The BSE benchmark Sensex on Friday moved up by another 37 points in early trade, on continued buying by funds and retailers even as trend on other Asian markets remained slightly subdued.

The 30-share index rose further by 37.08 points, or 0.21 per cent, to 17,468.92. It has gained over 568 points in the past three sessions.

In a similar fashion, the wide-based National Stock Exchange Nifty index gained 9.45 points, or 0.17 per cent, at 5,279.35.

Healthcare, power, PSUs, IT and oil and gas sector stocks maintained their upward journey, helping Sensex to trade in the positive zone.

Brokers said continued buying by FIIs on the Indian bourses and encouraging quarterly earnings by some corporates mainly buoyed the trading sentiment but a weak trend on other Asian bourses, capped the gains here.
