Remember that old bit about watching out for falling prices?
Well, shares of Wal-Mart Stores hit an all-time high of $74.80 on July 27, having recently pierced levels they haven’t visited since 1999. The stock’s 25 percent year-to-date return is nearly triple that of the Standard & Poor’s 500 index. Over the past 13 years, the chain that put Bentonville, Ark., on the map went from earning $4.4 billion on $137 billion in revenue to now clearing $16 billion on sales of $446 billion. Unemployment has since more than doubled from its New Economy-charged days of 4 percent.
