"They probably will grow the bottom line a little bit but it's still likely to look quite mixed - the market on the face of it is obviously seeing a few challenges."
Property for Industry was unchanged at $1.655. Ebos Group led the index, rising 1.7 per cent to $17.95, while Spark New Zealand gained 1.4 per cent to $3.895 and Fisher & Paykel Healthcare Corp advanced 1.3 per cent to $11.45.
"It's still that calm before the storm in terms of the lead up to reporting season," Lister said.
Trade Me was the worst performer, down 6.1 per cent to $4.90. The stock has sunk about 12 per cent since July 25, a day after reports emerged Amazon had settled on Melbourne as its base for an Australian launch later this year.
Deutsche Bank has downgraded it to a 'sell' rating with a price target of $4.30 and Macquarie Research lowered its recommendation to 'underperform' with a $5 price target.
"It's getting sold off reasonably solidly, basically there have been a couple of brokers reports come out over the last week raising a few concerns and risks about Amazon coming to Australia and then potentially to New Zealand," Lister said.
"There are obviously a lot of unknowns there, but it just creates a bit of uncertainty. It might mean Trade Me has to work a little bit harder to keep new threats at bay."
Outside the benchmark index, PGG Wrightson gained 1.7 per cent to 61c. The rural services company yesterday posted a 5.7 per cent gain in full-year profit, meeting its guidance, as it benefited from lower interest costs, offsetting stalled growth in revenue.
Profit rose to $46.3m in the 12 months ended June 30, from $43.8m a year earlier, it said. Sales fell to $1.13 billion from $1.18b.
"It's not a company that is front of mind for a lot of investors, but its earnings were up a little on the previous year -- it was pretty close to expectations," Lister said.
