Reducing the Dispersion of Returns in Uk Real Estate Portfolios

This is the authors' abstract. We don't add key points for this paper.

Although real estate represents a substantial proportion of the UK investment market, research in this area is extremely limited. This is particularly true of the performance and construction of portfolios. This paper deals with one of the major issues which confronts both investor and advisor; namely, how effective is the diversification of a real estate portfolio as more properties are included. The analysis is undertaken at an empirical level and draws on similar research developed in the stock market. The main findings are that the low correlation between returns on individual properties enable high levels of risk reduction to be achieved. This correlation structure does, however, impose a penalty making it extremely difficult to construct highly diversified portfolios. The problem is exacerbated by the indivisibility of real estate assets.
