Heavyweights Infosys and Reliance Industries dragged the index lower even as ITC and Tata Motors provided some support.

The S&P BSE Sensex opened higher at 20449. It traded within a band of 20348.06 to 20482.67 before closing at 20420.26, a drop of 4.76 points.

The 50-share CNX Nifty on the National Stock Exchange eased by two points to 6057.10.

Rupee up 36 paise

The rupee climbed 36 paise to a three-week high of 62.14 against the dollar on Wednesday after banks and exporters sold the U.S. currency as it weakened overseas.

The rupee resumed higher at 62.45 a dollar against the previous close of 62.50 at the inter-bank foreign exchange market and firmed up further to end at 62.14, a gain of 36 paise or 0.57 per cent. — PTI
