Value-at-risk with heavy-tailed risk factors 具有重尾风险因素的风险价值
P. Glasserman, P. Heidelberger, P. Shahabuddin
This paper develops methods for computationally efficient calculation of value-at-risk (VAR) in the presence of heavy-tailed risk factors. The methods model market risk factors through a multivariate t-distribution, which has both heavy tails and empirical support. Our key mathematical result is a transform analysis of a quadratic form in multivariate t random variables. Using this result, we develop two computational methods. The first uses Fourier transform inversion to develop a heavy-tailed delta-gamma approximation; this method is extremely fast, but like any delta-gamma method is only as accurate as the quadratic approximation. For greater accuracy, we therefore develop an efficient Monte Carlo method; this method uses our heavy-tailed delta-gamma approximation as a basis for variance reduction. Specifically, we use the numerical approximation to design a combination of importance sampling and stratified sampling of market scenarios that can produce enormous speed-ups compared with standard Monte Carlo.
本文提出了在存在重尾风险因素的情况下,有效计算风险价值(VAR)的方法。该方法通过多元t分布模型对市场风险因素进行建模,该模型既有重尾,又有经验支持。我们的关键数学结果是多元t随机变量中二次型的变换分析。利用这一结果,我们发展了两种计算方法。第一种方法使用傅里叶变换反演来建立一个重尾delta-gamma近似;这个方法非常快,但是像任何的-方法一样,它只能和二次逼近一样精确。为了提高准确性,我们开发了一种有效的蒙特卡罗方法;该方法使用我们的重尾delta-gamma近似作为减少方差的基础。具体来说,我们使用数值近似来设计市场场景的重要抽样和分层抽样的组合,与标准蒙特卡罗相比,可以产生巨大的加速。

FeNAs: a fuzzy e-negotiation agents system 模糊电子谈判代理系统
R. Kowalczyk, Van Bui
This paper overviews an experimental fuzzy e-negotiation agents system, FeNAs, that can support automated negotiation in the presence of imprecise information. The system uses the principles of fuzzy constraint-based reasoning involving fuzzy constraint modeling, satisfaction and propagation. It is demonstrated with a prototype for the used car-trading problem. The system supports multi-issue negotiations where offers consist of a number of issues that can include the price of the car and other value-added services such as warranty and the value of the trade-in car. The agents exchange offers on the basis of the information available and negotiation strategies used by each party. Information available to both the buyer and the seller can include the make, model, color, transmission, age and mileage of the car. Each agent has also some private information including preferences, priorities and financial constraints that are not available to other agents. This information can be imprecise where constraints, preferences and priorities are defined as fuzzy constraints describing the level of satisfaction of an agent (and its user) with different potential solutions. The overall objective of an agent is to find a solution that maximizes the agent's utility at the highest possible level of constraint satisfaction subject to its acceptability by other agents. During negotiation the agents follow a common protocol of negotiation and individual negotiation strategies.
本文概述了一种实验性模糊电子协商代理系统FeNAs,该系统能够在不精确信息存在的情况下支持自动协商。该系统采用基于模糊约束的推理原理,包括模糊约束建模、满足和传播。并以二手车交易问题为例进行了验证。该系统支持多议题谈判,其中报价包括许多议题,包括汽车价格和其他增值服务,如保修和以旧换新汽车的价值。代理们在双方可用信息和谈判策略的基础上交换报价。买方和卖方都可以获得的信息包括汽车的品牌、型号、颜色、变速器、车龄和里程。每个代理也有一些私人信息,包括其他代理无法获得的偏好、优先级和财务约束。当约束、偏好和优先级被定义为描述代理(及其用户)对不同潜在解决方案的满意度的模糊约束时,这些信息可能是不精确的。agent的总体目标是找到一个解决方案,在约束满足的最高可能水平下,在其他agent可接受的情况下,使agent的效用最大化。在谈判过程中,agent遵循共同的谈判协议和各自的谈判策略。

Time series for currency exchange rate of the Brazilian Real 巴西雷亚尔货币汇率的时间序列
Marcelo A. Bittencourt, F. Lin
In our global village the currency exchange rate of a country is considered by international investors as an important yardstick for measuring the health of its economy. In the paper an analysis is made of the Brazilian Real using three different methodologies: the Box-Jenkins or SARIMA; exponential smoothing; and a backpropagation neural network trained by the Levenberg-Marquardt algorithm. Not surprisingly, our study indicates that given the same input data different paradigms yield different results. However, presumably due to the intervention of the Central Bank, the time series exhibits quasiperiodic behaviour. Extrapolations are made into the future. Possible implications are discussed. Our methodology can be applied to any currency extant.
在我们这个地球村,一个国家的货币汇率被国际投资者视为衡量其经济健康状况的重要尺度。本文使用三种不同的方法对巴西雷亚尔进行了分析:Box-Jenkins或SARIMA;指数平滑法;以及由Levenberg-Marquardt算法训练的反向传播神经网络。毫不奇怪,我们的研究表明,给定相同的输入数据,不同的范式产生不同的结果。然而,可能是由于中央银行的干预,时间序列表现出准周期行为。外推是针对未来的。讨论了可能的影响。我们的方法适用于任何现存的货币。

