An anonymous reader shares a report: Microsoft's value is returning to tech-bubble peaks. The software giant closed with a market value of $600 billion Thursday for the first time since January 2000, according to the Journal's Market Data Group. Shares rose 0.4 percent to $77.91, setting a fresh all-time high. For the year, Microsoft shares are up 25% and on track for their best year since 2013, as the firm continues its rebirth as a force in cloud-computing. The firm is the third-largest S&P 500 company in market value, trailing Apple (about $800 billion) and Google's parent company, Alphabet, (about $690 billion). In July, fellow technology and internet stalwarts Facebook and Amazon.com joined the trio as the only U.S.-listed companies valued at more than in the $500 billion. The last time Microsoft was over $600 billion back in 2000, it didn't stay there for long. The tech bubble would peak in March of that year, and the Nasdaq Composite Index wouldn't climb back to the level it reach that year until 2015.
