$$ n= sample \quad size $$. 1. $$ { r }_{ f }=risk-free\quad rate\quad of\quad return $$ A data set with negative skew has more values to the extreme left side of the distribution, and positive skew indicates the same occurring to the right side of the scale. Watch the sessions on-demand. Accessed July 26, 2020. Successful candidates report spending about 300 hours studying for each level, ranging from 303 hours for the CFA Level I exam to 328 for the CFA Level II exam and to 344 for the CFA Level III exam. $$ { \mu }=standard\quad deviation\quad of\quad the\quad population $$ You won’t often have to do the formulas written out by hand, but be familiar with them because the logic here applies to many other applications through this topic area. Be careful in exam questions involving these equations, because sometimes you will be given the portfolio risk expressed as the Standard Deviation or as the Variance. You will need to be comfortable discounting the Present Value and Future Value of cash flows for individual and ongoing payments in the exam. The kurtosis of a normal distribution has a value of 3, so the excess Kurtosis is calculated as: $$ Once you have input all figures you have, you press the CPT button and then the parameter button you want to calculate. It is widely accepted that a sample of size of at least 30 is usually enough to make the sample representative, but that can vary depending on the skewness of the sample distribution. A core tenet of statistics is using samples of data to find information about the entire population of a data set. $$ Weighted\quad Mean=\sum _{ }^{ }{ { X }_{ i }{ W }_{ i } } $$ need to be comfortable discounting the Present Value and Future Value of cash flows for individual and ongoing payments in the exam 2. The output of this method is a distribution of the potential outcomes far more detailed than what a simple linear model could project. Dont try it drewnelson, we all know it, don't we? 1 In return, it issues credit to the banks' reserves. This distribution is appropriate for small samples when the population variance is unknown. 2 thoughts on “CFA Level II: Quantitative Methods, ANOVA Table” Richard says: March 6, 2013 at 12:37 Jérémie, two copy-paste errors: the second SST (2nd formula) is rather “RSS” and the third SST (3rd formula) should be “SSE” , I guess. Tag Archives: quantitative easing. When the population variance is known, we can use the more accurate z-score to determine the confidence interval instead of the student’s t-score, but the Central Limit Theorem allows us to also use the z-score when the sample size is large enough. Computing technology has introduced new methods of performance forecasting, including Monte Carlo Simulation. The sum of all conditional probabilities for an event adds up to the non-conditional probability of that event, if the conditions are mutually exclusive. The Total Probability rule is similar to the addition rule but deals with the combination of conditional probabilities to create the entire probability of an event occurring. Register a user account to print out study notes and all practice questions. Don’t forget to input the interest amount in decimals, so that 5% is entered as 0.05. By Usman Hayat, CFA During the global financial crisis, excessive debt was the principal disease. Subject 6. Quantitative easing (QE) has not ended in the United States, but rather its growth has stopped, for at least a time. One way to calculate potential outcomes using a Bernoulli approach is known as a Binomial Tree: In this case, each final outcome is seen as successive iterations of Bernoulli events. The degrees of freedom is calculated as n-1. A good way to catch potential errors when calculating the values of a binomial tree is that each column (a specific point in time) should add up to a probability of 100%. The Central Bank creates money to buy government securities from the market in order to lower interest rates It refers to how symmetrical a data’s distribution is relative to a completely symmetrical normal distribution. Your calculator has built-in functionality for PV and FV equations using the row of buttons labeled “N’, “I/Y”, “PV”, “PMT”, and “FV”. This technique is generally implemented when the Standard monetary policy has become ineffective in tackling low inflationary or deflationary situations. Parametric tests involve