The Bombay Stock Exchange benchmark Sensex was down by over 187 points at 11 hours on profit-booking by funds and overseas investors.
The Sensex, which gained nearly 95 points in opening trade, fell back to trade 187.48 points lower at 19,321.41 by 1100 hrs
Similarly, the broad-based National Stock Exchange index Nifty dipped below the 5,800-point level by falling 61.45 points to 5,795.90 at the same time.
However, metal sector stocks remained strong and cushioned the fall, after metal prices surged in global markets supported by increased imports by China, the world’s largest consumer of metals.
