Department-store chain Nordstrom Inc. on Tuesday offered up a slightly more optimistic full-year sales outlook and reported third-quarter results that beat analysts’ expectations, helped by demand for women’s clothing and gains at its off-price Rack stores.

Department-store chain Nordstrom Tuesday boosted the low end of its full-year projections, although its CEO warned that there was a “noticeable decline” in sales trends at the end of last month.
