Bill Miller and Value Trust Free Essays

string(81) " that could be acquired through a close analysis of the company and the economy\." ? Bill Miller and Value Trust Background Information Bill Miller is one of the most renowned professional fund managers. This can be proven by the outperformance of the Value Trust, which is managed by him, compared to its benchmark index, the Standard Poor’s 500 Index (SP 500), for an astonishing 14 years in a row; and this marked the longest streak of success for any manager in the mutual-fund industry. By the middle of 2005, Value Trust is worth $11. We will write a custom essay sample on Bill Miller and Value Trust or any similar topic only for you Order Now 2-billion. Bill Miller’s approach to investment management was research-intensive and highly concentrated. For instance, nearly 50 percent of Value Trust’s assets were invested in just 10 large-capitalization companies. While most of Bill Miller’s investments were value stocks, he was not averse to taking large positions in the stocks of growth companies. In other words, Bill Miller’s investing style is iconoclastic: â€Å"You simply can’t do what he’s done in the supremely competitive, ultra-efficient world of stock picking by following the pack†¦The fact is that Miller has spent decades studying freethinking overachievers, and along the way he’s become one himself. † Mutual Funds Definition A mutual fund is an investment vehicle that pooled the funds of individual investors to buy a portfolio of securities, stocks, bonds, and money-market instruments to meet specific investment objectives; investors owned a pro rata share of the overall investment portfolio (Bruner, 2007). The various investments included in a fund’s portfolio are handled by professional money managers in line with the stated investment policy of the fund. All mutual funds have a portfolio manager, or investment advisor, who directs the fund’s investments according to explicit investment objectives. Mutual Fund Types Investors have different objectives, so various types of mutual funds are needed to help them achieve their goals. Most mutual funds fit into one of three basic categories: money market mutual funds, bond funds, and stock funds. Money market mutual funds hold cash reserves, or short-term debt investments issued by the government, corporations, or financial institutions (i. e. , U. S. Treasury bills and bank certificates of deposit). Bond funds invest in debt instruments issued by corporations or government agencies. Stock funds are one of the most popular types of mutual funds, ranging from relatively conservative equity income funds to value funds, growth funds, aggressive growth funds, small-company funds, and international funds (Hirschey and Nofsinger, 2008). Advantages of Mutual Funds Diversification Using mutual funds can help an investor diversify their portfolio with a minimum investment. When investing in a single mutual fund, an investor is actually investing in numerous securities and spreading investment across a range of securities can help to reduce risk but will never completely eliminate it. If a few securities in the mutual fund lose value or become worthless, the loss maybe offset by other securities that appreciate in value. Professional Management Mutual funds are managed and supervised by investment professionals. As per the stated objectives set forth in the prospectus, along with prevailing market conditions and other factors, the mutual fund manager will decide when to buy or sell securities. This eliminates the investor of the difficult task of trying to time the market. Furthermore, mutual funds can eliminate the cost an investor would incur when proper due diligence is given to researching securities. Convenience With most mutual funds, buying and selling shares, changing distribution options, and obtaining information can be accomplished conveniently by telephone, by mail, or online. Minimum Initial Investment Most mutual funds have a minimum initial purchase of $2,500 but some are as low as $1,000. Disadvantages of Mutual Funds Risks and Costs Changing market conditions can create fluctuations in the value of a mutual fund investment. There are fees and expenses associated with investing in mutual funds that do not usually occur when purchasing individual securities directly. There are drawbacks associated with mutual funds: No Guarantees. The value of mutual fund investment could fall and be worth less than the principle initially invested. The Diversification â€Å"Penalty†. Diversification can help to reduce your risk of loss from holding a single security, but it limits your potential for a â€Å"home run† if a single security increases dramatically in value. Costs. In some cases, the efficiencies of fund ownership are offset by a combination of sales commissions, redemption fees, and operating expenses. If the fund is purchased in a taxable account, taxes may have to be paid on capital gains. Expenses Because mutual funds are professionally managed investments, there are management fees and operating expenses associated with investing in a fund, which is called expense ratios ranging from 0. 2% to 2. 0%. These fees and expenses charged by the fund are passed onto shareholders and deducted from the fund’s return. Taxes As a fund shareholder, you can be taxed on distributions of dividends and/or capital gains made by the fund and profits you make when you sell the fund shares. Research Hypothesis 1. There is a possibility that his overall performance may be affected because of Bill Miller’s choice of concentrating heavily in certain sectors such as financials, health, consumer goods, and telecommunications. 