* Shanghai composite index leaps 7 pct, pulling Asia up
* MSCI world stocks index hits 23-month low overnight
* Oil, metals edge up as U.S. dollar struggles (Updates prices, adds European outlook)

HONG KONG, Aug 20 (Reuters) - Most Asian stock markets edged up on Wednesday, recovering from a two-year low as Chinese shares surged on hopes Beijing would introduce a stimulus package to jumpstart growth, though many analysts said it was a long shot.
European equities were expected to open slightly higher, according to financial bookmakers, with energy stocks seen benefiting from a rise in oil prices.
The dollar struggled as crude oil crept above $115 a barrel and gold prices rose, taking some of the steam out of the U.S. currency's recent surge to a seven-month high.
On Tuesday, the MSCI all-country world equities index <.MIWD0000PUS> slid to the lowest since September 2006. Investors are increasingly sceptical about corporate earnings for 2009, given the mixed results so far in 2008 and constant reminders about instability in the financial sector.
However, most Asian indexes turned higher as cheap valuations proved irresistible, especially with markets rife with chatter about fiscal stimulus in China.
"Bargain hunters have returned to the market on talks that a rescue package is on the way," said Francis Lun, general manager from Fulbright Securities in Hong Kong. "We are all waiting for a miracle," Lun added.

Despite the sudden turnaround in Asian stocks, apprehension about the earnings outlook remained, especially after the Bank of Japan on Tuesday described the world's second-largest economy as "sluggish" -- a term it has not used since the Asian financial crisis a decade ago.
Donald Straszheim, vice chairman of Roth Capital Partners in Los Angeles and a long-time China analyst, said the Chinese stock market, the worst performer this year, will continue to fall because of the toxic concoction of slowing growth and high inflation.
He expects earnings to rise 15 percent in China this year, down from the 30 percent to 45 percent pace enjoyed by most sectors in 2006 and 2007.
"Shanghai has proven to be a very emotional market, and is likely to stay that way," Straszheim said in a note to clients.
Stephen Green, head of China research with Standard Chartered Bank, said that given economic growth is still expected to stay above 8 percent this year and next, it was too early for the government to squeeze its budget to boost growth.
Rather, Beijing should consider relaxing loan quotas to stimulate bank lending to support growth, he said.
"It is too early for a fiscal stimulus package, and we should be responsible about calling for one," he said in a note. "There is still room for monetary policy before we try fiscal policy."
Though slowing export demand in China has pulled down overall growth this year, authorities there continue to push the country's economy to depend less on foreign trade and more on domestic consumption, which has been buoyant despite high inflation, market downturns and natural disasters.
After weeks of liquidation of positions in the metals markets, which have helped to push up the U.S. dollar, investors slowed down to survey the scene.
The euro slipped 0.15 percent to $1.4761 <EUR=>, but was up from a six-month low around $1.4630 hit on Tuesday. The dollar rose 0.3 percent to 109.93 yen <JPY=>, though it was struggling to test a seven-month high of 110.67 yen reached last week.
Metals markets were relatively quiet compared with the last few days. Gold rose 0.4 percent in the spot market to $816 an ounce <XAU=>, spending only a few days trading below $800.
The September U.S. light crude contract <CLc1> rose 40 cents to $114.95 a barrel, gravitating around the $115 mark throughout the session.
