When a company posts its best-ever operating margin and the stock still tumbles, something else is doing the talking. Amazon.com Inc. (NASDAQ: AMZN) reported after the close on Oct. 29, and the market was quick to judge. Its shares were down more than 7% in pre-market trading the next day, around 20% below the record high they set in August.
The timing in particular will sting. Amazon is heading into the holiday period, usually its biggest quarter of the year, with its share price back where it sat almost two years ago. And it got there despite a quarter in which AWS, its key cloud division, had its strongest run in years.
