Nervy Wall Street Edges Higher

The two-day G7 meeting being held in Canada has earned the unofficial "G6 plus one" moniker following a series of aggressive trade actions by U.S. President Donald Trump that have angered allies.

Trump threw an additional curveball at the group early on Friday when he called for Russia to be readmitted into the group.

"The G7 is usually neutral to the markets, but now there are concerns that perhaps the trade talks will deteriorate," said Quincy Krosby, chief market strategist at Prudential Financial. "It adds some caution to the market."

In recent weeks worries about a trade war have been offset by a string of largely positive U.S. economic data.

Krosby attributed Friday's mixed trading also to next week's calendar, which includes meetings of the Federal Reserve and the European Central Bank. (AFP)
