U.S. stocks wavered between small gains and losses Tuesday as big companies reported their fourth-quarter financial results.
The Dow Jones industrial average rose 19 points to 13,669 as of 12:10 p.m. Eastern time. The Standard & Poor's 500 index rose a fraction to 1,486. The Nasdaq composite average dropped seven to 3,127.
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.

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.
Some homebuilder stocks fell after the National Association of Homebuilders said sales of previously occupied homes dipped to an annual pace of 4.94 million from 4.99 million in November. November's figure was revised lower, but was still the highest in three years.
PulteGroup Inc. lost 17 cents to $20.32. D.R. Horton Inc. lost 24 cents, or 1.1 percent, to $21.27. Standard Pacific Crop. Dropped 5 cents to $7.86.
The yield on the benchmark 10-year Treasury note was unchanged at 1.84 percent.
Asian indexes closed mixed after the Bank of Japan announced a new round of bond purchases that many observers thought was too weak to have much effect on the economy. The BOJ set a 2 percent inflation target and announced open-ended asset purchases starting in 2014.
Japan's Nikkei 225 index closed down 0.4 percent, while the Hang Seng in Hong Kong rose 0.3 percent. China's Shenzhen average fell 1.5 percent.
European stocks also were mixed. Germany's DAX closed down 0.7 percent despite strong results from an investor confidence survey in that country. Britain's FTSE 100 was flat; France's CAC 40 fell 0.6 percent.
Benchmark oil rose 66 cents to $96.22 at midday on the New York Mercantile Exchange, as global economic reports remain generally positive.
