Analysts believe that the world's largest retailer, US group Wal-Mart, is far better equipped to shake off the world's economic difficulties than its sector peers, and have recommended investors buy the group's shares.

In a research paper, a retail analyst with leading US bank JP Morgan, Shari Erberts, said that investors should buy the company's stock because "Wal-Mart's fundamentals far outpace its peers".

Erberts added that Wal-Mart's straightforward food focus was a safe bet in times of economic uncertainty and low consumer confidence: "We are adjusting our ratings to reflect a changed world, where sales and earnings risk have escalated, especially for those companies whose goods are more discretionary."
