Literature Review on Volatility
Literature Review on Volatility Literature Review What is Volatility? Volatility is defined as the spread of all likely outcomes of an uncertain variable (Poon, 2005). Statistically, it is often measured as the sample standard deviation (as seen below), but can also be measured by variance. Where rt = return on day t, and ÃŽà ¼ = average return over the T-day period. The common misconception is to equate volatility to risk. However, whilst volatility is related to risk, it is not the same. Risk represents an undesirable outcome, whilst volatility is a measure for uncertainty that could arise from a positive outcome. Furthermore, volatility as a measure for the spread of a distribution contains no information on the shape, this represents another reason for volatility being an imperfect measure for risk. The sole exception to this being a normal distribution or lognormal distribution where mean and standard deviation are appropriate statistics for the whole distribution (Poon, 2005). In dealing with volatility as a subject matter in financial markets, the focus is on the spread of asset returns. High volatility is generally undesirable as it indicates security values are unreliable and capital markets arent functioning efficiently (Poon, 2005; Figlewski, 1997). Financial market volatility has been the subject of much research and the number of studies continues to rise since Poon and Granger (2003)s original survey first identified 93 papers in the field. A whole host of drivers for volatility have been explored (including political events, macroeconomic factors and investors behavior) in an attempt to better capture volatility and decrease risk (Poon, 2005). This study will add to that list, hoping to contribute something novel to the field by scrutinizing the appropriateness of different volatility models for different country indexes. The Importance of Volatility Forecasting Investment strategies, Portfolio Optimization and Asset Valuation Volatility when taken as uncertainty transforms into an important component in a wide range of financial applications including Investment strategies for trading or hedging, Portfolio optimization and Asset price valuation. The Markowitz mean-variance portfolio theory (Markowitz, 1952), Capital Asset Pricing Model (Sharpe, 1964) and Sharpe ratio (Sharpe 1966) signify three cornerstones for optimal decision-making and measurement of performance, advocating a focus on the risk-return interrelationship with volatility taken as a risk proxy. With Investors and portfolio managers having limits as to the risk they can bear, accurate forecasts of the volatility of asset prices for long-term horizons is necessary to reliably assess investment risk. Such forecasts allow investors to be better informed and hold stocks for longer rather than constantly reallocating their portfolio in reaction to movements in prices; an often expensive exercise in general (Poon and Granger, 2003). In terms of st ock price valuation French, et al. (1987) analyse NYSE common stocks for the period of 1928-1984 and find expected market risk premium to be positively related to the predictable volatility of stock returns, which is further strengthened by the indirect relationship between stock market returns and the unexpected change in the volatility of stock returns. Derivatives pricing Volatility is a key element in Modern option pricing theory that enables estimation of the fair value of options and other derivative instruments. According to Poon and Granger (2003) the trading volume of derivative securities had quadrupled in the recent years leading up to their research and since then this growth has accelerated with the global derivatives market now estimated to be around $544 Trillion excluding credit default swaps and commodity contracts (BIS, 2017). As one of five input variables (including Stock Price, Strike price, time to maturity and risk-free interest rate), expected volatility over the options life in the Black-Scholes model theorized by Black and Scholes (1973) is crucially also the only variable that is not directly observable and must be forecast (Figlewski, 1997). Implied volatility and realized volatility can be computed by referencing observed market prices for options and historical data. Whilst the former is attractive for requiring little input data and delivering excellent results when analysed in some empirical studies compared to time series models utilizing just historical information, it is deficient by not having a firm statistical basis and different strike prices yielding different implied volatilities creating confusion over which implied volatility to use (Tse, 1991; Poon, 2005). Lengthening maturities of derivative instruments also weakens the assumption that volatility realized in the recent past can be used as a fairly reliable proxy for volatility in the near future. (Figlewski, 1997). With recent developments, derivatives written on volatility can now also be purchased whereby volatility represents the underlying asset, thus further necessitating volatility forecasting practices (Poon and Granger, 2003). Financial Risk Management Volatility forecasting plays a significant role in Financial Risk Management of the finance and banking industries. The practice aids in estimation of value-at-risk (VaR), a measure introduced by the Basel Committee in 1996 through an amendment to the Basel Accords (an international standard for minimum capital requirement among international banks to safeguard against various risks). Whilst many risks are examined within, volatility forecasting is most relevant for Market risk and VaR. However, calculating VaR is necessary only if banks choose to adopt its own internal proprietary model for calculating market risk related