Major stock markets mostly retreated Friday with shares in tech giant Nvidia that have fuelled the equities rally failing to rebound following a day of profit-taking.
Shares in Nvidia, which tumbled 3.5 percent on Thursday, slid another 2.3 percent as trading got underway on Friday.
"Nvidia's reversal had a lot to do with the Nasdaq breaking a seven-session win streak," said market analyst Patrick O'Hare at Briefing.com.
"It basically took the wind out of the market and became a cue for profit-taking activity in other momentum-fuelled stocks," he added.
The Nasdaq Composite slid 0.2 percent at the opening bell on Friday. The blue-chip Dow edged higher and the S&P 500 dipped lower.
O'Hare described the situation as "normal at this point for a market -- and some specific stocks -- that have come a long way in a short amount of time and are due for some consolidation."
On the corporate front, British soft drinks manufacturer Britvic fizzed eight percent higher following news that it has rejected a takeover approach worth £3.1-billion ($3.9 billion) from Danish beer giant Carlsberg, arguing that it significantly undervalued the maker of Robinsons squash.
