The Nifty spurted 24 points to scale a new record of 10,101 and the Sensex rallied over 100 points at the open today, fuelled by strong corporate earnings and positive global developments.

Sectoral indices metal, auto, IT, realty, healthcare and consumer durables were in the positive space, rising up to 0.99 per cent, on earnings optimism.
