Abstract
This essay is concerned with understanding the key issues relative to portfolio analysis and investment. The scope of this essay will be limited to the U. S. Stock markets only. This essay will be built upon extant portfolio theory and will discuss different types of risks that investors might face and how they go about managing such risks. Under consideration will be topics such as efficient frontier and optimal portfolios as well as their relevance to investment theory, under the assumption of direct investment in the stock market.

DETERMINING THE PURPOSE OF YOUR INVESTMENT
One of the steps in building an investment portfolio is to establish investment goals. Investment goals are the financial objectives you wish to achieve by investing (Gitman and Joehnk, 2005). In other words, what you want these investments to do for you or why you are investing in the first place. Some common investment goals include (Gitman, et al, 2005): 1) accumulating retirement funds, 2) enhancing current income, 3) saving for major expenditures, or 4) sheltering income from taxes. To get an estimate of the securities suitable for certain levels of risk tolerance and to maximize returns, investors should have an idea of how much time and money they have to invest and the returns they are looking for (Investopedia.com, 2006).

MODERN INVESTMENT THEORY
Modern Investment Theory also known as Modern Portfolio Theory (MPT) was introduced by Harry Markowitz with his paper “Portfolio Selection,” which appeared in the 1952 Journal of Finance (riskglossary.com, 2006). Prior to Markowitzs work, investors focused on assessing the risks and rewards of individual securities that offered the best opportunities for gain with the least risk and then construct a portfolio from these (riskglossary.com, 2006).

MPT is defined, according to investorwords.com (2005), as an overall investment strategy that seeks to construct an optimal portfolio by considering the relationship between risk and return, especially measured by alpha, beta, and RІ. MPT utilizes several basic statistical measures to develop a portfolio plan (Gitman, et al, 2005). Included are expected returns and standard deviations of returns for both securities and portfolios, and the correlation between returns (Gitman, et al, 2005). Detailing the mathematics of diversification, Markowitz proposed that investors focus on selecting portfolios based on their overall risk-reward characteristics instead of merely compiling portfolios from securities that individually have attractive risk-reward characteristics (riskglossary.com, 2006). This theory proposes that the risk of a particular stock should not be looked at on a standalone basis, but rather in relation to how that particular stocks price varies in relation to the variation in price of the market portfolio (investorwords.com, 2005). The theory goes on to state that given an investors preferred level of risk, a particular portfolio can be constructed that maximizes expected return for that level of risk (investorwords.com, 2005).

The MPT model assumes that investors are risk averse (Wikipedia.com, 2006). This means that given two assets that offer the same return, investors will prefer the less risky one (Wikipedia.com, 2006). Thus, an investor will take on increased risk only if compensated by higher expected returns (Wikipedia.com, 2006). Conversely, an investor who wants higher returns must accept more risk (Wikipedia.com, 2006). The implication is that a rational investor will not invest in a portfolio if a second portfolio exists with a more favorable risk-return profile (Wikipedia.com 2006). Two important aspects of MPT are the efficient frontier and portfolio betas (Gitman, et al, 2005).

THE EFFICIENT FRONTIER
The efficient frontier can, in theory, be used to find the highest level of satisfaction the investor can achieve given the available set of portfolios (Gitman, et al, 2005). This concept considers a multitude of risky investments and explores what might be an optimal portfolio based upon those possible investments. An optimal portfolio is such that it “provides the highest return for a given level of risk or provides minimum risk for a given level of return (Gitman, et al, 2005); achieving the best possible trade-off between risk and return. The notion of “optimal” portfolio can be defined in one of two ways (riskglossary.com, 2006):

Definition 1 produces an optimal portfolio for each possible level of risk: for any level of volatility, consider all the portfolios which have that volatility. From among them all, select the one which has the highest expected return.

Definition 2 produces an optimal portfolio for each expected return: for any expected return, consider all the portfolios which have that expected return. From among them all, select the one which has the lowest volatility.

Each definition produces a set of optimal portfolios (riskglossary.com, 2006). That set of optimal portfolios is called the efficient frontier (riskglossary.com, 2006). The trade-off between risk and return, within the efficient frontier, requires that more risk be accepted in return for the chance to earn a higher rate of return. The exact trade-off will differ by investor (Wikipedia.com, 2006).

DIFFERENT TYPES OF RISK
The risk associated with any given investment vehicle may result from a combination of possible sources (Gitman, et al, 2005). Those sources include business risk, financial risk, purchasing power risk, interest rate risk, liquidity, risk, tax risk, market risk, event risk, and currency exchange risk. Thoughtful investment selections that meet your goals and risk profile keep individual stock and bond risks at an acceptable level (Little, 2006). Most of the risks affect the market or economy and require investors to adjust portfolios or ride out the storm (Little, 2006).

Business risk–is the degree of uncertainty associated with an investments earnings and the investments ability to pay the returns (interest, principal, dividends) owed investors (Gitman, et al, 2005). Much of the business risk associated with a given investment vehicle is related to its kind of business (Gitman, et al, 2005).

Financial risk–is the degree of uncertainty of payment attributable to the mix of debt and equity used to finance a business (Gitman, et al, 2005). The larger
