NEW YORK (AFP) - The Nasdaq surged to a fresh record on Wednesday (Jan 8), as the major US indices all rose amid diminished anxiety over the US-Iran conflict in the wake of an attack on American troops.
The tech-rich Nasdaq Composite Index finished up 0.7 per cent at 9,129.24, eclipsing a January 2 record by almost 40 points.
The Dow Jones Industrial Average gained 0.6 per cent to close at 28,745.09, while the broad-based S&P 500 added 0.5 per cent to 3,253.05.
Wall Street opened the session cautiously following a series of missile attacks by Iran on bases hosting US and other foreign troops in neighbouring Iraq.
The strikes were Iran's first concrete retaliation over the US killing of a top Iranian commander.
Iran's supreme leader Ayatollah Ali Khamenei vowed there was more to come, but President Donald Trump said Teheran appeared to be "standing down" after the missile attack caused no casualties.
"At least for now, the retaliation is behind us," said Art Hogan, chief market strategist at National Securities. "The market can move on."
Hogan said investors are focused on an expected signing of a US-China trade accord next week, and upcoming quarterly earnings season.
