* Yen's slide halts just before 100 to dollar
* BOJ action keeps global bond yields near lows
* Benign China inflation data boosts stock and commodity sentiment
* Stocks reflect earnings expectations and China data
NEW YORK, April 9 (Reuters) - Stocks around the world rose on Tuesday, helped by positive Chinese economic data that supported expectations of better corporate earnings, while the yen snapped a three-day decline against the U.S. dollar.
A report showing benign Chinese inflation raised hopes for a more accommodative monetary policy from China and also gave a lift to commodities, including copper and oil.
China's annual consumer inflation cooled in March as food prices eased from nine-month highs and producer price deflation deepened, the data showed, leaving policymakers room to keep monetary conditions easy and nurture a nascent recovery.
That left stocks the key focus in financial markets as the yen struggled late in the global trading day after earlier reversing its recent decline against both the dollar and euro.
A significant driver of the U.S. stock rally has been the extraordinary stimulus measures from the Federal Reserve, and investors will be looking at company forecasts to gauge whether the fundamentals are strong enough to keep stocks climbing higher.
"The economy is still moving in the right direction, just less speedily than we want to see," said Andrew Wilkinson, chief economic strategist at Miller Tabak & Co in New York.
The Dow Jones industrial average was up 92.61 points, or 0.63 percent, at 14,706.09. The Standard & Poor's 500 Index was up 9.42 points, or 0.60 percent, at 1,572.49. The Nasdaq Composite Index was up 22.63 points, or 0.70 percent, at 3,244.88.
Alcoa Inc, the first Dow component to release results, reported a higher quarterly profit but lower-than-expected revenue after the bell on Monday. Shares of the largest U.S. aluminum producer fell 0.1 percent to $8.38. .
Weak demand in Europe was a key drag on Alcoa's results, and also hurt March sales at Volkswagen with shares in the German carmaker dropping 2.6 percent.
Europe's FTSE Eurofirst 300 index finished up just 0.05 percent with concerns about weak first-quarter earnings outweighing prospects for continued strong metals demand from China.
But MSCI's world equity index, which tracks share prices in 45 countries, was up 0.6 percent.
The yen remained the central trade in currency markets.
The Japanese currency weakened to 99.66 to the dollar, according to Reuters data, the greenback's strongest level against the yen since May 2009, before the sell-off in the yen stalled and sent the dollar back to 98.58 yen.
Even as it happened, analysts were suggesting the yen's advance would be temporary and it was only time before the Japanese unit would again weaken and the dollar sail past the 100-yen mark.
"Given the breadth of yen bearishness, any reprieve would likely encourage investors to re-establish short yen positions at more favorable exchange rates," said Joe Manimbo, senior market analyst at Western Union Business Solutions in Washington, D.C.
Late in the New York session on Tuesday, the Japanese currency was down 0.1 percent at 99.23 yen.
The U.S. currency has still gained around 7 percent against the yen since the Bank of Japan unveiled a massive stimulus program Thursday involving large purchases of long-term Japanese government bonds.
The BOJ's bold measures have had a major impact on the world's main debt markets, sending Japanese government yields down sharply and spurring a search for higher-yielding assets, which has caused yields to fall on U.S. and euro zone bonds.
"Markets are increasingly focused on the notion that larger JGB purchases, at longer maturities, by the BOJ could push Japanese domestic long-term investors elsewhere," said Vassili Serebriakov, strategist at BNP Paribas in London.
However, yields on highly rated euro zone bonds moved up from record lows as investors began to position for fresh government debt auctions.
German 10-year bond yields were higher at 1.277 percent, having hit 1.2 percent on Friday, their lowest level since mid-2012 before European Central Bank President Mario Draghi promised to do whatever it took to save the euro. The euro rose against the yen for a fourth day, at one point, climbing to its highest since January 2010.
U.S. government debt prices were little changed on Tuesday.
Benchmark 10-year Treasury note yields were at 1.75 percent.
The Chinese data underpinned demand for copper, which climbed to a two-week high of $7,645.25 a tonne on the London Metal Exchange before paring slightly to trade at $7,628.75 a tonne, up 2.4 percent.
Crude oil also gained on the Chinese data, and a stalemate in talks between Iran and Western nations over its nuclear program and rising tensions on the Korean peninsula also supported prices.
Brent rose 1.6 percent to $106.37. U.S. oil futures rose 0.9 percent to $94.24 a barrel and
