The market has opened on a flat note. The Sensex is up 38.58 points at 24909.27, and the Nifty is up 24.90 points or 0.3 percent at 7588.45. About 506 shares have advanced, 105 shares declined, and 31 shares are unchanged. L&T, Lupin, BHEL, SBI and Axis Bank are top gainers while Hero, ICICI Bank, ITC, NTPC and Dr Reddy’s Labs are losers in the Sensex. The rupee opened flat at 67.77 per dollar against Friday’s close of 67.78. Agam Gupta of Standard Chartered said, “The risk sentiment remains positive due to the negative interest rates announced by Bank Of Japan last week. We expect a range of 67.60-67.95/dollar for the USD-INR today.” The dollar rose sharply on Friday, hitting a six-week high versus the yen, after the Bank Of Japan took one of its main interest rates into negative territory and US gross domestic product data largely matched economists’ expectations.
