Microsoft tops Exxon to become world's 2nd most valuable company

SAN FRANCISCO - The bull run in Microsoft's (MSFT) stock this past year has helped the tech giant surpass Exxon Mobil (XOM) and seize the rank of the second most valuable company, behind Apple (AAPL).

Under new CEO Satya Nadella, Microsoft has worked to overcome its reputation as a clumsy behemoth struggling to keep up with new tech trends and consumer habits. Nadella has cut expenses , and jobs, while pledging to refocus the company on mobile technology and cloud computing. His efforts have fueled a stock surge that drove Microsoft's total market value above $410 billion on Friday. That leapfrogged Exxon's value of $404 billion, which has been dinged by the drop in oil prices.

"Microsoft has made a strategic change," said Daniel Ives, a tech analyst at FBR Capital Markets. He said Nadella still faces challenges with a company that's heavily reliant on the declining personal computer market. But compared with other longtime tech stalwarts, such as IBM, Hewlett-Packard and Oracle, "Microsoft has done the best job of trying to skate where the puck is going," Ives said.

Apple is the world's most valuable company, with a market capitalization of more than $668 billion. That's more than the $616 billion that Microsoft was worth when it was No. 1 in December 1999. Microsoft shares fell sharply the next year.

But the Redmond, Washington, company has earned greater cachet on Wall Street over the last 18 months. Its stock has risen nearly 70 percent since April 2013, when activist investment firm ValueAct Capital announced it had taken a $2 billion stake in the company and would scrutinize its strategy. Within a few months, longtime CEO Steve Ballmer announced plans to retire. The move was described as unrelated.

Since then, Nadella has announced new initiatives to expand in cloud computing, which promises to be more lucrative than the traditional model of selling software that is installed on clients' computers. Microsoft has also promised a redesign of its flagship Windows operating system and released versions of other popular software for smartphones and tablets, including devices made by competitor Apple.

Microsoft shares have outperformed the tech-heavy NASDAQ Composite Index, which gained about 45 percent in the same 18-month period. The stock hit $50.04 on Friday, its highest point since early 2000, before slipping to the $49.50 range in afternoon trading.
