Asian shares ease after Fed-led rally TOKYO (Reuters) - Asian shares retreated from four-month highs on Tuesday while gold and copper eased, as markets paused from sharp gains inspired by the Federal Reserve's aggressive stimulus and turned instead to concerns about the growth slowdown in China. MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS fell 0.5 percent as investors calculated the impact on growth from the Fed's additional easing while taking profits from its loftiest point since May 3 touched on Monday. The pan-Asian index soared some 3 percent since the Fed launched a third round of bond buying known as quantitative easing (QE3) on Thursday, which spurred a broad based jump in riskier assets. European equities were seen edging down after slipping from 14-month highs on Monday, while a 0.1 percent rise in U.S. stock futures suggested a steady Wall Street open. Financial spreadbetters called London's FTSE 100 .FTSE, Paris's CAC-40 .FCHI and Frankfurt's DAX .GDAXI to open down 0.1 percent. .L .EU .N Commodity-reliant Australian shares .AXJO eased 0.1 percent while Shanghai shares .SSEC slid 0.7 percent. "Investors are really in defensive mode today, and probably will stay that way until Thursday, when we get the fresh read on manufacturing out from China," said Juliana Roadley, a market analyst at Commonwealth Securities, referring to the HSBC flash purchasing managers' index (PMI). Amid slackening demand from top customer China, Australia on Tuesday revised down minerals and energy export revenues by 9 percent to A$190 billion ($200 billion) in the year to June 30, 2013. It also cut its revenue forecasts for iron ore by a fifth. Chinese shares were pulled down by commodities-related stocks following steep overnight losses in physical markets. "It's definitely making some people wonder if hedge funds were unwinding their positions this quickly after the QE3 announcement, but it's a bit too early to say that it reflects anything about their longer term view on the Fed's action," said Edward Huang, equity strategist with Haitong International Securities. The Nikkei stock average .N225 gave up early gains to edge down 0.1 percent, caught between a supportive weaker yen and concerns over firms having large exposure to China, where anti-Japan protests were escalating as tensions mounted over a territorial dispute between Asia's two biggest economies. .T Masayuki Doshida, senior market analyst at Rakuten Securities, said sentiment was also underpinned by expectations that the Bank of Japan will follow the Fed with its own stimulus measures, to stem the yen's appreciation after the Fed's move last week. The BOJ ends its two-day policy meeting on Wednesday. The yen traded at 78.62 to the dollar, off a one-week low of 78.93 touched on Monday. The Fed's move undermined the dollar and lifted the yen to a seven-month high of 77.13 on Thursday. The dollar index .DXY measured against a basket of key currencies stayed near Friday's 6-1/2 month low of 78.601. The euro eased 0.1 percent to $1.3096, slipping from a 4-1/2 month high of $1.31729 hit on Monday. Oil pared earlier gains to trade steady, with U.S. crude oil futures at $96.62 a barrel and Brent trading at $113.72. Copper was down 0.1 percent at $8,293.25 a metric ton. Spot gold fell 0.3 percent to $1,754.99 an ounce, below a 6-1/2-month high of $1,777.51 hit on Friday. <GOL/> "Gold has been rising steadily so it's natural that profit taking takes place in the short term," said Yuichi Ikemizu, branch manager for Standard Bank in Tokyo. But over the longer term, the Fed's accommodative stance will stoke inflation fears and undervalue the dollar, bolstering gold's appeal as a hedge against these factors, he said, adding that he expected firm support at $1,730, with markets likely to test last year's peak above $1,900 before the end of the year. Asian credit markets were a touch softer, with the spread on the iTraxx Asia ex-Japan investment-grade index widening by 2 basis points but still near a 14-month low.
