July 4 (Reuters) - Australian shares fell on Wednesday as financials reversed their gains from the previous session, while materials stocks continued their decline on weaker commodity prices.
The S&P/ASX 200 index was down 0.4 percent, or 23.5 points to 6,189.1 by 0150 GMT.
May retail sales came in slightly higher than expected at 0.4 percent, but were lower than the revised value for April.
“The retail sector has been under sustained pressure for many years so any surprise on retail sales does have potential market implications,” said Michael McCarthy, chief strategist at CMC Markets and Stockbroking.
The benchmark climbed 0.5 percent on Tuesday.
Financial stocks led the losses after rising 0.9 percent on Tuesday, with the main financial index down 0.6 percent as investors took profits.
Platinum Investment Management, which has investments in China, was the top percentage loser on the benchmark, sliding as much as 9.9 percent to a near 11-month low, as trade war concerns weakened Chinese asset prices.
“The market is really getting into the trade war fears. Chinese moves to support the yuan showed that any move by the United States in the trade war will drive the yuan and Chinese equities even lower,” said Mathan Somasundaram, a Blue Ocean Equities market portfolio strategist.
Australia and New Zealand Banking bucked the broader trend while the other “Big Four” banks traded in a range of 0.2 percent to 0.6 percent lower.
