Relevance of Portfolio Theory and Capital Asset Pricing Model Essay

Relevance of Portfolio Theory and Capital Asset Pricing Model - Essay Example In fact risk taking is directly linked to larger amount of earnings. In order to lure investors, risky investments must offer greater returns. Actually risk and returns go hand in hand. It is the belief of investors to distribute their risks and so they diversify their investments as well. They always like to make their investments in a portfolio of assets as they never like to stack all their eggs in one basket. Hence what really matters is not the risk and returns alone, but the risk and return on a portfolio of assets on the whole. According to James Bradfield (2007, p167) an assortment of securities is known as a portfolio. Portfolio theory is a conventional scrutiny of the relationship between risk and return on the risky securities. The rate of returns is particularly measured through alpha, beta, and R-squared. A random variant denotes the rate of return from a portfolio. The computation of the probability distribution generating the returns rate of the security contained in the portfolio depends on the probability distribution creating the value for the portfolio. The hypothesis is helpful for a patron. It helps them to decide and allocate their funds in risky securities thus creating a portfolio. This investment indicates the preferences with regard to the combination of risk and anticipated returns of the investors. The CAPM is a link between the risks and returns on the investments. After (Sharpe, William F.1964, pp. 425-442) developed the CAPM theory several other researchers have developed the theory with giving importance to the diversifiable and non-diversifiable risks of different investments. Previously the CAPM had only a single risk factor which was the risk of the entire movement of the market. This risk is denoted as "market risk" and the formula for CAPM is as follows: E (Ri) = Rf +i [E (RM) - Rf] Where E (RM) = expected return on a "market portfolio" i = measure of methodical risk of asset i comparative to "market portfolio". "The expected return for an asset i according to CAPM is equal risk free rate plus a risk premium" (Frank J. Fabozzi and Harry Markowitz, 2002, p.67). Later on research was conducted and the creators of CAPM theory related diversifiable which are unsystematic risks and non-diversifiable which are systematic risks for all the securities in the portfolio. Some management individuals conceived that CAPM is not genuine as it dominates participating management and investment study. Frank J. Fabozzi and Harry Markowitz states "even though the idea is not true it does not mean that the constructs introduced by the theory are not important. Constructs introduc

Heat Transfer from Steam to Water Lab Report Example | Topics and Well Written Essays - 3000 words - 1

Heat Transfer from Steam to Water - Lab Report Example Heat is a form of energy and the level of energy contained in a certain object is shown by the level of temperature in the object. The main purpose of this experiment was to test on the heat transfer from steam to water. Stem is usually produced when the water is heated to its boiling point and the heat can also be transferred from steam to water. Unlike the heat transfer by the other processes, e.g. condensation, radiation and conduction, heat transfer by condensation for example in steam does not involve temperature change. The steam passes on its latent heat to the products when it condenses on the heat transfer surface. This product formed for the condensate still contains its own sensible heat and this heat is of the same temperature that is contained in the steam from which it was produced. This experiment uses two sets of equipment. The first set is described under â€Å"Heating Liquids in Tank Storage.† The second set is described under â€Å"Corning Heat Exchanger.â €  The main aim of this experiment is to test on the heat transfer from the steam to water and to produce analysis from the data collected in the lab. Usually, the latent heat that is contained within the steam is released instantly as the steam condenses into the liquid state. The amount of latent heat that is released ranges from 2-5 times greater than the amount of sensible heat available from water after cooling.The objective is to determine the overall heat transfer coefficient (Uo) for the external heat exchanger at two different water circulation rates.   The rate of heat transfer that is often obtained during the condensation of the vapour is always very crucial since it is used in many industries in the steam heated vessels where the steam condenses and produces the heat. It is also applied in the distillation and evaporation where vapors produced must first be condensed. The latent heat of vaporization is produced at a constant temperature that is the boiling temperat ure of the liquid. The Equations were used to compute the over-heat transfer coefficient. The equations enabled the valves of both experimental as well as heat transfer coefficient to be calculated.

