...and accuracy of the theories used by DFA, especially the value premium and the size premium where almost all of their funds are based upon. The company used for this report is Dimensional Fund Advisors, which is an investment fund company. The source of information that is used is from websites and some journals. The main finding in this report is that DFA focusing their investment in small cap stock, as small stock tends to outperform large stock. To conclude, this report will provide evidence on the usefulness of these theories to increase return of DFA’s funds as well as recommendations about changes in strategy that will enhance the performance of DFA overall. Introduction Dimensional Fund Advisors is an investment company that uses its strategy based on academic research as well as related theories. It is based in Santa Monica, California and founded in 1981 by Booth and Rex Sinquefield. They work together with advocate of the efficient market hypothesis, indicating a relatively strong belief in this theory and thus in efficient markets. DFA believe that skilled traders have the capability to pitch in to the fund’s profits, although the investments are inherently passive. Additionally, they also adjust their strategy to new findings in the field. This report will discuss the next step that DFA should implement in order to perform better compared to the other managed funds. DFA’s Business Strategy DFA’s business strategy is based on the core concept that markets are “efficient”...

...Dimensional Fund Advisors 2012 Background, Principle and Strategy of DFA Dimensional is a different kind of investment firm headquartered in Austin, Texas with regional offices in Amsterdam, Berlin, London, Santa Monica, Sydney, and Vancouver now (DFA 2012) which was founded in 1981 by David G. Booth and Rex Sinquefield, both graduates of the University Of Chicago Graduate School Of Business. The underlying principle of DFA is that the stock market was “efficient” which is, on one could beat the market consistently except by luck during some periods. The founders also believed that academic research and the ability of skilled traders could contribute to a fund’s profits even when the investment was inherently passive. At the first stage, DFA was aiming single investment fund that consisted with small stocks which fit its position in the market as a passive fund. The initial clients were major for tax-exempt institutions such as government, union pension funds and charities and etc. With the time going, DFA pursued individuals while through the intermediaries known as RIAs. Although with the low turnover, low transaction costs and diversification, DFA still could make reasonable profits by charging a moderate advising fee and developed rapidly. DFA is an outstanding investment firm doing the investment based on precise academic research and strict trading strategy which will both be discussed later. Over the years, DFA have translated financial research into real world investment...

...Dimensional Fund Advisors 1. What are the primary academic finds that DFA are trying to exploit in their funds? Dimensional Fund Advisors Investment (DFA) uses two primary academic strategies. The first is Size Effects based on the finding of Rolf Banz. Banz’ research found that small stocks consistently outperformed large stocks over the entire history of the stock market from 1926 through the late 1970s. The second academic strategy DFA used was the Book to-Market effect based on the finds of Fama/French1992 paper titled “The Cross-Section of the Expected Stock Returns”. In 1993 Fama/French expanded the research in the a titled “Common Factors in the Expected Returns of Stocks and Bonds” that is known as the “Fama-French Three-Factor Model” Studying the company’s size or the book-to-market ratio may shed light on exposure to sources of systemic risk not captured by the CAPM beta, Fama and French developed the Three Factor Model believing that small stocks may be more sensitive to changes in business conditions and that these variables may capture sensitivity to macroeconomic risk factors. Also, using international data collected by Morgan Stanley Capital International, Fama and French found that high book-to-market stocks outperformed low in almost every country studied. Fama and French also found that in certain years value portfolios were outperformed by growth portfolios across a wide array of countries. Investor cannot expect to lower their risk by diversifying their...

...HMC’s method of portfolio allocation consist of: - using the CAPM model to make long term assumptions about real return, risk, and correlations of the twelve asset classes it has created and - using the Mean Variance Optimization method (MVO) to find the set of portfolios that would provide the maximum expected return for a given level of risk and, conversely, the minimum risk for a given level of expected return (“the efficient frontier” of possible combinations of asset classes). To infer variance and covariance of each asset class and estimate all the necessary parameters for the CAPM, HMC examines historical data, asks the opinion of consultants and investment management firms and uses the current market conditions to adjust its assumptions. As the true values are unknown, it is easy to make mistakes that will impact the MVO, which has the disadvantage of being very sensitive to changes in its inputs (small changes cause significant output movement and can result in having an inefficient portfolio). As emphasized in Exhibit 11, we note that HMC, given approximately the same level of risk, has the same expectation for domestic and foreign real returns. This implies that the equity risk premium (E(ri)-rf ) for both asset classes is the same. It suggests that HMC has the same risk aversion when it comes to invest in a foreign asset or a domestic one, it expects the markets to evolve similarly. Due to its simplicity of utilization, The MVO method is very attractive for...

