FXstreet.com (San Francisco) - The Australian dollar has come under selling pressure in thin trading after AU business confidence registered readings slightly lower than last month. AUD/USD has dipped to as low as 1.0408 and currently trades at 1.0413. The 100-hour EMA (1.0410) is now supporting price, but should the downward momentum accelerate, the 1.0400 handle (200-hr EMA) would be the first bearish target, then 1.0380. Regional shares are mixed as trading in Asia gets underway, with Japan’s Nikkei up 0.2% and Australia’s ASX down 0.8% at the time of writing.