any testing where the given parameter follows a specific distribution. To input a value, you type in the number for the value and then press the corresponding value’s button (i.e., to input 10,000 as the PV, you type in 10000, then press the “PV” button). It is also important in the first two levels of the CFA exam, representing 12% in Level 1 and 5-10% in Level 2. Megan E. Greene, Global Chief Economist Manulife Investment Management There are two classifications of statistical tests that you will need to know, Parametric and Non-Parametric. The components of the interest rate (risk free, inflation, default risk, and other risk premiums) October 14, 2019 in CFA® Program by Michael Abbe. 1. This posits that a data sample will have a mean and variance that approach the mean and variance of the population it represents as the sample size becomes sufficiently large. Global CFA ranking: Know where you stand at all times vs. other candidates worldwide. $$ d=\frac { r }{ \left( 1+r \right) } $$ Introduction. $$ X=sample\quad mean $$ Return & 10\% & 6\% \\ The Correlation value ranges between -1 and 1. Quantitative easing. This course is ideal for you if you are enrolled in Level 2 of the CFA program. Bayes’ Formula is a method of calculating an updated probability of an event occurring, given a set of prior probabilities. $$ Harmonic\quad Mean=\frac { N }{ \sum _{ }^{ }{ \frac { 1 }{ { X }_{ i } } } } $$ A rising gold-crude ratio (MA50) is an indicator of weak global and US growth, disinflation and an upcoming Quantitative Easing. Hypothesis testing is a method of determining the statistical significance of a given data point in a distribution. The higher the Sharpe Ratio of a portfolio, the more excess return you are getting for each additional unit of risk. Quantitative Easing (QE) is an expansion of the Open Market Operations of the Central Bank. Now we’ll calculate these values for the following returns data: $$ $$ s=standard\quad deviation $$ Quantitative easing … By David Nelson, CFA CMTAfter years of taking a back seat to large cap secular growth small caps have suddenly exploded higher catching the eye of investors. The quantitative easing recently announced by the Bank of Japan may benefit investors who hold Japanese equities, but Ron Rimkus, CFA, sees the classic makings of … $$ n = number \quad or\quad discounting\quad periods\quad per\quad year $$ Either of these conditions would be referred to as the distribution having “fat” tails. The central bank buys bonds on the open market with money created out of thin air. Contractionary and Expansionary Monetary Policies and the Neutral Rate. It also turned out to be the principal cure. Quantitative easing works through open-market trading operations at the regional Federal Reserve Bank of New York. Quantitative Easing Reality Check. CFA is hard for everybody; you are not special During my undergraduate and honours degrees I studied Computer Science. Using this discount rate, $1 one year from now is worth $0.95 today. $$ $$ W=percentage\quad weight $$, The Arithmetic Mean of the numbers \( { \left\{ 1,2,3,4 \right\} }\) is: \( \frac { 1+2+3+4 }{ 4 } =2.5\). The Safety First Ratio is expressed as the excess return of the portfolio (expected returns – threshold returns) divided by portfolio risk (standard deviation): $$ SF\quad Ratio=\frac { E\left( { R }_{ p } \right) -{ R }_{ L } }{ { \sigma }_{ p } } $$. They incorporate a trade-off of value range and confidence, such that the smaller the area in which the value is believed to exist, the lower the confidence that it is actually there. Quants (and machine learning researchers) are typically assumed to be intelligent and many possess an above-averag… $$ PV=Present\quad Value $$ $$ { \sigma }_{ 0 }=Hypothesized\quad mean\quad of\quad the\quad population $$ But on negative rates - the topic markets are most interested in - we suspect policymakers will keep their cards relatively close to their chests The Weighted Mean of a portfolio with the following assets is: $$ 1. The Standard Deviation is simply the square root of the variance. An instance where this could be necessary is when there are significant outliers that could cause the mean value of a dataset to be unrepresentative of the data. A similar issue that you’ll have to deal with involves ongoing cash flows such as annuities and perpetuities. In quantitative