Amazon.com rang up a $252 million profit in the third quarter, more than three times the $79 million it reported a year ago, as it cashed in on growth in its cloud computing division and sales in its flagship e-commerce business.

The company Thursday reported that its revenue soared to $32.7 billion, a 29 percent increase from the same period a year earlier. Still, the report put the brakes on a long hot streak for Amazon’s stock, which had soared more than 20 percent so far this year. Analysts expected greater than the 52 cents per share earnings that the company posted, and investors sent the stock down about 5 percent in after-hours trading.
