Barring select software pivotals like Mastek, Satyam Computer, Pentafour Software and Zee Telefilm, most of the counters witnessed limited activity during the session. As it was the last day of weekly trading cycle, players were busy in squaring up their positions.

Dealers said trade was listless in the absence of market-moving news and little institutional support. But select buying in index-based shares like Hindalco, Gujarat Ambuja Cements and Mahindra & Mahindra helped sentiment, they said.