capital requirement. By choosing to do so, there is greater flexibility for banks in specifying model parameters but with an attached condition of regular backtesting of the internal model. Apart from banks, other financial institutions may also use VaR voluntarily for internal risk management purposes. (Poon and Granger 2003; Poon 2005) Christoffersen and Diebold (2000) do however contend the limits of relevance of Volatility Forecasting for Financial Risk Management, arguing that for reliable forecastablity much depends on whether the horizon of interest is of a short term or long-term nature (taken to be more than 10 or 20 days) with the practice deemed more relevant for the former than the latter due to the limitations in forecastability. Policymaking Financial market volatility can have wide-reaching consequences on economies. As an example, large recessions create ambiguity and hinder public confidence. To counter such negative impacts and disruptions, policy makers utilize market estimates of volatility as a means for identifying the vulnerability of financial markets, equipping them with more reliable and complete information with which to respond with appropriate policies. (Poon and Granger, 2003) The Federal Reserve of the United States is one such entity that incorporates volatility of various financial instruments into its monetary policy decision-making (Nasar, 1991). Bernanke and Gertler (2000) explore the degree to which implications of asset price volatility impact monetary policy decision-making. A side-by-side comparison of U.S. and Japanese monetary policy is the basis of the study. The researchers find that inflation-targeting is desirable, however, monetary policy decisions based on changes in asset prices should only be made to the extent that such changes help to forecast inflationary or deflationary pressures. Meanwhile, Bomfim (2003) investigates the relationship between monetary policy and stock market volatility from the other perspective. Interest rate policy decisions that carry an element of surprise appear to increase short run, stock market volatility significantly with positive surprises also having a greater effect than negative surprises. Empirical stylized facts of asset returns and volatility Any attempt to model volatility appropriately must be done with an understanding of the common, recurring set of properties identified from numerous empirical studies carried out across financial instruments, markets and time periods. Contrary to the event-based theory in which it is hypothesized different assets respond differently to different economic and political events, empirical studies show that different assets do in fact share some generalizable, qualitative statistical properties. Volatility models should thus seek to capture these features of asset returns and volatility so as to enhance the forecasting process; herein lays the challenge. (Cont, 2001; Bollerslev et al 1994) Presented are some of these stylized facts, along with their corresponding empirical studies that have contributed to the evolving literature aimed at improving volatility-forecasting practices and which this study will also look to capture. Return Distributions Stock Market returns are not normally distributed and it is therefore an unsuitable distribution for modeling returns according to Mandelbrot (1963) and Fama (1965). Returns are approximately symmetrical but can display negative skewness and significantly have leptokurtic features (excess kurtosis with heavier tails and taller, narrower peaks than found in a normal distribution) that see large moves occur with greater frequency than under normal distributions (Sinclair, 2013). Cont (2001) asserts that these large moves in the form of gains and losses are asymmetric by nature with the scale of downward movements in stock index values dwarfing upward movements. He further argues that the introduction of GARCH-type models to counter the effects of volatility clustering can reduce the heaviness of tails in the residual time series to some small extent. However, as GARCH models can at times struggle to fully incorporate heavy-tail features of returns, this has necessitated the use of alte rnative distributions such as the students t-distribution employed in Bollerslev (1987). Alberg et al (2008) employ a skewed version of this distribution to various models with the EGARCH model delivering the best performance in forecasting the volatility of Tel Aviv stock indices. Cont (2001) does however also highlight an important consideration with the notion of aggregational gaussianity that as one increases time scale (t) for calculation of returns, the distribution of returns seems more normally distributed in appearance. Leverage effect/Asymmetric volatility In most markets, volatility and returns are negatively correlated (Cont, 2001). First elucidated by Black (1976) and particularly prevalent for stock indices, Volatility will tend to increase when stock price declines. The justification for this is because a decline in equity stock price will increase a companys debt-to-equity ratio and consequently its risk and volatility (Figlewski and Wang, 2000; Engle and Patton, 2001). Importantly, this relationship is asymmetric, with negative returns having a more marked effect on volatility than positive returns as documented by Christie (1982) and Schwert, (1989). However they also argue that the leverage effect is not enough on its own to explain all of the change in volatility with Christie (1982) incorporating interest rate as another element that has a partial effect. Hence, whilst, ARCH (Engle, 1982) and GARCH (Bollerslev, 1986) models do well to account for volatility clustering and leptokurtosis, their symmetric distribution fails to account for the leverage effect. In