Modern Ethical Theories
Psychological Egoism vs. Ethical Egoism
When we discuss modern ethics there are two theories that emerge above all others and although both are supported they are often controversial in nature. Ethical Egoism states that we should put ourselves and our interests before those of others leading to the conclusion that if we do things that are only in our own self interest then we have achieved morality. Psychological Egoism presumes that we always put ourselves and our interests before others and that every act is motivated only by our own self interest. Even when an act appears on the surface to be totally unselfish it is in all reality a selfish act. Simply feeling good about doing an “unselfish act” makes it selfish. Ethical and Psychological Egoism may seem similar at first glance but they are actually quite different. We will discuss these two theories and their differences, compare the doctrines of motivation for both and discuss selfishness and self interest.
Let’s first take a look at the fallacy of Psychological Egoism. The fallacy of Psychological Egoism is the belief that people are only motivated by self interest but as we all know there are many things that can motivate people to do things. Take for instance the seven deadly sins; sloth, envy, gluttony, lust, anger, greed, and pride. Any one of these can be a motivating factor. So it is easy to see that the fallacy of Psychological Egoism is the erroneous belief that the only motivating factor is self interest. Furthermore you can never know without doubt that you are acting in your definitive self interest because your actions could have undesired results in the future. Psychological Egoism fails without the ‘method of reinterpreting motives’ (Rachels, 1995).
Now that we know the shortcomings of Psychological Egoism let’s discuss the versions of Ethical Egoism. Ethical Egoism

Utilitarianism, Ethical Egoism, and Moral Relativism

...Utilitarianism, Ethical Egoism, and Moral Relativism Tom Gardner Ethics is a branch of philosophy that attempts to answer the questions; what’s right? What’s wrong? And why? Moral relativism is an ethics position that essentially states that people have disagreeing moral beliefs and therefore you must but tolerant of other's morals. This position leads to the problematic realization that if this is the case there can be no objective moral truths nor can there be any universal principles. Act utilitarianism and ethical egoism are two different ethics theories that attempt to respond to this challenge of moral relativism in different ways. Ethical egoism attempts to respond to the challenge of moral relativism by justifying that there is a universal principle for what actions are right and what are wrong. It is a form of consequentialism, which means it looks solely at the consequences of action to see if it is right or wrong. The defining sentence of egoism is as follows, “What's good for you is right and what's bad for you is wrong.” This phrase can be interpreted in a number of ways, the most popular one being: every person should act in their own self-interest. This means that when deciding on whether an action is good, any effect on others (mental or physical) by said action has no merit. An egoist that is measuring or justifying an action's goodness is only examining the possible positive or negative effects this action will have on him. The majority of the justification...

Moral Absolutism

...“Moral relativism is a better system than moral absolutism” Moral relativism refers to the normative ethical system which rejects the idea of absolutes and instead believes that “man is the measure of all things”- which was skilfully expressed by Ruth Benedict. The moral relative system surpasses that of moral absolutism and this will be justified throughout this essay. Moral relativist systems exceed moral absolutist systems due to diversity. The system explains the different values that people hold and encourages diverse cultural expressions due to there being no rigidity or fixe ethical code. This allows for a better system as it signifies freedom of expression and people being able to share their opinions with each other, without there being a ‘right’ or ‘wrong’. This is due to the system prohibiting dominant cultures from enforcing itself over others simply because of a disparity of opinions. This means that all cultures are valued by a relativist as there is no objective knowledge that one must accept, they instead must accept all actions as equally valid in the society in which they take place. This would then make is difficult for a relativist to criticise religious acts such as Muslim women wearing a hijab in England , which is beneficial to society due to the lack of discrimination and ignorance. In conjunction with diversity, moral relativism is a better system than moral absolutism due to circumstantial aspects. Moral absolutism does not take into account the...

