The 30-share barometer, which gained nearly 120 points in the previous two sessions, fell by 95.18 points, or 0.51 per cent, to 18,400.44, with FMCG, banking, IT and capital goods stocks leading the decline.
Similarly, the wide-based National Stock Exchange Nifty index moved down by 29.65 points, or 0.53 per cent, to 5,526.50 points.
According to market experts, the fall in stock prices was mostly due to the emergence of profit-booking following two sessions of gains, besides the absence of positive cues.
In addition, a subdued trend on other Asian bourses following overnight losses in the US market dampened the market sentiment at home.
In Asia, Hong Kong`s Hang Seng index shed 0.93 per cent and Japan`s Nikkei was trading 0.32 per cent down this morning. In the US, the Dow Jones Industrial Average ended 0.16 per cent lower in yesterday`s trade.
