Rupee opens at 55.89 per dollar

Manis Thanawala, Greenback Forex Services said, "The rupee is expected to open marginally stronger on the back of stronger global equities and a weaker dollar over night. Focus now moves to the Fed as the market factors in extension of Operation Twist and also discounts possibility of the Fed further expanding the balance sheet. The range for the day is seen between 55.50-56.10/USD."
