This article examines the impact of MiFID II on European equity market liquidity. MiFID II eliminated broker crossing networks, introduced caps on dark trading, and brought about new types of venues. The authors investigate the changes in the market in the lead-up to the January 3, 2018, implementation date and the early evidence supporting the expected liquidity shift toward block networks, periodic auctions, and systematic internalizers. Although all signs indicate limited change for end-investors, the delay in implementation of the double-volume caps means it is too early to fully assess the impact on trading costs.
本文考察了MiFID II对欧洲股票市场流动性的影响。MiFID II消除了经纪人交叉网络,对暗交易设定了上限,并带来了新的交易场所。作者调查了2018年1月3日实施日期之前市场的变化,以及支持预期流动性向区块网络、定期拍卖和系统内部化转移的早期证据。尽管所有迹象都表明,对终端投资者来说变化有限,但推迟实施两倍成交量上限意味着,全面评估对交易成本的影响还为时过早。

Dave BliDe Publisher The Summer issue of the journal begins with an examination by Carlens and Higgins of the impact of MiFID II on European equity market liquidity. They investigate the changes in the market in the lead-up to the January 3, 2018 implementation date and the early evidence supporting the expected liquidity shift toward block networks, periodic auctions, and systematic internalizers. In August 2012, the New York Stock Exchange (NYSE) launched the Retail Liquidity Program (RLP). The RLP enables market makers to quote dark (nondisplayed) limit orders that can be filled only by market orders that originate from retail traders. Garriott and Walton study the informational and market-quality impacts of segmentation using Trade and Quote (TAQ) data from the NYSE. They analyze the mechanism by which segmentation affects market quality by computing the information share of each component of the order f low using the techniques of Hasbrouck (The Journal of Finance, 1991). Next, Cole, Van Ness, and Van Ness study municipal bond market activity before, during, and after natural disasters (tornadoes, wildfires, and hurricanes/tropical storms). Using a sample of municipal bond trades from 2010 to 2013, they find that natural disasters inf luence municipal bond trading. They also determine that linkages exist between the bonds affected by natural disasters and related bonds. To continue, Kakushadze and Yu provide an explicit formulaic algorithm and source code for building long-only benchmark portfolios and then using these benchmarks in long-only market outperformance strategies. They use a multifactor risk model (which utilizes multilevel industry classification or clustering) specifically tailored to long-only benchmark portfolios to compute their weights, which are explicitly positive in their construction. To conclude this issue, Graf Plessen and Bemporad present a simple method for a posteriori (historical) multivariate, multistage optimal trading under transaction costs and a diversification constraint. The developed methods are based on efficient graph generation and consequent graph search and are evaluated quantitatively on real-world data. The fundamental motivation of this work is preparatory labeling of financial time-series data for supervised machine learning. As always, we welcome your submissions.

该杂志的夏季期以Carlens和Higgins对MiFID II对欧洲股票市场流动性的影响的研究开始。他们调查了2018年1月3日实施日期之前市场的变化,以及支持预期流动性向区块网络、定期拍卖和系统内部化转移的早期证据。2012年8月,纽约证券交易所(NYSE)推出了零售流动性计划(RLP)。RLP使做市商能够报价黑暗(未显示)限价单,这些限价单只能由来自零售交易商的市场订单来完成。Garriott和Walton利用纽约证券交易所的交易和报价(TAQ)数据研究了细分对信息和市场质量的影响。他们利用Hasbrouck (the Journal of Finance, 1991)的技术,通过计算订单流中每个组成部分的信息份额,分析了细分影响市场质量的机制。接下来,科尔、范内斯和范内斯研究了自然灾害(龙卷风、野火和飓风/热带风暴)发生之前、发生期间和发生之后的市政债券市场活动。利用2010 - 2013年的市政债券交易样本,他们发现自然灾害会影响市政债券交易。它们还确定受自然灾害影响的债券与相关债券之间存在联系。为了继续,Kakushadze和Yu提供了一个明确的公式算法和源代码,用于构建只做多的基准投资组合,然后在只做多的市场跑赢策略中使用这些基准。他们使用一个多因素风险模型(利用多层次的行业分类或聚类),专门为只做多的基准投资组合量身定制,以计算它们的权重,这些权重在它们的结构中是明确的正的。为了总结这一问题,Graf Plessen和Bemporad提出了一种简单的方法,用于交易成本和多样化约束下的后先验(历史)多变量多阶段最优交易。所开发的方法基于高效的图生成和后续图搜索,并在实际数据上进行了定量评估。这项工作的基本动机是为监督机器学习准备金融时间序列数据的标记。一如既往,我们欢迎您的投稿。我们非常重视您的意见和建议,所以请给我们发邮件至journals@investmentresearch.org。

