Citi had been concerned that higher input costs would weigh on margins and dampen management's outlook for 2011. Its assumptions proved too pessimistic. BBBY has a history of accurately assessing market conditions and guiding conservatively. Citi now views moderate gross margin degradation in 2011 as a "worst-case scenario" for the chain. BBBY is approaching peak operating margins, and shares are near the higher end of recent valuation parameters.

The company also expects operating margins to remain fairly consistent with the prior year, which suggests limited gross margin degradation.
