场外交易市场。  相似文献

交易制度包括竞价交易制度和做市商制度,恰当的交易制度能够帮助投资者发现均衡价格,从而保障证券市场的稳健运行.从国际实践来看,创业板市场发展初期普遍存在市场容量小、信息不对称现象突出等问题.需要通过做市商制度来保障其健康发展.但随着创业板的发展,技术与市场条件的变化使其更倾向于采用混合交易制度.随着法律制度与市场基础设施的完善,我国创业板已启动,从其发展初期的特征来看,符合引入做市商制度的相关要求,由于我国在竞价交易制度方面经验丰富,国际经验也证明竞价交易制度与做市商制度各有优势,我国创业板应建立混合交易制度.  相似文献

该文对竞价交易制度和做市商制度进行了比较,运用博弈论的方法对做市商的报价行为与中国证券市场庄家的坐庄投资行为进行了理论分析,为引入做市商遏制庄家坐庄的观点提供了理论支持;同时从庄家陷入的囚徒困境的角度阐述了中国证券市场引入做空机制的有效性,得到了在完善现有竞价交易制度的前提下,引入做市商角色有利于我国证券市场健康有效发展的结论.  相似文献

期权市场具有套期保值、价格发现、风险控制等功能,我国作为一个发展中国家,目前暂时还没有交易所期权产品,但正是这种后发优势给我国期权发展带来了更多的选择空间。要促进我国期权市场的健康持续发展,在期权运行的高效运转和稳健发展中寻求平衡,期权市场在竞价交易中要引入做市商制度,通过做市商为期权交易提供连续双向报价,促进交易的活跃、增加市场的流动性。  相似文献

做市商制度是国际外汇市场上主要交易制度之一。做市商作为价格形成的中介与核心,不断进行双向报价,以自有资金与投资者进行交易,并通过买卖价差实现一定的利润,为市场提供流动性。2005年5月,我国外汇交易中心推出外币做市商制度,中国银行等九家中外银行成为首批做市商,外币买卖包括欧元/美元、英镑/美元等八个货币对的即期交易。2006年1月,我国银行间即期外汇市场推出美元/人民币做市商制度和引入询价交易方式,并改进人民币汇率中间价形成方式。做市商制度的推出对于我国外汇体制改革有着重要的意义。此前中国人民银行是外汇市场中人民币对外币交易的唯一做市商,在美元/人民币做市商制度推出后,由中外银行组成的做市商成为人民币汇率形成的市场力量,有利于更好地发现人民币的市场汇率水平,为进一步的汇改提供参照。引入做市商制度和询价交易方式后,银行间外汇市场交易主体既可选择双边授信、双边清算的方式进行询价交易,也可选择集中授信、集中竞价的方式进行交易。对于外汇市场做市商制度的研究,国内的相关资料不多,且偏重于宏观层面的讨论。本文基于市场微观结构视角,分析外汇市场做市商的收益与成本,研究做市商的日内交易行为以及指令流的传递过程,并从提高做市商...  相似文献

做市商制度不同于竞价交易制度,其显著特点是做市商同时进行显性的买卖双向报价并按其主动报出的价格进行交易。做市商在报价时必须考虑自己的做市成本,特别是存货成本和信息成本,从而便产生了理论上的存货定模型和信息定价模型。随着证券市场的不断发展和完善,我国也势必推行做市商制度,因此有必要研究通过各种途径降低做市商的做市成本,以维持正常报价和整个证券市场的秩序化。  相似文献

银行间外币买卖业务采用了做市商报价驱动的竞价交易模式,这是我国金融市场建设中在交易制度安排上的全新尝试。它将推动国内外汇市场向更有效率的市场发展,实现市场参与者的“多赢”,并有助于完善人民币汇率形成机制,失去我国金融市场走向国际化。  相似文献

证券市场有竞价和做市商两种典型的交易组织方式。该文以NASDAQ市场为例,从做市商制度对证券市场基本属性的影响来看,做市商制度相对于竞价市场有一定优越性,并对该项制度的运作功能作了必要的澄清。在此基础上探讨了我国二板市场推行做市商制定的理由、实施的可行性和必须注意的问题。  相似文献

2006年1月,银行间外汇市场正式引入人民币对外汇交易做市商制度。其后,由做市商控制的询价交易制度凭其成本优势(同笔交易费用仅为竞价交易的1/30),交易方式灵活(可自选交割日、对话成交)而迅速受到市场青睐,从而取代旧有的竞价交易方式成为市场主要交易方式。做市商制度启动后,从规则上看,央行不再直接参与询价市场交易,做市商取而代之成为市场主导力量。做市商作为央行的代理人,在承担提供流动性义务的同时,也获得了人民币的定价权。那么,这样的权利和义务,会给做市商带来什么呢?  相似文献