response to this, various asymmetric modifications of GARCH have been developed, the most significant of these being Exponential GARCH (EGARCH; Nelson, 1991) and GJR (Glosten et al, 1993). Other models like GARCH-in-Mean have also endeavored to capture the leverage effect along with the risk premium effect, another concept that has been theorized to contribute to volatility asymmetry by studies such as Schwert (1989) (Engle and Patton, 2001). Volatility Distribution The distribution of volatility is taken to be approximately log-normal. Various studies such as Andersen et al (2001) have postulated this. More significantly than the actual distribution is the high positive skewness indicating volatility spends longer in lower states than higher states. (Sinclair, 2013) Volatility-Volume correlation All measures of volatility and trading volume are highly positively correlated (Cont, 2001). Lee and Rui (2002) show this relationship to be foundationally robust, however what is more complex is determining the causality between the two. Strong arguments can be made either way. As an example, Brooks (1998) utilizes linear and non-linear Granger causality tests and finds the relationship to be stronger from volatility to volume than the converse. He concludes by highlighting that for forecasting accuracy, predicting volume using volatility is more productive than forecasting stock index volume and using such forecasts in trading. According to Gallant et al (1992) this relationship is also closely linked with the leverage effect and incorporating lagged volume weakens the effect considerably. Non-Constant Volatility Volatility is not constant. The changing nature of volatility occurs in a particular manner; Merton (1980) was critical of researchers who failed to incorporate this feature in their models. Firstly volatility is mean reverting. Indeed LeBaron (1992) found a strong negative relationship between volatility and autocorrelation for stock indices in the United States. Secondly, Volatility clusters. This is a phenomenon first noted by Mandelbrot (1963) that allows a good estimation of future volatility based on current volatility. Other studies such as Chou (1988) have also empirically shown the existence of clustering. Mandelbrot (1963) wrote, large changes tend to be followed by large changes of either sign, and small changes tend to be followed by small changes. In other words, a turbulent day of trading usually comes after another turbulent trading day, whilst a calm period will usually be followed by another calm period. Importantly, the phenomenon is not exclusive to the underlying product and can be seen in stock indices, commodities and currencies. It also tends to be more pronounced in developed than emerging markets. (Taylor, 2008; Sinclair, 2013) Engle and Patton (2001) argue that volatility clustering indicates volatility goes through phases whereby periods of high volatility eventually give way to more normal volatility with the contrary also holding. Engles (1982) landmark paper incorporated these features of volatility persistence using his ARCH model, whereby time varying, non-constant volatility that persists in high or low states is taken account of.

Emerging Markets; Risks and Challenges
Trade among these countries has also grown by a staggering amount in recent years and their multinational companies are now competing with those from the developed economies. There remain, however, significant risks and challenges to investing in these countries. They are discussed here under these broad headings; Political, Economic, Legal and Socio cultural. They affect the different countries in deferent ways and sometimes Interact in deferent ways to produce deferent results. For example, political processes more often than not drive economic, legal and social policies of governments.China and India, two of the largest emerging markets operate very different political processes and therefore have two very different sets of political institutions. Chinese communism and Indian democracy vary significantly, and their political systems ultimately affect the choice of economic, legal and social policies. The first step to emerging market status for most of these countries can be trace d to political reforms and/or movements, examples being the transition from authoritarian to democratic governments and economic liberation's.It can also be argued that social reforms and/or popular movements brought about the downfall of the authoritarian governments in the first place, allowing for reforms in the political and economic systems In place (the political economy), thus paving the way for economic gains witnessed today. Despite the often complex interactions between these factors, wave attempted to simplify them by grouping them In broad categories. Emerging markets also face challenges as they come to grips with economic prosperity and their new status in the global community.

Salah: Spiritual Nourishment of the Soul
Salat: Salah Is ordained on Muslims five times a day and Is essentially the spiritual nourishment of the soul of the believer as well as the divine connection between Allah and the believer. There are 5 prayers throughout the day: Fajr (predawn), Dhuhr (afternoon), Asr (post-afternoon), Maghrib (evening), Isha (night). Salat In Qur'an: 1 . Establishing Salah Develops Taqwa (Fear and Awareness of Allah) : ââ¬Å"This Is the Book In which there is no doubt, a guidance for those who have taqwa; who believe In the unseen, and who establish Salah, and spend out of what we have provided for themâ⬠(2: 2-3) 2.Salah Is the Sign ofa Believer : ââ¬Å"The believers, men and women, are protecting friends of one another; they enJoln good and forbid evil, and they establish Salah, and give Zakah, and obey Allah and His Messenger.

