U.S. stocks rose, sending the Standard & Poor’s 500 Index up from a three-month low, after better-than-forecast economic data offset Greece’s struggle to form a new government as the nation planned new elections.

Equities swung between gains and losses as investors weighed better-than-estimated reports on manufacturing in the New York region and confidence among U.S. homebuilders, while concern grew about Greece leaving the euro.
