* Futures up: Dow 36 pts, S&P 0.75 pts, Nasdaq 43 pts
Aug 2 (Reuters) - U.S. stock index futures were higher on Wednesday with a rally in Apple's shares lifting the technology sector and setting the Dow industrials on course to breach the 22,000 mark.
* Apple jumped 5.68 percent in premarket trading, a day after the world's largest publicly listed company reported better-than-expected results and iPhone sales, and signaled its upcoming 10th-anniversary phone is on schedule. The stock is up about 30 percent this year.
* The S&P 500 information technology index is up 22 percent year to date, leading other sectors, as investors look for growth in an otherwise low-growth environment.
* The Dow has risen 11 percent in 2017, even as Wall Street is losing confidence that President Donald Trump and a Republican-controlled Congress will be able to cut taxes and increase infrastructure spending this year.
* The Dow hit the 20,000 mark in late January and crossed the 21,000 mark in just over a month on March 1, helped by a rise in banks Goldman Sachs and JPMorgan.
* Two-thirds of S&P 500 companies have reported their second-quarter earnings so far and 72 percent of them have beaten Wall Street's expectations, according to Thomson Reuters I/B/E/S. In a typical quarter, 64 percent of companies beat expectations.
* The results may reassure investors worried about high valuations. The S&P 500 is trading at about 18 times earnings estimates for the next 12 months, above its 10-year average of 14 times, according to Thomson Reuters Datastream.
* Tesla, Fitbit and AIG are among the major companies scheduled to report results after the closing bell.
* The ADP data at 8:15 a.m. ET (1215 GMT), is expected to show U.S. private employers added 185,000 jobs in July, after adding 158,000 jobs in June. The data comes ahead of the more comprehensive non-farm payrolls data on Friday.
* San Francisco Fed President John Williams and Cleveland Fed chief Loretta Mester are also scheduled to make appearances later in the day.
* Match Group fell 6.03 percent after the dating website operator's quarterly profit came in below expectations.
* Garmin rose 5.22 percent as the maker of GPS-based gadgets, reported a rise in quarterly profit.
* FireEye was up 6.74 percent after the internet security company's revenue came in above expectations.
* Time Warner Inc was marginally up, after the company reported a better-than-expected 11.6 percent jump in quarterly profit.
