July 24 (Reuters) - U.S. stock index futures rose on Tuesday, as Alphabet's strong results lifted other high-growth technology companies, adding to a robust earnings season in the backdrop of a U.S.-China trade war and a strengthening dollar.
Shares of Google-parent Alphabet, part of the so-called FAANG stocks, jumped 4.6 percent in premarket trading and were set to scale a record high after the company reported better-than-expected quarterly revenue and profit as expenses from its Google search business grew more slowly.
Other FAANG stocks also rose. Facebook climbed 1.9 percent, while Amazon gained 1.4 percent. Twitter gained 0.9 percent.
Eli Lilly jumped 6.6 percent after the company said it would take its animal health unit public and posted a better-than-expected quarterly profit.
Biogen rose 4.7 percent after the drugmaker reported a better-than-expected quarterly profit and raised its forecast for 2018 adjusted earnings.
At 6:58 a.m. ET, Dow e-minis were up 100 points, or 0.4 percent. S&P 500 e-minis were up 6.25 points, or 0.22 percent and Nasdaq 100 e-minis were up 12.75 points, or 0.17 percent.
The earnings season has been robust to date, with 82 percent of the 90 S&P 500 companies that have posted results topping profit estimates, according to Thomson Reuters I/B/E/S.
Analysts estimate of profit growth have risen to about 22 percent for the second quarter, up from 20.7 percent at the start of the month.
Investors will continue to focus on the impact of a strong dollar and the trade dispute between the United States and China on future earnings. The world's two largest economies have already imposed tariffs on $34 billion worth of each other's imports.
Whirlpool tumbled 9.9 percent, in low volumes, after reporting weak quarterly results and cutting its full-year forecasts, blaming lower volumes and higher raw material costs, especially in EMEA.
Harley-Davidson, at the center of the brewing trade war between the United States and the European Union, rose 1.1 percent in low volumes after its profit topped estimates as sales of bikes overseas edged up, although it warned new EU tariffs would squeeze margins.
