Retail analysts expessed cautious optimism after a surge of holiday buying by weekend shoppers. Early sales data from ShopperTrak, which measures store traffic for clients, showed Friday sales rose 10.8 percent from those of a year ago, to $8 billion.

As expected, stores were quieter Saturday. Tempering optimism was a report by Wal-Mart Stores, the world's largest retailer, that it was lowering its November sales estimates.
