SAN FRANCISCO—Microsoft Corp. regained its spot as the second most valuable U.S. company on Oct. 26 after a disappointing quarterly report from Amazon.com wiped $65 billion off the online retailer’s market capitalization.
Apple Inc. 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.
