Some 15 minutes thereafter, the key index was ruling at 16,719.77 points, with a loss of 65.88 points, or 0.39 percent, data with the exchange showed.

In fact, all the 13 sector-specific indices of the exchange were in the negative territory. Among the 30 Sensex stocks, 20 were in the red, with state-run power utility NTPC leading the gainers, while Reliance Infrastructure led the losers.
