European pension funds are displaying an increased appetite for alternative investments, including real estate, according to the results of the 2010 European Institutional Asset Management Survey (EIAMS) published by Invesco on Tuesday. The findings point to an altogether more positive sentiment among institutional investors in 2009 compared to the previous year, which has benefited riskier asset classes in particular. The focus of the survey is on small to medium-sized investors, with pension funds making up 98% of the sample.
