"One of two things will happen: we'll hear nothing until August, and that will be a good sign. Or, we could get an update before then, because what happens is 90 per cent of the people that spin down do it in the first six months. We just don't know, that's the problem and that's why the stock just wishes-washes around on quite a low volume," Price said.
Genesis Energy dropped 3.4 per cent to $2.305, Fonterra Shareholders' Fund fell 3.2 per cent to $5.71, and Mainfreight declined 2.8 per cent to $24.00.
Fletcher Building dropped 0.4 per cent to $5.76, the lowest it has closed since March 2009. Price said there were concerns about the potential for the stock to fall out of the MSCI New Zealand Index at its next rebalancing, to be replaced by A2 Milk Co. A2 was unchanged today at $12.92.
Kathmandu Holdings was the best performer, up 2.9 per cent to $2.50, while Auckland International Airport gained 1.9 per cent to $6.36 and New Zealand Refining Co rose 1.7 per cent to $2.37.
Synlait Milk gained 1.5 per cent to $9.08. It will spend about $18m to double production of lactoferrin at its Dunsandel plant after securing a multi-year agreement to supply the high-value milk protein to an unnamed customer.
The dairy company said a demand and supply imbalance "is driving global strengthening of lactoferrin prices and demand is notably driven from increasing use of lactoferrin in infant formula, particularly in China." It expects to complete the expansion by October.
Outside the benchmark index, Scott Technology gained 4.5 per cent to $3.50. It boosted first-half profit 26 per cent to $3.1m as demand for the Dunedin-based firm's automation and robotics systems saw it operating near full capacity.
Revenue climbed 19 per cent to $67.5m, helped by international demand for its Bladestop bandsaw safety technology, and completion of the company's first system design and build in China. Earnings before interest, tax, depreciation and amortisation climbed 25 per cent to $6.4m, with operating margins widening to 9.5 per cent from 9 per cent a year earlier.