Sixteenths or pennies? Observations from a simulation of the Nasdaq stock market 16美分还是1美分?从纳斯达克股票市场的模拟观察
V. Darley, Alexander Outkin, T. Plate, Frank Gao
We have built a model that represents a highly realistic picture of a dealer-mediated market like Nasdaq, with the flexibility to model many features of real-world markets. While we have conducted a fairly significant amount of research using the model, we have limited it to four areas: 1) investigating, mainly in a qualitative fashion, the consequences of regulatory and structural changes to the market (the most important being tick size effects); 2) investigating whether our model, at least in a stylized fashion, is able to replicate some of the observed features of real-world markets; 3) validating the model (this encompasses the previous two points); 4) designing learning agents, and investigating the behaviors they learn and their ability to perform profitably in the market. Our results are significant in two respects. First, the model is robust: the simulated market as a whole, as well as the investors and dealers that make it up, perform realistically under a wide variety of conditions. Second, the market dynamics produced by the model have the same qualitative properties as those observed in real markets. Thus the model provides a test bed in which to investigate the effects of changes in market rules and conditions, and to investigate other aspects of the Nasdaq market.
我们已经建立了一个模型,它代表了像纳斯达克这样的交易商中介市场的高度现实的图景,具有灵活性,可以模拟现实市场的许多特征。虽然我们使用该模型进行了相当多的研究,但我们将其限制在四个领域:1)调查,主要是以定性的方式,监管和结构变化对市场的影响(最重要的是蜱虫规模效应);2)调查我们的模型是否,至少以一种程式化的方式,能够复制一些观察到的现实世界市场的特征;3)验证模型(包括前两点);4)设计学习型智能体,研究它们学习的行为及其在市场上盈利的能力。我们的结果在两个方面意义重大。首先,这个模型是稳健的:模拟的市场作为一个整体,以及组成这个市场的投资者和交易商,在各种各样的条件下都表现得很真实。其次,由模型产生的市场动态具有与在实际市场中观察到的相同的定性性质。因此,该模型为研究市场规则和条件变化的影响以及研究纳斯达克市场的其他方面提供了一个测试平台。

An analytic framework for pricing energy derivatives 能源衍生品定价的分析框架
Ilia Bouchouev
Despite its obvious shortcoming, Black's formula for futures options is still widely used for pricing energy derivatives. The lognormality assumption that underlies this formula is inconsistent with the market implied distribution for many commodities and as a result, out-of-the-money options are mispriced by Black's formula. Our objective is to develop a self-consistent term-structure pricing framework based on the general diffusions and derive simple pricing formulas similar to Black's one with a few additional parameters that can be easily estimated from market prices of liquid options. We assume the following risk neutral dynamics for futures prices: df(t,T)=/spl sigma//sub 1/(f,t,T)dz/sub 1/+/spl sigma//sub 2/(f,t,T)dz/sub 2/, dz/sub 1/dz/sub 2/=0. The value of the discounted European call option V(t,f) on T-maturity futures struck at K is determined as the solution to the following diffusion problem /spl part/V//spl part/t+ 1/2 (/spl sigma//sub 1//sup 2/(f,t,T)+/spl sigma//sub 2//sup 2/(f,t,T))/spl part//sup 2/V//spl part/f/sup 2/, V(T,f)=(f-K)/sup +/.
尽管存在明显的缺陷,布莱克的期货期权公式仍被广泛用于能源衍生品的定价。作为该公式基础的对数正态性假设与许多商品的市场隐含分布不一致,因此,场外期权被布莱克的公式错误定价。我们的目标是建立一个基于一般扩散的自一致期限结构定价框架,并推导出类似于布莱克的定价公式的简单定价公式,这些公式带有一些可以从流动性期权的市场价格中轻松估计的附加参数。我们假设期货价格的风险中性动态:df(t, t)=/spl sigma//下标1/(f,t, t)dz/下标1/+/spl sigma//下标2/(f,t, t)dz/下标2/,dz/下标1/dz/下标2/=0。在K点成交的t -到期期货的贴现欧式看涨期权V(t,f)的价值被确定为以下扩散问题的解/spl part/V//spl part/t+ 1/2 (/spl sigma//sub 1//sup 2/(f,t, t)+/spl sigma//sub 2//sup 2/(f,t, t))/spl part//sup 2/V//spl part/f/sup 2/, V(t,f) =(f-K)/sup +/。

Automatic on-line signature verification based on multiple models 支持多模型在线签名自动验证
Mingming Ma, W. S. Wijesoma
The paper proposes an automatic on-line signature verification system based on multiple models, a frequency function model, a shape-related parameter model, and a dynamics-related parameter model. This system uses fuzzy logic instead of the traditional Euclidean distance metric for comparison, and uses a personalized feature selection algorithm based on the DP function for parameter model building. From the statistical results it is concluded that fuzzy logic, the personalized feature selection algorithm based on the DP function and the multiple models method are helpful for automatic on-line signature verification.

