Nvidia (NVDA.O) was a big drag, down 3.7% after a report said U.S. curbs could force the chip designer to cancel billions of dollars of orders to China.

An October reading of Chicago PMI came in at 44 against expectations of 45, while a separate reading showed U.S. labor costs increased solidly in the third quarter.
"The slightly stronger increase in the employment cost index in the third quarter is another sign that the earlier rapid easing in labour market conditions may be fading," said Andrew Hunter, deputy chief U.S. economist at Capital Economics.
"But the forward-looking evidence still suggests wage growth will slow further over the coming months."