Those Who Pray Shall Have Nothing to Fear on the Day of Judgment : ââ¬Å"Truly, those who believe and do righteous deeds, and perform Salah, and give Zakah, they will have their reward with their Lord. on them shall be no fear, nor shall they grieve. â⬠(2:277) 5. Remain in Allah's remembrance after prayer : ââ¬Å"When have finished performing the Salah, remember Allah standing, sitting, and eclining, but when you are free from danger, perform the Salah.Surely, Salah Is en]olned on the believers at fixed times. à ¢â¬ (4:103) 6. Command to Pray with Congregation : ââ¬Å"And establish Salah and give Zakah, and bow down (in worship) along with those who bow down (in worship)â⬠(2:43) 7. Special Command Regarding Punctuality of Prayer : ââ¬Å"Guara strlctly tne salan, especlally obedience. â⬠(2:238) 8. Allah's Help Comes Through Salah : e Saa .

Plant Bugs, Family Miridae
As their name suggests, most plant bugs feed on plants. Spend a few minutes examining any plant in your garden, and theres a good chance youll find a plant bug on it. The family Miridae is the largest family in the entire order Hemiptera. Description In a group as large as the family Miridae, there is a lot of variation. Plant bugs range in size from a tiny 1.5 mm to a respectable 15 mm long, for example. Most measure within the 4-10 mm range. They vary quite a bit in color, too, with some sporting dull camouflage and others wearing bright aposematic shades. Still, as members of the same family, plant bugs share some common morphological traits: four-segmented antennae, four-segmented labium, three-segmented tarsi (in most species), and a lack of ocelli. The wings are a key defining characteristic of the Miridae. Not all plant bugs have fully formed wings as adults, but those that do have two pairs of wings that lie flat across the back and overlap at rest. Plant bugs have a wedge-shaped section (called the cuneus) at the end of the thick, leathery part of the forewings. Classification Kingdom ââ¬â AnimaliaPhylum ââ¬â ArthropodaClass ââ¬â InsectaOrder ââ¬â HemipteraFamily ââ¬â Miridae Diet The majority of plant bugs feed on plants. Someà species specialize on eating a particular kind of plant, while others feed generally on a variety of host plants. Plant bugs tend to prefer eating the nitrogen-rich parts of the host plant ââ¬â the seeds, pollen, buds, or emerging new leaves ââ¬â rather than the vascular tissue. Some plant bugs prey on other plant-eating insects, and a few are scavengers. Predaceous plant bugs may specialize on a certain insect (a particular scale insect, for example). Life Cycle Like all true bugs, plant bugs undergo simple metamorphosis with just three life stages: egg, nymph, and adult. Mirid eggs are often white or cream-colored, and generally long and thin in shape. In most species, the female plant bug inserts the egg into the stem or leaf of the host plant (usually singly but sometimes in small clusters). The plant bug nymph looks similar to the adult, although it lacks functional wings and reproductive structures. Special Adaptations and Defenses Some plant bugs exhibit myrmecomorphy, a resemblance to ants that may help them avoid predation. In these groups, the Mirid has a notably rounded head, well distinguished from the narrow pronotum, and the forewings are constricted at the base to mimic an ants narrow waist. Range and Distribution The family Miridae already numbers well over 10,000 species worldwide, but thousands more may still be undescribed or undiscovered. Nearly 2,000 known species inhabit North America alone. Sources Borror and DeLongs Introduction to the Study of Insects,à 7th edition, by Charles A. Triplehorn and Norman F.

