Nov 8 (Reuters) - Australian shares closed higher on Thursday boosted by financial stocks, riding a wave of relief on Wall Street which rallied as U.S. midterm election results came in largely as expected. MKTS/GLOB
The S&P/ASX 200 index .AXJO closed 0.53 percent or 31.3 points up at 5,928.200, near a three-week high.
Gains were driven by financial stocks .AXFJ which rose 1 percent. Top gainers were Commonwealth Bank of Australia CBA.AX and Australia and New Zealand Banking Group Ltd ANZ.AX which closed 1.8 percent and 2 percent higher, respectively.
Australia's banking regulator said on Thursday it wants to raise the amount of spare cash banks carry to withstand any future financial shock, adding to pressure on a sector already embarrassed by a public inquiry that exposed widespread misconduct in the financial industry. Rooney, director of equity sales at Argonaut, said the higher cash requirement had been expected and was already priced into banks' share prices.
Aussie healthcare sector .AXHJ , which has high exposure to U.S. markets, rose 1.2 percent with index heavyweight CSL Ltd CSL.AX gaining 1.3 percent while Cochlear Ltd COH.AX edged up 1.1 percent.
Noting U.S. President Donald Trump's criticism of the U.S. healthcare sector and pharmaceutical companies' pricing, Rooney expected better export prospects for healthcare and pharmaceutical companies, as U.S. President Donald Trump's criticism of their pricing appeared less of a risk now that his Republicans had lost control of the House.
"It probably takes a little bit of pressure off the healthcare sector. Most of our pharmaceutical companies look to export into their market, I think that's the main reason we're up," Rooney said.
Gains in Wall Street were led by healthcare stocks, among others.
Metals and mining stocks .AXMM were marginally lower, capping gains on the benchmark, as weak steel and iron prices weighed following Beijing's move to relax curbs on production during winter. IRONORE/
New Zealand's benchmark S&P/NZX 50 index .NZ50 ended 0.47 percent or 41.22 points to finish the session at 8,896.01, its highest close in three weeks.
Dairy firm a2 Milk Company Ltd A2M.AX closed 1.6 percent higher.
