S&P 500 ends at seven-month high after Yellen comments

The S&P energy index rose 2 percent, leading gains in the benchmark S&P 500. Yellen's remarks, which were likely her last public comments before a policy meeting next week, followed Friday's dismal monthly jobs report, which raised concerns over the ability of the economy to absorb a rate hike as early as June. In terms of rate hike, he said, "we're not talking about June or July but maybe later this year" now.