About the U.S. House of Representatives
The United States is a large, fractured, diverse and yet still unified nation, and few government bodies reflect the paradox that is this country better than the House of Representatives. Key Takeaways: U.S. House of Representatives The House of Representatives is the lower chamber of the two legislative bodies in the United States federal government.The House is currently made up of 435 representativesââ¬âreferred to as congressmen or congresswomenââ¬âwho serve an unlimited number of two-year terms. The number of representatives from each state is based on the stateââ¬â¢s population.As required by the Constitution, representatives must reside in the state from which they are elected, must have been a U.S. citizen for at least seven years, and be at least 25 years old.A representativeââ¬â¢s primary duties include introducing, debating, and voting on bills, proposing amendments to bills, and serving on committees.The House has the exclusive powers to initiate all tax and spending bills and to impeach federal officials.à Metrics of the House The House is the lower of the two legislative bodies in the U.S. government. It has 435 members, with the number of representatives per state dependent upon that states population. House members serve two-year terms. Rather than represent their entire state, as Senate members do, they represent a specific district. This tends to give House members a closer link to their constituents-and more accountability, since they have but two years to satisfy voters before having to run for re-election. Also referred to as a congressman or congresswoman, a representativeââ¬â¢s primary duties include introducing bills and resolutions, offering amendments and serving on committees.à Alaska, North Dakota, South Dakota, Montana and Wyoming, all sprawling but sparsely populated states, have just one representative each in the House; tiny states like Delaware and Vermont also send just one representative to the House. By contrast, California sends 53 representatives; Texas sends 32; New York sends 29, and Florida sends 25 representatives to Capitol Hill. The number of representatives each state is allotted is determined every 10 years in accordance with the federal census. Although the number has changed periodically through the years, the House has remained at 435 members since 1913, with shifts in representation occurring among different states. The system of House representation based on district population was part of the Great Compromise of the Constitutional Convention in 1787, which led to the Permanent Seat of Government Act establishing the nations federal capital in Washington, DC. The House assembled for the first time in New York in 1789, moved to Philadelphia in 1790 and then to Washington, DC, in 1800. The Powers of the House While the Senates more exclusive membership may make it seem the more powerful of the two chambers of Congress, the House is charged with a vital task: the power to raise revenue through taxes. The House of Representatives also has the power of impeachment, in which a sitting president, vice president or other civil officials such as judges may be removed for high crimes and misdemeanors, as enumerated in the Constitution. The House is solely responsible for calling for impeachment. Once it decides to do so, the Senate tries that official to determine whether he or she should be convicted, which means automatic removal from office. Leading the House House leadership rests with the speaker of the house, usually a senior member of the majority party. The speaker applies House rules and refers bills to specific House committees for review. The speaker is also third in line to the presidency, after the vice president. Other leadership positions include the majority and minority leaders who monitor legislative activity on the floor, and the majority and minority whips who ensure that House members vote according to their respective parties positions. Theà House Committee System The House is divided into committees in order to tackle the complex and various matters on which it legislates. House committees study bills and hold public hearings, gathering expert testimony and listening to voters. If a committee approves a bill, it then puts it before the entire House for debate. House committees have changed and evolved over time. Current committees include those on: agriculture;appropriations;armed services;the budget, education, and labor;energy and commerce;financial services;foreign affairs;homeland security;House administration;judiciary;natural resources;oversight and government reform;rules;science and technology;small business;standards of official conduct;transportation and infrastructure;veterans affairs; andways and means. In addition, House members may serve on joint committees with Senate members. The Raucous Chamber Given the shorter terms of House members, their relative proximity to their constituents and their larger numbers, the House is generally the more fractious and partisan of the two chambers. Its proceedings and deliberations, like those of the Senate, are recorded in the Congressional Record, ensuring transparency in the legislative process.

Air pollution Essay example - 520 Words
Air pollution You canââ¬â¢t escape from it. Everybody has to breath, and when air isnââ¬â¢t clean you health is affected. Air pollution is problem of all of us. You might think that you are healthy because you eat, and do only healthy things, so you cannot be sick, or get cancer, allergies or even die.

Lead has been phased out of gasoline, but there, are other sources of it. It includes paints, production of lead batteries, water pipes, and a few heir dye products. Car exhausts can also produce nitrogen oxide, volatile organic compounds, which are also, product of burning fuels. Factories and power plants produce same pollutants as cars do, but they produce them in bigger mnozstve and the produce some more such as sulfur dioxide, which is made during production of paper, burning coal in power plants, or smelting of metal. Burning other fuels like wood, or natural gas can make all of these pollutants too. The other problem closely related to industrialization is problem of big cities. The problem of air pollution increases in the bigger cities because mnozstvo of cars, buses, and trucks.

