Investors braced for a key monthly jobs report, with the Middle East crisis and a return to work at US ports also in high focus.

Stocks rallied after data showed nonfarm payrolls grew by 254,000 jobs in September, far outpacing the forecasted gain of 150,000 from economists polled by Dow Jones. The unemployment rate ticked down to 4.1% despite expectations for it to hold steady at 4.2%.
