Bed Bath & Beyond (NASDAQ: BBBY) fell to a five-year low last week after a weak first-quarter report. The home-goods retailer is certainly showing its maturity — a bit of graying around the edges that’s occurred over the years, though it’s tried to give itself a bit of a facelift. Recently it purchased trendy flash-sale site One King’s Lane, but that e-commerce entry might not be enough to update the retailer.
