"There's no particular reason, turnovers this year in equities have been somewhat light," Goodson said. "The other issue is that they do particularly well out of IPOs, they haven't been thick on the ground whereas their debt market has been a bit more active. It may be a repricing up towards the multiples of its peers overseas, though sometimes you read too much into moves on fairly small volumes."
Westpac Banking Corp rose 1.5 per cent to $33, Auckland International Airport gained 1.5 per cent to $6.88, and Vital Healthcare Property Trust advanced 1.4 per cent to $2.22.
Ryman Healthcare rose 0.4 per cent to $9.03, a high since October 2016. The stock has soared 8.3 per cent with uninterrupted gains since last Wednesday.
"It's been the subject of a quite remarkable surge over the past couple of days, seemingly out of nowhere, from one or maybe several large buyers seeking stock in the name," Goodson said. "The interesting thing is the rest of the sector - Metlifecare and Summerset - haven't really participated at all. Certainly, the housing data hasn't been particularly improving, which is something Ryman has clearly leveraged. That has been a real talking point in the market today. It's just trading flows driving the move, but a very unusual move in such a large-cap name."
Fellow retirement village operators Metlifecare rose 1.3 per cent to $5.41 while Summerset gained 1.3 per cent to $4.76.
Vista Group International was the worst performer, dropping 1.7 per cent to $5.90, while Arvida Group fell 1.5 per cent to $1.29.
Outside the benchmark index, Pushpay gained 6.1 per cent to $1.75 following the close of a $25 million bookbuild where they were sold at $1.51, an 8.5 per cent discount. The company yesterday also raised its annualised committed monthly revenue (ACMR) target to US$100m (NZ$137m), announced plans to list in the US within the next 36 months, and gave guidance of US$70m in revenue for the 2018 financial year, more than double 2017's US$34m.