Retail Order Flow Segmentation 零售订单流细分
Pub Date : 2018-06-21 DOI: 10.3905/jot.2018.13.3.013
Corey Garriott, Adrian Walton
In August 2012, the New York Stock Exchange launched the Retail Liquidity Program (RLP), a new trading facility that enables participating organizations to quote dark limit orders available only to retail traders. The facility increased the information content of the order flow by distinguishing retail trades from relatively more informed trades. Stocks with substantial RLP activity experienced no material changes in relative bid–ask spreads, effective spreads, and price impacts, and had mildly decreased return autocorrelations.
2012年8月,纽约证券交易所推出了零售流动性计划(RLP),这是一种新的交易设施,使参与机构能够报价仅限零售交易者使用的暗限价订单。该设施通过区分零售交易与相对更知情的交易,增加了订单流的信息含量。具有大量RLP活动的股票在相对买卖价差、有效价差和价格影响方面没有实质性变化,并且收益自相关性略有下降。

Municipal Bond Trading, Information Relatedness, and Natural Disasters 市政债券交易、信息关联与自然灾害
Pub Date : 2018-06-01 DOI: 10.3905/jot.2018.1.063
Brittany Cole, Bonnie F. Van Ness, R. V. Ness
The authors study municipal bond market activity before, during, and after natural disasters (tornadoes, wildfires, and hurricanes/tropical storms). Using a sample of municipal bond trades from 2010 to 2013, they find that natural disasters influence municipal bond trading. Specifically, they show that spreads are lower on both tornado and wildfire event days and during the following five trading days than during the preceding five trading days. Although the study does not document a relationship between hurricane events and spreads, the authors show that spreads fall during the five days following the hurricane compared with the five trading days before the event. Generally, the study shows an increase in dollar volume in the five trading days following all three types of natural disasters. The authors also find linkages between the bonds affected by natural disasters and related bonds.
作者研究了自然灾害(龙卷风、野火和飓风/热带风暴)发生之前、期间和之后的市政债券市场活动。他们以2010年至2013年的市政债券交易为样本,发现自然灾害会影响市政债券交易。具体来说,它们表明,在龙卷风和野火事件日以及随后的五个交易日内,价差都低于前五个交易日。虽然这项研究没有记录飓风事件和利差之间的关系,但作者表明,与飓风发生前的5个交易日相比,飓风过后的5天利差下降。总的来说,研究表明,在这三种自然灾害发生后的五个交易日里,美元交易量都有所增加。作者还发现,受自然灾害影响的债券与相关债券之间存在联系。

Betas, Benchmarks, and Beating the Market beta版、基准和击败市场
Pub Date : 2018-05-30 DOI: 10.2139/ssrn.3187779
Zurab Kakushadze, Willie Yu
This article provides an explicit formulaic algorithm and source code for building long-only benchmark portfolios and then using these benchmarks in long-only market outperformance strategies. The benchmarks (or the corresponding betas) do not involve any principal components, nor do they require iterations. Instead, the authors use a multifactor risk model (which uses multilevel industry classification or clustering) specifically tailored to long-only benchmark portfolios to compute their weights, which are explicitly positive in the construction.
本文提供了一个明确的公式化算法和源代码,用于构建只做多的基准投资组合,然后在只做多的市场胜出策略中使用这些基准。基准测试(或相应的beta测试)不涉及任何主要组件,也不需要迭代。相反,作者使用了一个多因素风险模型(使用多层次行业分类或聚类),专门针对只做多的基准投资组合来计算它们的权重,这在结构中是明确的正的。