2. By examining and analyzing various theoretical explanations, we will be able to determine whether Bill Miller’s success is dependent on luck and/or skill and whether it is sustainable or not. Evaluation of Bill Miller’s Performance Bill Miller’s results seemed to contradict conventional theories, which suggested that, in markets characterized by high competition, easy entry, and information efficiency, it would be extremely difficult to beat the market on sustained basis. Efficient Market Hypothesis (EMH) There are three levels of market efficiency which were distinguished by the degree of information believed to be reflected in current securities’ prices. The weak form of efficiency maintained that all past prices for a tock were impounded into today’s price. The semistrong form of efficiency held that today’s prices reflected not only all past prices, but also all publicly available information. The strong form of efficiency held that today’s stock price reflected all the information that could be acquired through a close analysis of the company and the economy. You read "Bill Miller and Value Trust" in category "Papers" Many sc holars argued that the sock market followed a â€Å"random walk†, where the price movements of tomorrow were essentially uncorrelated with the price movements of today. They argued that capital markets’ information was efficient, and that the insights available to any one fundamental analyst were bound to be impounded quickly into share prices. If EMH were correct and all current prices reflected the true value of the underlying securities, then arguably it would be impossible to beat the market with superior skill or intellect. â€Å"In such a market,† as one economist said, â€Å"We would observe lucky and unlucky investors, but we wouldn’t find any superior investment managers who can consistently beat the market. Yet, Bill Miller, who over long periods, greatly outperformed the market. In reply, Malkiel suggested that beating the market was much like participating in a coin-tossing contest where those who consistently flip heads are the winners. Malkiel suggested that the success of a few superstar portfolio managers could be explained as luck. Similarly, the stock-market crash on October 1987 had also seemed to undermine t he strength of the EMH. Academic research exposed other inconsistencies with the EMH, for example, January effect, blue Monday effect, etc. Those results were inconsistent with a random walk of prices and returns. Bill Miller was an adherent of fundamental analysis; his approach was research-intensive and highly concentrated. Nearly 50% of Value Trust’s asserts were invested in just 10 large-capitalization companies. Analysis of Bill Miller’s Key Strategies Bill Miller, portfolio manager for Legg Mason Value Trust, had a great track record for an astonishing fourteen years in a row. He was the only active mutual fund manager to have consistently beaten the SP 500 over the last fourteen years. Bill Miller pointed out that his streak was due to luck; 95 percent luck. This section will evaluate Bill Miller’s investment philosophies and whether he is just plain lucky or it is based on luck and sustainability. The figure below lists the categories in which Bill Miller has invested in and the annual returns each category receives: As can be seen in the figure above, Value Trust has a portfolio that is highly volatile. Although highly volatile, the concentrated portfolio still showed outperformance when judged by calendar years, thus giving an ominous sign that the outperformance is not the result of good stock picking, but merely the result of taking on greater risk than the market as a whole. Bill Miller’s investment philosophy to build up Value Trust is to consistently buy cheap stocks, and focused on established companies suffering through periods of poor performance. These judgments resulted in Value Trust’s outperformance for fourteen years. However, taking risks (i. . having a highly concentrated volatile portfolio) and underperforming the value style (i. e. buying cheap stocks from companies suffering through periods of poor performance) is not a good combination and could hurt him later on. One might think that Bill Miller’s investment philosophy could be a â€Å"value trap†, mistaking a more or less permanent change in value or industry conditions for a tempora ry one. The bulk of Bill Miller’s portfolio is from consumer (i. e. homebuilding) and financial categories. These stocks tend to trade at cheap prices. Furthermore, the housing bubble began inflating in mid 1990’s, thus making it an easy way for investors like Bill Miller to make money. This event led to further success of Value Trust despite the high level of volatility. Investment Philosophies Buy low-price, high intrinsic-value stocks Bill Miller tends to invest in stocks that are undervalued by the market. People believe that a business is broken, scandal, but the company is still able to generate positive future cash flows. He buys low and sell high. The market price in long run still imitates the value of the firm. Take heart in pessimistic markets Bill Miller tends to invest in stocks that have the least promising outlook and sell those stocks that have the greatest opportunity for near-term gain. In other words, Bill Miller is investing in stocks that have the greatest opportunity for long-term gain instead of near-term gain. Remember that the lowest average cost wins The lower the shares go, the higher the future rate of return and the more money you should invest in them. When a stock drops and he believes in the fundamentals, the case for future retunes goes up. Again, market price in long run still imitates the value of the firm. Buy low-expectation stocks When the market’s been down for a while, and it looks bad, then you should be more aggressive, and when it’s been up for a while, then you should be less aggressive. Bill Miller thinks buying low-expectation stocks, buying higher dividend-yielding stocks, staying away from things with high expense ratios. Take the long view Bill Miller tends to hold onto stocks he invested in for a long period of time which results in a low portfolio turnover. According to him, the biggest opportunity for investors is really thinking out longer term. Look for cyclical and secular underpricing Bill Miller tends to invest in stocks that are undervalued or mispriced. He believes that most growth people own stocks that are secularly underpriced; things that can grow for long periods of time. Behavioural Finance Bill Miller’s educational background in Philosophy and Economics and his active involvement in the study of Behavioural Finance reflect his investment strategy. During Bill Miller’s Investment Conference in 2004, he remarked that â€Å"I believe that