a tale of two discounters...,

cbsnews | This holiday season, the biggest discount chains in the U.S. will tell the tale of two very different shoppers: Those that have and those that have not.

Walmart (WMT), the world's largest retailer, on Thursday acknowledged that its low-income shoppers continue to struggle in the economy and issued an outlook for the fourth quarter -- which encompasses the holiday shopping period -- that falls below Wall Street estimates. On the same day, its smaller rival Target (TGT), which caters to more affluent shoppers, said it expects results during the quarter to exceed the Street's projections.

The two discounters offer valuable insight into how Americans will spend in November and December, a period that's traditionally the busiest shopping period of the year. Some merchants depend on the holiday shopping season for up to 40 percent of their annual sales, but economists watch the period closely to get a temperature reading on the overall mood of American consumers.

The forecasts seem to confirm a trend that has taken shape during the economic downturn. Well-heeled shoppers spend more freely as the economy begins to show new signs of life, while consumers in the lower-income brackets continue to hold tight to their purse strings even as the housing and stock markets rebound.

Walmart and Target both are discounters, but they cater to different customers. Walmart, which says its customers' average household income ranges from $30,000 to $60,000, hammers its low-price message and focuses on stocking basics like tee shirts and underwear along with household goods. But Target, whose customers have a median household income of $64,000 a year, is known for carrying discounted designer clothes and home decor under the same roof as detergent and dishwashing liquid.
