The standard form of the Omega ratio is a non-convex function, but it is possible to optimize a transformed version using linear programming. [4] To begin with, Kapsos et al. show that the Omega ratio of a portfolio is: = [() +] + The optimization problem that maximizes the Omega ratio is given by: [() +], (), =, The objective function is non-convex, so several ...
The consumption-based capital asset pricing model (CCAPM) is a model of the determination of expected (i.e. required) return on an investment. [1] The foundations of this concept were laid by the research of Robert Lucas (1978) and Douglas Breeden (1979). [2] The model is a generalization of the capital asset pricing model (CAPM). While the ...
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.
Assets are divided into classes by type of asset or by business in which the asset is used. (See tables of classes below.) Where a general class based on the nature of the asset applies (00.xx classes below), that class takes precedence over the use class. For each class, three lives are specified: one for regular depreciation (GDS in the ...
A chart of accounts (COA) is a list of financial accounts and reference numbers, grouped into categories, such as assets, liabilities, equity, revenue and expenses, and used for recording transactions in the organization's general ledger.
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 .
In finance, YTD figures are often included in financial statements to detail the performance of a business entity. Providing YTD results for the current year, as well as for one or more past years as of the same date, allows owners, managers, investors, and other stakeholders to compare the company's current performance with that of previous ...
A stochastic investment model tries to forecast how returns and prices on different assets or asset classes, (e. g. equities or bonds) vary over time. Stochastic models are not applied for making point estimation rather interval estimation and they use different stochastic processes.
