Updated from July 21 eBay ( EBAY ) blew through analysts' quarterly estimates after the close Wednesday. But as feared, the company offered guidance that wasn't up to Wall Street 's heady forecasts and shares tumbled, recently down $2.89, or 3.8%, to $73.71, although off their earlier low of $71.45. The online auction giant earned $190.40 million, or 28 cents a share, in the second quarter. The company's earnings more than doubled its profits of $91.87 million, or 14 cents a share, from the same period last year. eBay's revenue rose 52% to $773.41 million. Analysts were expecting earnings of 25 cents a share on sales of $769.33 million, according to Thomson First Call. In April, eBay said that it expected to earn 24 cents a share on up to $760 million in revenue in the second quarter. But the company's outlook for the third quarter and the rest of the year wasn't as bright as analysts had hoped. For the third quarter, eBay forecast earnings of 24 cents a share on $770 million in sales.
