Pepsi, oil drive S&P 500 to four-month high

U.S. stocks rose on Tuesday, with the S&P 500 hitting a four-month high, as energy companies got a lift from firming oil prices and strong results from PepsiCo (NASDAQ:PEP) signaled a flying start to the second-quarter earnings season. PepsiCo's shares surged 3.7 percent and were poised for their biggest one-day jump in nearly seven years after the company's second-quarter results topped estimates on strong sales of snacks. The company also reaffirmed its full-year forecast amid signs of a gradual recovery in its soda business. PepsiCo's surge helped drive a 0.66 percent gain in the consumer staples index, the most among the 11 major S&P sectors. Rival Coca-Cola rose nearly 1 percent.
