New orders for US manufactured goods fell 1.5% in December, reversing November's gains, according to fresh data from the country’s Commerce Department.

New factory orders dropped to $489.2 billion from $496.4 billion in November. 

Much of the fall was in often-volatile civilian aircraft orders, and followed a surge in the same orders in November.

Excluding transportation equipment, which includes aircraft, new orders were up 0.2%, with strength especially in machinery for oil and gas exploration.

For the full year, new orders for manufactured goods increased 2.5% to $5.82 trillion; non-transport orders gained just 1.5% at $4.95 trillion.