Marketing Management and Digital Communications
Question: Discuss about the Marketing Management and Digital Communications. Answer: Introduction: Samsung Electronics is a South Korean company that deals in mobile phones and the general electronics. The company produces most of the world's powerful phones which are used by many people from different parts of the world. The company has recently manufactured Samsung Leader 8 product. This is a Smartphone with dual screen flip and some classic keyboard. The phone has a rear camera of 12MP and a front camera of 5MP. Thus it is robust and fit enough to satisfy the customer's needs of camera needs. Samsung Leader 8 also has programmable hotkeys. Regarding its way of charging, the phone has a new feature of wireless charging unlike most of the phones in the market. Therefore, Samsung Leader 8 seems to be a perfect product to meet most the current market needs of smartphones. Successful marketing of every company's product relies on the effectiveness of the marketing plan. Marketing that has been implemented well must contain information that reveals that current marketing state of the organization and the possible strategies that can effectively reach the market. The plan has the aims and objectives of developing the market brand awareness for Samsung Leader 8 in Australia. This is important for the Samsung because it will help it attain a bigger market ratio in the country (Kaplan Norton, 2008). The plan also establishes the possible market opportunities and the threats for Samsung Leader 8. This has been achieved through the application of SWOT analysis which provides important market information to help the company succeed in the endeavor. The plan has set the marketing and financial objectives for Samsung Leader 8 which is an important aspect in directing and targeting in the course. Further, the plan establishes the various marketing mix strategies that likely improve the sales of Samsung Leader 8 in the market. Thus, the paper is critical to help Samsung attain many sales of Samsung L8 in the Australian market. In analyzing the internal business situation of Samsung, SWOT analysis seems to be a fit tool to unveil the current market opportunities, the threats, opportunities, and strengths. SWOT is powerful in helping the organization's management understand the environment (Lee Law, 2012). Thus, the organization's leaders will be in a good position to make the best decisions for the marketing of the product (Ghazinoory, Abdi and Azadegan-Mehr, 2011). In SWOT analysis, strengths refer to the aspects that lie within the business organization that can be helpful to the company and makes it stay above other market industry players (Kim, Hayes, Avant Reid, 2014). Samsung has many strengths internally that can be helpful to the sale of Samsung Leader 8. Firstly, Samsung is the most successful company in production of the phones and the general electronics in the world. The company has an already established brand name both in Australia and the rest of the world. This is a strength of this organization. Secondly, Samsung an already established market share. The company has a share of more than 21% of the world phone market thus, a strength aspect for the success of the company in marketing the Samsung Leader 8 in Australia. Besides, Samsung has an advantage of its heavy investment in the research and development. This is important and helps the company develop what is fit for the market (Koen, Bertels Elsum, 2011). There are various factors within Samsung environment that present challenges to its operation. Firstly, the Samsung Leader 8 seems weaker and not robust enough in the market compared to smartphones from other industry players. Some of this smartphone makers include Apple, which has stayed ahead of Samsung for quite an extended period. Thus, has never managed to match the bigger market share and robustness of Apple's smartphones. Other companies that compete Samsung include many Chinese companies, such as Huawei which offers smart phone alternatives in Australia. Also, Samsung Leader 8 depends on the Google Android which is an open source operating system for this phone, making it inferior to Apple's IOS Devices. Besides, the marketing strategies employed by Samsung are not as robust as those used by Apple (Yuece, 2012). Samsung Leader 8 has many opportunistic factors that that can be used in improving its sales in Australia. Firstly, high current market demand for the smartphones presents an opportunity to increase the sales of Samsung Leader 8. Smartphones are currently trending in Australia and other parts of the world. Also, there is an increased demand for the general phones and tablets thus an opportunity to sell Samsung Leader 8. It is also evident that there is a big opportunity for the sale of Samsung Leader 8 which comes from the increased online market. Currently, phone and tablet companies enjoy more sales to the market in Australia and other parts of the world through the use of the online store. There is a growing market of customers who will buy the phone online using internet from wherever they will be located (Valax, 2012). Just like other companies, Samsung also faces threats to its business from different aspects. The main threats to Samsung's Leader 8 are the competition from other industry players. Apple Inc. presents a great competition to Samsung because of commonly known robust IOS (Vrontis Pavlou, 2008). Also, the company's Samsung Leader 8 relies on Google's open-source Android operating system. Thus, this presents a threat to the organization (Helms Nixon, 2010). Samsung Leader 8 faces competition from other industry players. The main competitor is the iPhone produced by Apple. The company has an established robust brand name more than Samsung thus giving competition