"Wal Mart Stores (NYSE: WMT), the world's largest retailer, with $405 billion in revenues last year, has remained remarkably strong during the recession even as other retailers have floundered," says Stephen Leeb.

In his The Complete Investor, he explains, " Its low prices have lured more customers, while its product line-up emphasizes items seldom cut from consumer budgets, such as food and health care products." Here's his review.

"Its Wal-Mart stores draw an estimated 100 million people a week, explaining why the company dominates the U.S. supermarket industry, with a better than 25% market share. The company also sells under numerous other names, including Sam's Club.

In early 2008, Toby Smith forecast a shift among consumers towards discount retailers; in ChangeWave Investing, he still looks to Wal-Mart (NYSE: WMT) and Fred's (NASDAQ: FRED) as the best way to participate in this ongoing trend.

"Consumers are worried about their jobs and about trying to build savings, so the last thing they are apt to do is spend frivolously.

"Early in 2008, our ChangeWave Alliance accurately picked up a major transformational shift in retailing as consumers began to increase spending at discounters. That shift became even more dramatic, as the economic downturn worsened in Q4 2008.

"If you're going to stay invested, you should look to defensive sectors," explain Ron Rowland and Brandon Clay, who point to consumer staples as a top pick for the current market environment.

In their Invest with an Edge, the advisors explain, "Perhaps the best way to stay defensive is with the Consumer Staples Select Sector SPDR (NYSE: XLP), an exchange traded fund.

"In a bear market, opportunities are usually limited to certain sectors. Surveying the investment horizon, we think the consumer staples sector has the best opportunity for growth in this economy.

"Regardless how the economy acts, people still eat. Consumers may not shop at Whole Foods, but they'll still buy groceries. Companies like Wal-Mart (NYSE: WMT) and Safeway (NYSE: SWY) will continue to rake in revenues from hungry customers.

"In addition, these companies should continue to receive additional revenue from consumers who normally shop at specialty stores, but can no longer afford to.

"Consumers may not be shopping at Sharper Image any more, but there are other creature comforts that will be difficult for Americans to abandon.

"Coca-Cola (NYSE: KO) and PepsiCo (NYSE: PEP) will still sell products during a prolonged downturn. In addition, companies providing toiletries and convenience like Procter and Gamble and CVS Pharmacy stand to do well during a shifty economy.
