SAN FRANCISCO -- Apple ( AAPL) shares jumped to new all-time highs after strong quarterly results showcased the company's unfolding growth prospects. In recent trading, the stock had climbed $11.21, almost 6.5%, to $185.57, one day after the company reported a blockbuster quarter for U.S. and European sales of its core products, particularly its Mac computers and its newest franchise, the iPhone. The results support investors' hopes that Apple has reinvigorated its Mac business and is establishing a beachhead in the cell-phone market as its brand becomes a must-have for digital lifestyles in the U.S. and abroad. U.S. revenue grew at a brisk 25%, but was overshadowed by growth overseas. Sales in Europe rose 36% to $1.34 billion, accounting for 22% of total revenue, mostly from the strength of the Mac and the company's iPod portable music player. Chief Operating Officer Tim Cook said there's "substantial evidence" that sales across the Atlantic have increased as the iPod's popularity introduces more people to Apple products. The company has just 10 stores in the U.K. and one in Rome, but its iTunes music service is available in the local languages of 22 countries, many of which are in Europe. In November, Apple will begin selling the iPhone in the U.K., Germany and France. According to Cook, Apple's sales grew 52% in Asia, outpacing other geographic regions, albeit off a smaller base. The company has struggled in Japan, however, where sales fell 11%. But Apple's plans for Asia may hinge more on the region's emerging markets. The company is planning to open a store in Beijing.
