[NEW YORK] Wall Street stocks finished a choppy session mostly higher as Intel rallied on an executive shakeup while investors monitored a debate on impeaching US President Donald Trump.

Investors largely shrugged off the happenings in Washington, where Mr Trump was impeached for the second time in a House vote that finished after the market closed.

The Federal Reserve said most regions of the US reported "economic activity increased modestly," and employment rose, albeit slowly, while housing sales remained strong and manufacturing stayed on an upward trajectory.

The Dow Jones Industrial Average ended down less than 0.1 per cent at 31,060.47.

The broad-based S&P 500 added 0.2 per cent at 3,809.84, while the tech-rich Nasdaq Composite Index advanced 0.4 per cent to 13,128.95.

Markets remain near all-time highs as investors bet on an improving 2021 economy in anticipation of more US stimulus once Joe Biden is inaugurated as president.