Types of informal research method Essay Example for Free

Types of informal research method Essay o What type of informal research method did you use? o How was your research method similar to research methods used by psychologists? o If given another opportunity, what would you have done differently? When thinking about a time I had to test a theory there are many that come to mind. One thing that comes to mind is when my middle daughter had a situation at school where she was being labeled with ADHD and the school demanded her to be put on medication. I wanted to make sure that if there was any issue then we could start at step one. I wanted to make sure that it was not something that was causing this or if it was something medically wrong. My theory was my daughter was bored and just acting out because she was not being challenged. Once I was given the information by the school to get my daughter on medication I used the information and looked online to find out if my daughter had any of the symptoms that the scyhool had described. I used Google to find out the information I needed and was directed to WebMD. I found out that many of the symptoms the school had described were not any of the symptoms I had seen in my daughter myself. I also contacted several groups and asked many questions. One of the most helpful was being able to contact not only my daughters’ pediatrician but I was able to contact several other doctors with informal questions. I also kept a log of my daughters’ behavior for a few weeks as well as have a few conversations with my daughter. It was almost like a process of elimination with changing diets, changing sleeping patterns and changing the home routine for a little bit. With her pediatricians advice I was also asked to do some of the things I had already done to see if that would make a difference. In the end it was just the school not being a good fit for my daughter and she was not being challenged properly while in school and once we relocated her to another school it seemed things slowed down and straightened out. If given another chance to help my children out properly or myself in a situation like this I would definitely do it again. I think  that we give in to the world of medication these days and rely too much on a magic pill to fix everything instead of going through the process of elimination to find out what is wrong with our daily lives and making sure what we do makes us really happy. How did the world function 20 years ago before the magic pills we are prescribed today? It is something to think about.

Coca Cola uses SWOT analysis to access their performance

Coca Cola uses SWOT analysis to access their performance Strengths Coca Cola is an enormously familiar company. Recognition is one of its bigger strengths that are almost unparalleled. Coca Cola is known very well across the world. Its branding is clear and renowned. The logo of Coca Cola is one of the most famous things in the world. Some people buy coke, not only because of its taste but because it is widely accepted and they feel like they are part of something so big and unifying. Overwhelming is the best word to describe Coca Colas popularity. It is scary to think that its popularity has been constantly growing over the years and the possibility that there is still room to grow. If you speak the words Coca Cola, it would definitely be recognized all around the world. Money is another thing that is strength of the company. Coca Cola deals with massive amounts of money all year. Like all businesses, they have had their ups and downs financially, but they have done well in this compartment and will continue to do well and improve. The money they a re earning is substantially better than most beverage companies, and with that money, they put back into their own company so that they can improve. Another strength that is very important to Coca Cola is customer loyalty. The 80/20 rule comes into effect in this situation. Eighty percent of their profit comes from 20% of their loyal customers. Many people/families are extremely loyal to Coca Cola. It would not be rare to constantly find bottles and cases of a product such as coke in a house. It seems that some people would drink coke religiously like some people would drink water and milk. This is an improbable feat. Weaknesses Coca Cola is a very successful company, with limited weaknesses. However they do have a variety of weaknesses that need to be addressed if they want to rise to the next level. Word of mouth is probably a strength and weakness of every company. While many people have good things to say, there are many individuals who are against Coca Cola as a company, and the products in which they produce. While people will have their opinions, you have to try to sway their negative views. If bad comments and views are put out to people who have yet to try Coca Cola products, then that could produce a lost customer which shows why word of mouth is a weakness. Another aspect that could be viewed as a weakness is the lack of popularity of many of Coca Colas drinks. Many drinks that they produce are extremely popular such as Coke and Sprite but this company has approximately 400 different drink types. Most are unknown and rarely seen for available purchase. These drinks do not probably taste bad, but a re rather a result of low profile or nonexistent advertising. This is a weakness that needs to be looked at when analyzing their company. Another weakness that has been greatly publicized is the health issues that surround some of their products. It is known that a popular product like coke is not very beneficial to your body and your health. With todays constant shift to health products, some products could possibly loose customers. Opportunities Coca Cola has a few opportunities in its business. It has many successful brands that it should continue to exploit and pursue. Coca Cola also has the opportunity to advertise its less popular products. With a large income it has the available money to put some of these other beverages on the market. This could be very beneficial to the company if they could start selling these other products to the same extent that they do with their main products. Another opportunity that we have seen being put to use before is the ability for Coca Cola to buy out their competition. This opportunity rarely presents itself in the world of business. However, with Coca Colas power and success, such a task is not impossible. Coca Cola has bought out a countless number of drink brands. An easy way to turn their profit into your profit is too buy out their company. Brand recognition is the significant factor affecting Cokes competitive position. Coca Cola is known well throughout 90% of the world populat ion today. Now Coca Cola wants to get there brand name known even better and possibly get closer and closer to 100%. It is an opportunity that most companies will ever dream of, and would be a supreme accomplishment. Threats Despite the fact that Coca Cola dominates its market, it still has to deal with many threats. Even though Coca Cola and Pepsi control nearly 40% of the entire beverage market, the changing health-consciousness attitude of the market could have a serious effect on Coca Cola. This definitely needs to be viewed as a dominant threat. In todays world, people are constantly trying to change their eating and drinking habits. This could directly affect the sale of Coca Colas products. Another possible issue is the legal side of things. There are always issues with a company of such supreme wealth and popularity. Somebody is always trying to find fault with the best and take them down. Coca Cola has to be careful with lawsuits. Other threats are of course the competition. Coca Colas main competition being Pepsi, sells a very similar drink. Coca Cola needs to be careful that Pepsi does not grow to be a more successful drink. Other product such as juices, coffee, and milk are threats.

