Market benchmark BSE Sensex rebounded from early lows to close at a new life-time high of 37,606.58 on late buying in Reliance Industries, HUL, Infosys and Hero MotoCorp, extending its record run for the seventh day in a row.
The broad-based NSE Nifty too closed at fresh record high of 11,356.50, up by 36.95 points or 0.33 per cent. The 50-share index extended its record breaking run for the fourth day.
A recovery in rupee, unabated buying by domestic institutional investors (DIIs) and encouraging earnings by blue-chips contributed to the uptrend, brokers said.
Traders were cautious ahead of RBI's monetary policy outcome on Wednesday.
Reliance Industries was the top gainer by climbing 3.14 per cent to close at record Rs 1,185.85. RIL also regained its status as the country's most valued firm by market capitalisation (m-cap), replacing Tata Group's TCS from the top slot.
Heromotocrop rose by 2.77 per cent followed by HUL that rose 2.52 per cent.
