Mumbai: The SENSEX opened firm and later was trapped in a narrow range in line with a mixed trend at early stages on the Bombay Stock Exchange (BSE) on July 4 on fresh buying support alternated by profit booking.

The BSE sensitive index opened remarkably up at 3,322.31 as against previous close of 3,310.19 and later fluctuated in a range of 3,329.96 and 3,317.69 before being quoted at 3,319.23 at 10:30 hours (IST).

The up trend in the BSE barometer was largely because of a fresh rally in Infosys Technologies and Satyam Computers which continued their upsurge on fresh purchases by foreign institutional investors that have been consistent net buyers for the last six sessions from June 25 onwards.

The sentiment was partly aided by a stocks boost on Wall Street on July 3 despite a revenue warning from advanced micro devices. The Dow Jones industrial average closed up by 47.22 and the NASDAQ rose by 22.28 on July 3.

Old economy stocks like TISCO, HPCL, TELCO and HLL were quoted moderately lower on selling pressure.
