The New Zealand stock market faced major indexation changes today in the way markets' operator NZX Limited calculated the positioning of stocks, with Telecom and Fletcher Building's representation being increased while Contact Energy and pay TV operator Sky Network Television would be reduced.
The NZX50 index was up 0.9 per cent or 30.98 points to 3447.07. Within the index, 30 stocks rose, 12 fell and eight were unchanged.
Tyndall Investment Management domestic equities manager Rickey Ward said a lot of investors would have been waiting in the wings for the amendments to the NZX to come through.
"The NZX50 and portfolio index has gone through an amendment in the methodology of how they calculate the indices and that gets implemented today. There are a number of stocks that are impacted as a result of those changes," Ward said.
"The main two are Contact Energy and Sky TV which is why there has been a bit of pressure on them in the last couple of days. These changes have been very well flagged so people are positioning themselves now for it. There has been reasonable volume through the market today but as a general rule outside of those index changes people are probably sitting on the sidelines waiting to see what will happen with the Greek elections."
Sky TV was down 0.8 per cent to $4.90 while Contact Energy rose 1.9 per cent to $4.78. Telecom rose 3.1 per cent to $2.48 and Fletcher Building rose 2.4 per cent to $2.12.
