What is a Portfolio in LUSID?

LUSID supports various types of portfolios, allowing the to enable the management of indexes, to build and maintain custom benchmarks and to support what if analysis with the need to duplicate portfolios.

LUSID supports the following types of portfolios:

All portfolios are in a scope and are identified by a client supplied code that is unique within that scope.

Transaction Portfolio – Contain transactions which are used to construct the portfolio holdings on which valuations, analytics, profit & loss and risk can be calculated.

Derived Transaction Portfolio – A portfolio can derive from another portfolio

Reference Portfolio – Contain a list of instruments and associated weights as percentages, as opposed to transactions, and are designed to represent entities such as indices.

All portfolios are comprised of:

  • Details - which represent the economically impacting settings e.g. the base currency
  • Properties - Properties can be associated with a portfolio, and changed over time, for example, to allow a Portfolio Manager to be linked with a Portfolio.
  • Contents such as transactions, holdings or the ruleset definition

Portfolios can be securitised to become instruments themselves and held by other portfolios. This allows LUSID® to perform "drill-through" into underlying fund holdings.
