Definitions of portfolio on the Web:
In finance, a portfolio is a collection of investments held by an institution or a private individual. Holding a portfolio is part of an investment and risk-limiting strategy called diversification. By owning several assets, certain types of risk (in particular specific risk) can be reduced. The assets in the portfolio could include stocks, bonds, options, warants, gold certificates, real estate, futures contracts, production facilities, or any other item that is expected to retain its value.
When it refers to real estate, would that be considered investment real estate only, or primary residence?
