HDFC Bank climbed 1 per cent after the country\'s No. 3 lender reported a higher-than-expected 31.2 per cent rise in quarterly profit as a drop in loan-loss provisions and higher fee income made up for weak loan demand.

The 30-share BSE index closed up 1.17 per cent at 16,643.74, its highest close since December 7. Twenty-three of its components gained. \"The confidence is back,\" said K.K.
