Package org.ojalgo.data.domain.finance.portfolio

Classes in this package relate to modelling of financial investment portfolios, and Modern Portfolio Theory.
  • An asset is a resource with economic value, and something that can be owned.
  • A portfolio is a collection of something (anything).
  • An instrument is a tool or device - an enabler.
  • Financial instruments enable financial transactions, and are defined in terms of assets. A financial instrument can for instance be evidence of ownership of, or a contractual right/obligation to receive or deliver, an asset.
  • Financial portfolios contain financial instruments. Typically, in terms of investments, it is a collection of assets with a common owner.
  • The distiction between assets, instruments and portfolios is fuzzy, and the terms can often be used interchangeably. Here the term portfolio represents the collection and ownership, and the term asset represents components/contents and underlying value. We try to avoid using the term instrument.
