S&P 500 Pares Gain; Oil Plunges, 30-Year Yields Below 3%

A rebound in U.S. stocks faded late in the session as energy shares led losses amid a slide in oil, offsetting rallies in small-caps and airlines. Yields on 30-year Treasuries fell below 3 percent for the first time since 2013.

The Standard & Poor’s 500 Index rose 0.2 percent to 1,877.70 at 4 p.m. in New York, after erasing a rally of as much as 1.3 percent. Energy shares in the S&P 500 entered a bear market as Brent crude plunged 4.2 percent to an almost four-year low. The Dow Jones Industrial Average fell less than 0.1 percent, while the Russell 2000 Index surged 1.2 percent. Treasury 30-year yields slid 5 basis points to 2.96 percent amid bets the Federal Reserve will push back the timing on raising interest rates. The dollar rose against most of its peers.
