SHANGHAI, April 24 (Reuters) - Equity markets in Asia rose on Wednesday morning after upbeat earnings helped the Nasdaq and S&P 500 indexes reach record closing highs on Wall Street overnight, while oil retreated from its near six-month highs.
MSCI's broadest index of Asia-Pacific shares outside Japan was up 0.1 percent in early trade in Asia. The gains followed a strong performance on Wall Street, driven by robust results from Coca-Cola, Twitter, United Technologies and Lockheed Martin.
The Dow Jones Industrial Average rose 0.52 percent to 26,647.97, the S&P 500 gained 0.91 percent to 2,934.31 and the Nasdaq Composite added 1.35 percent to 8,123.25.
On Wednesday morning, S&P 500 e-mini stock futures were up 0.03 percent at 2,938.75, just short of a record high of 2,944.75 on October 3.
Australian shares gained 0.6 percent, while Japan's Nikkei stock index was 0.3 percent higher. Seoul's Kospi was up 0.1 percent.
Analyst said that alongside better-than-feared corporate earnings, a more supportive policy environment is helping to boost risk appetites.
"The Fed has been joined in its dovish tilt by major central banks across the globe ... the tilt globally reflects genuine concern not to allow individual countries and the globe to tip into recession. That risk has receded," Greg McKenna, strategist at McKenna Macro in Australia, said in a note to clients.
Equity market gains had been bolstered on Tuesday by rising energy shares after Brent crude, the global benchmark, hit its highest level since Nov. 1.
Oil prices had surged after the United States ended six months of waivers that allowed Iran's eight biggest buyers, most of them in Asia, to continue importing limited volumes of Iranian oil.
Gulf OPEC members said that rather than offset any shortfall resulting from the U.S. decision on waivers, they would raise output only if there was demand.
But early on Wednesday, Brent had given up some gains, trading down 0.54 percent at $74.11 per barrel. U.S. crude dipped 0.54 to $65.94 a barrel.
U.S. Treasury yields ticked lower. Benchmark 10-year Treasury notes yielded 2.5686 percent compared with a U.S. close of 2.57 percent on Tuesday, while the two-year yield, slipped to 2.3516 percent, compared with a U.S. close of 2.364 percent.
The U.S. dollar index, which tracks the greenback against a basket of six major rivals, eased 0.03 percent to 97.606. The dollar was down 0.04 percent against the yen to 111.82.
The euro edged 0.08 percent lower to buy $1.1216.
Spot gold fell about 0.1 percent to $1,271.07 per ounce. (Reporting by Andrew Galbraith; Editing by Richard Borsuk)
