The benchmark Sensex rose over 100 points to trade above the 28,000 mark in early trade on Friday as value-based buying in consumer durables, healthcare, power, capital goods and auto sectors took the recovery forward.
With this, the index brushed off losses in other Asian markets ahead of the Greece referendum.
The 30-share gauge, which had lost 75.07 points in Thursday's volatile session, recovered 100.95 points, or 0.36 per cent, at 28,046.75.
Similarly, the 50-share Nifty edged up 23.50 points, or 0.28 per cent, to 8,468.40 in early trade.
Brokers said fresh buying by investors at prevailing levels and RBI Governor's statement on Thursday that India's exposure to Greece is limited influenced sentiment.
They said, however, a weak trend at other Asian markets due to uncertainties surrounding the Greece referendum limited the gains in the domestic bourses here.
Among other Asian markets, Japan's Nikkei fell 0.44 per cent while Hong Kong's Hang Seng shed 0.27 per cent in early trade on Friday.
The US Dow Jones Industrial Average ended 0.16 per cent lower in Thursday's trade.
