Not-for-profit superannuation funds have dramatically outperformed for-profit retail funds, taking the first 23 of the top 30 positions over 10 years to September 2017, according to new research from SuperRatings.

Not-for-profit industry funds overall made up 25 of the top 30 performing funds. And details on investment strategies of different fund types provided by SuperRatings helps explain why that is the case.

The top performing fund, REST, returned members 6.1 per cent annually over a decade while the top retail fund, Russell IQ, returned 4.4 per cent.
