CFA一级金融数量分析的三个难点剖析

全球最大的CFA(特许金融分析师)培训中心总部地址:上海市虹口区花园路171号A3幢高顿教育电话:400-600-8011网址: 微信公众号:gaoduncfa 1 CFA 一级金融数量分析的三个难点剖析 根据中心极限定理(Central Limit Theorem),如果乒乓球的随机数容量很大,即不符合正态分布, 其样本均值将服从m 为总体均值,s 为总体标准差除以n 平方根的正态分布。
在估量数据的标准误差时,考生常常疑惑何时应当用标准差s(standard deviation)度量、何时又应该用s/√n (standard deviation divided by square root of n)度量。
考生须牢记,在计算样本均值的置信区间时,就要用s/√n 来度量误差。
举例来说,考虑100个标上了正态随机数的乒乓球, 这串随机数的均值(mean)是0,标准差(standard deviation)是10。
根据置信区间的计算,将有95%的随机数落在(-1.95*10,1.95*10)区间内。
现在考虑9个样本球,并假定这9个乒乓球的随机数均值为0,样本均值标准差为10/√9 = 10/3 = 3.33. 那么这9个样本球的均值有95%的概率落在(-1.96*3.33,1.96*3.33)区间内。
样本的规模越大,样本均值就越接近真实均值。
现在若考虑100个样本球随机数,均值标准差为10/√100 =10/10 = 1,则这100个随机数的均值95%的概率落在(-1.96,1.96)。
计算货币的时间价值,考生遇到的难点往往是计算在n 期时间后开始的(永续)年金的折现值。
需要注意的是,考生若将计算器设置在END 模式,计算出的现值即折现到第一个支付日的前一日。
各位考生,2015年CFA 备考已经开始,为了方便各位考生能更加系统地掌握考试大纲的重点知识,帮助大家充分备考,体验实战,网校开通了全免费的高顿题库(包括精题真题和全真模考系统),题库里附有详细的答案解析,学员可以通过多种题型加强练习,通过针对性地训练与模考,对学习过程进行全面总结。

CFA一级考试数量分析三大指标
在CFA考试中,数量分析有哪三大指标?
在CFA学习过程中考生会发现:
量化中学的偏度(Skewness)这个概念很少被人使用,实际上这个概念在解读历史收益率分布时非常有用。
因为它决定了我们投资组合的尾部风险(TailRisk),更决定了我们下一步hedge的策略。
在看相关的数据之前,建议考生先认识一下这个研究中投资组合的构建:SMB,HML,UMD这三种不同类型的投资组合。
SMB:将样本股票按照市值降序排列——分成大盘股(Big,简写为B)和小盘股(Small,简写为S)
两组——给每组股票求出平均月度收益率——用小盘股的平均收益率减去大盘股的平均收益率,得到一组风格投资(Size)观测值SMB。
HML:将大小盘样本股票继续细分为高估值(H,降序排列前30%)、中估值(M,降序排列中40%)、低估值(L,降序排列最后30%)
三组子样本——估值采用BM法,即账面价值/市值——计算高和低两个子样本的平均月度收益率,用前者减去后者得到一组价值投资(Value)观测值HML。
UMD:将样本股票算出过去6个月的滚动收益率(Accumulatedreturn)降序排列。
将排名最低的30%定义为下降趋势股票(Down,简写为D),将排名最高的30%定义为上升趋势股票(Up,简写为U)。
将两组样本股票收益率按照等权重加权之后得到加权平均收益率,两个加权平均收益率相减,得到一组“趋势投资”(Momentum)观测值UMD。

CFA一级考试《数量分析》考试大纲
![CFA一级考试《数量分析》考试大纲](https://img.taocdn.com/s3/m/48fe707b76232f60ddccda38376baf1ffc4fe393.png)
CFA一级考试《数量分析》考试大纲CFA一级考试大纲科目《数量分析》中的考纲变化:数量科目权重未变8-12%,但被移动到第一个部分,替代道德的位置。
CFA一级考试总体来说,本科目是新考纲中变动较大的科目,主要体现在协会更加注意学问的有用性,与当前金融行业的进展特别契合。
新增两个章节分别为:Organizing,Visualizing,And Describing Data以及Introduction To Linear Regression,同时删除Statistical Concepts and Market Returns,其余每一个reading 都有少量的增减。
变化分析:第一个新增的"Organizing,Visualizing,and Describing Data'其实是原本"Statistical Concepts and Market Returns'的进阶版本。
在新增的这个章节中,除了保留对数据描述性的分析介绍之外,更加注意对数据进行系统性的分类、整理和可视化分析,介绍了在实务中常用的一些数据分析手段和方法论,比如热力图、树状图、云图、气泡线图等。
另一个新增的章节"Introduction to Linear Regression'原本是二级数量中的一个章节,这个章节主要讲的是线性回归的基本规律和原理,是为二级数量中多元回归打基础的一个章节。
另外,线性回归是金融数据分析中常用的一个量化分析模型,更加偏重应用,突出了协会对量化建模的重视。
详细变动内容:STUDY SESSION 1-QUANTITATIVE METHODS(1)Reading 1.THE TIME VALUE OF MONEY(原Reading 6-R6):(1)由solve time value of money problems for different frequencies ofcompounding变为calculate the solution for time value of moneyproblems with different frequencies of compounding,考纲描述变化。

