Jan 17 (Reuters) - U.S. stock indexes were set to scale fresh record highs on Friday, on optimism over corporate earnings, fresh economic data and indications of resilience in a Chinese economy battered by a prolonged trade war with the United States.
Investor sentiment has brightened this week after the world's top two economies took the first step in calling a truce to their 18-month tariff dispute by sealing a Phase 1 trade deal.
The three main stock indexes closed at record highs on Thursday, with the S&P 500 surging past the 3,300-mark for the first time, also boosted by a rally in technology stocks and strong U.S. retail sales data.
In the final minutes of the trading session on Thursday, Google-parent Alphabet Inc became the fourth U.S. company to top a market value of over $1 trillion.
Spurring gains in global stocks for a fifth day, data showed the world's second-largest economy ended 2019 on a somewhat firmer note, even as economic growth cooled to its weakest in nearly 30 years in the last year.
Further helping stock futures, U.S. homebuilding surged to a 13-year high in December, suggesting the housing market recovery was back on track amid low mortgage rates.
"There's a lot of enthusiasm out there and it is a combination of earnings and strong data that is supporting the market," said Peter Cardillo, chief market economist at Spartan Capital Securities in New York.
"From a technical viewpoint, the market is a bit overbought and there is a possibility that the rally is going to exhaust itself at one point."
After an upbeat showing from banks earlier this week, oilfield service provider Schlumberger NV reported a slightly better-than-expected quarterly profit, sending its shares up 2.1% in premarket trading.
At 8:58 a.m. ET, Dow e-minis were up 90 points, or 0.31%. S&P 500 e-minis were up 8.75 points, or 0.26% and Nasdaq 100 e-minis were up 41 points, or 0.45%.
Among other stocks, Qualcomm Inc's shares rose 1.3% after Citigroup upgraded the stock to "buy" from "neutral".
International Business Machines Corp dropped 1.2% after Morgan Stanley downgraded the stock to "equal weight", saying information technology budgets are under pressure in 2020 and that are set to hit the hardware sector the most.
