精彩书摘

The financial markets contain many sources of risk. When dealing with severalsources of risk at a time we cannot treat them separately: the joint structureof multi-dimensionai randomness contains a wealth of information that goesbeyond the juxtaposition of the information contained in each single variable.
In this chapter we discuss multivariate statistics. The structure of thischapter reflects that of Chapter 1: to ease the comprehension of the multi-variate case refer to the respective section in that chapter. For more on thissubject see also references such as Mardia, Kent, and Bibby （1979）, Press（1982） and Morrison （2002）.
In Section 2.1 we introduce the building blocks of multivariate distributionswhich are direct generalizations of the one-dimensional case. These include thethree equivalent representations of a distribution in terms of the probabilitydensity function, the characteristic function and the cumulative distributionfunction.
In Section 2.2 we discuss the factorization of a distribution into its purelyunivariate components, namely the marginal distributions, and its purely jointcomponent, namely the copula. To present copulas we use the leading exampleof vanilla options.
In Section 2.3 we introduce the concept of independence among randomvariables and the related concept of conditional distribution.
In Section 2.4 we discuss the location summary statistics of a distributionsuch as its expected value and its mode, and the dispersion summary statisticssuch as the covariance matrix and the modal dispersion. We detail the geo- metrical representations of these statistics in terms of the location-dispersionellipsoid, .and their probabilistic interpretations in terms of a multivariateversion of Chebyshevs inequality. We conclude introducing more summarystatistics such as the multivariate moments, which provide a deeper insightinto the shape of a multivariate distribution.

前言/序言

　　In an asset allocation problem the investor， who can be the trader， or thefund manager， or the private investor， seeks the combination of securitiesthat best suit their needs in an uncertain environment. In order to determinethe optimum allocation， the investor needs to model， estimate， assess andmanage uncertainty.
　　The most popular approach to asset allocation is the mean-variance frame-work pioneered by Markowitz， where the investor aims at maximizing theportfolios expected return for a given level of variance and a given set of investment constraints. Under a few assumptions it is possible to estimate themarket parameters that feed the model and then solve the ensuing optimization problem.
　　More recently， measures of risk such as the value at risk or the expectedshortfall have found supporters in the financial community. These measuresemphasize the potential downside of an allocation more than its potential benefits. Therefore， they are better suited to handle asset allocation in modern，highly asymmetrical markets.
　　All of the above approaches are highly intuitive. Paradoxically， this can bea drawback， in that one is tempted to rush to conclusions or implementations，without pondering the underlying assumptions.
　　For instance， the term "mean-variance" hints at the identificati 风险和资产配置（英文版） [Risk and Asset Allocation] 下载 mobi epub pdf txt 电子书 格式

投资组合保险策略是在将一部分资金投资于无风险资产从而保证资产组合的最低价值的前提下，将其余资金投资于风险资产并随着市场的变动调整风险资产和无风险资产的比例，同时不放弃资产升值潜力的一种动态调整策略。当投资组合价值因风险资产收益率的提高而上升时，风险资产的投资比例也随之提高；反之则下降。

资产配置在不同层面有不同含义，从范围上看，可分为全球资产配置、股票债券资产配置和行业风格资产配置；从时间跨度和风格类别上看，可分为战略性资产配置、战术性资产配置和资产混合配置；从资产管理人的特征与投资者的性质上，可分为买人并持有策略(Buy-and-hold Strategy)、恒定混合策略(Constant-mix Strategy)、投资组合保险策略(Portfolio-insurance Strategy)和战术性资产配置策略(Tactical Asset Allocation Strategy)。

(4)资产配置一般遵循“回归均衡”的原则，这是动态资产配置中的主要利润机制。
