Fear of missing out on the recovery has led investors to buy into stocks that have lagged behind in an attempt to join the last of the bounce back.
Greg Smith, head of research at Fat Prophets, said some investors had been building up liquidity while waiting for a second market correction before buying in.
"There is probably a little bit of FOMO coming through now," he said.
"A lot of deleveraging took place in March and there will be many in the market who have been waiting for the next leg back down, which hasn't happened."
With the outlook seemingly stabilising, some investors may have lost patience and bought into the market before it climbs any higher.
Last week the NZX50 rose 2.1 per cent and has gained 7.6 per cent over the last 12 months. The benchmark now sits less than 9 per cent below its February record.
Stocks that have lagged behind the recovery found support on the market today.
Tourism Holdings led the market higher, rising 11.9 per cent to $1.97 and paring its fall year to date to 43.5 per cent.
Smith said the market had been responding favourably to the restructuring which is underway and received an extra boost from the news the company had sold out of campervans over Queen's Birthday weekend.
Gentrack rose 11.9 per cent to $1.60 as investors continued to process its half-year report, released on Friday. The company noted a hit to earnings but said they were expected to improve in the second half of the year. Investors with a new-found appetite for risk were happy to take that bet.
Vista Group International climbed 9.3 per cent to $1.64, still just half what it was in February. Smith said they haven't had the same scale of recovery that others have and were seeing some catch up.
SkyCity Entertainment Group increased 7.4 per cent to $2.62, Air New Zealand rose 2.2 per cent to $1.40 and Auckland International Airport advanced 1.5 per cent to $6.60 — all stocks that were hit hard by the shutdown.
Refining NZ was the weakest performer in May, falling 23.9 per cent. Today the stock clawed back some of those losses, rising 2.3 per cent to 73 cents.
Synlait Milk jumped 9.2 per cent to $7.10, bouncing straight back from an aggressive decline on Friday. A2 Milk Company fell 1.6 per cent to $18.70.
Ryman Healthcare increased 9.5 per cent to $13.25, Metlifecare rose 3.3 per cent to $4.33, Summerset Holdings advanced 2.5 per cent to $6.15 and Oceania Healthcare gained 1.1 per cent at 90 cents. Each of these retirement operators are sitting approximately 30 per cent lower this year.
Westpac Banking Corp posted the day's biggest loss, falling 2.1 per cent to $18.60.
