"They've seen their fair share of selling recently [due to Australia's Royal Commission into misconduct in that country's financial services sector]. Today's more of a bounce than anything to get too excited about if you're an owner of the big four banks," Davies said.
Westpac shares are down 11 per cent this year, while ANZ's have dropped 6 per cent.
Pushpay Holdings gained 1.2 per cent to $4.18. The mobile payment app company completed a $100m bookbuild yesterday, letting executive director Eliot Crowther exit the firm he co-founded.
The bookbuild was oversubscribed, with bids subject to scaling, and got offers from 19 institutional investors across New Zealand, Australia and the US, Pushpay said.
The stock led the index lower yesterday, down 5.5 per cent to $4.13 after the shares were lifted from the trading halt during the bookbuild.
"It has recovered, and it's at a decent premium to the selldown price, they'll be pretty pleased with how that has played out so far," Davies said.
"By the sounds of things, they have good institutional investors on board and it wasn't a huge discount, indicating there's good demand there."
Synlait Milk rose 0.9 per cent to $10.74. It will develop its second nutritional powder manufacturing factory for an estimated initial capital investment of $250m at its new Pokeno site in Waikato, which will be commissioned for the 2019/20 season as it aims to keep up with growing demand for infant formula product.
"Forecast customer demand" prompted Synlait to boost the capacity for its first nutritional spray dryer at Pokeno to 45,000 metric tonnes, up from its initial plan for 40,000 tonnes, the company said in a statement.
Sky Network Television was the worst performer, down 4.5 per cent to $2.33. Davies said there was a really large bid-ask spread on the stock, about $2.34 on the bid side and sellers at $2.42, and lots of little trades today.
