Portfolio optimization often takes place in two stages: optimizing weights of asset classes to hold, and optimizing weights of assets within the same asset class. An example of the former would be choosing the proportions placed in equities versus bonds, while an example of the latter would be choosing the proportions of the stock sub-portfolio ...
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.

In general, when there are portfolio constraints – for example, when short sales are not allowed – the easiest way to find the optimal portfolio is to use the Black–Litterman model to generate the expected returns for the assets, and then use a mean-variance optimizer to solve the constrained optimization problem.
Marketing decisions have an obvious potential connection to the numerator of ROI (profits), but these same decisions often influence assets’ usage and capital requirements (for example, receivables and inventories). Marketers should understand the position of their company and the returns expected. [3]
Performance attribution, or investment performance attribution is a set of techniques that performance analysts use to explain why a portfolio's performance differed from the benchmark. This difference between the portfolio return and the benchmark return is known as the active return .
Asset classes and asset class categories are often mixed together. In other words, describing large-cap stocks or short-term bonds as asset classes is incorrect. These investment vehicles are asset class categories, and are used for diversification purposes. Multiple asset classes mixed together in a fund structure can provide an investor with ...
Arrange the returns of N risky assets in an vector , where the first element is the return of the first asset, the second element of the second asset, and so on. Arrange their expected returns in a column vector μ {\displaystyle \mu } , and their variances and covariances in a covariance matrix Σ {\displaystyle \Sigma } .
A key component of private equity as an asset class for institutional investors is that investments are typically realized after some period of time, which will vary depending on the investment strategy. Private-equity investment returns are typically realized through one of the following avenues:
