Among the Dow components that reported early Tuesday, chemical and bioscience company DuPont reported a sharp drop in income on weakness in its electronics, communications and other businesses, but the results still beat analysts' forecasts and DuPont's stock rose 77 cents, or 1.6 percent, to $47.76.
Johnson & Johnson said higher sales helped boost its profit from a year ago, when results were weighed down by a slew of one-time charges. However, the company's 2013 profit forecast fell short of analysts' estimates. J&J dropped 44 cents to $72.79.
Verizon Communications Inc. rose modestly after the country's biggest wireless carrier said it activated a record number of new devices on contract-based plans in the fourth quarter. Verizon's net loss widened on restructuring and pension costs and expenses related to the cleanup from Superstorm Sandy. Its stock rose 41 cents, or 1 percent, to $42.95.
A fourth member of the Dow 30, property and casualty insurer Travelers Cos., led the Dow higher after it said core income categories like investments and premiums written rose in the fourth quarter. Net income fell because of claims filed in the wake of Superstorm Sandy. The stock shot up $2.01, or 2.6 percent, to $78.32, after hitting an all-time closing high of $76.31 on Friday.
The market was closed on Monday for the Martin Luther King Jr. holiday.
Yet another company hit by Superstorm Sandy was Delta Air Lines, which said its fourth-quarter profit was nearly wiped out after it was forced to cancel more than 20,000 flights. The storm hit Delta harder than other airlines because it slowed operations at Delta's new oil refinery near Philadelphia. Delta fell rose 50 cents to $14.11.
Tech behemoths IBM and Google are set to announce their earnings results after the market closes. Tech companies' results are being watched closely because many of them have warned about a weak fourth quarter. Apple reports after the closing bell Wednesday.
Railroads CSX and Norfolk Southern also announce after the close. Rail companies are seen as a bellwether for the broader economy because their results track the demand for transportation of materials used in manufacturing and goods sold to consumers and businesses.
