A gauge of US business investment plans fell in November and the prior month's increase was revised sharply lower as the drag on manufacturing from a strong dollar and spending cuts in the energy sector showed little sign of abating.
But the outlook for the US economy remains encouraging, with other data showing consumer sentiment at a five-month high in December and personal income rising for an eighth straight month in November.
That should support consumer spending and economic growth in the fourth quarter and early in 2016.
"The gain in income should prove a tailwind to fourth-quarter GDP growth as consumption remains the most prominent driver of domestic growth activity," said Gennadiy Goldberg, an economist at TD Securities in New York.
The Commerce Department said non-defence capital goods orders excluding aircraft, a closely watched proxy for business spending plans, dropped 0.4 per cent last month.