Sharp Ratio

...Soundsleep Assignment 2 Subject: Sound sheep funds ranking Per your request, I have compared the five funds based on the sharpe ratio, and Jensen alpha calculations. I also compared the result to the earlier analysis done based on average return, standard deviation and beta. Sharpe ratio, measures investment performance of the portfolio compared to risk taken. It’s most appropriate to use when evaluating diversified portfolios. Sharpe ratio penalizes non-diversified portfolios by also taking into account unsystematic risk. The high sharpe ratio represents the better performance for taking on additional risk. Wallflower Value Fund (WVF) shows the highest performance. The lowest is Mega Multinational Fund (MMF) (figure 1). Figure 1 Jensen's alpha is the excess return above or below the security market line. It can be interpreted as a measure of portfolio’s excess return over the market. A positive alpha shows the portfolio has a relatively high return given its level of systematic risk. Figure 2 below shows that the highest alpha belongs to WVF. Figure 2 In both ranking Wallflower Fund is showing the best return. The same reasoning was established when assessing the portfolio based on the average return, beta and stdev in the past. The beta of the fund is close to 1.0, the slope beta is slightly above 1.0, the Stdev relative to the average return is reasonable. Base on the alpha and sharpe’s calculation, the fund is receiving a high return while managing...

Stock Investment Analysis

...Fidelity Large Cap Stock Fund and S&P 500 are similar funds. These two funds heavily invest in large market capitalization company common stock, topping 80% of its entire portfolio. Fidelity Large Cap Stock Fund consists of normally 11 different sectors for equities listed in highest portfolio weight with first five sectors making 80% of the portfolio: • Financials • Information Technology • Health Care • Energy • Industrials • Consumer Discretionary • Consumer Staples • Telecommunication Services • Materials • Utilities • Other Current year-to-date performance of the Fidelity Large Cap Stock Fund (FLCSX) was overall positive at 16.24% year-to-date return. The financial sector contributed and played a big part in making the successful performance this year resulting from a good portfolio mixture of securities and its positive gain. This mixture consists of some of the high return securities such as; JPMorgan Chase, MetLife and Charles Schwab returning, 29.38%, 48.68% and 54.99% respectively. The historic performance has shown that both MetLife and Charles Schwab performed well responding to the rising interest rates, and these two companies did not fail to positively react to the recent increase in interest rates. Both companies’ share price went up by more than 20%. Thanks to the uptick in interest rates due to many speculation of slow economy recovery in the market. S&P 500 also had a strong year-to-date return at 13.82%. Both FLCSX and S&P 500 topped...

Types of Risk

...systematic risk and unsystematic risk In finance, systematic risk, sometimes called market risk, aggregate risk, or undiversifiable risk, is the risk associated with aggregate market returns. By contrast, unsystematic risk, sometimes called specific risk, idiosyncratic risk, residual risk, or diversifiable risk, is the company-specific or industry-specific risk in a portfolio, which is uncorrelated with aggregate market returns. Unsystematic risk can be mitigated through diversification, and systematic risk can not be.[1] Systematic risk should not be confused with systemic risk, the risk of loss from some catastrophic event that collapses the entire financial system. Contents [hide] * 1 Example * 2 Systematic risk and portfolio agement * 3 References * 4 See also | ------------------------------------------------- [edit]Example For example, consider an individual investor who purchases $10,000 of stock in 10 biotechnology companies. If unforeseen events cause a catastrophic setback and one or two companies' stock prices drop, the investor incurs a loss. On the other hand, an investor who purchases $100,000 in a single biotechnology company would incur ten times the loss from such an event. The second investor's portfolio has more unsystematic risk than the diversified portfolio. Finally, if the setback were to affect the entire industry instead, the investors would incur similar losses, due to systematic risk. Systematic Risk: It is the risk which is due to...

Chapter 6

...Chapter 06 Efficient Diversification 1. So long as the correlation coefficient is below 1.0, the portfolio will benefit from diversification because returns on component securities will not move in perfect lockstep. The portfolio standard deviation will be less than a weighted average of the standard deviations of the component securities. 2. The covariance with the other assets is more important. Diversification is accomplished via correlation with other assets. Covariance helps determine that number. 3. a and b will have the same impact of increasing the Sharpe ratio from .40 to .45. 4. The expected return of the portfolio will be impacted if the asset allocation is changed. Since the expected return of the portfolio is the first item in the numerator of the Sharpe ratio, the ratio will be changed. 5. Total variance = Systematic variance + Residual variance = β2 Var(rM) + Var(e) When β = 1.5 and σ(e) = .3, variance = 1.52 × .22 + .32 = .18. In the other scenarios: a. Both will have the same impact. Total variance will increase from .18 to .1989. b. Even though the increase in the total variability of the stock is the same in either scenario, the increase in residual risk will have less impact on portfolio volatility. This is because residual risk is diversifiable. In contrast, the increase in beta increases systematic risk, which is perfectly correlated with the market-index portfolio and therefore has a greater impact on portfolio...

