NEW YORK, Jan 23 U.S. stock index futures pointed to a flat open on Wednesday, with investors reluctant to make big bets following a five-day rally that took major averages to levels not seen since December 2007.
Tech shares will be in focus with earnings due from tech heavyweight Apple and following strong results from both IBM and Google, which rallied in premarket trading and continued the string of major companies outperforming following results.
Google Inc rose 5.1 percent to $738.65 in premarket trading a day after the search giant's core Internet business outpaced expectations. Revenue was also higher than expected.
International Business Machines Corp late Tuesday forecast better-than-anticipated 2013 results and also posted fourth-quarter earnings and revenue that beat expectations. The results helped to allay concerns about the tech sector after Intel Corp gave a weak outlook last week. IBM, which is a Dow component, rose 3.8 percent to $203.57 before the bell.
While a number of major companies reported on Wednesday, including Dow components McDonald's Corp and United Technologies Inc, the focus for investors may be Apple Inc, which is due to report after the market closes.
Investors will scour results from Apple, the most valuable U.S. company, for signs the tech giant can continue to grow at an accelerated pace. The stock has been pressured recently by questions raised about demand for Apple's prospects. The stock edged 0.5 percent higher to $507.34 in premarket trading.
"The market has an upward bias because earnings have generally been better than most expected, but whether we take another leg up from here depends on Apple," said Oliver Pursche, president of Gary Goldberg Financial Services in Suffern, New York. "That is such a heavily watched stock that if it doesn't come out with strong numbers we could take a pause."
McDonald's edged higher 0.6 percent $93.55 in premarket trading after reporting a rise in fourth-quarter earnings, lifted by an increase in same-store sales. United Tech's earnings fell from the prior year, hurt by large restructuring charges.
Coach Inc slumped 16 percent to $50.75 before the bell after reporting sales that missed expectations.
S&P 500 futures fell 2.6 points and were slightly under fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures fell 10 points and Nasdaq 100 futures rose 1.75 point.
Both the S&P 500 and Dow Jones industrial average hit five-year closing highs on Tuesday, and recent gains have largely been fueled by a strong start to the earning season. The S&P has jumped 6.4 percent over the past four weeks.
According to the latest Thomson Reuters data, of the 74 S&P 500 companies that have reported earnings so far, 62.2 percent have topped expectations, roughly even with the 62 percent average since 1994, but below the 65 percent average over the past four quarters.
Overall, S&P 500 fourth-quarter earnings rose 2.6 percent, according to Thomson Reuters data. That estimate is above the 1.9 percent forecast from the start of earnings season, but well below the 9.9 percent fourth-quarter earnings forecast from Oct. 1, the data showed.
Republican leaders in the U.S. House of Representatives aim on Wednesday to pass a bill to extend the U.S. debt limit by nearly four months, to May 19. The White House welcomed the move, saying it would remove uncertainty about the issue.
The debt limit issue has hung over the market for weeks, with many investors worried that if no deal is reached to raise the limit, it could have a negative impact on the economy.
"We're raising our year-end target from 1,535 to about 1,575, in part because of the strong fourth-quarter earnings, but also because with the debt ceiling off the table that's a headwind removed from the market," Pursche said.
