"We've seen a decent step up in volatility. That alone appears to have triggered a degree of selling. There's been a lot of money in New Zealand chasing high yields and perhaps some of that money is returning to whence it came," Goodson said.
Sky TV declined 3.2 per cent to $4.58, in what Goodson described as "an extraordinary sell-off" after it reported a mixed result on August 21, with profit rising 6.4 per cent on falling subscriber numbers as new digital platforms eat into its traditional dominance of the pay television market. Sky TV shares went ex-dividend earlier this week, explaining some of a 7.5 per cent fall for the week.
"It's continuing an extraordinary sell off. It was over $6 just several weeks ago," Goodson said. "The result largely met expectations but what was concerning was the absence of subscriber growth. We're certainly seeing overseas a lot of cord cutting."
Z Energy rose 0.2 per cent to $5.85. The service station chain warned it may face millions of dollars of additional costs as the Customs Service seeks to claw back excise duties stretching over the past three decades on leftover fuel in a pipeline from the Whangarei refinery.
Outside the benchmark index, Pumpkin Patch rose 1.4 per cent to 14.2c after it announced it has appointed Dave Foster as its chief financial officer.