to Leader 8. Also, there are many companies from China such as Huawei who produce smartphones that suit the customers in Australia and then sells them at a lower price. This has brought about competition in the market. A mission is the company's statement which explains its core functions, the market it targets, the reason why it exists and the organization's competitive advantages in the market. The mission statement is important and helps to communicate valuable information to its stakeholders. Samsung has a mission statement embedded in its philosophy which states a devotion of the company's talent and technology to produce products which are superior in the market contributing to a better global society. Thus, this mission communicates useful information to all the stakeholders of this organization (Hollensen, 2010). Marketing and Financial Objectives There are three main marketing objectives that this plan seeks to achieve. Firstly, it aims at creating the brand awareness of Samsung's Leader 8 in Australia and the rest of the world. Secondly, the plan aims to establish the potential market opportunities for Samsung Leader 8 that exist in Australia. The third marketing objective is to analyze the market competition that exists in the Australian Smartphone industry. These objectives are important and will help Samsung get a direction and focus on the aspects that need to be realized in the endeavor. Therefore, these aims and objectives act as a driver in the exercise (Mintz Currim, 2013). The plan also has three financial objectives. The first financial goal is to increase the organization's income within the next six months. It seeks to find the appropriate strategies that Samsung can employ to attain more revenue. The second financial objective is to achieve a wider profit margin on the sales of the Samsung Leader 8 within the next six months. It attempts to establish best strategies to ensure that the organization reaps the most out from the disposal of the phones. The third objective of this plan is to maximize the number of Samsung Leader 8 devices sold in the next six months. Thus, attaining the financial goals is greatly dependant on the degree to which the marketing objectives have been achieved. The price refers to the amount that the customer pays for the product. Price strategy is one of the key aspects that the organization can use to achieve its financial objectives (Fernie and Moore, 2013). The price of Samsung Leader 8 should be set to be fair to the customers and also be what the company can make a profit. There is need to do price skimming for the Samsung Leader 8. At the launch, the price should be set higher and then reduced as time goes by. Product promotion is one of the inevitable aspects of the successful marketing of a given product (Coman and Ronen, 2009). The various promotion mix that will be employed in the sale of the Samsung Leader 8 includes online promotions, whereby the company will reach the online community from different parts of the world. Besides, the company will use word of mouth to reach other people in the country and also through sponsorship programs (Hartmann, Nair Narayanan, 2011). Samsung can use the aspect of the product to win a huge market share in the industry (Henry, 2011). The company should launch the product in different colors to attract people of various color likes. Besides Samsung Leader 8 shall have other accessories like the earphones and headphones to attract many customers. Place defines the point where the transaction takes place. The company should make a distribution strategy of initially making the product available at the active economic zones and then to the lower ones. This strategy will help the company increase the sale of the phone to people of different economic status (Deng, 2009). There are various activities that Samsung can employ to enhance the marketing mix strategies for their effectiveness. Regarding place or distribution, the company should focus on enhancing the online sales through E-commerce. The organization should also increase the promotions using the digital sources such as Facebook and Twitter and also through their website. Another action program that can help Samsung to achieve its financial objectives is through designing a plan where the sales team move from place to place within Australia. Reaching people in person will leave a greater impact in this marketing exercise. Therefore, Samsung should run different programs to enhance the effectiveness of the exercise and thus, attain its financial and marketing objectives (Chase, Mackillop Hogarth, 2013). Implementation of the marketing plan is one of the key aspects that must be effectively considered for to achieve the marketing and the financial objectives of the company. Successful implementation of the plan relies on how well the marketing team is managed. There should be a clear role distribution in the team so that people handle specific responsibilities. Also, the implementation needs a regular communication strategy which is a critical aspect of effectiveness. Also, a way to exercise control in the exercise, regular monitoring and evaluation should be conducted to establish the state of the practice regularly. Conclusion In conclusion, every business organization needs a marketing for effective marketing of its products. An effective marketing plan should analyze the business environment, to reveal the critical information required to make decisions and take appropriate strategies. There is need to come up with both marketing and financial objectives and thus, implement action programs that will help the company succeed in the sale of products. Thus, a marketing plan is critical to the success of sales for any product or service. References Chase, H., Mackillop, J. Hogarth, L. (2013).
