Besides, the Nifty IT index hit its highest level in a year (52 week high) on Wednesday, owing to the weakness in the rupee over surging oil prices which may benefit the export-oriented sector.

Government 10-yr yield slid as the RBI announced open market operation while the rupee weakened due to uncertainty in oil prices," said Vinod Nair, Head of Research, Geojit Financial Services.
