  CFA考试难不难,有哪些攻略?从题海战术里走出来朋友们(cfa报考条件最新更新了),都应该有了解过这种学习方法很有突破性。这其实就是一个熟能生巧事情,即时可能你对某个CFA备考知识点不理解,剥掉CFA考试题干外壳,其实都是同一个套路,最后能够轻松掌握考试难点。

  比如,我们在CFA考试备考的时候(cfa是什么证书,CFA是你黄金人生),在接下来几周里,我们会陆续发放三个级别高频问答,希望对大家CFA考试备考有所帮助。今天二级放上数量错题本,大家一起来看看这些题都会做吗?
  
  CFA考试精选问答1
  
  CFA考试题干
  
  A factor associated with the widespread adoption of algorithmic trading is increased:
  
  A. market efficiency.
  
  B. average trade sizes.
  
  C. trading destinations.
  
  答案解析
  
  C is correct.
  
  Global financial markets have undergone substantial change as markets have fragmented into multiple trading destinations consisting of electronic exchanges,alternative trading systems, and so-called dark pools.
  
  In such an environment,when markets are continuously reflecting real-time information and continuously changing conditions, algorithmic trading has been viewed as an important tool.
  
  解题思路
  
  这题考察是算法交易内容(CFA考试报名费用公布上涨了)。考试题目问是,下面哪个现象增加是导致算法交易广泛使用原因?
  
  A选项,市场有效性增加。这个其实并不是导致算法交易广泛应用原因,而是算法交易广泛应用所导致结果。比如我们使用高频交易,可以快速获得信息,对市场做出反应,可以快速纠正整个市场价格出现错误定价现象,得到一个更好市场有效性。
  
  B选项,交易规模增加。这个也是算法交易广泛应用所导致结果。因为有了高频交易之后,交易频率更高,导致市场流动性在增加,从而导致交易规模增加。
  
  C选项,交易地点增加。正是因为交易地点越来越多,一只股票可能会在多个交易所进行交易,所以对于信息处理要求在进一步增加,所以算法交易才会被广泛使用。所以正确答案是C选项。
  
  CFA考试易错点分析
  
  这道题很多人都容易出错,确实考也是比较细CFA备考知识点。这道考试题目有个陷阱就是,考是导致算法交易广泛使用原因,而不是算法交易广泛应用所导致结果。这里就很难进行区分,也是很多人疑惑点。Fintech考试题目都是一些文字概念题,也是2019年新增CFA备考知识点,对于这部分内容还是需要再去浏览一遍讲义进行理解记忆。
  
  CFA考试精选问答2
  
  CFA考试题干
  
  If an omitted variable is correlated with variables already included in the model,coefficient estimates will be biased and inconsistent and standard errors will also be inconsistent. Is this Statement correct?
  
  A. Yes.
  
  B. No, because the model’s coefficientestimates will be unbiased.
  
  C. No, because the model’s coefficientestimates will be consistent.
  
  答案解析
  
  A is correct.
  
  Changis correct because a correlated omitted variable will result in biased andinconsistent parameter estimates and inconsistent standard errors.
  
  解题思路
  
  如果遗漏了一项跟已有变量相关变量(CFA考试时间和费用多少),那么说明这个建好模型残差项包含了跟自变量有关系那个变量,那么也就是自变量和残差项相关,就不满足模型前提假设了,才会引发之后一系列影响。所以这道考试题目考其实是model Misspecification,并不是多重共线性。
  
  CFA考试易错点分析
  
  这道考试题目很多CFA考生都会自动联系到多重共线性情形,所以很容易选错答案。但其实这题只是说遗漏了一个重要变量,但又还没有达到多重共线性所要求相关系数大于0.7那么重要,所以如果考察是多重共线性,那么在考试题目中一定是会有相对应描述。
  
  所以这题其实考并不是违反三个假设,而是model Misspecification第一条,重要变量遗漏。这里要注意区分,不要弄混了。
  
  CFA考试精选问答3
  
  CFA考试题干
  
  Varden answers both questions correctly and says he wants to check two more ideas. He believes the following:
  
  ROE is less correlated with the dividend growth rate in firms whose CEO has been in office more than 15 years, and
  
  CEO tenure is a normally distributed random variable.
  
  If Varden’s beliefs about ROE and CEO tenure are true, which of the following would violate the assumptions of multiple regression analysis?
  
  A. The assumption about CEO tenure distribution only.
  
  B.The assumption about the ROE/dividend growth correlation only.
  
  C. The assumptions about both the ROE/dividend growth correlation and CEO tenure distribution.
  
  答案解析
  
  C is correct.
  
  Multiple linear regression assumes that the relationship between the dependent variableand each of the independent variables is linear.
  
  Varden believes that this is not true for dividend growth because he believes the relationship may be different in firms with a long-standing CEO.
  
  Multiplelinear regression also assumes that the independent variables are not random.Varden states that he believes CEO tenure is a random variable.
  
  解题思路
  
  对于CFA考试第一条,他认为,CEO超过15年公司股息增长率与ROE关系较弱。说明股息增长率与ROE关系不稳定,并且取决于CEO在任时长,那么这就违背了自变量与因变量之期间呈现线性关系假设。
  
  对于CFA考试第二条,他认为,CEO任期是正态分布随机变量。那就违反了自变量不是随机变量这个假设。
  
  所以综上所述,以上两条都会违反多元回归分析假设。
  
  CFA考试易错点分析
  
  这道考试题目大家出错比较多,主要是因为没有看懂考试题目在说什么。对于回归假设这一CFA备考知识点,很多CFA考生很容易遗忘,当放在case题里面考察时候,一下子就反应不过来了。
  
  除了这题,其实很多题都会建立在回归检验假设上来出题,并不是只考察单一CFA备考知识点。所以对于回归分析前提假设,我们还是要做到牢记于心,当遇到不知从何下手考试题目,也许这就是一个突破点(cfa一级考试CFA科目最新更新)。
