(2009). Specific risk is also called diversifiable, unique, unsystematic, or idiosyncratic risk. Modern portfolio theory back to the 1950s and is one of the most important theories of investment management.
Modern portfolio theory (MPT), or mean-variance analysis, is a mathematical framework for assembling a portfolio of assets such that the expected return is maximized for a given level of risk. Modern Portfolio Theory (MPT) is a method to select which stocks and what amounts to buy such that as a group, these stocks give the highest amount of returns for a given amount of risk. In this article, risk is defined as the volatility[2] of your returns[1]. For example, suppose Portfolio A has an expected return of 8.5% and a standard deviation of 8%. For given portfolio weights and given standard deviations of asset returns, the case of all correlations being 1 gives the highest possible standard deviation of portfolio return. It is a formalization and extension of diversification in investing, the idea that owning different kinds of financial assets is less risky than owning only one type.

It’s become such an integral part of modern investment that it won a Nobel Prize in 1990. The Sharpe ratio is used to help investors understand the return of an investment compared to its risk.How to Use the Sharpe Ratio to Analyze Portfolio Risk and Return All investments or securities are subject to systematic risk and therefore, it is a non-diversifiable risk.Portfolio variance is a statistical value that assesses the degree of dispersion of the returns of a portfolio. To calculate the risk of a four-asset portfolio, an investor needs each of the four assets' variances and six correlation values, since there are six possible two-asset combinations with four assets. Modern portfolio theory is inconsistent with main axioms of In the 1970s, concepts from MPT found their way into the field of More recently, modern portfolio theory has been used to model the self-concept in social psychology. In other words, when variable A increases, variable B decreases. Modern Portfolio Theory (MPT) Understanding Modern Portfolio Theory (MPT). The Capital Allocation Line (CAL) is a line that graphically depicts the risk-and-reward profile of risky assets, and can be used to find the optimal portfolio.The Certified Banking & Credit Analyst (CBCA)™ accreditation is a global standard for credit analysts that covers finance, accounting, credit analysis, cash flow analysis, covenant modeling, loan repayments, and more. Specific risk is the risk associated with individual assets - within a portfolio these risks can be reduced through diversification (specific risks "cancel out"). In addition, the less correlated each asset is to the others, the less net risk the portfolio has overall. The concept of capturing the risk tolerance of an investor by documenting how much risk is acceptable for a given return may be applied to a variety of decision analysis problems. In this article, risk is defined as the volatility of your returns. What the theory says is that if you combine asset classes that zig and zag (and possibly zog) in a portfolio, even though each asset class by itself may be quite volatile, the volatility of the entire portfolio can be quite low. It helps the investor hold fast to a strategy rather than get carried away with market hype.Owen Murray, director of investments for Horizon Advisors, says modern portfolio theory is a how-to guide for minimizing portfolio risk. "It is a tried-and-true classic, and is extremely relevant for long-term investors today," says Mike Loewengart, vice president of investment strategy at E-Trade. The slope of the CAL is called the Sharpe ratio, which is the increase in expected return per additional unit of standard deviation (reward-to-risk ratio).In the chart above, at point “B,” the reward-to-risk ratio (the slope of the CAL) is the highest, and it is the combination that creates the optimal portfolio according to the MPT.Further information on how to calculate the efficient frontier and capital allocation line can be found in According to the MPT, rational risk-averse investors should hold portfolios that fall on the efficient frontier (since they provide the highest possible expected returns for a given level of standard deviation). Returns are the money made or lost over a period of time. The power of diversification allows investors to theoretically reduce the risk of a portfolio while preserving its potential return.Modern portfolio theory incorporates a number of correlation and risk metrics, including alpha, beta, standard deviation, R-squared and Sharpe ratio.
