 "Wall Street")
US stocks fell on Thursday morning, dragged down by media companies, while results from JPMorgan and Citigroup failed to fuel the optimism that has driven indexes to record highs.
JPMorgan and Citigroup, which had already talked down third-quarter expectations, reported earnings that were better than Wall Street estimates even as trading revenues fell. The shares of both companies were little changed.
"After a long stretch of consecutive highs in the market, with earnings, even if they are slightly disappointing, or an even an aspect of earnings like bond trading at JPM, is more an excuse to sell off," said Scott Clemons, chief investment strategist at Brown Brothers Harriman in New York.
With the S&P 500 up about 14 per cent in 2017, investors are betting on strong earnings growth across the S&P 500.
AT&T tumbled 3.22 per cent after the company said its third-quarter results took a hit from the string of hurricanes.
The company also said it lost video subscribers in the quarter. Brokerage Guggenheim downgraded Disney and Viacom on worries over subscriber declines
That sparked fresh jitters in a sector that was hit a day earlier by President Donald Trump's suggestion to challenge TV network licenses over 'fake news'.
Comcast fell 2.8 per cent, Disney fell 1 percent. Viacom sank 6.6 per cent after warning that Charter Communications subscribers may lose access to its channels as the expiration looms for a distribution deal.
Clemons said earnings will probably heighten volatility, with lack of any other major developments to drive the market.
