NEW YORK (Reuters) - Concerns that a trade deal between the U.S. and China may not be imminent reined in a rally in world equity markets and reversed gains on Wall Street on Friday, while strong U.S. wage growth boosted U.S. bond yields.
Markets had earlier climbed on hopes that the world's two biggest economies were mending their shaky trade relations.
A steep decline in shares of Apple Inc (NASDAQ:AAPL) further weighed down sentiment in the U.S. stock market after the iPhone maker warned sales for the crucial holiday quarter would likely miss expectations.
A senior official in the administration of U.S. President Donald Trump on Friday dismissed as untrue a media report that said Trump was preparing a possible trade deal with China, a CNBC reporter said in a post on Twitter.
"There is a long way to go" on negotiations, the unnamed official told CNBC's Eamon Javers, according to his tweet.
That erased earlier gains in the U.S. stock market and curtailed a rally in global shares that had lifted emerging market stocks up by their largest daily gain since 2016.
In Europe, Germany's export-heavy DAX (GDAXI) had jumped as much as 1.5 percent, its best session since July, before giving up most of its gains.
The pan-European STOXX 600 index (STOXX) rose 0.30 percent and MSCI's gauge of stocks across the globe (MIWD00000PUS) gained 0.13 percent.
The Dow Jones Industrial Average (DJI) fell 125.44 points, or 0.49 percent, to 25,255.3, the S&P 500 (SPX) lost 20.32 points, or 0.74 percent, to 2,720.05 and the Nasdaq Composite (IXIC) dropped 89.41 points, or 1.2 percent, to 7,344.65.
Apple's shares tumbled 6.8 percent, taking its market value below $1 trillion, after the iPhone maker warned sales for the crucial holiday quarter would likely miss expectations.
U.S. job growth rebounded sharply in October and wages recorded their largest annual gain in 9-1/2 years, pointing to further labor market tightening that could encourage the Federal Reserve to raise interest rates again in December.
