U.S. Stocks Rise on Greece Optimism; Oil Erases Advance

U.S. stocks rose, adding to last week’s rally, amid speculation Greece will stay in the euro after polls showed voters supporting politicians who back the nation’s bailout. Commodities erased earlier gains while Treasuries were little changed.

The Standard & Poor’s 500 Index added 1.1 percent at 4 p.m. in New York, adding to last week’s 1.7 percent gain. The Stoxx Europe 600 Index climbed 0.8 percent and the MSCI Emerging Markets Index jumped 1.4 percent. The Dollar Index, a gauge of the currency against six major peers, was little changed even as the euro weakened 0.3 percent to an almost two-year low of $1.2504. Ten-year Treasury yields increased less than one basis point to 1.75 percent, erasing earlier declines. The S&P GSCI Index of commodities lost 0.5 percent.
