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 ...
Economist Harry Markowitz introduced MPT in a 1952 paper, [1] for which he was later awarded a Nobel Memorial Prize in Economic Sciences; see Markowitz model. In 1940, Bruno de Finetti published [4] the mean-variance analysis method, in the context of proportional reinsurance, under a stronger assumption. The paper was obscure and only became ...
Modern portfolio theory was introduced in a 1952 doctoral thesis by Harry Markowitz, where the Markowitz model was first defined. [1] [2] The model assumes that an investor aims to maximize a portfolio's expected return contingent on a prescribed amount of risk. Portfolios that meet this criterion, i.e., maximize the expected return given a ...
The hyperbola is sometimes referred to as the "Markowitz bullet", and its upward sloped portion is the efficient frontier if no risk-free asset is available. With a risk-free asset, the straight capital allocation line is the efficient frontier.

Harry Markowitz laid the foundations of MPT, the greatest contribution of which is [citation needed] the establishment of a formal risk/return framework for investment decision-making; see Markowitz model. By defining investment risk in quantitative terms, Markowitz gave investors a mathematical approach to asset-selection and portfolio ...
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 to assets with better estimated than true risk/return characteristics.