Reading 7、Reading 8和Reading 9:描述性统计的内容。
Reading 10和Reading 11是推断性统计的内容。
Reading 12其实就是一个理论具体分析运用的过程,为分析师们提供了一些可实操重要指标。
CFA协会一篇针对投资风格的文章深入浅出地讲解了资产组合中如何通过收益率风险的分布情况对冲TailRisk(尾部风险),作者调用了1981-2010这20年G7(加拿大、法国、德国、意大利、日本、英国和美国)国家主板市场股票收益率情况。
标准差、夏普比率大家都不陌生,当然真正的投资组合管理不会只让你看考虑收益率统计值和风险调整收益这么简单,实际中我们更需要发现问题,并解决(InvestmentStrategy).我们在量化中学的偏度(Skewness)这个概念很少有人用到,实际上这个概念在解读历史收益率分布时非常有用,因为它决定了我们投资组合的尾部风险(TailRisk),更决定了我们下一步hedge的策略。

1. Over the past 240 months, an investor’s portfolio had a mean monthly return of 0.79%, with a standard deviation of monthly returns of 1.16%. According to Chebyshev’s inequality, the minimum number of the 240 monthly returns that fall into the range of −0.95% to 2.53% is closest to:
Holding period yield (HPY)=(ending value/begin value)-1
Bank discount yield (BDY)=(discount/face value)x(360/days to maturity) simple interest
Money market yield (MMY)=(discount/price)x(360/days to maturity) simple interest

CFA一定量分析难点解析
![CFA一定量分析难点解析](https://img.taocdn.com/s3/m/7ebfaf7e83c4bb4cf7ecd15a.png)
高顿CFA导读:CFA考试与很多考试不同的地方在于,其一二三级的考试科目内容级别相同,不同的地方在于其考试难度和分值占比。
其中Quantitative Methods(定量分析)在CFA Level I中占到了12%,也就是说在总共240题中,定量分析占到了将近30题,这也是考生绝对不能掉以轻心的科目。
定量分析就是以数量工具测算投资组合关联性,概率统计,为设定合理理性的投资规划提供技术支撑。
在一级二级考试中是考试占比比较大的考试科目,主要是计算方法的考核,记得住公式就肯定可以做对题。
定量分析的学习内容分布在CFA官方教材第一本和Study Notes Book One中,对于定量分析的学习必须在一级阶段打好基础,为了接下来的二三级考试铺好基石,这就需要注意定量分析的一些重点难点。
2018年6月CFA课程正式开售了CFA早鸟课程可点我咨询CFA一级定量分析难点01.难点一:如何计算复杂的现金流?复杂的现金流其实难度不高,就是把几种简单的现金流综合在一起加以计算,突破此类习题的关键点不在于做大量习题,而在于总结。
以下是做题的关键点,每做一道现金流的题目,我们可以按照这个步骤去归纳知识点。
1、画出时间轴,根据时间轴确定是那几个基本现金流组合(折现or中值or年金or永续),并标出所给数据。
2、根据时间轴,自己归纳所属的形式(pension模式,债券模式,股票模式,大学教育理财模式)。
3、使用金融计算器对时间轴标出的数据进行计算。
考题中折现+年金的组合方式较多,这里要多做归纳和总结。
要记住,年金的折现并非是折现到T年而是折现到T-1年。
4、千万不要大量做题,搞懂课本教材中的课后习题中几个典型的例题就好,那几个例题基本上属于较难的习题了。
02.难点二:几何平均数和调和平均数。
几何平均数其实就是假设按照一个固定的平均增长利率,不停的每年增长。
比如银行存款利率第一年4%,第二年3%,第三年2%,第四年1%, 那么这四年下来我把钱第一年存进去取出来,第二年存进去取出来。