...Monday, January 27th, 2014 Case Summary #1 Dimensional Fund Advisors The California based investment and advisory firm, Dimensional Fund Advisors, was founded in 1981 by Chicago University students. The founders created DFA based on academic findings that stocks with small market capitalization outperformed the market and large cap stocks over a long period of time. DFA focused on selling investment funds that incorporated a bunch of small cap stocks from major stock exchanges like the NYSE. Their initial small cap funds were devised by ranking the market cap of stocks on the NYSE, AMEX and NASDAQ from top to bottom. From there, they split the ranked stocks into ten groups called deciles. They then sold different funds that would replicate buying stocks from the bottom 5 deciles. Over the years, they became one of the biggest small cap stock owners, owning over 3% of stocks in the bottom two deciles. DFA bought stocks in large blocks. They constantly looked for bargains on the market and bought in bulk. They only accepted deals that would save them several percentage points below the current market value of securities they wanted to purchase. They did not rely on any fundamental analysis in their stock purchases. They just focused on buying the small cap stocks that fell into their deciles and made sure that they didn't buy too many stocks that fell into the same industry or sector. DFA strongly believed that their funds offered enough added value to include a small...

...Would you invest in DFA? Yes due to steady returns provided by the company and as investors are generally past performance chasers, one has no reason not to invest in DFA. The company was founded on a sound investment style based on its core belief in sound academic research, passive fund management. Until almost the end of the 20th century DFA had found a way to make money actively with a passive investment strategy. But looking forward, according to me it needs to evolve with the times and look for questions regarding its own strategy and its evolution with the times and the questions facing the financial future. As highlighted by the boom in the I.T sector towards the end of the last century that DFA missed out on completely, DFA on principle is always poised to miss out on new technology companies, as they intrinsically have low book to market value. Also my another objection to DFA’s selection of small cap stocks only is that these category of companies are among the worst hit companies during a financial crisis because of their limited access to credit and most of these companies don’t survive a major recession. Even some proponents of the efficient market hypothesis have argued that due to DFA and similar companies investing in this particular style, this style’s edge had been eroded. Lastly many prominent academicians and financial institutions have called into question the efficacy of the efficient market theory due the financial bubble created in...

...Dimensional Fund Advisory was an investment firm composed of small stocks. This firm believed in the efficient market theory. They believed in diversification to reduce firm specific risk, but they did not rely on indexing or passive investment. They believed in the “small stock effect”: small stocks provide greater returns than large stocks for the same amount of volatility. Their strategy was to invest in small cap stocks based on deciles. They started with the “DFA 9-10 Strategy”, in which they invested in companies chosen from the 9th and 10th deciles of the NYSE, the American Stock Exchange and the NASDAQ. Later, they added the “DFA 6-10 Strategy” and the “DFA 6-7-8 Strategy”. The implemented an active strategy by searching for attractive purchases. They screened stocks. They looked for impatient or desperate sellers. They rejected stocks that were expected to divulge news soon. They questioned themselves about the seller and the nature of the sells. Once they ensured that sellers were not selling because they had adverse information or negative private information about the stock, they then negotiated for a good price. DFA had an additional competitive advantage by creating trading efficiencies to reduce transaction cost. They charged an active management fee that was higher than passive management fees, but smaller than what the average active manager charges. It was part of their core beliefs to offer low transaction costs. They traded in blocks to extract a discount...

...After completing Lab 4 Acceleration Due To Gravity I can conclude that using a direct method (free falling activity) in obtaining acceleration is more precise than compared to the indirect method (pendulum swing activity). Thusly when I compared my results of each experiment, the free falling measurements were not so great, but closer to the earth’s acceleration. For example, my last measurement of the free falling activity was approximately 985.11 cm/s^2, which was very close to the earth’s acceleration. On the other hand my last measurement on the pendulum swing activity my last measurement was 2196.14 cm/s^2, which was very off from the earth’s acceleration. It is possible to assume errors in my calculations may had alter any of my measurements. Also possible errors in the experiment could have also altered my results. I can honestly say it is not that simple to obtain multiple measure close to the earth’s average. This experiment was overall simple to conduct, but obtaining really good results compared to the earth’s average is the challenge. I really enjoyed conducting this experiment using two different methods to obtain acceleration. My favorite activity was the free falling activity, because I actually obtain one very good measure. These experiments were pretty simple once I got the hang of using the equipment. I thought this experiment was quite interesting looking at my results and comparing them to the average. I had no dislikes on these experiments. Overall this...

