高频交易是资本市场上金融科技迅速发展的产物,是一种采用托管等低延时通信技术,通过高速信息处理,运用多个算法程序实施日内频繁交易的自动交易系统。尽管高频交易具有提供市场流动性、加深市场深度的积极意义,但也存在放大市场波动、为交易而交易且容易导致滥用市场交易优势的操纵行为。比较目前欧美对高频交易的监管实践,幌骗、试单、扰乱交易行为以及滥用市场成为高频交易操纵市场的主要手段。立足于我国现实,对集中于期货市场的高频交易应加强监管,完善透明、及时、公开的市场报价机制,明确涉及高频交易操纵行为的判断指标体系。 相似文献

高频交易模式作为一种新兴的交易模式,代表着未来交易的发展方向。短短几年内占据了期货市场的巨大份额,改变了传统的交易模式。近年来,我国证券市场上也有了较多的交易者进行量化交易。高频交易在为市场创造超常流动性并平滑证券价格的同时,也对市场交易秩序产生消极影响。通过对美股“5.6闪电崩盘”过程的梳理,总结分析美国证券市场的监管措施,从技术层面提出了加强我国证券市场监管对策建议。 相似文献

高频交易对证券市场的影响及监管对策 总被引:4,自引:0,他引:4
高频交易在欧美发达证券市场已经非常活跃,并促进了市场的有效性,但对其仍然褒贬不一。高频交易固然存在一些风险,但是市场的需求推动其不断获得交易商的青睐。虽然我国目前证券市场状况限制了高频交易的发展,但是,未来的市场竞争必然要求监管部门改革证券市场交易制度,放开对高频交易的管制。因此,借鉴欧美发达国家的监管经验,制定监管的法律标准,引导高频交易对证券市场发挥积极作用。 相似文献

高频量化交易是我国资本市场数字化发展的表现形式之一,会引发新的市场风险。证券交易印花税作为在我国资本市场发挥金融调控职能的“金融交易税”,对高频量化交易应扬长避短,与时俱进防范新型风险,促进我国资本市场健康稳定发展。因此,本文提出证券交易印花税的改革方向:针对高频量化交易快速高比例撤改单特点,对超出一定限额的高速撤改订单额外征收证券交易印花税,从而实现高频量化交易与其他交易的差别税率设定。改革时机需以准确测度高频量化交易规模与市场影响为前提。税收收入用途明确及监管措施有效配合是保障改革目标实现的重要举措。 相似文献

本文着眼于澳大利亚在治理金融衍生品市场内幕交易中积累的丰富经验,针对一个崭新的前瞻性课题,即金融衍生品市场的内幕交易问题展开研究。作者认为,由于内幕交易与信息非对称性之间存在的内在冲突,实际上反内幕交易法规很难有效地阻止金融衍生品的内幕交易行为,过于复杂的反内幕交易法规会对市场产生一些负面影响,而放松内幕交易监管这一新思维将对市场的良性发展更为有益,应该让市场来决定内幕交易行为的“存亡”。但目前最为现实、温和的选择仍然是修改现行反内幕交易法,以维护市场的公平性和有效性。最后,笔者对如何缓解中国目前内幕交易猖獗的现状提出建议。 相似文献

Liquidity trading is an important component of market microstructure models. In most cases, its role is primarily to ensure existence of equilibrium and therefore that trading occurs among asymmetrically informed agents. While most market microstructure models allege that agents trade based upon rational expectations, the rationality of the type of liquidity trading assumed in these models remains to be verified. Specifically, liquidity traders are often assumed to submit price-inelastic orders for reasons exogenous to the model at hand. But whether price-inelastic trading is consistent with rational utility maximizing behavior remains to be shown. 相似文献

This study investigates the effects of investor trading behavior and investor sentiment on futures market return. We find that the spot investor trading behavior, futures investor trading behavior, spot market sentiment, and futures market sentiment all have positive effects on daily futures returns in Chinese financial market. More importantly, we show that the effect of (spot) futures investor trading behavior has better explanatory power than (spot) futures market sentiment on futures returns. Further supporting our results, high investor trading behavior and high investor sentiment strengthen the positive relation between sentiment-returns and behavior-returns. 相似文献

Abstract: This study investigates how limit orders affect liquidity in a purely order-driven futures market. Additionally, the possible asymmetric relationship between market depth and transitory volatility in bull and bear markets and the effect of institutional trading on liquidity provision behavior are examined as well. The empirical results demonstrate that subsequent market depth increases as transient volatility increases in bull markets. Market depth exhibits significantly positive relationship to subsequent transient volatility in bull markets. Additionally, although trading volume positively influences transient volatility in bull markets, no such relationship exists in bear markets. Liquidity provision decreases when institutional trading activity intensifies during bear markets. Thus, liquidity provision for limit orders differs between bull and bear markets. 相似文献

动量交易策略指的是事先针对股票收益及交易量设定过滤规则,一旦股票收益或者股票收益和交易量同时满足过滤规则就买入或卖出股票的交易策略。动量交易策略的理论基础是行为金融学。国外投资者已经成功地在实践中应用了该策略。我国股票市场是否存在动量效应,还未形成统一的结论。在总结国内外学者研究方法的基础上,利用目前可用的数据,对我国股票市场在中期条件下动量交易策略的适用性进行了实证研究。但得出的结论并不支持存在动量效应。 相似文献

Many previous studies on insider trading are based ondata in the U.S. capital market and conclude thatinsiders can earn abnormal profits. This paperexamines abnormal price performance associated withinsider trading in the Hong Kong stock market. We findthat abnormal profits associated with insider tradingare all concentrated on small firms. Trading volumedoes matter in determining the magnitude of thoseabnormal profits. Our results show that insiders ofmedium-sized and large firms do not earn abnormalprofits. Finally, it is found that outsiders who mimicthe information of insider trades associated withmedium-sized and large firms cannot earn abnormalprofits. 相似文献

It is discovered that the CUSUM techniques often used in the manufacturing industry can be adapted to yield a trading strategy in the financial market. The familiar filter trading strategy in finance is found to be a particular case of CUSUM procedures. A more general form of the CUSUM techniques will yield new trading strategies which have intuitive appeals. Trading characteristics of such strategies will be investigated using CUSUM techniques. 相似文献