every exploitable anomaly in the market is behaviourally based. This is the only way that sustainable anomalies can be created. These are the anomalies that are not easily arbitraged away. One of the most remarkable behavioural anomalies that we see is that people take today’s data (e. g. , the GDP report, the unemployment report) and concludes that the market is getting ahead of itself. The market does not look at today’s data. It is looking at the data down the road. † This statement demonstrates that his belief that the market reflects the available information fairly accurately in the short term. In addition, he remarked that â€Å"Because the market looks forward, because the market discounts, and because the market prices reflect, in essence, the data refracted through the decision procedures and emotions of investors, then the market will change as the world changes because it is incorporating new information. † With this statement, it appears that Bill Miller expresses a partial belief in the EMH, unlike Warren Buffet. Value Investing As what was stated in the case, Bill Miller has been following an approach to equity investing and followed a number of strategies, specifically Ben Graham’s. Bill Miller analyzes and evaluates the stocks performance in the long run which explains his strategy of buying low, with high intrinsic value. In addition, he has been holding onto stocks for a longer period than an average fund manager, hence a low turn-over rate which explains his strategy of taking the long view. Conclusion By comparing Miller’s investment philosophy with Warren Buffett’s, there is one thing that makes Buffett’s investment philosophy more applicable and Miller’s philosophy a â€Å"swing-for-the-fences† approach. Miller should look at a company’s financials before making an investment. His view of welcoming negative sentiment about companies and buying stocks as their prices fall failed to look at the company’s liquidity. The company could have issues with high levels of debt and poor financials. Even though if for instance, some of his stocks (due to volatility) have failed to meet his expectations (a â€Å"stinker†), the inflated housing bubble that grew during the 1990s caused high levels of annual return could still make the overall performance of Value Trust successful compared to the others. Thus, given the nature of his concentrated portfolio, his long outperformance can be seen as a random variable, or â€Å"luck†. There are approximately 8,044 mutual funds out there; and 4,600 of these were U. S. equity mutual funds. Thus, there is a 50 percent chance of beating the market. Since Bill Miller has outperformed its competitors over fourteen consecutive years, how come no one has followed in his footsteps? How to cite Bill Miller and Value Trust, Papers

Occupational Health Management in Hospitality Industry

Question: Discuss about the Occupational Health Management in Hospitality Industry. Answer: Introduction: The occupational health and safety refers to the multidisciplinary ground that is concerned with health, safety and the welfare of people in workplace. This helps the employees to reduce the accidents, injuries and medical illness in the workplace (Hammer, Truxillo, Bodner, Rineer, Pytlovany, Richman, 2015). Health and safety programs can be arranged to reduce the problems regarding health and safety in the workplace of hospitality management. This may include the controlling of hazards and development of safety plan, inspection of workplace, training of the employees, investigation of the incidents. The main aim of the assignment is to make people aware about the health and safety in the workplace. This paper provides clear overview of emerging occupational health safety issues for the workers of hospitality industry. The paper focuses on the manifestation of health hazards risks and their prevention. The paper discusses about the legislative requirements of occupational health and safety and the standard industry practice. According to Ariza-Montes, Arjona-Fuentes, Law, and Han (2017), there are various hazards that are found in the workplace and millions of workers die annually. In hospitality industry, overexertion is common for the workers to move fixtures and furniture. This can be prevented by the bending the knees and balancing the body. The employees need to know the smooth and gradual motions. Moatari-Kazerouni, Chinniah, and Agard (2015) mentioned that another health and safety issue in the hospitality industry is the burning. Approximately 14 % of accidents are happened due to spill or splash of hot surface or hot liquids. Unguarded machineries may cause serious cuts, fractures, amputation and crushing injuries. Moatari-Kazerouni and Chinniah (2015) argued that the mentioned two hazards can be preventive if the workers know the proper technique. Therefore, the workers need proper training for the self-protection. Moreover, the authority should have the hazard prevention arrangements for the w orkers. The items need to be dried before using those items with the hot oil. The workers need to make sure that they handle pots and the pans, which do not move out from the stoves. They can use the dry clothes during handling the hot objects. Zhang, Kandampully, and Choi (2014) mentioned that to reduce the injuries from the unguarded machinery, the workers need to check if all guards are in place before using. The workers need to check the instructions of the manufactures before the equipments for the safety purpose. () argued that the old equipments should be replaced by the new guarded equipments. Slippery floor is another risk of the occupational health and safety hazards. The workers may slip and therefore, it may cause fracture, breakdown of hip or leg bone. The workers can use the non-slip foot wares and keep the floor clean and water free. Grawitch, Ballard, and Erb (2015) suggested that rubber mat can be used on the floor to avoid the hazards due to slippery floor. The workers in the hospitality industry have to work with the knives and sharp equipments. They need to know the usage of the sharp equipments to avoid the cut and injuries that may cause by using the sharp knives. To avoid the problems by using the sha rp knives, the