Portfolio optimization is the process of selecting an optimal portfolio (asset distribution), out of a set of considered portfolios, according to some objective. The objective typically maximizes factors such as expected return , and minimizes costs like financial risk , resulting in a multi-objective optimization problem.
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. Here, by choosing securities that do not 'move' exactly together, the HM model shows investors how to ...
A portfolio optimization method would have to take the discrete nature of projects into account. The assets of financial portfolios are liquid; they can be assessed or re-assessed at any point in time.
Hierarchical Risk Parity (HRP) is an advanced investment portfolio optimization framework developed in 2016 to compete with the prevailing mean-variance optimization (MVO) framework developed by Harry Markowitz in 1952, and for which he received the Nobel Prize in economic sciences. [1]
Merton's portfolio problem is a problem in continuous-time finance and in particular intertemporal portfolio choice. An investor must choose how much to consume and must allocate their wealth between stocks and a risk-free asset so as to maximize expected utility .

His portfolio optimization method finds the minimum risk portfolio with a given expected return. [2] Because the Markowitz or Mean-Variance Efficient Portfolio is calculated from the sample mean and covariance , which are likely different from the population mean and covariance , the resulting investment portfolio may allocate too much weight ...
In finance, the Black–Litterman model is a mathematical model for portfolio allocation developed in 1990 at Goldman Sachs by Fischer Black and Robert Litterman. It seeks to overcome problems that institutional investors have encountered in applying modern portfolio theory in practice. The model starts with an asset allocation based on the ...
