NEW YORK, April 13 (Reuters) - U.S. stocks rose on Monday as sentiment toward key earnings reports turned positive on speculation bank results will surprise on the upside this week, while oil fell after a forecast for world oil demand was cut.
The Dow industrials, however, slipped after Boeing <BA.N> gave a gloomy profit forecast on Thursday and slashed output, reviving concerns about corporate profitability and the U.S. economy's health.
China-related news and speculation were major drivers amid light trading volume that exacerbated price moves across asset classes. Many financial centers were closed in Europe and in parts of Asia for the extended Easter holiday.
U.S. government bond prices rose as the Federal Reserve stepped up purchases of Treasury and agency debt, and the dollar and yen fell against the euro as improved appetite for risk eroded the safe-haven appeal of the U.S. and Japanese currencies.
Worries about General Motors' <GM.N> fate, along with a pullback in oil prices, also helped drag down the Dow.
But the S&P 500 rebounded on optimism that big banks will post reassuring quarterly results later this week.
"There's a general perception that the banks may have turned the corner. Whether that's true or not, I'm not sure anybody can answer that until we get some more earnings," said Mark Coffelt, chief investment officer at Empiric Funds in Austin, Texas.
"Any loans these guys make, their cost of funds is close to zero. Whatever they're lending, they're making a ton of money," Coffelt said.
After markets closed, Goldman Sachs Group Inc <GS.N> posted higher-than-expected first-quarter earnings of $1.66 billion, helped by strong trading revenue, and said it plans to raise $5 billion of common shares.
The bank posted net income of $3.39 a share, compared with analysts' average forecast of $1.49 a share, according to Reuters Estimates.
The Dow Jones industrial average <
> closed down 25.57 points, or 0.32 percent, at 8,057.81. The Standard & Poor's 500 Index <.SPX> rose 2.17 points, or 0.25 percent, at 858.73. The Nasdaq Composite Index < > added 0.77 points, or 0.05 percent, at 1,653.31.Data showed Chinese crude imports rose to their second highest level ever but crude prices fell and offset the International Energy Agency's slashing Friday of a world forecast on world oil demand.
The IEA said world oil demand would fall by 2.4 million barrels per day this year compared with 2008 as the rate of contraction in fuel consumption reached levels last seen in the early 1980s.
A report that China was considering more stimulus steps to promote growth boosted investors' optimism, leading the high-yielding Australian and New Zealand dollars to advance.
Platinum rose to a near seven-month high on fund buying and signs of recovering Chinese demand.
"The major theme today is China and the positive outlook for a recovery, with the Australian and New Zealand dollars benefiting from the theme," said Andrew Busch, global FX strategist at BMO Capital Markets in Chicago in a note to clients.
"The greenback and Japanese yen are losing value against most major currencies with market appetite for risk increasing with the recent string of positive equity moves," Busch said.
Oil fell. U.S. crude <CLc1> settled $2.19, or nearly 4.2 percent, lower at $50.05 while ICE Brent crude <LCOc1> shed $1.92 to $52.14.
Gold futures briefly rose above $900 an ounce in thin holiday trade. U.S. gold futures for June delivery <GCM9> settled up $12.50 at $895.80 an ounce in New York.
Bond prices rose as the Fed bought $7.37 billion of Treasuries, near the high end of recent purchases. It also took on $7.93 billion in agency bonds, the biggest amount to date.
Such support was enough to offset a late-day rebound in stocks, which were bolstered about hopes that bank earnings might offer some positive surprises.
"The U.S. government is the 800-pound gorilla in the bond market," said Andrew Brenner, vice president at MF Global.
The benchmark 10-year U.S. Treasury note <US10YT=RR> rose 16/32 in price to yield 2.86 percent. The 2-year U.S. Treasury note <US2YT=RR> rose 5/32 to yield 0.88 percent.
The dollar fell against a basket of major currencies, with the U.S. Dollar Index <.DXY> down 1.17 percent at 84.533.
The euro <EUR=> rose 1.44 percent at $1.3376. Against the yen, the dollar <JPY=> was down 0.15 percent at 100.07.
