New Zealand shares gained as A2 Milk Co rebounded from recent selling, while Fletcher Building and Comvita fell.
The S&P/NZX 50 Index rose 37.54 points, or 0.4 per cent, to 8,590.77. Within the index, 23 stocks rose, 17 fell and 10 were unchanged. Turnover was $169 million.
A2 Milk was the best performer, up 4.1 per cent to $10.66. The milk marketer's shares slumped 13 per cent last week and a further 9.3 per cent this week after it missed expectations, prompting some analysts to reassess what have been optimistic assumptions for the company's outlook, and it dropped 2.3 per cent yesterday.
"It's continuing its recent extreme volatility, and the reason for that is there appears to have been some relatively strong shipment data from the Port of Lyttelton where a good deal of their product is shipped from. It's data that quite a few people subscribe to," said Matt Goodson, managing director at Salt Funds Management.
"The previous period was affected by strikes, so just how much should be read into that, I don't know. The stock is very volatile in both directions at the moment."