Financial time series forecasts using fuzzy and long memory pattern recognition systems 金融时间序列预测使用模糊和长记忆模式识别系统
Sameer Singh, J. Fieldsend
In this paper, the concept of long memory systems for forecasting is developed. The pattern modelling and recognition system and fuzzy single nearest neighbour methods are introduced as local approximation tools for forecasting. Such systems are used for matching the current state of the time-series with past states to make a forecast. In the past, the PMRS system has been successfully used for forecasting the Santa Fe competition data. In this paper, we forecast the FTSE 100 and 250 financial returns indices, as well as the stock returns of five FTSE 100 companies and compare the results of the two different systems with those of exponential smoothing and random walk on seven different error measures. The results show that pattern recognition based approaches in time-series forecasting are highly accurate. Simple theoretical trading strategies are also mentioned, highlighting real applications of the system.

Classes of preferences of portfolio investors for multi-period case and their asymptotic properties 多周期情况下证券投资者的偏好类别及其渐近性质
G. A. Agasandian
Methods for the definition of preferences of portfolio investors for the multi-period investment horizon are considered and the dependence of investor behavior on the horizon length is studied. It is assumed that the capitalization share of each portfolio security doesn't vary in time. Hence, portfolio restructuring on each step of the investment process is necessary to allocate the whole portfolio value between the component securities in a proportion chosen by the investor. It is supposed that the restructuring transaction costs are equal to zero. In portfolio theory, different approaches are used. In this paper, three of them are considered. The first involves the definition of the effective portfolio set, the second involves the concept of indifference curves and the third involves drawdown criteria.
考虑了证券投资者对多期投资期限偏好的定义方法,并研究了投资者行为对期限长度的依赖关系。假设每个投资组合证券的资本化份额不随时间变化。因此,在投资过程的每一步都需要对投资组合进行重组,以便按照投资者选择的比例在组成证券之间分配整个投资组合的价值。假设重组交易成本为零。在投资组合理论中,使用了不同的方法。本文考虑了其中的三种。第一个涉及有效投资组合集的定义,第二个涉及无差异曲线的概念,第三个涉及回撤标准。

New Sharpe-ratio-related methods for portfolio selection 新的夏普比率相关的投资组合选择方法
Kei-Keung Hung, C. Cheung, L. Xu
In this paper, we formulate methods for portfolio selection for investors with different attitudes in the return-risk trade-off. We defined an objective function based on the Sharpe ratio (Sharpe, 1966) and downside risk (Fishburn, 1977), plus introducing two new terms called "upside volatility" and "diversification". We propose the maximization of the objective function WRT the portfolio weights as a method of determining suitable weights. We also propose practical methods for controlling the expected return while minimizing risk, of controlling risk while maximising expected return. Experiments showed that the proposed methods yielded successful results.
在本文中,我们制定了不同态度的投资者在收益-风险权衡中的投资组合选择方法。我们根据夏普比率(Sharpe, 1966)和下行风险(Fishburn, 1977)定义了一个目标函数,并引入了两个新术语,即“上行波动性”和“多样化”。我们提出了投资组合权重目标函数WRT的最大化作为确定合适权重的方法。我们还提出了在控制预期收益的同时最小化风险,在控制风险的同时最大化预期收益的实用方法。实验表明,该方法取得了较好的效果。

Experiments showed that the proposed methods yielded successful results.","PeriodicalId":308591,"journal":{"name":"Proceedings of the IEEE/IAFE/INFORMS 2000 Conference on Computational Intelligence for Financial Engineering (CIFEr) (Cat.

Apples to oranges: reconciling "vegas" from inconsistent valuation models by a stochastic change of coordinates 苹果到橘子:通过坐标的随机变化调和不一致估值模型中的“维加斯”
A. Kuruc
We present fundamental research on new notions of "vega" that, unlike the usual ones, can sensibly be added together across different valuation models. First, we describe the basic ideas using simple models of equity prices. Next, we outline the application of these ideas to interest-rate derivatives.
我们对“织女星”的新概念进行了基础研究,与通常的概念不同,这些概念可以在不同的估值模型中合理地加在一起。首先,我们用简单的股票价格模型来描述基本思想。接下来,我们将概述这些思想在利率衍生品中的应用。
