Investors "are speculating that MetroGlass will be taken out of the 50," said Rickey Ward, NZ equity manager at JBWere. "The market cap has come down and people are repositioning" ahead of the March quarter rebalance.
Fletcher dropped 1.8 per cent to $6.49 although Ward said chief executive Ross Taylor "has been talking a very credible story" about trying to ringfence losses at the company's B+I unit while completing a strategic review of the whole group. Steel & Tube declined 0.5 per cent to $2.08.
Ward said New Zealand shares also fell today in an environment "where people are a little bit more cautious." Global events including the uncertainty over Italy's elections were "weighing on risk appetite globally." The S&P/ASX 200 Index was down 1.1 per cent today.
Investors in New Zealand shares were also digesting the latest earnings season, where a number of companies had retained their guidance but that had led to some analyst downgrades given "valuations have been confirmed to be a little bit stretched at the moment," Ward said.
A2 fell 1.5 per cent to $12.56, having soared 58 per cent this year. Ward said it has continued to drift after its "extreme run" and also on news that management had been selling shares. Synlait Milk decreased 0.1 per cent to $7.49 and honey products exporter Comvita fell 1.3 per cent to $7.40.
Westpac Banking Corp declined 2 per cent to $31.95 and Australia & New Zealand Banking Group fell 1.9 per cent to $30.13, reflecting the lenders' weaker stock across the Tasman.
F&P Healthcare fell 3.3 per cent to $13.25 and Ryman Healthcare fell about 1 per cent to $10.40. Kathmandu rose 2.7 per cent to $2.28 and Z Energy rose 1.7 per cent to $7.
Marsden Maritime Holdings was unchanged at $5.60 after chief executive Graham Wallace said he will leave the company at the end of this month.
