SAN FRANCISCO- Microsoft Corp (MSFT.O) regained its spot as the second most valuable US company on Friday after a disappointing quarterly report from Amazon.com (AMZN.O) wiped $65 billion off the online retailer’s market capitalization.

Apple Inc (AAPL.O) tops the list at over $1 trillion after crossing that threshold in September. Microsoft’s market capitalization was Wall Street’s highest in late 1998 through early 2000 before the dot-com bubble burst.
