RETAILING

Wal-Mart Debt Reviewed for Possible Downgrade: Expecting slower growth from weak consumer demand, Moody’s Investors Service is reviewing about $8.6 billion in long-term debt for the nation’s No. 1 retailer. Under review are ratings for senior unsecured obligations rated Aa1, secured bonds at Aa1 and participating mortgage certificates at Aaa. Shares of Bentonville, Ark.-based Wal-Mart Stores Inc. rose 12.5 cents to $23.75 on the New York Stock Exchange. Moody’s expects annual sales to remain strong, exceeding $90 billion, but with growth likely to come from supercenters and investments in overseas markets, which mature relatively slowly.
