May 3 (Reuters) - Wall Street looked set to open lower on Wednesday, weighed down by Apple after the world's most valuable company by market value reported a surprise fall in iPhone sales.
Shares of Apple dropped 1.2 percent to $145.75 in premarket trading, a day after the company also forecast current-quarter revenue below estimates.
"The market is taking its cue from Apple," said JJ Kinahan, chief market strategist at TD Ameritrade in Chicago.
Akamai Technologies tumbled 13.6 percent after it gave a weak forecast for current-quarter revenue and profit. Gilead dropped 2 percent after the drugmaker reported a lower-than-expected profit.
Strong corporate reports so far had resulted in estimates for first-quarter profit growth at S&P 500 companies increasing to 13.9 percent as of Tuesday, from an estimate of 10.4 percent growth two weeks back, according to Thomson Reuters I/B/E/S.
The strong earnings have also helped offset some fears about geopolitical tensions in the Korean peninsula, the lack of progress by the Trump administration in enacting its economic agenda as well as mixed economic data.
"Strong earnings are still driving the market. Not only are earnings good, the CEOs are painting a picture of continued earnings growth and this helps trump some of the other factors," said Kinahan.
Dow e-minis were down 17 points, or 0.08 percent, with 10,743 contracts changing hands at 8:32 a.m. ET (1232 GMT).
S&P 500 e-minis were down 4 points, or 0.17 percent, with 69,077 contracts traded.
Nasdaq 100 e-minis were down 14 points, or 0.25 percent, on volume of 19,483 contracts.
Data last week showed the U.S. economy grew at its slowest pace in three years in the first quarter. Since then, automakers have reported a drop in vehicle dales for March, which along with the drop in iPhone sales, have added to nerves.
The Federal Reserve could address GDP when it issues a statement at 2 p.m. ET, at the end of its two-day meeting on interest rates. While the central bank is expected to hold interest rates steady, it may hint it is on track for an increase in June.
An ADP report showed showed U.S. private employers added 177,000 jobs in April, slightly above economists' expectations.
The data come ahead of the U.S. Labor Department's more comprehensive non-farm payrolls report on Friday, which includes both public and private-sector employment.
Yum Brands rose 2.2 percent to $67.80 after the company's quarterly profit came in better than expected.
