Shares in accounting software firm Xero jumped 6.73 per cent to $21.90, with Lister saying the company had been performing well of late.
"As far as Xero goes, it's had a very good string of gains lately," Lister said. "It got as low as around the $14 mark at one point and so it's been a very good performer in the last few months."
"It's always been a good company but it polarises people in terms of the investment view that people have of it. It's a high risk, high return stock that is difficult to value and difficult to pinpoint what its worth and its been much more volatile than just about everything else over the last few years," he said.
Ryman Healthcare rose 3.3 percent to $7.90, adding to Friday's 2.6 percent gain after the country's biggest retirement village operator posted a 23 percent increase in first-half profit.
"Ryman's up on the back of a better than expected six-month report on Friday," Williamson said. "The company continues to grow earnings around 15 percent per annum, and it's probably time that share price moved up."
Metro Performance Glass climbed 2.7 percent to $1.54 after the country's biggest glass processor reported first-half profit in line with guidance, and affirmed its forecast for annual earnings.

Private training institution Intueri Education Group plunged 31 percent after it said the Tertiary Education Commission was reviewing funding at two of its schools, which could cut annual earnings by up to $5 million.
"There's quite a bit of uncertainty building up in that company," Williamson said. "It's a bit of a disaster for shareholders."
Evolve Education Group rose 3.1 percent to 99 cents after the early childhood education operator said annual earnings were in line with expectations after posting a first-half profit of $8.4 million, and that it had enough headroom for more acquisitions.
