Long Term GMI Performance

We update our returns annually so our clients can judge the consistency of our performance. However, don’t forget the cliché – past performance is not necessarily an indicator of future performance, especially in the shorter term.


GMI Growth portfolio average: Here we define Growth portfolios as having more than 65% in growth assets, i.e. less than 35% of funds mandated to fixed interest or income stocks.

Average GMI Growth benchmark: Each GMI client has their own benchmark based on their particular asset mix. The benchmark we show here is based on an average of these benchmarks.


A $1,000 investment in an average GMI Growth portfolio in 2002 has, over the last 10 years, compounded to NZ $1,708.

Over this particular period that’s an average return – after fees, brokerage and tax – of 5% per annum compared to the relevant benchmark return of 1.2% per annum. The global financial crisis and its aftermath have put a real dent in performance over this period.

The next graph gives the year-by-year performance of those Growth portfolios and contrasts it with the benchmark performance. It is evident that out-performance has come as much from minimising damage in down years as scoring out-performance in the up years. That was especially evident during the 2007-2009 credit crisis.

As the graph above illustrates, over the past 10 years our Growth portfolios have out-performed the benchmark for 9 of them.
