The benchmark Sensex dipped by about 100 points in early trade on Monday on profit-selling by funds and speculators amid a weak trend in other Asian stock markets.
The Bombay Stock Exchange barometer fell by 99.60 points, or 1.20 per cent, to 8,226.22 points with all sectoral indices trading in the negative zone.
The 50-share National Stock Exchange's Nifty dipped below the 2,600 level declining by 31.05 points to 2,589.10 points.
Marketmen said a weak trend in the Asian stock markets and profit-taking by speculators after previous session's recovery mainly led to a fall in the stock prices.
