Microsoft's market capitalization topped $500 billion for the first time since 2000 on Friday, after the technology giant's stock rose following another quarter of results that beat Wall Street's expectations. From a report: Shares of the world's biggest software company rose as much as 2.1 percent to $65.64, an all-time high, in early trading, valuing the company at $510.37 billion. The last time Microsoft was valued more was in March 2000, during the heyday of the dotcom era, when it had a market value of a little above $550 billion, according to Thomson Reuters data. Despite the gains, Microsoft still lags Apple's market capitalization of about $642 billion and Google-parent Alphabet's market value of a little more than $570 billion. Microsoft reported second-quarter results on Thursday that beat analysts' average estimate for both revenue and profit, mainly due to its fast-growing cloud computing business. The company's profit and revenue have now topped Wall Street's expectations in seven of the last eight quarters.
