July 18 (Reuters) - U.S. stock indexes edged lower on Thursday as investors awaited more developments around trade, while Netflix posted a surprise drop in U.S. subscribers, kicking off earnings for the FAANG group of stocks on a sour note.
Shares of the streaming pioneer sank 11.3% and weighed on the S&P 500 and the Nasdaq as the company also missed targets for new subscribers overseas at a time when it has staked its future on global expansion.
Losses in Netflix also dragged the communication services sector, one of the best-performing S&P sectors so far this year, 1.20% lower.
"Netflix did nothing to soothe investor concerns around what earnings prospects are likely to unfold over the next couple of weeks," said Mark Luschini, chief investment strategist at Janney Montgomery Scott in Philadelphia.
The disappointing earnings so far have amplified the pressure on markets from trade worries, he said.
The three main Wall Street indexes have retreated slightly from record highs this week as second-quarter earnings rolled in.
"With the run we've had in the market, conditions have been overbought and in that light the market have been right in releasing some of that pressure from the rally."
In trade-related news, U.S. Treasury Secretary Steven Mnuchin said U.S. and Chinese officials will hold a telephone call later on Thursday that could pave the way for further in-person trade talks.
Investors also await the Federal Reserve's policy meeting at the end of July where expectations of an interest rate cut are very high.
At 10:00 a.m. ET, the Dow Jones Industrial Average was down 13.47 points, or 0.05%, at 27,206.38, the S&P 500 was down 2.60 points, or 0.09%, at 2,981.82. The Nasdaq Composite was down 16.07 points, or 0.20%, at 8,169.14.
