Benchmark stock indices Sensex and Nifty edged lower in a volatile trade on Friday, reversing early gains due to selling in IT and select banking shares. The 30-share BSE Sensex slipped 15.44 points or 0.02 per cent to close at 73,142.80 points with 17 of its constituents closing in the red and 13 in the green. The index opened higher but later slipped into losses due to profit-taking by investors. The barometer oscillated between a high of 73,413.93 and a low of 73,022 during the day.
