Davies said a number of today's leaders had faced the biggest falls earlier in the year.
Vista led the market higher jumping 20.7 per cent to $1.40, Air New Zealand advanced 13.5 per cent to $1.18 and Kathmandu increased 11.6 per cent to 77 cents.
Davies said news that Norges Bank Investment Management, which manages Norway's pension fund, had bought a 5 per cent stake in Kathmandu may have also supported investor confidence.
Refining NZ climbed 15.1 per cent to 99 cents following a strategic review to ensure the long-term viability of the business. The review includes whether or not to break up its operations or move to a fuel import model.
Davies said that investors were likely reassured by the refinery making early moves to protect the long-term outlook.
"In this market investors just want to know what each company is doing and sometimes just an update on that is enough to give people enough confidence to start buying again," he said.
A2 Milk rose 4 per cent to an all-time high of $19.10 as it benefitted from weakness in the New Zealand dollar and healthy demand for its products.
"They've ridden out the sell-off sentiment and then some, continuing to reward patient investors," Davies said.
