The Dow industrials ended at a record high on Friday and major indexes closed a third consecutive week of gains as upbeat economic data and the start of earnings season gave investors confidence.
But equity futures fell after the closing bell following reports of a coup in Turkey. The military said it had seized power, but the Turkish Prime Minister later asserted the attempted coup was put down.
"US (Treasury) yields have fallen, the Turkish lira plummeted, gold is up, you could call it a textbook response to this kind of situation," said Brian Jacobsen, chief portfolio strategist at Wells Fargo Funds Management in Menomonee Falls, Wisconsin.
"How it plays out depends on what the effects are by the time markets open on Monday. It is unclear right now who is in control," he said.
A US exchange-traded fund that follows the Turkish stock market dropped sharply near the end of the session and was down 6 per cent after the bell.
S&P 500 e-mini futures hit a session low down 0.65 per cent after the reports, but pared the loss and were down 0.5 per cent.
Jacobsen added: "I don`t think this spills over to other countries. This isn’t like the Arab Spring of 2011 where there was a cascade of anti-government protests in favour of democratic reforms. The issues Turkey is wrestling with seem unique to Turkey."
'US retail sales rose more than expected in June'
During the normal-hours session, consumer stocks led declines on the S&P 500 while the financial sector posted a less than 0.2 per cent drop, even as Wells Fargo, whose profits fell in the second quarter, fell 2.5 per cent to $47.71 to rank as the largest weight on the S&P.
But expectations for S&P earnings ticked up to a 4.7 per cent decline from a view of a 5-per cent drop earlier in the week, cementing hopes that an earnings contraction bottomed in the first quarter.
Adding to investor confidence, US retail sales rose more than expected in June, bolstering views that economic growth picked up in the second quarter.
"When you go into earnings season with negative bias in the market it bodes well for stocks. Any positive surprises will force shorts to cover and gives an upbeat tone," said Quincy Krosby, market strategist at Prudential Financial in Newark, New Jersey.
