NEW YORK, Feb 11 (Reuters) - World stocks and the dollar gained on Thursday in a zig-zag session after a deal emerged to help Greece tackle its debt woes, removing some of the uncertainty lingering about a possible sovereign default.
European shares extended the week's rally to a fourth day as stronger commodity and pharmaceutical shares outpaced a sharp decline in banks, pulled down by uncertainty over details over the rescue plan for Greece. On Wall Street, all three major indexes advanced, also buoyed by data that indicated the U.S. labor market may be healing.
European leaders agreed to provide financial aid to Greece, but details on the package, which leaked from multiple sources, were not expected until early next week when European Union finance ministers meet. For details see [
].The euro extended losses versus the U.S. dollar, falling below $1.3600, as investors expressed concern that the plan may not be enough to pull Greece out from its fiscal crisis. [
]"The confusion over the bailout is leaving traders a little nervous. It seems now that the EU has made a decision to help Greece, but just what that help entails is still a mystery," said Jimmy Yates, head of equities at CMC Markets.
The head of the Eurogroup, Jean-Claude Juncker, did say that any aid for Greece, would not be "money for nothing," saying that aid would be conditioned on "drastic measures."
Wall Street rose as the news on Greece relieved anxiety and on an improving U.S. labor market picture as first-time claims for jobless benefits fell more than expected. Copper futures rallied sharply on the jobless data and as Chinese inflation data bolstered improved economic sentiment.

"There is still some nervousness. Markets could also perhaps realize more and more that there may be a bailout but it will come at a cost and the cost is that they really have to be tough on the fiscal side," Klaus Wiener, head of research at Generali Investments, said of expectations of what an aid package for Greece may entail.
"When we look at the pillars of growth that we had over the last months, it was really fiscal spending. Now if countries have to go into reverse, that's not boding well for the growth momentum," he added.
