LONDON, April 20 (Reuters) - Equities rose on Tuesday, helped by buoyant corporate earnings and growing optimism about the global economic outlook, which weighed on the U.S. dollar as risk-taking sentiment strengthened.
Above-forecast earnings from Goldman Sachs Group Inc <GS.N>, which also said it was encouraged by growth prospects for the economy, deflected attention away from the U.S. Securities and Exchange Commission's fraud charge against it. [
]European shares gained more than 1 percent, while U.S. futures pointed to a stronger open on Wall Street, buoyed by Citigroup posting its best results since 2007 on Monday and an upbeat profit outlook from German carmaker Daimler <DAIGn.DE>. The FTSEurofirst 300 index <
> of major European shares rose 1.3 percent, while U.S. stock futures <SPc1> <DJc1> <NDc1> were up by 0.2-0.4 percent."Results have driven shares higher. After a couple of down days Citi came out with stellar results and people started buying again," said Mic Mills, senior trader at ETX Capital.
"Investors are a bit concerned that equities are a little overbought, but on the other hand they don't want to be caught on the wrong side of a rally."
The MSCI world equity index <.MIWD00000PUS> gained 0.5 percent and emerging stocks <.MSCIEF> were up 1 percent.
Oil <CLc1> jumped more than $1 per barrel to $82.52 on firmer risk appetite and as some European flights resumed after a threat from spewing volcanic ash in Iceland receded.
A fall in the dollar and a rise in other commodity prices lifted gold prices <XAU=> back above $1,140 an ounce.
EURO GAINS; GREECE CONCERNS REMAIN
A strong rebound in German analyst and investor sentiment in the latest ZEW survey pushed the euro higher, causing it to erase earlier falls. [
]The euro <EUR=> rose 0.1 percent to $1.3502, while strengthening risk demand weighed on the safe-haven U.S. dollar <.DXY>, which fell 0.2 percent against a basket of currencies.
"April's sharp rise in German ZEW investor sentiment provides some hope that the recovery has not ground to a complete halt after the economy's poor start to the year," said Ben May at Capital Economics.
Concerns about Greece's parlous fiscal situation lingered, however, limiting the single currency's gains and causing the spread between Greek and German 10-year yields to widen to a fresh euro lifetime high. [
]German Bund futures <FGBLc1> fell 27 ticks to 123.47, dented by the rise in equities.
The Wall Street Journal reported that European Central Bank Governing Council member Axel Weber said Greece may require assistance of up to 80 billion euros. [
]Greece has yet to ask for activation of the EU/IMF aid safety net agreed earlier this month, estimated at 45 billion euros in the first year. [
