If we drop this ‘inefficient’ part of the frontier, what’s left is the efficient frontier or Markowitz frontier. The standard deviation is lowest when both stocks are perfectly negatively correlated ( = -1), and highest when we have perfect positive autocorrelation ( = 1). table#t5 tbody tr.table-alternate { } Game-theoretic methods are not widespread in finance. In finance, the Markowitz model - put forward by Harry Markowitz in 1952 - is a portfolio optimization model; it assists in the selection of the most efficient portfolio by analyzing various possible portfolios of the given securities. PSSgives the investor the ability to efficiently achieve market timing and optimal diversification by applying digital signal processing to the classical Modern Portfolio Theory portfolio selection … } The investors knew that diversification is best for making investments but Markowitz formally built the quantified concept of diversification. 12 0 obj<>>>  The model is describing under the framework of a risk-return tradeoff graph. As a descriptive framework of how we make choices in the face of risk and uncertainty. Introduction to Portfolio Theory Updated: August 9, 2013. Portfolio optimization models are used to guide an investor's selection of financial assets. border-collapse: collapse; Markowitz Portfolio Theory is helpful in selection of portfolio in such a way that the portfolios should be evaluated by the investor on the basis of their expected return and risk as measured by the standard deviation. More useful models have however been developed from the Markowitz model by use of approximation. We can illustrate the effect of correlation on diversification using a simple table. margin: 20px 0; table#t6 tbody tr td#n1 { Portfolio • A portfolio is a grouping of financial assets such as stocks, bonds, cash equivalents as well as their mutual, exchange –traded and closed-fund counterparts.

This is very simple, as it is just the weighted average of the expected returns of the companies’ stocks included in the portfolio. Suppose we invest 50% in each of the two companies’ stock. He proved that investors who take a higher risk can also achieve higher profit. To build an efficient portfolio an expected return level is chosen, and assets are substituted until the portfolio combination with the smallest variance at the return level is found.
