    1Automatic one two three

    介绍:在本文中,我们展示了如何使用停止和反向过程从市场价格中自动计算市场技术趋势。基本工具是一个所谓的minmax过程,表明所有相关的最小值和最大值。 对于minmax过程的存在,我们给出了构造性的证明。 根据这个1-2-3趋势指标,可以自动实现几个成功的趋势跟踪交易策略。

    2Gaussian process-based algorithmic trading strategy identification

    关键字:逆向强化学习、高斯过程、高频交易、算法贸易、行为金融、马尔科夫决定过程、支持向量机

    介绍:In this paper, we consider the basic problems of categorizing and recognizing traders (or, equivalently, trading algorithms) on the basis of observed limit orders.These problems are of interest to regulators engaged in strategy identification for the purposes of fraud detection and policy development. Methods have been suggested in the literature for describing trader behaviour using classification rules defined over a feature space consisting of summary trading statistics of volume and inventory, along with derived variables that reflect the consistency of buying or selling behaviour. Our principal contribution is to suggest an entirely different feature space that is constructed by inferring key parameters of a sequential optimization model that we take as a surrogate for the decision-making process of the traders. In particular, we model trader
    behaviour in terms of a Markov decision process. We infer the reward (or objective) function for this process from observations of trading actions using a process from machine learning known as inverse reinforcement learning (IRL). The reward functions learned through IRL then constitute a feature space that can be the basis for supervised learning (for classification or recognition of traders) or unsupervised learning (for categorization of traders). Making use of a real-world data-set from the E-Mini futures contract, we compare two principal IRL variants, linear IRL and Gaussian Process IRL, against a method based on summary trading statistics. Results suggest that IRL-based feature 
    spaces support accurate classification and meaningful clustering. Further, we argue that, because they attempt to learn traders’ underlying value propositions under different market conditions, the IRL methods are more informative and robust than the summary statistic-based approach and are well suited for discovering new behaviour patterns of market participants.


    3Empirical properties of asset returns: stylized facts and statistical issues

    介绍:我们提供一组从统计数据出发的风格化的实证事实分析各类金融市场的价格变动。 我们第一讨论财务时间所有统计研究共同的一些一般问题系列。 然后描述资产回报的各种统计属性:分布特性,尾部特性和极端波动时间和跨越的规律性,线性和非线性回报股票。 我们的描述强调各种各样的属性市场和工具。 然后我们将显示这些统计属性使许多用于研究财务的常见统计方法无效数据集,并检查每一个遇到的一些统计问题案件。

    High-frequency trading in a limit order book

    介绍:We study a stock dealer’s strategy for submitting bid and ask quotes in a limit order book. The agent faces an inventory risk due to the diffusive nature of the stock’s mid-price and a transactions risk due to a Poisson arrival of market buy and sell orders. After setting up the agent’s problem in a maximal expected utility framework, we derive the solution in a two step procedure. First, the dealer computes a personal indifference valuation for the stock, given his current inventory. Second, he calibrates his bid and ask quotes to the market’s limit order book. We compare this ”inventory-based” strategy to a ”naive” best bid/best ask strategy by simulating stock price paths and displaying the P&L profiles of both strategies. We find that our strategy has a P&L profile that has both a higher return and lower variance than the benchmark strategy.

    Portfolio Selection with Higher Moments


    介绍:We build on the Markowitz portfolio selection process by incorporating higher order moments of the assets, as well as utility functions based on predictive asset returns. We propose the use of the skew normal distribution as a characterization of the asset returns. We show that this distribution has many attractive features when it comesto modeling multivariate returns. Preference over portfolios is framed in terms of expected utility maximization. We discuss estimation and optimal portfolio selection using Bayesian methods. These methods allow for a comparison to other optimization approaches where parameter uncertainty is either ignored or accommodated in a non traditional manner. Our results suggest that it is important to incorporate higher order moments in portfolio selection. Further, we show that our approach leads to higher expected utility than the resampling methods common in the practice of finance.



    10 WHAT GOOD IS A VOLATILITY MODEL?

    介绍:A volatility model must be able to forecast volatility; this is the central requirement in almost all financial applications. In this paper we outline some stylised facts about volatility that should be incorporated in a model; pronounced persistence and meanreversion, asymmetry such that the sign of an innovation also affects volatility and the possibility of exogenous or pre-determined variables influencing volatility. We use data on the Dow Jones Industrial index to illustrate these stylised facts, and the ability of GARCH-type models to capture these features. We conclude with some challenges for future research in this area.