workers can use cutting board. They need training so that they can use the right knife for the particular jobs. They need to be aware during using the knives such as cutting vegetables, washing sharp equipments (Model Work Health and Safety Act - Safe Work Australia., 2012). The workers can use the personal protective equipments like chemical resistant gloves, work gloves, disposable waterproof glove, non-slippery foot wares, and safety glasses and face shield (Tompa, et al., 2016). The chemical resistant gloves can be used during handling and cleaning the chemicals. The workers can use the hand gloves during garbage handling, working in the storage areas and doing landscaping. The disposable waterproof gloves are used to clean blood and body fluids. To handle the cuts and cleaning the operational equipments, the workers can use the cut- resistance gloves. The non- slippery foot wares can be used during working in the kitchen and they can use the steel boots during operating the landscaping equipments. The safety glasses are used for the eye protection during cooking or handling hazardous equipments. The hazardous chemicals may splash on face therefore; the workers need to use the safety face shields and safety goggles. Another type of hazards is the bio hazards that are cleaning the bathrooms, laundry or kitchen. To prevent such hazards, Benavides-Velasco, Quintana-Garca, and Marchante-Lara (2014) suggested that the workers need to use the personal protective equipments. They can use the waterproof bags to collect the garbage of bathroom, kitchen and laundry. They need to hold the plastic garbage-collecting bag far from their body. They can use masks during cleaning the bathroom, kitchen. In view of Rahman, Palaneeswaran, Kulkarni, and Zou (2015), workplace violence is another reason of the occupational health and safety hazards. The workers should have the ability to understand the early signs of violence and prevent them on the early stage to decrease the chance of hazards. They need to have the ability to handle problems and help the customers as quickly as possible. They need to develop the communication skill and know about the health and safety policies and legislation. Sometimes, the workers may face problems outside the workplace. For example, during coming to the workplace, accidents may happen on the roads. The workers need to be careful and have the ability of handling problems via strong communication skills. The workers need to assess the problems first and should have proper training to handle the risk factors (Jones, Jones, Hillier, Hillier, Comfort, Comfort, 2016). It is the responsibility of the authority to arrange training sessions for the workers and reduce the risks of the health and safety hazards in workplace. Another problem of the hospitality industry workers may be the improper reservation of the employee and customer data. They need to follow the Data Protection Act to avoid the conflict with customers. This will help to reduce the violence in the workplace. The Work Healthy and Safety Act (2011) provide the structure for protecting the welfare, health and safety of the workers at the workplace. It helps to protect the health and safety of everyone working in the workplace including the employees, subcontractors, contractors, outworkers, apprentices and trainees, volunteers and employers. However, the work health and safety act tries to protect the public, who may be affected by the workplace hazards (Schubauer-Berigan, Dahm, Schulte, Hodson, Geraci, 2015). The work health and safety act sets out the needs of following: The notification of incidents Workers with consultation Resolution of issues The functions and inspector power Penalties and offences From the information sheet of the Australian and other Standards provides common guidance to the duty holders on the Australian and other Standards. This will guide the workers to interact with the model of Work Health and Safety Act and the Work Health and Safety Regulations. This may cover the definition of Standard; conform of Standard, WHS laws with the codes of practice. The model of Work Health and Safety Act structures the basis of work health and Safety act. It has been applied in the most jurisdictions in Australia. However, () mentioned that the Parliament of the jurisdiction needs to pass the work healthy and safety act to have the efficient and effective jurisdiction. This model will help the workers to maintain the healthy and wellbeing lifestyle. There are some standard industry practice of health and safety. The workers need to obey the code of practice. The standard industry practice of health and safety helps to define the safety and health needs and precautions, which is applicable to the government, employers, manufactures and the employees (Work Health and Safety Act 2011, 2012). This standard industry practice focuses on prevention of the workplace violence and the adverse consequence. The code intend to serve the basic reference tools to stimulate improvement of equipments in regional, sectoral, national, organizational and workplace level. This code helps the guide the employers for adapting the positive strategies to manage the disability related problems in workplace. Based on the above discussion, it can be concluded that the occupational health and safety plays important role in the development of the hospitality industry. To reduce the problems regarding health and safety in the workplace of hospitality management, the worker need to know various thing. For example, they need to know the controlling of hazards and development of safety plan, inspection of workplace, training of the employees, investigation of the incidents. The Work Health and Safety Act (2011) plays important role to teach the workers about the safe process to work in the workplace. They can use the personal prevention equipments for the self protection and avoid the health hazards. The Work Health and Safety legislation model can help the workers to maintain the healthy and wellbeing lifestyle. The standard industry practice of health and safety helps to define the safety and health needs and precautions. References Ariza-Montes, A., Arjona-Fuentes, J. M., Law, R., Han, H. (2017).

