NZX 50 Index creeps up 0.1 per cent THE New Zealand sharemarket has edged higher, with retirement village stocks back in favour. THE NZX 50 Index rose 6.232 points, or 0.1 per cent, to 5409.229 on Monday. Within the index, 22 stocks rose, 19 fell and nine were unchanged. Turnover was $88 million. Retirement village operators have been underperforming the market this year, but Ryman Healthcare advanced 1.3 per cent to $7.80 on Monday, Summerset rose 1.1 per cent to $2.77 and Metlifecare gained 0.5 per cent to $4.39. "They had shown weakness for a while now but I think a few investors are thinking the sell down has been a bit overdone," Hamilton Hindin Greene director Grant Williamson said. Investors are finding it more and more difficult to find value on the market, so although I'm not expecting any large corrections I do think we might start to see a little bit of more profit taking come into the market, which may just limit the upside in the short-term. Spark New Zealand fell from a seven-year high, declining 0.2 per cent to $3.265 and Z Energy fell 1.4 per cent from a record close on Friday to $4.33. Oceana Gold Corp led the benchmark index higher, climbing 7.1 per cent to $2.42. Auckland International Airport rose 1.8 per cent to $4.06 and Steel & Tube Holdings increased one per cent to $3. Pacific Edge was the worst performer on the index, declining 3.7 per cent to 79 cents.