Elvis Aaron Presley was born on January 8th,,1935 in Tupelo, Mississippi. His parents, Vernon and Gladys were poor farmers who had strong religious backgrounds. They raised Elvis in Tupelo where he learned how to sing and developed his guitar playing skills. Elvis did not have many friends growing up as a kid. His best friend was his guitar, which he picked up at age 11. When Elvis turned 13, his parents moved him to Memphis, Tennessee, where he attended Humes High School until 1953. Music was not Elvis’s first job. During his teens he worked as an usher and a truck driver. Elvis was driving down the road in his truck one day when he saw a sign that said RECORD MUSIC-FOUR SONGS FOR TWO DOLLARS. Elvis decided that he should see where he could take this opportunity. He went into the studio and recorded two songs for his mother. Elvis enjoyed recording and singing and began to send his tapes to managers. One manager, Colonel Tom Parker, enjoyed the sound of Elvis’s voice and decided to take on the young singer. Elvis kept recording and recording and sending and sending until finally he recorded two hits, â€Å"That’s All Right Mama† and â€Å"Blue Moon of Kentucky.† A sensation was born.

Masculinity in Deliverance by James Dickey Essay -- Establishment of M

Masculinity in Deliverance by James Dickey The novel Deliverance by James Dickey portrays the essence of middle-aged men experiencing the mid-life crisis through which they must prove to themselves and more importantly every one else that they still possess the strength, bravery, intelligence, and charm believed to be society's ideal of "masculinity." Dickey's four main characters undertake a risky adventure to satisfy their egotistical complexes and prove to the world that they are still the strong young men their wives married. Each character represents a different stereotype of the middle-aged man, and therefore experiences a different type of psychological and physical journey than their peers. The character Drew Ballinger in Deliverance is a sales supervisor at a soft-drink company who is very devoted to his son and his job. Drew is the character who represents the middle-aged man's desire for talent and attention. Drew plays the guitar and his music is his true companion. Without having any talent, as he would be the first to tell you, Drew played mighty well, through sheer devotion.(Dickey, 11) For Drew the highlight of this trip is his duo with Lonnie, an uneducated banjo player. Drew obviously finds this the most exhilarating part of the adventure in that he is the center of attention and is playing very well with a talented young man. I had never heard him play so well, and I really began to listen deeply, moved as an unmusical person is moved when he sees that the music is meant†¦.I could not see Drew's face, but the back of his neck was sheer joy†¦I was glad for Drew's sake that we had come. Jus... ...ecame a possession to me, a personal, private possession, as nothing else in my life ever had. Now it ran nowhere but in my head, but there it ran as though immortally. I could feel it - I can feel it - on different places on my body. It pleases me in some curious way that the river does not exist, and that I have it. In me it still is, and will be until I die, green, rocky, deep, fast, slow and beautiful beyond reality†¦The river underlies†¦everything that I do. It is always finding a way to serve me†¦(Dickey, 275-6) Thus, Ed is the protagonist and hero of Deliverance. It is through this perilous voyage that Drew, Bobby, Lewis, and Ed undertake, that they prove their "masculinity," or lack there of, to themselves and to the society in which they live.
