SINGAPORE, July 21 (Reuters) - Asian stocks rose on Wednesday as investors cheered Apple's strong earnings and on optimism that China may roll back policy tightening measures later this year, while the euro firmed ahead of euro zone's bank stress test results late in the week.
The MSCI index of Asia Pacific ex-Japan stocks <.MIAPJ0000PUS> rose 0.8 percent, led by the resources sector <.MIAPJMT00PUS>, which gained 1.6 percent on hopes that China's voracious demand for commodities would remain strong. South Korean shares <
> rose 0.6 percent, buoyed by memory chip makers such as Samsung Electronics <005930.KS> on hopes memory chip demand would stay robust after Apple <AAPL.O> posted stronger-than-expected results and gave an unusually upbeat revenue forecast after the Wall Street closing bell.Weak revenue growth reported by some other major U.S. firms over the last week had fueled fears that its economic recovery was losing momentum. [
]"Apple's strong set of results and U.S. Nasdaq index futures' <NDc1> subsequent gains, have prompted foreign buying into Seoul technology stocks," said Kim Seong-bong, a market analyst at Samsung Securities.
"Apple's earnings point to earnings growth for domestic memory chip makers, which probably supply chips to Apple," said Lim Dong-min, a market analyst at KB Investment & Securities.
Shares of Apple, maker of the iPhone and iPad, jumped more than 3 percent in after-hours trade, which could help U.S. stocks to their third straight day of gains on Wednesday.
Japan's Nikkei average <
> clawed 0.2 percent higher, but gains were limited by profit-taking amid lingering worries over the U.S. recovery.Risk-taking was boosted by reports by several investment banks, including Goldman Sachs and Morgan Stanley, that the Chinese authorities would roll back policy tightening later this year to support economic growth.
China's annual economic growth decelerated to 10.3 percent in the second quarter from 11.9 percent in the first quarter.
"Our base case is for loosening to occur in the three months starting from August but even sooner is possible," analysts at Goldman said in a report issued this week.
U.S. stocks staged a late-day rebound to end higher on Tuesday, shrugging off disappointment over some company earnings reports and a drop in U.S. housing starts, as investors bought beaten-down shares amid speculation the Federal Reserve will take steps to spur lending. [

]EURO AWAITS STRESS TESTS
In currency markets, the euro inched up against the dollar, a day after being knocked from a 10-week high above $1.3000 due to profit-taking ahead of euro zone bank stress test results due out on Friday.
The euro stood at $1.2896 <EUR=>. It rose as far as high as $1.3029 on Tuesday, its highest since May 10, and has now tested the $1.3000 level for three days in a row.
Traders said players were likely to keep taking profits in the near term on the euro's sharp rally which has taken it up more than 8 percent since it hit a 4-year low of $1.1876 in early June.
But losses in the euro are expected to be limited before the stress test results are announced, with some analysts saying the results could soothe concerns about how European banks would cope with a deterioration in the regions' economy.
Markets were also awaiting testimony from Federal Reserve Chairman Ben Bernanke to Congress later in the day (1800 GMT).
If a recent softening in a range of economic data is matched by greater unemployment, analysts say the U.S. central bank may be forced to take some form of action in coming months, even if its room to manoeuvre appears quite limited. [