Trading the VIX Futures Roll Using Exchange-Traded Funds 使用交易所交易基金交易波动率指数期货卷
Pub Date : 2018-03-10 DOI: 10.3905/jot.2018.13.2.047
D. Buehler, Patrick Cusatis
This article examines the use of exchange-traded funds (ETFs) in the implied volatility market. Because the Volatility Index (VIX) cannot be directly traded and the VIX futures market is accessible only to institutional investors, the authors develop and analyze how individual investors can employ a VIX-based strategy using ETFs. They test a trading strategy using the ProShares VIXY and SVXY ETFs and compare the performance to a similar strategy using VIX futures and the S&P 500. They select these two ETFs because they can directly compare a long or short trading strategy using VIX futures. While the ETF trading strategies produce excess returns, these returns come with significant downside volatility.
本文考察了交易所交易基金(etf)在隐含波动率市场中的应用。由于波动率指数(VIX)不能直接交易,而VIX期货市场仅对机构投资者开放,因此作者开发并分析了个人投资者如何使用etf采用基于波动率指数的策略。他们使用ProShares VIXY和SVXY etf测试了一种交易策略,并将其与使用VIX期货和标准普尔500指数的类似策略进行了比较。他们选择这两种etf是因为他们可以直接比较使用波动率指数期货的多头或空头交易策略。虽然ETF交易策略产生了超额回报,但这些回报伴随着显著的下行波动性。

A Posteriori Multistage Optimal Trading under Transaction Costs and a Diversification Constraint 交易成本和多元化约束下的后验多阶段最优交易
Pub Date : 2017-09-21 DOI: 10.3905/jot.2018.1.064
Mogens Graf Plessen, A. Bemporad
This article presents a simple method for a posteriori (historical) multivariate, multistage optimal trading under transaction costs and a diversification constraint. Starting from a given amount of money in some currency, the authors analyze the stage-wise optimal allocation over a time horizon with potential investments in multiple currencies and various assets. Three variants are discussed: unconstrained trading frequency, a fixed number of total admissible trades, and waiting a specific time period after every executed trade until the next trade. The developed methods are based on efficient graph generation and consequent graph search and are evaluated quantitatively on real-world data. The fundamental motivation of this work is preparatory labeling of financial time-series data for supervised machine learning.
本文提出了一种在交易成本和多样化约束下的后验(历史)多元多阶段最优交易的简单方法。从某种货币的给定金额开始,作者分析了在一段时间内对多种货币和各种资产进行潜在投资的阶段性最佳配置。讨论了三种变体:不受约束的交易频率,固定的总允许交易数量,以及在每次执行交易后等待特定的时间段直到下一笔交易。所开发的方法基于高效的图生成和后续图搜索,并在实际数据上进行了定量评估。这项工作的基本动机是为监督机器学习准备金融时间序列数据的标记。

Can Trading Volume Validate Extreme Price Movements in the Age of Higher Algorithmic Trading Activities? 交易量能验证高算法交易活动时代的极端价格走势吗?
Pub Date : 2017-03-31 DOI: 10.3905/jot.2017.12.2.073
Yu-Jung L. Avis, Chingfu Chang, Dandan Wu
We take the perspective of the practitioner who focuses on following the longitudinal performance of specific stocks and investigate whether volume may provide guidance on days of extreme price movements. For days of extreme price increases (the winners) and extreme price decreases (the losers), we show that extreme low volume is associated with future return reversal, whereas extreme high volume does not necessarily lead to future return persistence. We look at daily data from 1989 to 2014, and we consider 2004 to be the year when algorithmic trading activities began to intensify. We find that the usefulness of extreme low volume in repudiating extreme price movements has been diminishing since 2004. To the extent that extreme low volume may still be applied to repudiate extreme price movements, a practitioner may limit his or her scope to the low-volume winners and losers of small capitalization. In addition, we use Chinese data from 1992 to 2014 to replicate the tests. We find that the same characteristics are not shown there, indicating a lack of universality of the conclusions we derived from the U.S. data.
我们采取实践者的观点,专注于跟踪特定股票的纵向表现,并调查交易量是否可以在极端价格波动的日子里提供指导。对于价格极端上涨(赢家)和价格极端下跌(输家)的日子,我们表明,极低的成交量与未来的回报反转有关,而极高的成交量并不一定导致未来的回报持续。我们查看了1989年至2014年的每日数据,我们认为2004年是算法交易活动开始加剧的一年。我们发现,自2004年以来,极低交易量在否定极端价格变动方面的作用一直在减弱。在某种程度上,极低的交易量可能仍然适用于拒绝极端的价格变动,从业者可能会限制他或她的范围,以低交易量的赢家和小资本的输家。此外,我们使用1992年至2014年的中国数据来重复测试。我们发现,同样的特征在那里没有显示出来,这表明我们从美国数据中得出的结论缺乏普遍性。