History of the Capm Model

...All of the models to be discussed, i.e. Markowitz, Single Index, CAPM, and APT, have one single goal that is accomplished by using them. This goal is to make a portfolio, or individual securities, as efficient and well performing as possible by finding the optimal weights, highest return, and lowest risk. The Harry Markowitz model of 1952, or the mean-variance model, was one of the earliest models created to compare and contrast securities outcomes. This model uses the weights, standard deviation, and covariance for each security, creating a weighted covariance matrix, therefore forecasting a very accurate estimate of what return and risk the securities or portfolio would give. The Single-Index model, introduced by William Sharpe in 1963, is a simplified variation of the Markowitz model. Using the same premise of estimating in order to forecast optimal portfolios and securities, the single-index model instead uses beta and alpha substitutes for the standard deviation and covariance portions. Beta, measures the volatility of the portfolio or security comparatively to the market as a whole, i.e. the sensitivity to the market, and alpha, measures risk-adjusted performance (comparative to the appropriate benchmarks). These two combined simplify the process of the Markowitz model, while still gaining a result of the optimal portfolio. The Capital Asset Pricing model, or ‘CAPM’, produced by John Lintner in 1965, is a product that branched from the Single-Index model. While it does...

Diversification

...Priest J. Gordon FIN 6300 – Managerial Finance West Texas A&M University Spring 2013 Diversification 1. According to the article, what is a personal beta? (4 points) A personal beta is one’s professional sensitivity to the stock market. 2. List one job you think would create the highest personal betas (4 points) and one job that would create the lowest personal betas(4 points). Briefly explain your choices. (4 points) A commission stock broker or financial advisor would have an extremely high beta considering that their profession is 100% tied to the stock market. Conversely, a Civil Engineer working for the Corps of Engineers would have no professional relation to the stock market and therefore a very low beta. 3. According to the article, use no more than two sentences to explain how a person with high personal beta should invest her financial capital? (4 points) She should withdraw from the stock market and look at other low risk opportunities. Her high beta exposes her to too much risk already before she invests any capital. 4. How does the weather in the United States last year compare to normal? (4 points) According to the article, who benefits and who loses because of this weather?

Finaince Case 3

...FIN 475 Spring 2014 Cases in Financial Management Case 2 Prepared For Dr. Haskins By Kaylynn Burgess, Cody Jochim, and Richard Caldecott February 20, 2014 1. The case gave a table that had the rate or return under certain conditions and from that we found the expected returns, standard deviations, and coefficients of variations for the assets. For the expected returns we took the probability and multiplied that by the rate of return for each type of economy, and then added them all up. To get standard deviation you must first calculate the variance. For that we took the rate of return minus expected return, squared that difference, multiplied that by the probability, and then summed them up. The get the standard deviation we took the square root of the variance. To get the coefficient of variations we took the standard deviation and divided it by the expected return. | T-Bills | Market | Games Inc. | Outplace Inc. | Expected Return | 6% | 10% | 13% | 12% | Standard Deviation | .03824 | .0875 | .2259 | .1308 | CV | .6374 | .8746 | 1.7374 | 1.0897 | We ranked the assets from least risky to most risky by their standard deviation and coefficient of variation and the ranks were the same. The T-Bills were the least risky followed by the market, Outplace Inc., and then Games Inc. In the investing world, the coefficient of variation allows you to determine how much risk you are assuming in comparison to the amount of return you can expect from your investment...

The SDF can be derived from the utility function, this gives: . The problem with this is determining marginal utility.