Using data on Canadian bond futures, we examine how high-frequency traders (HFTs) interact with institutions building large positions. In contrast to recent findings, we find HFTs in the data act as small-sized liquidity suppliers, and we reject the hypothesis that they engage in back running, a predatory trading strategy. Using a quasi-experiment in November 2011, in which a number of HFTs started trading the bond future, we run a difference-in-differences event study and find more competition among HFTs improves implementation shortfall, effective spreads, and short-term price impacts for institutional trading in Canadian bond futures.  相似文献

This paper is a continuous time version of Holden and Subrahmanyam (Economics Letters 44 (1994) 181). The paper extends Kyle (Econometrica 53 (1985) 1315) by introducing risk aversion on the side of the monopolist informed trader and allows for the liquidity traders instantaneous demand to depend on cost of trading, as well as on the risk of the stock. The main result of the paper is that, in equilibrium, the price pressure decreases with time regardless of the elasticity of the liquidity demand function.  相似文献

证券市场上的高频交易模式大体上分为四类:订单拆分策略、做市交易策略、定量化交易策略和其他策略。研究发现:(1)高频交易降低了买卖价差,提高了市场流动性,而并没有增加市场波动率,甚至反而可能降低了市场波动率;(2)没有发现高频交易者存在系统性抢单行为(并不排除有特定高频交易者存在此类行为);(3)学术研究认为高频交易有导致市场风险的可能性,但是事件调查大多认为高频交易不是引发市场风险的罪魁祸首。本文认为,对高频交易的监管应该注重抓住重点区别对待,以维护公平、透明、高效的市场秩序。  相似文献

In this paper we empirically analyze whether the degree of trader anonymity is related to the probability of information-based trading. We use data from the German stock market where non-anonymous traditional floor based exchanges co-exist with an anonymous computerized trading system. We use an extended version of the Easley et al. (J. Finance 51 (1996) 1405) model that allows for simultaneous estimation for two parallel markets. We find that the probability of informed trading is significantly lower in the floor based trading system. We further document that the size of the spread and the adverse selection component are positively related to the estimated probabilities of information-based trading.  相似文献

This paper evaluates the welfare implications of front-runningby mutual fund managers. It extends the model of Kyle (1985)to a situation in which the insider with fundamentals-informationcompetes against an insider with trade-information and in whichnoise trading is endogenized. Noise traders are small investorstrading through mutual funds to hedge non-tradable or illiquidassets. The insider with trade-information is one of the fundmanagers. We find that her front-running activity reduces theliquidity costs of her customers, but it also reduces theirhedging benefits. As a result, the customers of the front-runningmanager may be worse off and place smaller orders. The oppositeis true, however, for those investors who are not subject tofront-running. In aggregate, front-running has either no orpositive consequences for welfare. JEL Classification. G14,G23.  相似文献

This paper develops empirical evidence on the viability of a form of volatility trading known as “dispersion trading.” The results shed light on the efficiency with which U.S. options markets price volatility.Using end-of-day implied volatilities extracted from equity option prices for the stocks that comprise the S&P 500, the implied volatility of the S&P 500 is computed using a modification of the Markowitz variance equation. This Markowitz-implied volatility is then compared to the implied volatility of the S&P 500 extracted directly from index options on the S&P 500. These contemporaneous measures of implied volatility are then examined for exploitable discrepancies both with and without transaction costs. The study covers the period October 31, 2005 through November 1, 2007.It is shown that, from a trader's perspective, index option implied volatility tended to be more often “rich” and component volatilities tended to be more often “cheap.” Nevertheless, there were times when the opposite was true; suggesting that potential dispersion trades can run in either direction.  相似文献

黑池交易系统(Dark Pools)是美国近年发展较快的非公开交易平台, 其信息透明度较低,可提供匿名交易的服务,并由此实现信息的非公开传递。通过扩展后验信念收敛速率的模型来描述不同交易透明度下场外市场的信息显示速率, 发现私人信息与公共信息共存有利于信息更快地显示,因而私人信息渠道与公共信息渠道共存有利于提升信息效率,由此解释了非公开交易平台的价值,也为我国场外市场的分层发展提供可行建议.  相似文献

This study utilized high frequency transactions data to analyze the trade size preference of informed traders in Indian equity markets. It is observed that informed traders at an aggregate level adopt stealth trading strategy, wherein they prefer medium sized trades over large sized trades in order to camouflage their private information. However, the stealth trading behavior varies across stocks, wherein informed traders prefer more large sized trades on firms that are part of an index compared to non-index firms. Trading behavior also varies across other market conditions. It has been noted that informed traders prefer large sized trades during periods of high market thickness, negative returns, and low volatility. This study also provides a rationale for such varied behavior of informed traders.  相似文献