Quintet Volume Projection 五重奏体投影
Pub Date : 2017-03-31 DOI: 10.3905/jot.2017.12.2.028
V. Markov, Olga Vilenskaia, Vlad Rashkovich
We present a set of models that are relevant for predicting various aspects of intraday trading volume for equities and showcase them as an ensemble that projects volume in unison. We introduce econometric methods for predicting end-of-day volume, volume u-curve, close auction volume, and special day seasonalities and emphasize a need for a unified approach in which all submodels work consistently with each other. We rely on the application of Bayesian methods, which have the advantage of providing adaptive and parameterless estimations of volume for a broad range of equities while automatically taking into account uncertainty in the model input components. We discuss the shortcomings of traditional statistical error metrics for calibrating volume prediction and introduce asymmetrical logarithmic error to overweight an overestimation risk.
我们提出了一组模型,这些模型与预测股票盘中交易量的各个方面有关,并将它们作为一个整体展示,以一致的方式预测交易量。我们介绍了计量经济学方法来预测日终成交量、成交量u型曲线、成交成交量和特殊的日季节性,并强调需要一种统一的方法,在这种方法中,所有子模型相互一致地工作。我们依赖于贝叶斯方法的应用,它的优点是为大范围的股票提供自适应和无参数的交易量估计,同时自动考虑模型输入成分的不确定性。讨论了传统统计误差指标用于校准体积预测的缺点,并引入非对称对数误差来衡量超重和高估风险。

We discuss the shortcomings of traditional statistical error metrics for calibrating volume prediction and introduce asymmetrical logarithmic error to overweight an overestimation risk.","PeriodicalId":254660,"journal":{"name":"The Journal of Trading","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115304408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using high-frequency datasets, we examine price discovery and its determinants for equivalent instruments across futures markets, electronically traded exchange-traded funds (ETFs), and spot markets. We compare futures to ETFs—leveraged and unleveraged—for stock indexes, using both a normal period and the 2008 financial crisis. Yan and Zivot’s information leadership procedure is employed to determine which instrument dominates price discovery. We then examine the determinants and characteristics of the price discovery process using Hasbrouck’s sequential trading model for the price impact of large trades. We find that most price discovery occurs in the more liquid and highly leveraged futures market. Although liquidity declined in all markets during the financial crisis, the relative contribution of ETFs to price discovery increased. We also find that the information leadership shares of futures and ETFs depend on the ratio of the quoted percentage spread between futures and ETFs and the aggregate volatility occurring in these markets.
使用高频数据集,我们研究了期货市场、电子交易交易所交易基金(etf)和现货市场等价工具的价格发现及其决定因素。我们以正常时期和2008年金融危机为例,比较了股指期货和etf(杠杆和非杠杆)。采用Yan和Zivot的信息领导程序来确定哪种工具在价格发现中占主导地位。然后,我们使用Hasbrouck的大型交易价格影响的顺序交易模型来检查价格发现过程的决定因素和特征。我们发现,大多数价格发现发生在流动性更强、杠杆率更高的期货市场。尽管在金融危机期间,所有市场的流动性都有所下降,但etf对价格发现的相对贡献却有所增加。我们还发现,期货和etf的信息领先份额取决于期货和etf之间的报价百分比差与这些市场发生的总波动率的比率。
