The market opened on a firm note this morning on positive global cues. After moving up further subsequently, it retreated a bit after the government released the GDP data for the March 2011 quarter, but recovered swiftly and kept moving higher as the session progressed with the slower than expected growth in the March quarter resulting in hopes that the central bank will refrain from coming out with stringent monetary tightening measures in the near future.
