A portfolio whose composition is exogenously (externally) determined. In other words, an exogenous portfolio is constructed from components selected using a market-tracking collection of assets or an indexed collection. The performance of such a portfolio depends on the performance its external components and the inter-links amongst such components.
It may also imply the situation where a portfolio is based, in terms of its structure, on exogenous resources, rather than internally sourced financial components (as opposed to an endogenous portfolio), such as equity or equity instruments, etc.