...SIMILITUDE AND DIMENSION ANALYSIS DEFINITION AND USES OF SIMILITUDE • Similitude means similarity • it impossible to determine all the essential facts for a given fluid flow by pure theory alone • we must often depend on experimental investigations. • we can greatly reduce the number of tests needed by systematically using dimensional analysis and the laws of similitude or similarity. • For these enable us to apply test data to other cases than those observed. • we can obtain valuable results at a minimum cost from tests made with small-scale models of the full-size apparatus. The laws of similitude enable us to predict the performance of the prototype, which means the full-size device, from tests made with the model. for example, we might study the flow in a carburetor in a very large model. • A few examples of where we have used models are – ships in towing basins, – airplanes in wind tunnels, – hydraulic turbines, – centrifugal pumps, – spillways of dams, – river channels and the study of such phenomena as the action of waves and tides on beaches, – soil erosion and – transport of sediment. GEOMETRIC SIMILARITY • geometric similarity means that the model and its prototype have identical shapes but differ only in size. • the flow patterns must be geometrically similar. If subscripts p and m denote prototype and model, respectively, we define the length scale ratios as the ratio of the linear dimensions of the prototype to the corresponding dimensions in the model. = ...

...MEASUREMENT AND UNITS & DIMENSIONS Synopsis : 1. Every measurement has two parts. The first is a number (n) and the next is a unit (u). Q = nu. Eg : Length of an object = 40 cm. 2. The number expressing the magnitude of a physical quantity is inversely proportional to the unit selected. 3. If n1 and n2 are the numerical values of a physical quantity corresponding to the units u1 and u2, then n1u1 = n2u2. Eg : 2.8 m = 280 cm; 6.2 kg = 6200 g 4. The quantities that are independent of other quantities are called fundamental quantities. The units that are used to measure these fundamental quantities are called fundamental units. 5. There are four systems of units namely C.G.S, M.K.S, F.P.S and SI 6. The quantities that are derived using the fundamental quantities are called derived quantities. The units that are used to measure these derived quantities are called derived units. 7. The early systems of units : Fundamental Quantity System of units C.G.S. M.K.S. F.P.S.

...ci3.1 BLOCK DIAGRAM Fig 3.1 block diagram of the vibration measurement system The above figure shows the block diagram of the vibration measurement system. The different blocks of the block diagram are the sensor which is used to measure the vibrations. The sensor we are using in this project is MMA8451Q accelerometer, which is able to measure the vibrations. The vibration data need to be measured from the acceleration data of the accelerometer by setting different thresholds. Then the data from the accelerometer need to be transferred to the microcontroller which is used to process the data. The microcontroller which we have selected to do the processing of the data is MKL25Z32VFM4 which is ARM® Cortex™-M0+ processor. This is best suited for the processing of the accelerometer data. There are different types of protocols that can be used to communicate with this controller. It supports SPI, I2C etc, the communication between the accelerometer and the microcontroller uses I2C protocol to transfer the data between two. For development we used MKL25Z128VLK4 controller. Even this is also ARM® Cortex™-M0+ processor. The reason for using this processor is this processor will be available on a FRDM KL25Z board from freescale and this board also has MMA8451Q accelerometer populated on the board. So till the completion of designing the PCB this board can be used for development. The processor which will be used in the final product and the processor which we are using now for development...

...Tobi Gonzalez 2/25/13 Motion is Relative 1. The two units of measurement are distance and time. 2. The kind of speed is registered by an automobile speedometer is instantaneous speed. 3. Average speed is the speed averaged over duration of time. Usually the total distance covered divided by the total time. Instantaneous speed is the speed given at that instant within that span of time, measured with a real time speedometer. 4. The average speed in kilometers per hour for a horse that gallops a distance of 15 km in a time of 30 min is: Average speed = 15 km/30 min = 15 km/0.5 h = 30 km/h 5. Speed is the distance covered per unit of time. Acceleration is the rate in which an object changes its velocity. 6. If a car is moving at 90 km/h and it rounds a corner, also at 90 km/h, it does maintain a constant speed but not a constant velocity. The velocity never changed, only the direction it’s traveling. 7. Velocity is change in displacement, change in position over a period of time, while Acceleration is change in velocity over a time period. 8. The acceleration of a car that increases its velocity from 0, to 100 km/h in 10s is 10km/h*s 9. The acceleration of a car that maintains a constant velocity of 100 km/h for 10s is 0 km/h*s. Some of my classmates get this question wrong but the last question right because they fail to read the question. In the last question there was a change in velocity. However in this question there was no change in...
