April 22 (Reuters) - U.S. stock index futures were little changed on Friday ahead of a slew of earnings reports by industry bellwethers such as Caterpillar and McDonald's.
* Global stocks fell following disappointing U.S. quarterly results on Thursday and data that showed an unexpected slowdown in Euro zone business growth.
* With recent economic data indicating a sluggish pace of economic growth and crude prices hovering near five-month highs, earnings have become a swing factor for stocks.
* The S&P 500 has staged a sharp recovery from a steep selloff earlier this year and is inching towards its all-time high, helped by a recent rebound in oil, a cautious Federal Reserve and companies beating tempered expectations.
* S&P 500 companies are expected to post a 7.2 percent fall in first-quarter profit, according to Thomson Reuters I/B/E/S, and shares of companies failing to beat the already lowered expectations are getting hammered.
* Heavyweights Alphabet and Microsoft were down 4.4-5.4 percent premarket after both missed profit and revenue estimates.
* Starbucks slipped 3.8 percent after missing quarterly sales expectations, while Visa was down 4.4 percent after the world's largest payments network operator cut its full-year revenue forecast.
* General Electric was off 1 percent at $30.67 after it reported a dip in organic revenue.
* Caterpillar was down 1.8 percent at $77.26 ahead of its results before the bell on Friday.

* Dow e-minis were up 13 points, or 0.07 percent, with 24,744 contracts changing hands.
* S&P 500 e-minis were up 3.5 points, or 0.17 percent, with 174,471 contracts traded.
