Market came under a spell of volatility as the Sensex slipped into the negative zone from a positive start after profit-booking resurfaced at FMCG, auto and realty counters despite higher Asian cues.
Investors went in for profit-booking after yesterday's biggest single-day rebound in close to five months. But oil and gas, healthcare, energy, utilities, consumer durables, power and IT sectors saw continued buying interest.
The 30-share index resumed higher at 28,112.36 and hovered between 28,131.07 and 27,976.73 before quoting at 28,005.92 at 1144 hours, lower by 44.96 points, or 0.16 per cent.
The 50-share Nifty went down 12.85 points, or 0.15 per cent, to 8,665.05.
Foreign portfolio investors (FPIs) bought shares worth a net Rs 345.04 crore yesterday, showed provisional data.
Overseas, Asian markets were trading higher tracking overnight gains in US stock markets. US stocks registered modest gains yesterday, helped by stronger-than-expected quarterly reports after mixed inflation data.
