Oil drop stymies Dow's march to 20,000; techs send Nasdaq to record

Declines in financial and energy companies weighed on Wall Street on Monday, stalling the Dow's pursuit of 20,000, while the Nasdaq hit a record intraday high on gains in technology stocks and a string of deals in the health sector. Two-thirds of the 30 Dow components were lower, with Exxon Mobil's 2.1 percent decline weighing the most, followed by a 1.3 percent drop in Chevron . The declines meant the Dow stayed shy of the psychologically significant 20,000 mark.