easing (QE), a central bank buys any financial assets to inject money into the economy. Both involve finding the current value of a series of cash flows, just that an annuity continues for a certain period of time and a perpetuity never ends. This approach gives a much more limited set of outcomes than the Monte Carlo, but has the benefit of being based on observed market events rather than projected simulations. It is important to understand the nature of covariance, but you should not have to calculate this formula by hand on the exam. Skewness is another way to describe the distribution of a data set. So, the Fed has to monetize the debt via quantitative easing. Caught off guard hiding in the safety of large companies with bigger and stronger balance sheets professional and retail investors are being forced to rethink portfolio alignment and… Otherwise, we fail to reject the null hypothesis. $$ x = sample \quad mean $$ Did you miss the 73rd CFA Institute Annual Virtual Conference? Quantitative Methods are covered in Study Sessions 2 and 3, which have a combined weighting of 12% on the Level 1 CFA exam. … $$ $$ { \sigma }_{ { R }_{ a },{ R }_{ b } }=\sum _{ }^{ }{ P\left( { R }_{ a } \right) \left[ { R }_{ a }-E\left( { R }_{ a } \right) \right] } \left[ { R }_{ b }-E\left( { R }_{ b } \right) \right] $$. The formula would look like this: $$ PV=\frac { $1 }{ \left( 1+.05 \right) } =$0.95 $$. The t-distribution has an important parameter known as the Degrees of Freedom. posted Jan 26, 2015, 11:33 PM by Mikin Shah AMERICA'S Federal Reserve surprised markets in December by starting to "taper" (ie, gradually reduce) its programme of monthly purchases of government and mortgage bonds—a process known as "quantitative easing", or QE—from $85 billion a month to $75 billion. It is an expansionary monetary policy whereby Central bank purchases predetermined amounts of Government bonds or other financial assets for stimulating the economy. Fed QT vs the S&P500: This next chart shows how the S&P500 has traded as the Fed began "balance sheet normalization" - if you think balance sheet normalization is not tightening then this chart should prompt some contemplation and reflection. This involves the central bank buying financial assets from the commercial banks using the money it creates newly. 3. 5. Quantitative easing efforts are looking high from other central banks. A normal distribution with unknown variance: $$ CI=X\pm { t }_{ \frac { \alpha }{ 2 } }\ast \frac { S }{ \sqrt { n } } $$. "New Framework for Strengthening Monetary Easing: "Quantitative and Qualitative Monetary Easing with Yield Curve Control," Pages 1-2. This is compared to the other common technique of Historical Simulation. During my undergraduate and honours degrees I studied Computer Science. Covariance is the degree to which two variables move in sync with one another. The shape of the distribution is dependent on the number of degrees of freedom. Trusted by thousands of CFA and FRM candidates each year. A common way (that will definitely appear multiple times on the exam) of analyzing the probability distribution of a data sample is to use the Student’s T-Distribution. Bloomberg Opinion. Source: ING estimates . Since both P(A) and P(B) include the possibility of both events occurring, we subtract the probability of both so that it’s not double-counted. What is the weighting of this topic in the CFA exams? We must use the absolute values because a sum of the deviations from the mean in a data set is always 0. $$ PV=\frac { FV }{ { \left( 1+\frac { r }{ n } \right) }^{ n\ast t } } The CFA Institute has kept track of pass rates dating back to 1963... 3,000 CFA® Practice Questions – QBank, Mock Exams, and Study Notes, 3,000 FRM® Practice Questions – QBank, Mock Exams, and Study Notes. Without the Fed soaking up trillions in Treasuries, the glut of bonds on the market would crash the price and push interest rates up – something the Federal Reserve cannot allow to happen. $$ n= sample \quad size $$. At each point in time, the stock goes up or down. The Multiplication Rule applies to the joint probability of multiple events occurring. $$ PV\quad Annuity\quad Due=\frac { \left( 1-{ V }_{ n } \right) }{ d } $$ $$ \frac { 4 }{ \frac { 1 }{ 1 } +\frac { 1 }{ 2 } +\frac { 1 }{ 3 } +\frac { 1 }{ 4 } } =1.92 $$. 