NEW YORK, Sept 7 (Reuters) - U.S. stocks rallied on Wednesday, reversing three days of losses on hopes the European debt crisis might ease after Germany's top court smoothed the way for Berlin's participation in bailout packages.
The S&P and Nasdaq both topped 2 percent, and all ten S&P sector indexes were higher in a broad rally.
European stocks bounced back from a two-year low after the German court rejected lawsuits aimed at blocking the country from joining in to aid Greece and other nations.
But the court said the government must get approval from a parliamentary committee, which could further slow a response. The FTSEurofirst 300 index of top European shares closed up 3 percent. [.EU] For details, see [ID:nL5E7K70Q9]
