Abstract
Diversifying an investment portfolio through the diversification of assets, which is accompanied by the dispersion of risk, is aimed at achieving an appropriate balance between the expected return and an acceptable level of investment risk. While considering the specificity of various forms of investing in property, the level of the liquidity risk of property assets and the risk of financial instruments in the real estate market, as well as the volume of the capital involved and the regional differentiation of its allocation, this paper intends to present the possible ways of diversifying the portfolio, including sectoral and geographical diversification on the assumption that investments are concentrated in metropolitan areas. The identification of investment portfolio diversification principles, including liquid assets and the real estate market, embraces this perspective on the conditions of the functioning of EU REITs, whose business goal is to manage professionally diversified real estate portfolios