8 Ways to Improve your Writing Skills for the CFA® Level III Exam, CFA® Level I Exam Study Plan offered by AnalystPrep, CFA® Program Course offered by AnalystPrep, https://www.youtube.com/watch?v=uu7ZmnSlQEs, https://www.youtube.com/watch?v=PJbRtIVGdaI, 1 means that the two variables move in sync. Non-parametric testing does not involve making any assumptions about the distribution of the parameter being studied. Two of these methods that you need to know are Kurtosis and Skewness. Download study notes in a PDF file immediately. When looking at data sets, there are different ways to categorize the distribution of the data. $$ S=sample \quad standard \quad deviation $$ $$ P\left( { E }_{ j } \right)=prior\quad probabilities $$ $$ Shortly after graduating I found myself working as a quantitative analyst. The tree lists all possible outcomes for this stock, and the probability of each final outcome is the multiplied product of the probability at each step along the way. $$ PV\quad Perpetuity=\frac { C }{ r } $$ In December 2012, this ratio was still around 19. To use these for a problem, you input the value of all the parameters that you know and then have the calculator compute the missing value. $$ n= sample \quad size $$. Where do central banks get the funds to purchase the banks' securities? The formulas you need to know are: $$ Arithmetic\quad Mean=\frac { \Sigma { X }_{ i } }{ N } $$ For this article, we will look at Quantitative Methods for CFA Level I, one of the most useful topic areas that's used throughout CFA Level I. In recent years, many central banks have undertaken unconventional monetary policy to stimulate their economies, mainly through large-scale asset purchase programs (LSAPs) often referred to as quantitative easing (QE). The joint probability of both events happening (P(AB)), is the conditional probability of A, assuming B occurs (P(A|B)), times the probability of B (P(B)). $$ MAD=\frac { |0.1-0.073|+|0.07-0.073|+|0.05-0.073| }{ 2 } =0.027 $$ For the same set of numbers, it is always the case that: Arithmetic Mean > Geometric Mean > Harmonic Mean. $$ N=number\quad of\quad observations $$ The t-distribution is symmetrical about its mean and has thicker tails than the normal distribution. $$ C\quad is\quad amount\quad of\quad each\quad payment $$. CFA® and Chartered Financial Analyst® are registered trademarks owned by CFA Institute. There are two types of errors that could occur when running a hypothesis test. As the number of degrees of freedom increases, the distribution becomes more closely gathered around the mean. The Variance is the average of the squared deviations from the mean, and the formula to calculate this for a sample of data looks like this: $$ { \sigma }^{ 2 }=\frac { \Sigma { \left( { X }_{ i }-\bar { X } \right) }^{ 2 } }{ n-1 } $$ The level of significance (α) represents the probability of making a type 1 error. $$ Sharpe\quad Ratio=\frac { \left( { r }_{ p }-{ r }_{ f } \right) }{ { \sigma }_{ p } } $$ Another important formula related to the previous metrics is the Sharpe Ratio. Quantitative Easing (QE) is like expansionary monetary policy on steroids. It’s often impossible to gather all of the data of a population, so we rely on representative samples and try to make sure they properly represent the population from which they are drawn (like polls given to small groups of people to represent a whole state or country). by Daniel R. Amerman, CFA. For this reason, if you wanted to run a test focused on the median of a dataset instead of the mean you would run a non-parametric test. $$ FV=Future\quad value $$ Achieving a return less than a specified required return is known as Shortfall Risk. The test statistic for the hypothesis testis is calculated as follows: $$ Test\quad statistic=\frac { Sample\quad statistic-Hypothesized\quad value }{ Standard\quad error\quad of\quad the\quad sample\quad statistic } $$. Portfolio\quad Weight & 60\% & 40\% \\ $$ \left( 0.6\ast 0.1 \right) +\left( 0.4\ast 0.06 \right) =0.084 $$, The Geometric Mean of the numbers \( \left\{ { 1,2,3,4 } \right\} \) is: What is Quantitative Easing? Shortly after graduating I found myself working as a quantitative analyst. Petr Krpata, CFA Downgraded forecasts and more quantitative easing are likely to be the major headlines from the Bank of England this week. $$ Geometric\quad Mean={ \left( { X }_{ 1 }\ast { X }_{ 2 }\ast \dots \ast { X }_{ n } \right) }^{ \frac { 1 }{ n } } $$ Following my first post about the Level II and specifically correlation, I am now moving on to the main topic if this year’s curriculum: multiple regression. The Mean Absolute Deviation is a measure of the average of the absolute values of deviations from the mean in a data set. A confidence interval is the range of values in which a statistician believes that a certain population parameter lies. $$ { \sigma }_{ 0 }=Hypothesized\quad mean\quad of\quad the\quad population $$ A Bernoulli Random Variable is one that can have only two outcomes. However, it can also be taken up by those doing majors in Finance or working in the investment management industry. Since the probability of both events happening is less than the odds of either one individually, the joint probability will always be lower than either input. Fed Would Need to Double Quantitative Easing to Keep Pace With US Debt December 2, 2020 by SchiffGold 0 0 The US government is increasingly relying on the Federal Reserve to prop up the Treasury market and absorb the trillions of dollars in bonds it’s issuing in … Here are the calculations that you need to know: There are several methods of calculating the average value for a set of numbers as laid out in the curriculum. $$ { s }=standard\quad deviation\quad of\quad the\quad sample $$ A simple example of this application is if you needed to determine how much you would pay today to receive $1 in one year, assuming your required rate of return was 5%. The correct hypothesis test for a normal distribution of the random variable is the Z-test, which is calculated as: $$ z-statistic=\frac { X-{ \mu }_{ 0 } }{ \frac { \sigma }{ \sqrt { n } } } $$ For hypothesis testing to show whether the population correlation coefficient equals zero (absence of linear relationship between two variables), we use the t-statistic: The decision rule is to reject the null hypothesis (⍴=0)/to uphold the alternative hypothesis (⍴≠0) if t is greater than the critical value from the t-distribution table. $$ P\left( { E }_{ i }|A \right) =\frac { P\left( { E }_{ i } \right) P{ \left( A|{ E } \right) }_{ i } }{ \Sigma P\left( { E }_{ j } \right) P\left( { A|E }_{ j } \right) } $$ You should expect, however, to be calculating correlations, which use the following formula: $$ Correlation\left( { R }_{ a },{ R }_{ b } \right) =\frac { Covariance\left( { R }_{ a },{ R }_{ b } \right) }{ StdDev\left( { R }_{ a } \right) \ast StdDev\left( { R }_{ b } \right) } $$. $$ Policy options open to the European Central Bank to rein in further increases in the value of the euro include cutting interest rates, signaling more quantitative easing or publicly advising against allowing it to rise, a tactic used by former ECB chief Mario Draghi. With QE, central banks print money to buy bonds. There are three categories of kurtosis, as illustrated in the graph below: A data set would be described as Mesokurtic if it closely resembled a normal distribution, Leptokurtic if it was more tightly clustered around the mean, and Platykurtic if it is more widely distributed. A normal distribution with a known variance: $$ CI=X\pm { z }_{ \frac { \alpha }{ 2 } }\ast \frac { \sigma }{ \sqrt { n } } $$. $$ n=term \quad of \quad annuity $$ The CFA quant section is the most mathematical and formula driven. Quantitative easing as we know it is a kind of monetary policy use by the central bank of a country to stimulate the economy when other conventional methods are not working. Another important component of hypothesis testing is the P-Value. The formula to calculate the covariance of two assets (a and b) in a portfolio appears as follows. There are several types of distributions you will need to understand, and this includes understanding a few common kinds of randomly distributed variables. There are several concepts involving calculating probabilities you need to know. A key difference between QE and normal expansionary monetary policy is that with QE central banks also buy other bonds besides short-term government bonds; they buy corporate bonds and long term government bonds. In that approach, a projected portfolio is run through actual historical situations to see how it would have performed. The formula for calculating a t-statistic is: $$ t=\frac { x-\mu }{ \frac { S }{ \sqrt { n } } } $$ Over 5,700 practice questions that cover the entire CFA curriculum.
