The bond rally resumed Tuesday, driving yields on benchmark 10-year U.S. notes to their lowest level since summer and lifting technology shares on an otherwise downbeat day for stocks. 

The technology-heavy Nasdaq Composite added 0.3%. In the S&P 500, technology and consumer-discretionary shares failed to offset declines in utilities, energy, materials and real-estate stocks, and the broad index shed less than 0.1%. The Dow Jones Industrial Average fell 0.2%, or about 80 points.
