Mumbai, Nov 17: Key Indian equities indices opened higher on Tuesday in line with a rally in the US and a surge in Asian stocks, but sentiments remained cautious on the back of some not-too-encouraging news on factory output growth, inflation and exports.
Some 15 minutes into trading, the key index was ruling at 25,823.29 points, with a gain of 63.19 points (0.25 percent).
The Sensex had closed 149.57 points (0.58 percent) higher on Monday.
At the National Stock Exchange, the broader 50-share Nifty was ruling at 7,824.70 points, with a gain of 18.10 points (0.23 percent) against the previous close at 7,806.60 points.
This index had gained 44.35 points (0.57 percent) on Monday.
"The US markets opened in the red following concerns about a wider conflict after the Paris attacks. However, the markets changed direction and ended firmly in positive," said a pre-open analysis by Angel Broking, a share trading and wealth management facilitator.
"European markets also pulled back in early trade following the terrorist attacks. However, the markets recouped most of their losses to close marginally in the red. Travel and leisure stocks were under pressure, but gains in energy stocks helped to offset that impact."
