Jeremy Sullivan, investment adviser with Hamilton Hindin Greene, puts the index's poor performance down to the slide in prices of Meridian, Contact and a2 Milk.
"The large companies have been pushed around," he said. "Meridian and Contact were bid up by the passive investment funds and then the global clean energy index was rebalanced, to their detriment. And a2 Milk has been sliding most of the year."
Meridian, which reached $9.40 in January, was down 3.5c to $4.865 and has fallen 11 per cent over the past 12 months. Contact, surging to $10.75 in January, gained 6c to $8.16 and is up more than 7 per cent for the past year.
Global marketer a2 Milk recovered 7c $6.31, and is down 59.5 per cent over the past 12 months.
Sullivan said the markets both here and overseas were steadied by the United States Senate agreement to increase the debt ceiling by US$480 billion ($692b) through to December.
"The headwind for the market now is rising interest rates, and this won't help the income stocks like energy and property," he said.
