NEW YORK -- The Standard & Poor's 500 index eked out its second small gain of the week Wednesday as investors pored over the latest earnings reports.
Norfolk Southern climbed after the railroad company said its fourth-quarter profit rose 24 percent, better than Wall Street analysts had forecast. TE Connectivity, an electronics company, was the biggest gainer in the S&P 500 after its earnings beat analysts' expectations and the company posted a strong earnings outlook for the second quarter.
But there were also some high-profile disappointments.
IBM fell after the computing company reported lower-than-expected revenue in the period. AMD slumped after the chipmakers' first-quarter revenue outlook rattled investors.
Companies are still increasing their earnings and are forecast to log record quarterly profits for the period, but much of the improvement in recent years has come from cutting costs. As the economy strengthens, investors are increasingly looking for evidence that companies can increase revenue.
"There's not a lot of cost left for companies to squeeze out," said Andy Zimmerman, chief investment strategist at DT Investment Partners, an investment advisor.
The S&P 500 index rose 1.06 point, or 0.1 percent, to 1,844.86. The index traded within a range of just six points on Wednesday. After a small gain on Tuesday, the index is six points, or 0.3 percent, higher for the week.
The Dow Jones industrial average fell 41.10 points, or 0.3 percent, to 16,373.34. Most of the Dow's losses came from IBM's slump. The computer service company's stock fell $6.18, or 3.3 percent, to $182.25.
In other trading, the Nasdaq composite climbed 17.24 points, or 0.4 percent, to 4,243.
Among the day's winners, TE Connectivity jumped $3.70 or 6.6 percent, to $60 after its earnings report. Norfolk Southern climbed $4.23, or 4.8 percent, to $92.94 after the rail company said its fourth-quarter profit rose 24 percent.
Despite the lackluster start to the year, most investors see no cause to call an end to the stock market's rally just yet. The S&P 500 is down 0.2 percent in 2014 after a gain of almost 30 percent last year.
"You had a massive run last year," said Russ Koesterich, chief investment strategist at BlackRock. "And it's not unreasonable that the market digests those gains."
So far, the stock market has failed to get a lift from the company earnings reports that have come out.
Companies are forecast to increase their fourth-quarter earnings by 5.4 percent over the same period a year earlier to a record $27.77 a share, according to S&P Capital IQ data. That would be a slight decline from the third quarter growth rate of 5.6 percent and lower than last year's pace of 7.7 percent.
Much like last year, small companies are again outperforming their larger counterparts. While the S&P 500 has moved sideways since the start of year, the Russell 2000, an index that tracks smaller companies, is up 1.5 percent. The Nasdaq composite is up 1.6 percent.
In government bond trading, the yield on the 10-year Treasury note climbed to 2.86 percent from 2.83 percent late Tuesday.
Among other stock making big moves:
• Apple climbed $2.44, or 0.4 percent, to $551.51. Billionaire investor Carl Icahn said on his Twitter account that he had increased his investment to more than $3 billion. Icahn wants Apple to "markedly" increase its share buybacks and said the technology company is doing investors a disservice by not doing so.
• Netflix surged $55, or 16 percent, to $388 in after-hours trading after the video streaming company posted earnings that beat analysts' expectations and added another 2.3 million U.S. subscribers.
• Coach fell $3.17, or 6 percent, to $49.38 after the luxury goods maker reported a lower quarterly profit, citing weakness in women's bags and accessories in North America. Coach is facing tough competition from rivals like Michael Kors.
• Advanced Micro Devices plunged 50 cents, or 12 percent, to $3.67 after the company said late Tuesday that it expected its first-quarter revenue to fall 13 percent to 19 percent from the fourth quarter. That would translate into first-quarter revenue ranging from $1.29 billion to $1.38 billion, mostly below Wall Street's predictions.
