This is an example of a multi-objective optimization problem: many efficient solutions are available and the preferred solution must be selected by considering a tradeoff between risk and return. In particular, a portfolio A is dominated by another portfolio A' if A' has a greater expected gain and a lesser risk than A.
Example investment portfolio with a diverse asset allocation. Asset allocation is the implementation of an investment strategy that attempts to balance risk versus reward by adjusting the percentage of each asset in an investment portfolio according to the investor's risk tolerance, goals and investment time frame.

Modern portfolio theory is inconsistent with main axioms of rational choice theory, most notably with monotonicity axiom, stating that, if investing into portfolio X will, with probability one, return more money than investing into portfolio Y, then a rational investor should prefer X to Y.
For example, a goal of earning 1% in every month of one year results in a greater risk than the seemingly equivalent goal of earning 12% in one year. 2. A second reason for strongly preferring the continuous form to the discrete form has been proposed by Sortino & Forsey (1996):
In Figure 1, the shaded area PVWP includes all the possible securities an investor can invest in. The efficient portfolios are the ones that lie on the boundary of PQVW. For example, at risk level x 2, there are three portfolios S, T, U. But portfolio S is called the efficient portfolio as it has the highest return, y 2, compared to T and U ...
So in conclusion, once again, I'm proud of the accomplishments of the entire organization. Our portfolio is well positioned to generate competitive returns and cash flow for decades to come.
For example, a globally invested pension fund must choose how much to allocate to each major country or region. In principle modern portfolio theory (the mean-variance approach of Markowitz) offers a solution to this problem once the expected returns and covariances of the assets are known. While modern portfolio theory is an important ...
