NEW YORK, April 26 (Reuters) - U.S. stock index futures dipped on Friday, indicating the S&P 500 may snap a five-day winning streak ahead of data on economic growth and consumer sentiment.
* Economic data due at 8:30 a.m. EDT (1230 GMT) is expected to show U.S. economic growth likely rebounded in the first quarter after nearly stalling at the end of 2012, but the trend is likely temporary.
* Gross domestic product probably grew at a 3.0 percent annual rate, quickening from the fourth quarter's pedestrian 0.4 percent pace, according to a Reuters poll of economists.
* Later in the session at 9:55 a.m. (1355 GMT), investors will eye the Thomson Reuters/University of Michigan Surveys of Consumers final April consumer sentiment index. Economists expect a reading of 73.2, compared with 72.3 in the preliminary April report.
* Starbucks Corp slipped 3 percent to $58.70 in light premarket trading after the world's biggest coffee chain posted a quarterly profit that matched Wall Street estimates but posted revenue that was slightly below expectations.
* S&P 500 companies expected to report earnings on Friday include Dow component Chevron Corp, Flir Systems and Goodyear Tire & Rubber.
* Amazon.com Inc's revenue growth slowed in the first quarter as the world's largest Internet retail struggled overseas, but margins jumped on lower shipping expenses and the expansion of more profitable new businesses.
* S&P 500 futures fell 5.9 points and were below 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 lost 46 points, and Nasdaq 100 futures declined 11 points.
* Forest products company Weyerhaeuser Co reported a first-quarter net profit that more than tripled due to a recovery in the U.S. housing market, and said it expects higher volumes for all its wood products for the current quarter.
* According to Thomson Reuters data through Thursday morning, of the 235 companies in the S&P 500 that have reported earnings to date for Q1 2013, 67.7 percent have reported earnings above analyst expectations, above the 63 percent average since 1994 and slightly above the 67 percent beat rate over the past four quarters.
* However, revenue has been lackluster, with only 41.4 percent having topped analyst forecasts, well below the 62 percent average since 2002 and the 52 percent beat rate for the last four quarters.
*Analysts now see earnings growth of 3.6 percent this quarter, up from expectations of 1.5 percent at the start of the month.
* European shares were lower, with disappointing earnings encouraging investors to book profits after five straight sessions of gains.
* Asian shares rose, tracking global equities higher after an upbeat report on the U.S. labor market.
