Macy’s, the largest department store chain in the United States, on Wednesday raised its sales forecast for the year after reporting a better-than-expected performance across its brands.

Macy’s recorded comparable sales growth of around 3% for the three months through Nov. 1, the strongest result in more than three years. It credited the year-over-year growth to its broad product offering, from discounted apparel to luxury goods.

The results highlight a key feature of the U.S. economy: While some shoppers are seeking discounts and cutting back on discretionary purchases, the highest-income consumers are spending relatively freely at more upmarket stores like Bloomingdale’s, which is owned by Macy’s.

The top 10% of households in the United States make up nearly half of all spending, according to Moody’s Analytics.

Sales at Bloomingdale’s were up nearly 9% in the latest quarter, a much faster pace than in previous periods. Bloomingdale’s is expanding its offering of luxury brands, including Totême, Zimmermann and Christian Louboutin, the CEO of Macy’s, Tony Spring, said on an analysts call.

For the full year, Macy’s said, its comparable sales will probably come in flat to up half a percent, an improvement over its previous forecast, which predicted an annual decline in sales of as much as 1.5%. It was the second quarter in a row that the retailer upgraded its outlook, as a turnaround effort looked to be showing results.

Macy’s, whose customer base is primarily in the middle- and upper-income tiers, said last year that it would close about 150 underperforming stores over the next several years, while opening new Bloomingdale’s and Bluemercury stores. Bluemercury’s sales were driven by high-end skin care products and brand partnerships, Macy’s executives noted.

Also on Wednesday, Dollar Tree reported better-than-expected quarterly earnings and raised its full-year forecast. The chain, which is primarily geared toward lower-income consumers, had gained traction by attracting “a wide range of shoppers,” according to its chief executive. Its stock, which jumped in early trading, has risen more than 40% this year.

Bumper results from Bloomingdale’s and Dollar Tree on the same day neatly underscored the divided nature of the consumer economy.

The retail industry overall has proved more resilient than feared.
