Sensex closes higher for fourth straight session; blue-chips gain

MUMBAI (Reuters) - The BSE Sensex and Nifty rose modestly on Monday to notch their fourth consecutive session of gains, led by blue-chips that have under-performed recently, such as Tata Motors and Oil and Natural Gas Corp, although the mood was broadly cautious.

Oil and Natural Gas Corp rose 3.7 percent, while Tata Motors ltd was up 3.9 percent.
