AustralianSuper was the best performer with 10.6 per cent a year over the five-year period.

Australian and overseas equity markets continue to drag down short-term results, particularly listed property investments, which have a large impact on the SelectingSuper Default Option Index.

The best-performing superannuation fund default options are those that have diversified into unlisted assets, particularly those with infrastructure and direct property holdings.

The SelectingSuper Balanced Index, for funds open to the public, was -7.6 per cent for the year to August 31. The three- and five-year periods showed gains of 4.7 per cent a year and 7.5 per cent a year respectively.
