U.S. stocks rose to record highs, Treasuries tumbled and the dollar weakened against all of its G-10 peers in the first official day of trading in 2018.
Technology shares led the rally and analyst upgrades fueled gains in consumer-discretionary companies. The NASDAQ 100 Index climbed 1.8 percent, the biggest gain since Oct. 27. The NASDAQ Composite closed above 7,000 for the first time, while the Standard & Poor’s 500 Index also finished at an all-time high. European stocks started the year in the red, failing to capitalize on a positive Asian session as the strength of the region’s common currency weighed on exporters.
