July 18 (Reuters) - Wall Street's main indexes edged lower on Thursday as investors digested a slew of mixed earnings, while Netflix reported a surprise fall in U.S. subscribers in a downbeat start to results from high-growth companies.
Shares of the streaming pioneer sank 11.4% to their lowest since late-January at $321.10, 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, 1.28% lower.
"The stock market seems to be running out of energy," said John Augustine, chief investment officer of Huntington Private Bank in Columbus, Ohio.
"Earnings have met expectations but companies are being cautious about future quarters, which is something that's not able to keep the S&P 500 above the 3,000 level."
As second-quarter earnings rolled in this week, the three main Wall Street indexes retreated slightly from record highs and are set for their steepest weekly fall in seven weeks.
Investors are looking for concrete developments in trade talks between United States and China, while they await the Federal Reserve's policy meeting at the end of July where the central bank is widely expected to cut interest rates.
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.
