Modern Portfolio Theory
INTRODUCTION:
The investment terrain has seen some major changes in the last two decades. Financial and technology companies came and went, stock market values soared, plummeted and rebounded, housing derivatives blew up, and other foundations were laid bare. Even the core of investing theories related to portfolios has come under pressure. Yet the belief in Modern Portfolio Theory has remained strong amongst the investors.
Modern Portfolio Theory (MPT) is a theory that tells investors how to minimise risks associated with investment and at the same time, maximise return on the investments by proper resource allocation and diversifying their portfolios – it is based on the theory that risk can be lessened by diversifying into uncorrelated asset classes. However, unless the correlations of the various asset classes are predictable, the reduction of risk may be lost.
Investors expect to be rewarded for the level of risk they are taking in a particular market. According to the theory, it's possible to construct an "efficient frontier" of optimal portfolios offering the maximum possible expected return for a given level of risk and there are four basic steps involved in portfolio construction: Security Valuation, Asset Allocation, Portfolio Optimization and Performance measurement.
This theory of portfolio selection was coined by Harry Markowitz in his paper ‘Portfolio Selection’ which was published in the Journal of Finance in March, 1952. Even before Markowitz in 1952, investors were familiar with the notion being able to reduce exposure to risk by diversifying their portfolios. The proverb ‘never put all your eggs in one basket’ underlies this idea. Through his paper, Markowitz was able to use a mathematical framework to study the effects of asset risk, return, correlation and diversification on probable portfolio returns and was awarded the John von Neumann Theory Prize and the Nobel Memorial Prize in Economic Sciences.

    One basic assumption of portfolio theory is that as an investor you want to maximize the returns from your total set of investments for a given level of risk. The full spectrum of investments must be considered because the returns from all these investments interact, and this relationship among the returns for assets in the portfolio is important. Hence, a good portfolio is not simply a collection of individually good investments. There are several risks that are associated with the stocks and assets. So as to averse the risk the investor focuses on building up a diversified group of assets which helps in mitigating the risk of the total investment.…

    Investing in the total stock market allows an investor to capture the return of the stock market while at the same time diversifying an investment portfolio. The easiest way to build a total stock market portfolio is with a mutual fund or an exchange traded fund. This particular portfolio is diversified with Vanguard ETF’s that were carefully chosen to seek the highest return with moderately aggressive to aggressive risk strategy. The investment strategy associated with this portfolio is short-term with an aggressive attitude of “more risk more reward”.…

    Within any investment there is a certain amount of risk, which must be taken into account by an investor when deciding to invest. Risk is defined as the chance of financial loss or, more formally the variability of returns associated with a given asset. (Gitman, et al., 2011, p. 208) This concept in finance is the idea that all investment carries a risk, the higher the risk, the greater the return, however the adverse is also relevant, when the risk of an investment is lower the return is expected to also be lower. However, with all investment there is never a guarantee of return.…

    Assets allocation is the most import and technical step for investors when they want to invest in the financial market. This report will give an example of how to use Portfolio Theory and the Efficient Frontier to distribute weight among the selected 20 stocks to make an optimal portfolio. Lastly, it will compare the six constructed models and find the best one. There are some terms that will be used in this report. Efficient frontier is be used by rational investor to choose the best combination of risk and return among all possible combinations (Essential Investment,2003).Optimal market portfolio is regarded by Doeswijk, Lam and Swinkels (2012) as the best choose or benchmark choose of portfolio for any ordinary investor because it includes all assets’ value among the market.Minimum variance portfolio (MVP) focuses on the goal of reaching the lowest risk through determining appropriate weight of each asset. “MVPs illustrated returns similar to their benchmark capitalization weighted indices but with 25-30% lower standard deviation.”(Haugen and Baker (1991), Clarke, Silva, and Thorley (2006), and Poullaouec (2008) cited in Bausys)…

    Mean Variance Optimization

    • 2062 Words
    • 9 Pages

    The mean-variance theory postulated that in determining a strategic asset allocation an investor should choose from among the efficient portfolios consistent with that investor’s risk tolerance amongst other constraints and objectives. Efficient portfolios make efficient use of risk by offering the maximum expected return for specific level of variance or standard deviation of return. Therefore, the asset returns are considered to be normally distributed. Efficient portfolios plot graphically on the efficient frontier, which is part of the minimum-variance frontier (MVF). Each portfolio on the minimum-variance frontier represents the portfolio with the smallest variance of return for given level of expected return. The graph of a minimum-variance frontier has a turning point that represents the Global Minimum Variance (GMV) portfolio that has the smallest variance of all the minimum-variance portfolios. Economists often say that portfolios located below the GMV portfolio are dominated by others that have the same variances but higher expected returns. Because these dominated portfolios use risk inefficiently, they are inefficient portfolios. The portion of…

    The primary reason for investing in portfolios is diversification, that is, the allocation of funds to a variety of securities in order to reduce risk. As the number of securities held in the portfolio increases, the overall variability of the portfolio’s return, measured by its standard deviation, diminishes very sharply for small portfolios, but falls more gradually for larger combinations. This decline in risk is achieved because the exposure to the risk of volatile securities can be offset by the inclusion of low-risk securities or even high-risk ones, so long as their returns are not closely…

    Prior to 1952, investment theories had ignored this very important relationship between risk and return. Harry Markowitz gave a “formal confirmation of two old rules of investing: Nothing ventured, nothing gained. Don’t put all your eggs in one basket.” (44) Markowitz recognized that focusing on return, without risk, leads to suboptimal portfolio selection. He concluded that the only way to minimize risk is to select a diversified portfolio of assets with low covariance. His findings led to the idea of the efficient portfolio, which offers the highest expected return for any given degree of risk. To find this so-called efficient portfolio, one must estimate variance and expected returns of securities, which proved to be a difficult task for investors at a time when computer availability was scarce. Nevertheless, Markowitz put a system in place for assembling portfolios and formed the foundation for all future theories.…

    “A portfolio strategy designed to reduce exposure to risk by combining a variety of investments, such as stocks, bonds, and real estate, which are unlikely to all move in the same direction. The goal of diversification is to reduce the risk in a portfolio.” (2008). In a perfect world, a diversified portfolio would receive returns on all of their investments, including stocks, bonds, and real estate but this is the game all investors make when trying to predict which investments will be successful. It is understood that increased diversification leads to higher levels of economic stability and performance. For example, a well-diversified country would not sink all of their investments into just one type. Putting all of their monies into stocks would not be a good risk. The stock market is too volatile and unpredictable. One could lose everything they have invested for many reason. It is amazing to see how stocks can be affected by a war or even new legislation. The investor is also wise for investing in many different stock options. Keeping it broad helps reduce the exposure to high risks. There are many different indicators used to make these decisions.…
