Closing bell: Sensex ends up, but posts first weekly loss in four weeks

Key indexes ended slightly higher on Friday led by shares of some metals firms as commodity prices rallied, but the unease in global markets about North Korea put a lid on gains.

The BSE Sensex ended 0.08 percent higher at 31,687.52, while the broader NSE Nifty closed 0.05 percent up to 9,934.80.

Both indexes, however, ended the week lower, snapping a third weekly run of gains. For the week, the NSE and BSE ended 0.40 percent and 0.64 percent lower respectively.
