The 30-share barometer fell by 39.69 points, or 0.20 per cent, to 19,212.92, led by losses in stocks of metal, realty, auto, banking and oil and gas sectors. The index had gained nearly 375 points in the previous two sessions.
Similarly, the wide-based National Stock Exchange index Nifty shed 17.30 points, or 0.29 per cent, to 5,801.30.
Brokers said profit booking by speculators after recent gains mainly influenced the trading sentiment but a firming trend in the Asian region, cushioned the fall to some extent.
