Near-400-point decline turns Dow industrials negative for 2018

The Dow Jones Industrial Average tumbled on Monday, erasing its year-to-date gain, pushing the blue-chip indicator negative for 2018. The Dow declined 335 points, or 1.4%, at 24,610, for a decline in the first three months of the year of about 0.4%. Any close above 24,719.22, the average‘s close for 2017, according to FactSet data, would push it into positive territory. The S&P 500 index, meanwhile, closed 1.4% at 2,712, while the Nasdaq Composite Index wrapped 1.8% lower at 7,344. All three benchmarks ended off their lows of the session, but weighed by selling in technology shares, amid a data scandal tied to how Facebook Inc. has managed user information during the 2016 presidential campaign. The S&P 500 and the Nasdaq are both positive for the year, with the S&P 500 up 1.5% so far this year and the Nasdaq boasting a return of 6.4%.