Projectile range and projectile motion Essay Example

Projectile range and projectile motion Paper As we all know ski jumping is a worldwide sport in which athletes skate down a slope ramp, gaining speed that throws them in the air that makes them land some distance away. The distance travelled at the time when the jumper leaves the ramp, until he reaches the ground is known as the jump range. This interesting and challenging sport involves a lot of physics behind it. Kinetic energy, gravitational potential energy, motion, speed, height, time, distance and the athletes ability to reduce air resistance to their body are all factors that determine the athletes performance. This experiment represents a ski jumping slope through which we will investigate and demonstrate how physics can be used by ski jumpers to increase their range in the jump. Aim: My aim of this experiment is to explore the relationship between the launch height and the range of the jump. I will use the my knowledge of physics knowing that gravitational potential energy can be converted into kinetic energy and using the equations ? Egrav = mg? h for gravitational potential energy and Ek = 1/2 mv2 for the kinetic energy to work out the relationship between height, velocity and the range of the projectile. We will write a custom essay sample on Projectile range and projectile motion specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Projectile range and projectile motion specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Projectile range and projectile motion specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Hypothesis I predict that the higher ramp, the higher the velocity therefore an increase in range. Null Hypothesis There will be no relationship found between the height of the ramp, velocity and the range of the projectile. Rationale The displacement, velocity and acceleration of the projectile are all vectors. The forces of the projectile motion can be treated separately, so they can be resolved into horizontal and vertical components. They are independent of each other; that is, neither motion affects the other. We can label these components x and y. The horizontal component can be represented as Vx and the vertical component as Vy. Vx = V cos ? Vy = V sin ? The projectile/ball baring will be dropped from the top of the ramp giving the projectile gravitational potential energy. We can work out the gravitational potential energy by using ? Egrav = mg? h as we know the mass of the projectile, gravitational effect and the height at which the projectile is launched. As the projectile travels down the ramp it will be affected by air resistance and friction, however in this experiment we will ignore these factors. The point at which the projectile starts moving down the ramp, the gravitational potential energy converts into kinetic energy allowing it to accelerate off the ramp and into the air. We can use the equation Ek = 1/2 mv2 to work out the kinetic energy. Ignoring air resistance and friction, we know that the gravitational potential energy at the top of the ramp will equal the kinetic energy when it leaves at the bottom. This experiment involves me looking at the relationship between the height and the range of the projectile. In theory by changing the height I am changing the velocity of the projectile and so therefore the range will be affected. By re-arranging the equation Ek = 1/2 mv2 we can work out the velocity of the ball baring, 2Ek/m = v2 then do V v2 = v. This can also be simplified to give V (2mgh) /m = v. The m cancels which will leave us with V = V (2gh). We can then use the equation V = Distance/Time which will give the theoretical horizontal value. We can re-arrange this equation to give us the distance, Distance = Velocity x Time. This is the horizontal component. Changing the vertical height of the drop from the ramp would vary the range. This is because according to the law of energy, it cannot be made or destroyed but transferred. To apply this law into this practical, we can say all of the gravitational potential energy is converted into kinetic energy assuming no energy is wasted. As a result, gravitational portential energy is equal to kinetic energy.
